| 2025 | Ethical Considerations and Responsible Use of AI in Education: A Students' PerspectiveabstractArtificial Intelligence (AI) has gradually become an ever-increasing feature of today's society through an ongoing and often nonlinear diffusion of AI-powered applications. Education couldn't be an exception, where we observe utilisation of AI for different purposes, varying from adaptive learning platforms to content creation, translations, virtual tutoring, and enhancement of learning support, among others. In the light of such developments, nevertheless, ethical implications should be revisited. The increasing use of Artificial Intelligence in Education invites commentators to explore practices of responsible use and ethical considerations. For example, transparency, data privacy, protection, bias and fairness are just some of the ethical considerations that need to be addressed at the intersection of AI and education. The current paper explores the relationship of AI and ethics for students in a Cypriot University. The analysis draws on the findings of a survey conducted among students to identify what ethical requirements and considerations are aware of amidst ongoing AI use. A number of important practical implications stem by the findings that may be important for educators and university administrators. Among others, the findings suggest that although students are not very knowledgeable about data privacy and ethical implications, they still have a sense about the importance of protection - something that underlines the role of Higher Education Institutions in training and guiding learners in their AI-powered learning journey.

| 2025 | Exploring Students' Familiarity, Usage Patterns, and Perceptions of Generative AI Tools in EducationabstractThis study explores students' familiarity, usage patterns, and perceptions of Generative AI (GenAI) tools, focusing on their potential applications in education. Using a structured questionnaire, data were collected from 167 respondents to assess familiarity with AI, GenAI, and specific interfaces such as ChatGPT, Dall-E and Google Gemini. Findings indicate that while most respondents are somewhat familiar with AI and GenAI, familiarity with specific tools varies significantly, with ChatGPT being the most recognized and used. Text-based tools dominate usage, primarily for tasks like explaining concepts, summarizing content, and translation. Challenges encountered include issues with accuracy, ease of use, and instruction specificity. Despite these challenges, respondents identify personalized learning resources, automated grading systems, and virtual tutors as the most valuable educational applications. The study highlights the transformative potential of GenAI in education while underscoring the need for improved tool design and expanded training to optimize its adoption.

| 2025 | Exploring Experiences and Perceptions of Artificial Intelligence and its Business Applications by University StudentsabstractArtificial Intelligence (AI), a transformative, multifaceted force is gaining recognition for its potential impact on all aspects of business; its applications can vary, depending on the specific industry and firm. The present study assesses the AI awareness of 4 0 doctoral students attending an international summer school program regarding the value of AI applications in improving business processes, and cost effectiveness. The participants responded to an online survey after the completion of the program. The results indicated that the participants strongly prefer automation, secure and cost-effective processes which they claim lead to improved and increased competitiveness. Although they also value the accuracy and speed of several applications such as ChatGPT and other LLMs, they also expressed concern, about data privacy, security, ethical implications, biases and regulation. In addition, they stated concerns about AI's impact on human dignity and the likelihood of wealth inequality, stating that AI may widen global inequality, exacerbating inequality both between countries and within-countries. Furthermore, one fourth of the participants indicated that what hindered their place of work to implement AI applications was the high initial cost, fear of security risks, loss of jobs contributing to colleagues' unemployment, and lack of AI specialized skills, as they are witnessing an AI skills gap. Moreover, the participants in terms of human communication, commented on AI's capability of absorbing immense amounts of information quickly and efficiently, however, human language, human communication is so unique that it cannot be replicated by any other species; AI has no idea what it is saying or writing, thus leading to loss or dramatic reduction in human communication. They believe that AI in business should serve as a driver for innovation and growth, contributing to decision-making enhancement and its successful integration into various business functions, covering all business transactions. Embracing with caution AI within an innovative organizational culture is of utmost importance for any industry. The findings of the current study underline AI's value and recommend to leverage its benefits. The findings also serve as guides for universities curriculum development and modification to accommodate stated concerns. Maria Michailidis, Despo Ktoridou, Charalambos S.

| 2024 | Students' Social Media and Content Development Practices: Evidence from a University in CyprusabstractTechnological advancement goes through ongoing alterations, re-writing the rules and norms of social relationships among members in society. One area that has particularly affected behaviors in the last few years is the use of social media. Many people use social media for communication with friends and relatives, news sharing, being informed about world events, posting personal stories etc. Within this context, the current paper explores diverse aspects related to the selection and usage of social media along with practices related to user-generated content by university students. More specifically, topics such as which social media are used more often and for what reasons, frequency of usage and posting on social media, network size, types of user generated content are explored. The analysis draws on findings collected through a survey from learners at all levels of higher education. While some of the findings resonate with existing studies, such as the popularity of Instagram and Facebook, the relatively long hours young people spent on social media and the importance of connecting with friends and family, other findings are quite unexpected, including responders' preferences for physical rather than online interaction with followers, as well as the rise of real names in social media as opposed to pseudonyms and anonymity.

| 2024 | Exploring Metaverse Learning Knowledge and Acceptance: A Study of Students' Opinions in Higher EducationabstractThe Metaverse technology is an innovation that is expected to have far-reaching effects in many areas of life, including education. It could potentially significantly change the way education is provided, by enabling immersive teaching and learning experiences in both virtual and conventional class environments. A key aspect of its potential adoption concerns the extent to which learners consider it useful and easy to use. This paper aims to contribute to the understanding of Metaverse utilization through a study of students’ opinion in a Cypriot University. The study investigates the level of students’ knowledge about the Metaverse, what educational activities they are interested in engaging in and their perceptions of a Metaverse as a Learning Environment ease of use and usefulness. Results suggest that the majority of students are aware of the term Metaverse but do not know much about working in such a learning environment. Moreover, they are interested mainly in doing experiments that are dangerous in real life, learning languages and using it for 3D simulation. At the same time, they have a relatively positive perception of its usefulness and ease of use. Despo Ktoridou, Epaminondas Epaminonda, Leonidas Efthymiou, Maria Michailidis |

| 2023 | Fostering an Ethical and HR Management Mindset for Tomorrow's TechnologistsabstractIn the light of increasing digitization, organizations, trade unions, human resource practitioners and other stakeholders need to evaluate the changes brought by technology diffusion on employment. This is because technological transformation is often linked to employment controversies and challenges. Varying from worker-monitoring and loss of privacy, to fewer employment opportunities and replacement of humans by machines, technology is behind some of the tensions appearing today in labor relations and human resource management. Within this framework, the purpose of the paper is to examine how technology students perceive technology-led change, its possible impact on human resources, and whether curriculum should include ethical dimensions to better prepare them for their future career. In other words, does Digital Transformation necessitate a change in education so that students (and future technology graduates) get equipped with the necessary ethical mindset and human resource management skills? Following this line of thought, the current study is conducted at the intersection of digitization, human resource management, and business ethics. The analysis draws on the findings of a survey, conducted among undergraduate and postgraduate technology students in December 2022. A number of important practical implications stem by the findings, which can be linked to existing learning strategies and pedagogy.

| 2023 | Is Education Ready To Embrace Metaverse?abstractMetaverse, an immersive virtual world that is facilitated by the use of virtual reality (VR) and augmented reality (AR), is expected to be soon part of our lives. Indeed, in some areas, such as in the game industry, this revolutionary technology is already being used. In the context of education, however, metaverse is not yet being extensively utilized and its possible usage is currently being debated. To contribute to this debate, the current study explores students' and educators' perceptions of metaverse and its potential to be used in education. To study these questions a mixed research approach was employed combining both quantitative and qualitative data collection. Specifically, an online questionnaire was distributed to students and semi structured interviews have been conducted with lecturers. Results suggest that students and teachers have a relatively good understanding of metaverse and foresee its utilization in education in the next few years. They remain open about the extent to which this will happen and divided as how fundamental a change it will be. Despo Ktoridou, Epaminondas Epaminonda, Leonidas Efthymiou |

| 2022 | The four business models for AI adoption in education: Giving leaders a destination for the digital transformation journeyabstractEffective digital transformation requires new technology to work in harmony with the people towards a common goal. All the universities do not have the same capabilities currently across these three parameters and may not be able, or willing, to develop them in the same way. Therefore, several alternative models conducive to digital transformation and AI adoption must be identified. A university must not have to go on this journey without a roadmap. There should be several education business models that optimize AI adoption to choose from. Identifying the destination in advance reinforces the trust between the digital transformation leader and the followers. This research identifies four education business models that are optimized for AI. The first is focus and disaggregate. The second is to keep the existing model but enhance it with AI. The third is an educator expanding beyond their current model and the fourth is a disruptor entering education. Alex Zarifis, Leonidas Efthymiou |

| 2021 | A model for experiential learning by replicating a workplace environment in virtual classesabstractExperiential learning has been a core notion in higher education for nearly half a century. However, the application of experiential learning practices on virtual classes is somewhat limited. In this paper, we test different practices of experiential learning intended for online learning. We draw on electronic end-of-module surveys, which have been completed by students upon completion of the class. The sample concerns the completed questionnaires of 197 post-graduate students. Based on these findings, we present a three-pillar model which relies on a) online communities, b) learning-by-doing as part of continuous assessment and, c) multicultural teamwork, to promote experiential learning by replicating a `workplace environment'.

| 2021 | COVID-19 Contingency Plans: The Impact on Students' Future ChoicesabstractThis paper explores the views and experiences of students after the transition from face-to-face to online learning as a result of Covid-19 contingency plan. Most importantly, almost a year since the transition, the study explores the perceived student benefit or loss that occurred through online learning - in a private university in Cyprus. Also, the study examines how the transition is likely to influence students' future education choices. A computer-administered questionnaire was sent to undergraduate students in the field of computing and management. The findings suggest that although students enjoyed several aspects of online learning (such as the recorded lecturers), the overwhelming majority believes that face-to-face is superior. The results of the study may assist educators adjust or enrich their post-pandemic learning offerings accordingly. Epaminondas Epaminonda, Leonidas Efthymiou, Despo Ktoridou |

| 2021 | In-Campus Work and Study: Motivation, Challenges, Benefits, Skills Developed and Impact on StudiesabstractThis paper analyzes technology major students' experience in combining in campus work and study. Using structured interviews, it examines the factors influencing students' choice, the challenges and benefits of the experience, the skills developed and the impact on their studies. Results suggest that students choose to work for financial reasons and for gaining work experience, but also because of lecturer encouragement. Regarding the challenges in working and studying, the main one was managing time, while benefits include gaining work experience, widening social circle/socialization and putting in practice what was learned in class. The main skills developed were time management, critical thinking and problem solving, written and verbal communication, and teamwork. Finally, the impact on studies is mostly seen as positive since, despite time pressures, students feel that work has helped them appreciate the application of theoretical knowledge gained in class and made them more organized and improved their ability to work with deadlines.
