Even though the historical development of artificial intelligence started in the mid-20th century, since the launching of Chat GPT this concept emerged in the scientific and educational agenda. Different concerns are arising at different education levels, starting from a discussion about whether should it be considered plagiarism, and ending with ethical aspects of the usage of Chat GPT by students and educators. The research aims to research the main recent scientific findings about generative tools in artificial intelligence and the ethical aspects of its usage in education. Methods used – analysis of recent scientific findings and statistical analysis of the answers of the respondents on authors created a survey for students of Higher Education Institutions about their attitudes and knowledge towards Generative Tools of Artificial Intelligence. Analysis was performed via SPSS comparing the opinion of students towards ethics of Generative Tools of AI from different countries. Results of the research show the attitudes of students towards the usage of Generative Tools of Artificial Intelligence from different countries.

Since generative tools of Artificial Intelligence appeared in education, ongoing discussion arose. Still, higher education institutions argue if generative tools can be used, and if yes, what exactly can be accepted. The purpose of this study is to investigate for what exactly students use the generative tool Chat GPT in their studies, as well as to determine if there is a statistically significant difference between students representing different fields of study in terms of usage of Chat GPT in general, as well as in evaluation of the knowledge. The objectives of the study are to research recent scientific findings, as well as to analyze the results of the survey created by authors, which was distributed in Latvia, Lithuania, Ukraine, Bulgaria and Uzbekistan. Methods of the study are analysis of the recent findings and statistical analysis of the survey. To test hypotheses, the authors employed the Kruscal-Wallis non-parametric test for both hypotheses, where authors tested if there are statistically significant differences between answers of students from different education fields. The final results highlight the use of Chat GPT by students in higher education.

Sustainability has become an integral part of business strategies, influencing both operational decisions and customer choices. As people become more aware of environmental and social issues, many are looking for hospitality services that align with their values. But how much do sustainability efforts actually influence customers' choices of where to stay? This study explores this question by analysing whether sustainable practices in the hospitality industry influence consumer preferences. In order to comprehend the aforementioned correlation, the authors of this study conducted a survey with the objective of acquiring insights into customer attitudes towards sustainability in the hospitality industry. The survey encompassed pivotal domains such as eco-friendly initiatives, energy efficiency, waste reduction, ethical sourcing, and corporate social responsibility (CSR). Utilising the statistical software SPSS, the authors employed descriptive statistics and Kruskal-Wallis non-parametric tests to examine whether hotel sustainability practices have a greater impact on the decision-making process of customers with higher education compared to those with lower education levels. The findings of the study demonstrate that sustainability is a significant consideration for customers. Individuals are more inclined to select hotels that demonstrate a commitment to meaningful sustainability initiatives. Moreover, the data indicates that consumers with a higher educational background place a greater value on sustainability when making their decisions. This research underscores the mounting significance of sustainability as a competitive advantage in the hospitality sector. Companies that integrate strong and transparent sustainability practices not only help the planet, but also attract a more loyal and conscious customer base. These findings provide valuable guidance for hospitality managers and policymakers, emphasising the need for sustainability initiatives that are both impactful and well communicated.

Since the late 20th century, organisational culture has attracted considerable attention from researchers worldwide, becoming a key subject of academic inquiry. In the context of higher education, organisational culture has been shown to exert a significant influence on institutional development and workplace dynamics. A comprehensive grasp of this concept empowers university administration to cultivate a professional environment conducive to the success of faculty and staff. The present study explores theoretical perspectives on organisational culture and examines the views of academic staff across various countries regarding key aspects of institutional culture. A particular focus is placed on faculty self-assessments of their perceived appreciation by both university management and students. The research methodology encompasses an analysis of scientific literature and a survey of teaching staff with regard to organisational culture in higher education. The analysis of data involves the utilisation of descriptive statistics, cross-tabulations, hypothesis testing through the implementation of t-tests, analysis of variance (ANOVA), and correlation analysis. The findings provide insights into the core values upheld by higher education institutions from the organisational culture perspective, offering a deeper understanding of faculty experiences and institutional practices.

Research purpose.: The research purpose of this paper was to explore the evaluation of skills by academic staff to improve the quality of the administration process in higher education institutions (HEIs) from two perspectives. Firstly, the authors investigated whether there are statistically significant differences between the genders of academic staff in higher education institutions regarding the evaluation of their skills and competencies. Secondly, the study aimed to determine if there are statistically significant differences in competencies perceived between academic staff of STEM sciences and those with academic experience in other sciences in terms of assessing their professional competencies. The purpose was determined by the impact of self-assessment of professional competencies on the improvement of administrative processes. Design / Methodology / Approach.: The survey, using the authors` developed questionnaire, was distributed in Ukraine from 2019 to 2023. 374 respondents were surveyed. To test hypotheses, the authors employed the Mann-Whitney U test for gender-related hypotheses and the Kruskal-Wallis test for hypotheses related to the area of scientific and academic activities. Findings.: Due to the analysis carried out in the present research, the Mann-Whitney non-parametric test showed that there is no statistically significant difference between the gender groups and their professional competencies evaluation, which leads to the rejection of the first hypothesis. The second hypothesis was also rejected, as based on the Kruskal-Wally’s test there is no statistically significant difference between the perception of the professional competencies among the academic staff of STEM and other sciences. Originality / Value / Practical implications.: Unlike other studies, this research specifically focuses on the differences between the self-assessment-based perceptions by genders and STEM sciences academic staff compared to representatives of other branches of science at HEIs in Ukraine. The practical value is achieved by the research thus ensuring administrative staff with defined competencies and self-assessment criteria. The research findings then will allow us to link competencies to administration processes and offer training and development opportunities based on identified competency gaps. The feedback mechanism might be established based on the research data and these self-assessment results might be incorporated into the performance evaluation processes, thus improving the quality of the educational process and its administration in HEIs. Practical implications are related to the state and period of the research, due to the present war in Ukraine.
