Nowadays, collaborative learning is proving to offer solutions to new inclusivity research challenges, and most importantly, can help ensure sustainable education. Collaborative learning can strengthen positive attitudes towards learning, improve performance in academic results, and enhance self-esteem, by promoting interaction and mutual support among young people. Extended reality (XR), associated with collaborative learning, offers a further advantage by facilitating deep comprehensive learning. An online survey was conducted to investigate respondents’ views on the impact and influence of virtual technologies on work, study, and social life. Respondents (n = 1032) were recruited from Serbia, Romania, and Hungary, from five public and private universities. The study reveals students’ perceptions of e-learning and XR immersion. The data were analyzed by using a combination of descriptive techniques from PSPP (GNU open source SPSS—Statistical Package for the Social Sciences, Free Software Foundation, Boston, MA, USA), and by designing a regression model to evaluate the work-life balance. This regression model shows that the work-life balance is positively influenced by the inclusion of XR facilities in the e-learning process, along with an increased level of culture and living standard. The higher living standard of a student is associated with higher digital competence and more financial resources available to invest in technology.

Groundwater pollution is a very common problem worldwide, as it poses a serious threat to both the environment and the economic and social development and consequently generates several types of costs. The analysis of pollution control involves a permanent comparison between pollution costs and the costs associated with various methods of pollution reduction. An environmental policy based on economic instruments is more effective than an environmental policy focused on command and control tools. In this respect, the present paper provides a case study showing how anthropogenic factors such as wastewater, industrial, agricultural, and natural factors are able to change the physical and chemical parameters of groundwater in the study area, thus endangering their quality. In order to monitor the groundwater quality in the region of Dobrudja, an analysis of physico-chemical parameters was performed. The content of heavy metals was analyzed and the health risk index was taken into account and analyzed, in order to set a better correctness of the metal content from the underground waters. Studies on groundwater quality control have shown that, in many parts of the world, water has different degrees of quality depending on the natural and anthropogenic factors acting on the pertaining environment. This is why more attention should be paid to the prevention of groundwater pollution and the immediate remediation of accidents.

The association of the term ‘educational’ to the term ‘marketing’ generates a specialized domain, by applying methods, politics and marketing strategies in the area of education. Due to the cultural, social and complex role of the education, educational marketing represents a part of the services marketing, the social marketing and the non-profit organizations. By offering mandatory educational services, financed from the state budget, the school units, through their activity, respect the principles of social marketing, regardless of the financial benefits that result from the provision of these services. This article aims to place educational marketing below the conceptual level in the field of service marketing; the reference works in the field of educational marketing are not many, a consequence of the fact that this is a new field.

This paper aimed to identify and analyze the perception of Romanian PhD students on the quality of higher education services by proposing to identify, based on data collected through an online survey and SERVPERF model, the most important features of higher education services in the PhD students view. PhD students consider it important in education, both equipped classrooms, seminaries, laboratories and libraries, as well as matters relating to teaching, relationships with teachers and university secretary. This research can be extended to another aimed at analyzing the perception of teachers and administrative staff from Romanian universities on service quality, because only the study of all those involved in higher education process can outline the most appropriate model for the Romanian universities

More and more universities are striving to provide competitive education programs to help graduates integrate into market areas. In this fight, universities need to have strong communication and support in the business world. The purpose of this article is to identify the main factors that would improve the quality of the doctoral program and facilitate the integration of students into the labour market in Romania. A questionnaire was applied to PhD students from the universities in Bucharest, and the data collected were interpreted.The linear regression model developed shows that the library facilities, school infrastructure, access to Doctoral Theses, dialog between academia and students, doctoral coordinator and committee proficiency, staff attitude and multiple way of communication are some important factors that have positive influence over the quality of the higher education in the PhD program and the students’ integration on labour market in Romania. The open questions of survey revealed new interesting suggestion for improving PhD programs in Romania.
