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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
