Our study aims to identify students’ attitudes towards the use of mobile technologies (MT) during learning activities in higher education. Data were collected using the Mobile Technologies Questionnaire/MTQ, a ten-item brief questionnaire that was designed to determine attitudes towards the use of mobile technologies in the learning process among university students and academic staff. The MTQ was completed by 575 students from a state university in the northeastern region of Romania. Exploratory and confirmatory factor analyses revealed two latent factors: MT facilities for study resources and communication and MT facilities for learning. Along with general analysis of the statistical indicators regarding the attitude towards the use of MT, the relationships between the use of MT and five socio-demographic variables (gender, age, place of residence, year of study, academic status and study program) were analyzed. Comparative data showed some statistically significant differences but with small or modest effect sizes, depending on age, year of study, place of residence, academic status and the study program in which the students were enrolled. This study provides additional support for the construct validity of a brief tool that was designed to measure students’ attitudes towards the use of MT during learning activities carried out in higher education.

The purpose of this study is to elaborate and validate a scale for the evaluation of the teachers’ attitude towards quality management, by integrating elements of online education. Nine hundred and forty-two teachers from Romania have participated in the study. The exploratory factor analysis has led to the identification of three main dimensions of the scale: (1) communication and alignment; (2) needs and opportunities; and (3) training and support. Teachers participating in managing positions or in quality assurance boards indicated a more positive attitude towards the three components. Furthermore, teachers of a higher teaching experience reported higher values in the needs and opportunities component. The results are useful to educational institutions, program designers and policy makers to evaluate the teachers’ attitude towards quality management.

This study examines fish communities in the heavily impacted Bistrița River, located in the Eastern Carpathians of Romania, where diffuse pollution from mining, domestic wastewater, agricultural and forestry activities emerged as the most severe pressures. Fish sampling was conducted at twenty sites across two Natura 2000 protected areas. Results showed that species richness and diversity were higher downstream (Z1–Z5), indicating improved ecological conditions compared to the upstream section (B1–B15). The fish-based Index of Biological Integrity (IBI) suggested overall good biological integrity, with excellent conditions (class I) recorded in 70% of sites. Redundancy analysis (RDA) further revealed that elevation and conductivity significantly shaped community structure, while the site-specific impact score had only marginal effects. To assess water quality and biotic integrity based on different communities, as required by the Water Framework Directive (WFD), five sites were selected for parallel sampling of diatoms and benthic invertebrates. Among these, zoobenthos proved the most sensitive to water quality degradation, with biotic indices indicating classes I to III. These findings demonstrate that assessments based solely on fish may underestimate ecological impacts, underscoring the need for complementary approaches that account for multiple biotic communities when monitoring riverine ecosystem health.
