The first aim of this research is to introduce and to validate the new concept of School Normative Context, that revisits
the concept of School Moral Atmosphere studied by Brugman and his colleagues through the SMAQ (1999) and validated also in
the Italian context (Mancini & Fruggeri, 2005). The School Normative Context entails two new aspects: The first one concerns
the interactive dimension of each specific school context and the second one concerns the perception of responsibility (internal
vs, external) in the implementation of the norm. The second aim is to study the relation among adolescents perception of School
Normative Context, adolescents’ orientation towards social rules and their aggressive behaviours against classmates at school.
268 students (mean age 17,01) attending three Italian high schools of three different educational levels (Lyceum, technical
and professional) participated in this research. They filled a questionnaire composed of three parts: School Normative Context
Questionnaire (SNC), Normative Orientation Scale (NOS) and Aggression Scale (Orpinas, Frankowski, 2001). School Normative
Context has shown an acceptable degree of conceptual and predictive validity. The research has shown that the School Normative
Context has an influence on the aggressive behaviours against classmates. Furthermore, it is a mediating factor between the
adolescents’ orientation towards social norms and their aggressive behaviours at school. 相似文献

There is currently a growing interest in control of stretching of DNA inside nanoconfined regions due to the possibility to analyze and manipulate single biomolecules for applications such as DNA mapping and barcoding, which are based on stretching the DNA in a linear fashion. In the present work, we couple Finite Element Methods and Monte Carlo simulations in order to study the conformation of DNA molecules confined in nanofluidic channels with neutral and charged walls. We find that the electrostatic forces become more and more important when lowering the ionic strength of the solution. The influence of the nanochannel cross section geometry is also studied by evaluating the DNA elongation in square, rectangular, and triangular channels. We demonstrate that coupling electrostatically interacting walls with a triangular geometry is an efficient way to stretch DNA molecules at the scale of hundreds of nanometers. The paper reports experimental observations of λ-DNA molecules in poly(dimethylsiloxane) nanochannels filled with solutions of different ionic strength. The results are in good agreement with the theoretical predictions, confirming the crucial role of the electrostatic repulsion of the constraining walls on the molecule stretching. 相似文献

Students' opinions about the opportunities and the implications of VR in instruction were investigated by administering a questionnaire to humanities and engineering undergraduates. The questionnaire invited participants to rate a series of statements concerning motivation and emotion, skills, cognitive styles, benefits and learning outcomes associated with the use of VR in education. The representation which emerged was internally consistent and articulated into specific dimensions. It was not affected by gender, by the previous use of VR software, or by the knowledge of the main topics concerning the introduction of IT in instruction. Also the direct participation in a training session based on an immersive VR experience did not influence such a representation, which was partially modulated by the kind of course attended by students. 相似文献

This registered report evaluated the efficacy of an Italian adaptation of the Identity Project, a school-based intervention promoting adolescents' cultural identity. Migration background and environmental sensitivity were explored as moderators. After adapting and piloting the intervention, a randomized controlled trial was conducted between October 2021 and January 2022 on 747 ethnically diverse adolescents (Mage = 15 years, 53% girls, 31% with migration background) attending 45 classrooms randomly assigned to the intervention or control condition. Bayesian analyses confirmed the efficacy of the Italian IP in enhancing exploration processes (Cohen's d = .18), whereas no cascading effect on resolution emerged. Youth with higher (vs. lower) levels of environmental sensitivity benefited more in terms of exploration. Implications for developmental theory and practice are discussed. 相似文献
