This article presents the results of a study carried out with the aim to:(1) analyze secondary school students' and their teachers' ideal representations of classroom justice, (2) deepen the topic of students' sense of injustice, and (3) explore the links between students' perceived injustice and their psychological engagement in school, measured on different aspects (identification with one's own class, learning motivation, dialogue with teachers). A questionnaire was distributed to 400 Italian secondary school students and their 79 teachers. Results show that the representations of ideal classroom justice refer to communication, principle of equality and principles of effort/need, and that the positions of teachers and students on these representations differ. Moreover, students report a rather diffuse and shared feeling of being treated in an unjust manner by their teachers, and this affects their psychological engagement in school. Results are commented on their theoretical, methodological and applicative implications.

Purpose The purpose of this paper is to provide an analysis of how an airport’s business model (BM) has been innovated. In particular, it considers a BM innovation owing to an exogenous driver, i.e. a change in the legislative environment. Design/methodology/approach The paper presents an in-depth case study. It analyses the case of an Italian regional airport that has been renewed by changes in the National Plan of Transport. Findings The paper extends previous research on BM and air transport industry in two ways. First, the authors contribute to Gillen’s (2011) framework, via introducing a new kind of ownership/governance structure, that of long-term concession, characterized by the concession of the comprehensive management to a private company for 30 years. Second, the authors look at how a BM has been implemented and used as a manipulating device over the two phases of the airport development, namely, incubation and generation. Originality/value The paper provides an in-depth case study on an airport BM innovation.
