Assessment of the activities of private universities in the context of quality management in 2010
Open Research DataIn all universities, the assessment of the quality is made by the supervisor, the opinion of students and the admission of classes have the greatest impact on the assessment of the quality of education. Subsequent tracking of the student's fate has a slightly smaller impact on the grade. Research also shows that only 4 out of 7 respondents monitor the...

Self-Censorship in a Workplace: The Role of Gender, Management Position, Procedural Justice and Organizational Climate
Open Research DataData consist of three studies. In study 1 (N = 948) we test whether women manifest more self-censorship than men and we verify whether this effect is maintained when women and men hold managerial position. Then, we analyse the effects of procedural justice (study 2, N = 98) and communal organizational climate (study 3, N = 567) on women’s and men’s...
