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...

The Analysis of Working Parameters Decrease in Photovoltaic Modules as a Result of Dust Deposition
PublicationThe aspect of dust accumulation on the surface of photovoltaic (PV) modules should be thoroughly understood in order to minimize possible obstacles affecting energy generation. Several elements affect the amount of pollutant gathered on the surface of a solar device, mainly its localization, which is irreversibly linked to factors such as annual rainfall, occasional snow coverage, or, in a dry climate, increased blow of dust during...
