Evaluation of Professional Demands and Financial Reward Through the Perception of Police Managers
PublikacjaThe aim of the study was to examine the relationship between job demands and salary in the subjective perception of mid-level police managers. An occupational stress model in which effort spent on job demands are not balanced by the received reward, was adopted. The study comprised 51 police officers (4 women). The partial least squares method was used for the analysis, and the SmartPLS 2.0 program was applied. The income and...

A multi-agent method for periodicity detection in distributed events
PublikacjaMulti-agent systems working in constantly changing environments may be challenged by instantaneous unavailability of their autonomous agents caused e.g. by limited computing resources. A new method of self-organization of distributed service components is proposed, suitable for multi-agent systems. This method relies on particular agents carrying out separate analyzes of their individual processing loads or other specific events....

A standard analytical method as the common good and pollution abatement measure
PublikacjaA standard method can be considered as a common-good “resource,” and the solution to “the commons” problems usually lies in societal self-organization. The multi-criteria decision analysis (MCDA) was applied to model complex phenomena, such as the standard selection for imidacloprid determination. In this process, the standard was self-selected by the analytical chemistry society. The results show that analytical chemistry is a...
