The role of time perspectives and impulsivity dimensions in coping styles
PublicationBoth time perspectives and impulsivity dimensions are groups of traits that are connected to self-control abilities and might be important for coping styles. However, to date, no study has systematically investigated their utility in predicting coping styles with regard to their multidimensional nature. The current study was correlational and exploratory, aiming to discover what amount of variance in each of the three coping...

THE ROLE OF NATURE IN PLACEMAKING WITHIN THE LIMITS OF HISTORIC CITIES
PublicationThis paper focuses on the role of nature in placemaking within historic cities. There are two different approaches to placemaking – The first is a more traditional approach, i.e. complete building process which entails significant investments. The second is “Lighter, Quicker, Cheaper” approach proposed by the Project for Public Spaces organization. This article discusses the role, importance and place of nature in both approaches....

Fatigue and burnout in police officers: the mediating role of emotions
PublicationPurpose – The policing profession is associated with psychosocial hazard. Fatigue and burnout often affect police officers, and may impair the functioning of the organization and public safety. The relationship between fatigue and burnout may be modified by job-related emotions. While negative emotions have been extensively studied, the role of positive emotions at work is relatively less known. Additionally, there is insufficient...

Positron binding to alkali-metal hydrides: The role of molecular vibrations
PublicationThe bound vibrational levels for J=0 have been computed for the series of alkali-metal hydride molecules from LiH to RbH, including NaH and KH. For all four molecules the corresponding potential-energy curves have been obtained for each isolated species and for its positron-bound complex (e+XH). It is found that the calculated positron affinity values strongly depend on the molecular vibrational state for which they are obtained...
