The concept of flow is briefly reviewed and several theoretical and methodological problems related to flow research are discussed. In three studies, we attempted to avoid these problems by measuring the experience of flow in its components, rather than operationally defining flow in terms of challenge and skill. With this measure, we tested the assumption that experience of flow substantially ...

In this study hackers’ motivation is investigated, using the flow paradigm. It was hypothesized that flow increases with the increase of hackers’ competence in the IT use. An on-line research was administered within the Russian-speaking community (N=457). The hypothesis was not confirmed: the relationship between hackers’ experience and flow is more complicated than the straightforward correlat...

This study explores the effects of two independent variables: navigation shopping behavior (experiential vs. utilitarian) and interactivity levels (low vs. high) on flow experience, in a laboratory experiment that is a 2 x 2 factorial in a completely randomized design. The experiment deals with two commercial web sites: an original with high interactive features and a custom-made, parallel, and...

BACKGROUND Nursing is a constant balance between strain and stimulation and work and health research with a positive reference point has been recommended. A health-promoting circumstance for subjective experience is flow, which is a psychological state, when individuals concurrently experience happiness, motivation and cognitive efficiency. Flow situations can be identified through individuals'...

This paper reveals the experiences of the application of a software tool that combines discrete event simulation (DES), material flow analysis (MFA) and life cycle assessment (LCA) in a single simulation model. This view focuses not only on economic optimization but also on material flow analysis opening the door to sustainable production in the future. Thus, the software unifies the economic a...

This paper develops and analyzes a simplified model of the dynamics of delay propagation in air traffic networks. The proposed model considers the redistribution of delays by accounting for aircraft flows between airports, the persistence of delays at an airport, the mitigation of delays due to slacks or buffers in flight schedules, and inputs such as sudden impulsive disruptions or sustained i...

At present, high-speed rail is used only as a mode of passenger transport. Yet, the acceleration of logistics and freight transport flows could be compatible with high-speed rail capabilities. This article examines the experiences, literature and prospects of high-speed rail for freight. It uses three hypotheses to evaluate the development of freight high-speed rail services in Europe. The arti...

To date, only few process-based models for subsurface flow treatment wetlands have been developed. For modelling a treatment wetland, these models have to comprise a number of sub-models to describe water flow, pollutant transport, pollutant transformation and degradation, effects of wetland plants, and transport and deposition of suspended particulate matter. The two most advanced models are t...
