Purpose This study aims to examine how gamification increases employees’ knowledge contribution to the place of work. It develops and tests the conjecture that gamification adds hedonic value to the use of an enterprise collaboration system (ECS), which, in turn, increases in both the quality and quantity of knowledge contribution. Design/methodo...
Article
Although gamification in the workplace is burgeoning, organizations frequently have difficulty sustaining user engagement with a gamified information system (IS). The focus of this study is how a gamified IS in the workplace engages users and encourages them to continue system use. By proposing the concepts of flow experience (FE) and aesthetic exp...
Article
Gamification—the use of game elements in non-game contexts—is gaining interest among researchers and practitioners. How gamification enhances user engagement, though, remains unclear, largely due to the lack of a theoretical framework. To narrow the theory gap, this study develops a theoretical model, which draws on cognitive evaluation theory to e...

Wiki-based collaborative content creation enables new communication practices and thereby challenges several assumptions of existing media ch...
Conference Paper
Estimating is difficult. This is true whether the task requires forecasting uncertain future events, or whether the estimation task is complex in itself and based on insufficient information. As a result, even perceived experts frequently estimate poorly. Surprisingly, recent research suggests that groups of non-experts can outperform individual ex...
Conference Paper
Traditionally, analysis of flow fields resulting from computational fluid dynamics (CFD) calculations is a sequential process. The flow area defined by surrounding geometry is tessellated, a mesh is generated and divided into subregions, transferred to a cluster or supercomputer and the result is transferred back. Then, a variety of post-processing...
Article
Geometrical modeling is a crucial aspect of simulations involving manufactured objects and is usually performed using free-form surfaces. However, to simulate the flow through or about a manufactured object or to simulate structural integrity, the free-form surfaces must be tessellated into triangulated surfaces.
