Purpose – Facilitating knowledge sharing within organisations is a difficult task: the willingness of individuals to share and integrate their knowledge is one of the central barriers. This paper aims to develop a motivation-based perspective to explore how organisations resolve the social dilemma of knowledge sharing. Design/methodology/approach – The analysis builds on a three-category taxono...

Anhedonia, defined as the state of reduced ability to experience feelings of pleasure, is one of the hallmarks of depression. Hedonic tone is the trait underlying one's characteristic ability to feel pleasure. Low hedonic tone represents a reduced capacity to experience pleasure, thus increasing the likelihood of experiencing anhedonia. Low hedonic tone has been associated with several psychopa...

In this paper, a statistically optimal solution to the Perspective-n-Point (PnP) problem is presented. Many solutions to the PnP problem are geometrically optimal, but do not consider the uncertainties of the observations. In addition, it would be desirable to have an internal estimation of the accuracy of the estimated rotation and translation parameters of the camera pose. Thus, we propose a ...

Despite offering several promising concepts, the Language/Action Perspective (LAP) is still not in the mainstream of Information Systems Development (ISD). Since at present there is only a limited understanding of LAP theory and practice, it remains unclear whether the lack of LAP’s impact is due to shortcomings in LAP theory itself. One classic problem within ISD is the dichotomy between socia...

eSports services are situated between cooperation distinctive for many hedonic activities and competition relevant to the creation of hedonic behavior. This raises the challenge for eSports providers to offer services that fulfill consumers' needs. Against this background, we apply Uses and Gratifications theory (Rayburn and Palmgreen, 1984) and investigate which competitive and hedonic need gr...

Despite the widespread adoption of smartphone applications, empirical research that examines the user acceptance on different application types is still scare. This paper empirically compares the effects of perceived enjoyment and perceived risk on hedonic and utilitarian smartphone applications. Our analyses show that perceived enjoyment is a stronger determinant of intention to use a hedonic ...

Hedonic games are coalition formation games in which players have preferences over the coalitions they can join. All models of representing hedonic games studied so far are based upon selfish players only. Among the known ways of representing hedonic games compactly, we focus on friend-oriented hedonic games and propose a novel model for them that takes into account not only a player’s own pref...

There has recently been a dramatic increase in the number of papers that have combined quasi-experimental methods with hedonic property models. This is largely due to the concern that cross-sectional hedonic methods may be severely biased by omitted variables. While the empirical literature has developed extensively, there has not been a consistent treatment of the theory and methods of combini...

Poor executive function (EF; pre-frontal cognitive control processes governing goal-directed behavior) and elevated hedonic hunger (i.e., preoccupation with palatable foods in the absence of physiological hunger) are theoretical risk and maintenance factors for binge eating (BE) distinct from general obesity. Recent theoretical models posit that dysregulated behavior such as BE may result from ...

Because it is harder to justify hedonic purchases than utilitarian purchases, it is proposed that promotions will have a stronger positive effect on the purchase likelihood of hedonic than utilitarian products. This and related propositions are tested in multiple studies using a variety of product categories and promotions. The results demonstrate that promotions are more effective in driving p...
