In many theme parks, stores are located within major attractions to sell related merchandise. Sales at such stores form a significant portion of theme park profits. Typically, store sales depend upon visitor flows through the attraction, customer satisfaction with the attraction, and the merchandise at the store. In addition, such stores constitute a unique retail environment, as visitor flows ...

Polyphosphoinositides are among the most highly charged molecules in the cell membrane, and the most common polyphosphoinositide, phosphatidylinositol-4,5-bisphosphate (PIP(2)), is involved in many mechanical and biochemical processes in the cell membrane. Divalent cations such as calcium can cause clustering of the polyanionic PIP(2), but the origin and strength of the effective attractions le...

W. J. Eckert [1] has adapted Cowell's method of numerical integration to the determination of orbits on punched card machines. Eckert, Brouwer, and Clémence [2] have used Cowell's method on a large-scale computer. We shall assume that Cowell's method as modified by Eckert is the method of numerical integration best suited for the determination of orbits on large-scale computers. What we are con...

In this paper, we present the participation of the University of Amsterdam’s ExPoSe team in the TREC 2016 Contextual Suggestion Track. The main goal of contextual suggestion track is to evaluate methods for providing suggestions for activities or points of interest to users in a specific location, at a specific time, taking their personal preferences into consideration. One of the key steps of ...

Despite the economic significance of the theme park industry and the huge investments needed to set up new attractions, no marketing models exist to guide these investment decisions. This study addresses this gap in the literature by estimating a response model for theme park attendance. The model not only determines the contribution of each attraction to attendance, but also how this contribut...

We describe a general model, `experience-weighted attraction' (EWA) learning, which includes reinforcement learning and a class of weighted ctitious play belief models as special cases. In EWA, strategies have attractions which re ect prior predispositions, are updated based on payo experience, and determine choice probabilities according to some rule (e.g., logit). A key feature is a parameter...

Adaptive learning models that have been tested against experimental data typically share two features: (i) initial attractions (or beliefs) are given exogenously, and (ii) learning is based on the performance of stage-game actions rather than repeated game strategies. We develop a model of learning which endogenizes initial attractions and allows for the learning of repeated game strategies. Le...
