Expectation-confirmation theory (ECT) posits that satisfaction is determined by interplay of prior expectations and perception of delivery. As such, there are many applications in research and practice that employ an ECT model. The descriptive power allows independent investigations manipulating either of the components and a format to examine just why clients are satisfied (or not) with a part...

Computational complexity began with the natural physical notions of time and space Given a property S an important issue is the computational complexity of checking whether or not an input satis es S For a long time the notion of complexity referred to the time or space used in the compu tation A mathematician might ask What is the complexity of expressing the property S It should not be surpri...

Given the recent and highly publicized scandals involving psychology researchers who cheated, the proliferation of articles on related topics is unsurprising. As an example, Simons et al. (2011) pointed out subtle ways in which researchers can increase their false positive rate above the nominal level of p < 0.05. From my perspective, a major limitation of the literature on cheating has been a ...

Definition 1.1. Let (X, τ) be a topological space. A subset D ⊆ X is called dense if D ∩O 6= ∅ for every nonempty open set O ⊆ X. X is called separable if X has a countable dense subset. X is called metrizable if there is a metric d on X such that the topology τ is the same as the topology induced by the metric. The metric is called complete if every Cauchy sequence converges in X. Finally, X i...

Electronic markets and especially online auctions gain more and more importance and a plethora of market mechanisms is emerging on the Internet. The great variety of trading rules hinders agents easily switching between different marketplaces and, therefore, fragments the overall market – supply and demand might fail to meet due to agents’ inability to interact with the same market mechanism. T...
