The design of the interface for e-commerce transactions is one source of influence that can affect an online shopper’s trust in the merchant. This paper undertook a confirmatory factor analysis involving 14 trust-inducing interface design features that populated a conceptual framework proposed in our previous study. The factor analysis of self-reported ratings of the features, which were illust...

In a recent issue of Critical Care, Qiao and colleagues showed in a rat model of sepsis that dexmedetomidine and midazolam suppress the generation of pro-inflammatory mediators but the effects vary between agents. While dexmedetomidine limited apoptosis to a greater extent than midazolam, both agents significantly reduced short-term mortality compared with saline. This study, in addition to tho...

Antiarrhythmic drugs Types. A variety of antiarrhythmic drugs are available, both conventional and investigational. They can be divided into groups: those that exert blocking actions predominantly on sodium, potassium, or calcium channels, and those that block /3-adrenergic receptors. Exensive subclassification' of these drugs does not seem to be useful, primarily because it does not help in ch...

User-centric systems call for novel methods and tools for a tight and implicit man machine interaction. Often highly personalized system are sensitive and reactive to user psychological, social and physical situation. However providing such a support may cross the barriers of our privacy or may have impacts on us that we do not necessarily agree upon.

In this paper we study the operation of incremental data extraction from declarative knowledge bases and the problem of decomposability of data in such KBs, by viewing them as first-order logical theories. The operation of incremental data extraction is closely connected with query reformulation in information retrieval and data integration, while the decomposability problem is important in the...

We study a market model in which competing firms use costly marketing devices to influence the set of alternatives which consumers perceive as relevant. Consumers in our model are boundedly rational in the sense that they have an imperfect perception of what is relevant to their decision problem. They apply well-defined preferences to a “consideration set”, which is a function of the marketing ...
