Data breaches represents a major source of worries (and economic losses) for customers and service providers. We introduce a data breach model that recognizes that breaches can take place on the customer’s premises as well as on the service provider’s side, but the customer bears the economic loss. In order to induce the service provider into investing in security, a regulatory policy that appo...

We study the pricing and capacity allocation problem of a service provider who serves two distinct customer classes. Customers within each class are inherently heterogeneous in their willingness to pay for service, but their utilities are also affected by the presence of other customers in the system. Specifically, customer utilities depend on how many customers are in the system at the time of...

Group Support Systems enable harvesting knowledge from groups. The minutes of a typical GSS meeting are mostly textual reports of 10 to 50 pages summarizing the issues discussed, the set priorities and proposed actions. Capitalizing on knowledge generated during GSS meetings appears to be very difficult without additional automated support. In this paper we describe our experiences with several...

Little is known about the use of services in a preferred provider organization (PPO). We studied a preferred provider arrangement between Pacific Medical Center and employees of the City of Seattle. In the second 12 months of this program 8,529 subjects submitted at least one claim; of these, only 420 (4.9%) ever used the preferred provider. Those who used the PPO at least once differed signifi...

The paper presents a new online service for the dependency parsing of Polish. Given raw text as input, the service processes it and visualises output dependency trees. The service applies the parsing system – MaltParser – with a parsing model for Polish trained on the Polish Dependency Bank, and some additional publicly available tools.

We examine the effect of an anomalous flavor changing chromomagnetic moment which allows direct top quark production (two partons combining into an unaccompanied single top quark in the schannel) at hadron colliders. We consider both t-c-g and t-u-g couplings. We find that the anomalous charm quark coupling parameter κc/Λ can be measured down to .06 TeV (.009 TeV) at the Tevatron with the Main ...

BACKGROUND Among indigenous populations in remote locations who are at increased risk for chronic diseases such as diabetes, telemedicine has the potential to improve access to health care services and thus may reduce adverse health outcomes. Yet few studies are available on how best to use telemedicine technology in reducing ethnic and racial health care disparities. OBJECTIVE We examined pe...
