Privacy regulations can affect the willingness to collect personal health data that may be disclosed to insurers. Perfect privacy cannot always be guaranteed. Consequently, people may refrain from collecting personal health data. This paper provides a theoretical and experimental analysis of the importance of privacy regulations for information acquisition and disclosure behavior. We contrast t...
The purpose of this project is to develop methods for organizing and collecting information about trail networks for future use in a Tourism Information System. Some questions that are answered concern how to organize and structure the basic information as well as the location based data so that it can be processed, stored and presented in digital format. The practical work has resulted in an e...
Federally sponsored health surveys are a critical source of information on public health in the United States. The National Center for Health Statistics (NCHS) is the nation's principal health statistics agency and is responsible for collecting accurate, relevant, and timely data. NCHS conducts several population-based national surveys as well as collecting vital statistics data, which are used...
This paper examines approaches to representing uncertainty in reputation systems for electronic markets with the aim of constructing a decision theoretic framework for collecting information about selling agents and making purchase decisions in the context of a social reputation system. A selection of approaches to representing reputation using Dempster-Shafter Theory and Bayesian probability a...

The use of Floating Car Data (FCD) systems for the generation of traffic information has been discussed in numerous publications, many of which are based on simulated data or on a small number of vehicles collecting data over a limited time span. We present FLEET, a real-world FCD system, which has been continuously operating since 2003, collecting data from thousands of taxis in the Vienna reg...
This article reports a content analysis of the privacy policy statements (PPSs) from 97 general reference health Web sites that was conducted to examine the ways in which visitors' privacy is constructed by health organizations. PPSs are formal documents created by the Web site owner to describe how information regarding site visitors and their behavior is collected and used. The results show t...
We consider the classical coupon collector’s problem in which each new coupon collected is type i with probability pi; P i1⁄41 n pi1⁄41. We derive some formulas concerning N, the number of coupons needed to have a complete set of at least one of each type, that are computationally useful when n is not too large. We also present efficient simulation procedures for determining P(N . k), as well a...
Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...
Computational Grids are distributed systems that provide access to computational resources in a transparent fashion. Collecting and providing information about the status of the Grid itself is called
