To obtain estimates for the prevalence of Toxoplasma gondii infection in ducks and geese in Germany, enzyme-linked immunosorbent assays (ELISA) were established based on affinity-purified T. gondii tachyzoite surface antigen 1 (TgSAG1) and used to examine duck and goose sera for T. gondii-specific antibodies. The results of 186 sera from 60 non-infected ducks (Anas platyrhynchos) and 101 sera from...
In this paper we explore the idea that ratings systems, common across successful e-commerce sites, can better engage individuals in online learning networks.

Our research measures the impact this system had on five graduate courses over the course of two...
This paper examines the impact of cyberinfrastructure architecture on healthcare services. More specifically, this research details the architectural design for a personal health record system called "HealthATM" that utilizes and integrates services from Google's cloud computing environment. These services are integrated into an unobtrusive and easy to use ATM-style interface for health...
