It can be argued that much of the evidence generated in the United States on the importance of early childhood to future health and attainment has had a greater effect on the national policies of other countries than it has in the U.S., which lacks a national policy agenda for young children. However, the U.S. is not the only country to struggle with the direction early childhood policy should ...
We present new experimental constraints on the WIMP-nucleon spin-dependent elastic cross sections using data from the first science run of ZEPLIN-III, a two-phase xenon experiment searching for galactic dark matter weakly interacting massive particles based at the Boulby mine. Analysis of approximately 450 kg x days fiducial exposure allow us to place a 90%-confidence upper limit on the pure WI...
This study aims to advance understanding of Internet interactions by considering the impact of Web site design and self-monitoring style on consumer preference. Four quasi-commercial Web sites were constructed containing identical information presented via a context-based (animated) or content-based (unanimated) design, and 2 advertisements of either imageor information-oriented style. Using a ...
The coincidence site lattice (CSL) problem and its generalization to Z-modules in Euclidean 3-space is revisited, and various results and conjectures are proved in a unified way, by using maximal orders in quaternion algebras of class number 1 over real algebraic number fields.
The explosive increase in Internet accessibility and use offers unique opportunities for providing health information to adolescents via the Internet. The purpose of this evaluation study was to explore the opinions of adolescents regarding an Internet-based health monitoring instrument and its individually tailored electronic feedback so that recommendations for improvement can be provided. A ...

Like traditional media, information on the World Wide Web may encourage both healthy and unhealthy behaviors. This study reports on the content analysis of a particular genre of Web site that promotes unhealthy behaviors: pro-eating disorder Web sites. Framed in message design theory, the results of this study indicate that messages on pro-eating disorder Web sites promote response efficacy in ...

The analysis of Sudan dyes has gained considerable attention during last years. In several publications multiple peaks in chromatograms of Sudan III and Sudan IV have been detected. It is demonstrated in this work that if the sample is kept in darkness before analysis, only one chromatographic peak appears for Sudan III or Sudan IV. In normal lighting conditions two peaks are observed. This lig...
