What causes bird-building collision risk? Seasonal dynamics and weather drivers.

Bird-building collisions are a major source of wild bird mortality, with hundreds of millions of fatalities each year in the United States and Canada alone. Here, we use two decades of daily citizen science monitoring to characterize day-to-day variation in building collisions and determine the factors that predict the highest risk times in two North American cities. We use these analyses to evaluate three potential causes of increased collision risk: heightened migration traffic during benign weather, increased navigational and flight errors during inclement weather, and increased errors in response to highly directional sunlight that enhances reflected images.

The Development and Evaluation of an Electronic Health Record Efficiency Workshop for Providers.

Background: The electronic health record (EHR) has historically been known to be a source of stress and dissatisfaction, leading to reduced efficiency and productivity for providers. This issue is complicated by constant changes in EHRs that are necessary to keep systems current with evolving functionality. Knowing the existence of this problem, an evidenced-based solution, known as an efficiency workshop, was developed by our information technology training and optimization team for providers as a means of ongoing professional development.

Spatiotemporal distributions of reported cases of the avian influenza H5N1 (bird flu) in Southern China in early 2004.

This study investigates spatiotemporal distributions of reported cases of the avian influenza H5N1 (bird flu) in Southern China in early 2004. Forty-nine cases of the avian influenza H5N1 covering a 6-week period (January 19, 2004, through March 9, 2004) were compiled from the Chinese Ministry of Agriculture and the World Health Organization. Geographic information systems (GIS) techniques combined with statistical techniques were used to analyze the spatiotemporal variation of reported cases of avian influenza.

Hplc/electrospray ionization mass spectrometric analysis of the heterocyclic aromatic amine carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine in human milk.

A new procedure has been developed for the extraction of 2-amino-1-methyl-6-phenyl-imidazo[4,5-b]pyridine (PhIP) and other heterocyclic aromatic amines from human breast milk samples. Extracts were analyzed by high-performance liquid chromatography/electrospray ionization/tandem mass spectrometry (HPLC/ESI-MS/MS) with selective reaction monitoring detection. Tandem ESI-MS/MS detection provides much improved sensitivity and specificity, compared with those of a previous method that used selected ion monitoring.
