Safe and appropriate health care, especially in urgent or emergency situations, is the expectation of the public throughout the developed world. Achieving this goal requires appropriate levels of medical and other staff, appropriate training, and sensible working hours. Too often the brunt of such care, especially in out-of-hours situations, is borne by medical residents, who--to make matters w...

We investigated the extent to which the safety performance (i.e., self-reported safety compliance and safety participation) of employees with 2 jobs was predicted by their respective supervisors' transformational leadership behaviors. We compared 2 within-person models: a context-specific model (i.e., transformational leadership experienced by employees in 1 context related to those same employ...

Recent decennial censuses and the American Community Survey (ACS) collect data that permit construction of average hourly wage rates. However, reports concerning usual hours worked during the past year contain errors that create incredible implied wages for part-time workers.

The effect of a single (% LDs0) dose (65 mg/kg body weight) of pyrrolizidine alkaloid isolated from Senecio jacobaea on liver microsome mixed function oxidase activity in rats was studied. Within 1 hr of dosing, there was a decline (P<.05) in the pyrrole production rate in vitro from pyrrolizidine alkaloid. At 24 hr, there was reduced (P<.01) activity of aminopyrine N-demethylase, and cytochrom...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...

Free-electron lasers (FEL) hold the potential to revolutionize structural biology by producing X-ray pules short enough to outrun radiation damage, thus allowing imaging of biological samples without the limitation from radiation damage. Thus, a major part of the scientific case for the first FELs was three-dimensional (3D) reconstruction of non-crystalline biological objects. In a recent publi...

BACKGROUND The pharmacokinetics and pharmacodynamics of medications may differ between children and adults, necessitating different dose regimens for different age groups. Levocetirizine, the active enantiomer of cetirizine, is used in the treatment of allergic rhinitis and chronic urticaria in Europe. Its pharmacokinetics and pharmacodynamics have not yet been studied prospectively in school-a...

RESTART is an accelerated simulation technique that allows the evaluation of extremely low probabilities. In this method a number of simulation retrials are performed when the process enters regions of the state space where the chance of occurrence of the rare event is higher. These regions are defined by means of a function of the system state called the importance function. Guidelines for obt...

A conceptual program to use NLC beams for test beams and fixed target physics is described. Primary undisrupted polarized beams would be the most simple to use, but for NLC, the disrupted beams are of good enough quality that they could also be used, after collimation of the low energy tails, for test beams and fixed target physics. Pertinent issues are: what is the compelling physics, what are...
