A national survey of the arrangements managed-care plans make with physicians.
BACKGROUND Despite the growth of managed care in the United States, there is little information about the arrangements managed-care plans make with physicians. METHODS In 1994 we surveyed by telephone 138 managed-care plans that were selected from 20 metropolitan areas nationwide. Of the 108 plans that responded, 29 were group-model or staff-model health maintenance organizations (HMOs), 50 w...
متن کاملAnalyzing Data Management Plans: Where Librarians Can Make a Differ- ence
Since January 18, 2011, any researcher applying to a National Science Foundation (NSF) grant must include a data management plan (DMP) in their proposal. Many librarians have responded to this mandate by establishing new datarelated services. One potential area for engaging with researchers in the grant proposal process is offering a DMP review service. In preparation for offering a DMP review...
متن کاملIntermodal blocking in honeybees.
Previous findings of intramodal but not of intermodal blocking in foraging honeybees prompted a new series of experiments with colours, odours, a proximal visual landmark, and a localized geomagnetic anomaly as stimuli. In Experiments 1-2, the landmark was blocked by both colour and odour. In Experiments 3-6, the anomaly was blocked by both colour and odour, but the anomaly failed to block eith...
متن کاملMite not make it home: tracheal mites reduce the safety margin for oxygen delivery of flying honeybees.
Many physiological systems appear to have safety margins, with excess capacity relative to normal functional needs, but the significance of such excess capacity remains controversial. In this study, we investigate the effects of parasitic tracheal mites (Acarapis woodi) on the safety margin for oxygen delivery and flight performance of honeybees. Tracheal mites did not affect the flight metabol...
متن کاملReward expectations in honeybees.
The study of expectations of reward helps to understand rules controlling goal-directed behavior as well as decision making and planning. I shall review a series of recent studies focusing on how the food gathering behavior of honeybees depends upon reward expectations. These studies document that free-flying honeybees develop long-term expectations of reward and use them to regulate their inve...
