THE McGILL PAIN QUESTIONNAIRE
The problem of pain, since the beginning of this century, has been dominated by the concept that pain is purely a sensory experience. Yet it has a unique, distinctively unpleasant, affective quality that differentiates it from sensory experiences such as sight, hearing or touch. . . . The motivational-affective dimension of pain is brought clearly into focus by clinical studies on frontal lobot...
متن کاملMagnetar Spin-Down.
We examine the effects of a relativistic wind on the spin-down of a neutron star and apply our results to the study of soft gamma repeaters (SGRs), which are thought to be neutron stars with magnetic fields greater than 1014 G. We derive a spin-down formula that includes torques from both dipole radiation and episodic or continuous particle winds. We find that if SGR 1806-20 puts out a continuo...
متن کاملTriggers of magnetar outbursts
Bright outbursts from Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are believed to be caused by instabilities in ultramagnetized neutron stars, powered by a decaying magnetic field. It was originally thought that these outbursts were due to reconnection instabilities in the magnetosphere, reached via slow evolution of magnetic footpoints anchored in the crust. Later models con...
متن کاملExciting the Magnetosphere of the Magnetar
We describe XMM-Newton observations taken 4.3 days prior to and 1.5 days subsequent to two remarkable events that were detected with Swift on 2006 September 21 from the candidate magnetar CXOU J164710.2-455216: (1) a 20 ms burst with an energy of 10 erg (15–150 keV), and (2) a rapid spin-down (glitch) with ∆P/P ∼ −10. We find that the luminosity of the pulsar increased by a factor of 100 in the...
متن کاملTeaching the Radical Catalog
During a recent information literacy session for a group of first-year students enrolled in an African-American women's history course at Sarah Lawrence College, I discussed the changing Library of Congress (LC) subject headings for this field: NEGRO WOMEN; BLACK WOMEN; AFRICAN-AMERICAN WOMEN; etc. A student raised her hand and asked whether students specifically interested in the history of Wh...
