Preliminary Selection and Characterization of Pseudo-Invariant Calibration Sites in Northwest China

Remote Sensing, 2020
Pseudo-invariant calibration sites (PICS) have been used for the radiometric calibration and stability monitoring of satellite optical sensors. Several stable PICS, such as those in the Sahara Desert in North Africa, were selected for the vicarious ...

Once Validated, Always Validated? [PDF]

The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2007
YOU need a brief measure, say, of stress, or social resources, or functional status. You find one that not only seems to address the conceptual issues about which you are concerned, but for which information on validity and reliability have also been published. Moreover, it has been used frequently, and its name is well recognized.
