A multispectral-sensor-based colorimetric reader for biological assays.

Tests that depend on changes in color are commonly used in biosensing. Here, we report on a colorimetric reader for such applications. The device is simple to construct and operate, making it ideal for research laboratories with limited resources or skilled personnel.

Learning in Crisis: Training students to monitor and address irresponsible knowledge construction by U.S. federal agencies under Trump.

Evaluation of an MMPI--a short form: implications for adaptive testing.

Efforts to develop a viable short form of the MMPI (Hathaway & McKinley, 1943) span more than 50 years, with more recent attempts to significantly shorten the item pool focused on the use of adaptive computerized test administration. In this article, we report some psychometric properties of an MMPI-Adolescent version (MMPI-A; Butcher et al., 1992) short form based on administration of the first 150 items of this test instrument.
