TL;DR: In this article, a self-report measure of posttraumatic stress disorder (PTSD), the Posttraumatic Diagnostic Scale (PTDS), was developed and validated for screening and assessing current PTSD in clinical and research settings.
Abstract: The present article reports on the development and validation of a self-report measure of posttraumatic stress disorder (PTSD), the Posttraumatic Diagnostic Scale (PTDS), that yields both a PTSD diagnosis according to Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994; DSM-IV) criteria and a measure of PTSD symptom severity. Two-hundred forty-eight participants who had experienced a wide variety of traumas (e.g., accident, fire, natural disaster, assault, combat) were administered the PTSD module of the Structured Clinical Interview (SCID; Spitzer, Williams, Gibbons, & First, 1990), the PTDS, and scales measuring trauma-related psychopathology. The PTDS demonstrated high internal consistency and test-retest reliability, high diagnostic agreement with SCID, and good sensitivity and specificity. The satisfactory validity of the PTDS was further supported by its high correlations with other measures of trauma-related psychopathology. Therefore, the PTDS appears to be a useful tool for screening and assessing current PTSD in clinical and research settings.

TL;DR: In this article, a measure of manipulability of robotic mechanisms in positioning and orienting end-effectors has been proposed and the best postures of various types of manipulators are given, and a four degree-of-freedom finger is considered from the viewpoint of the measure.
Abstract: This paper discusses the manipulating ability of robotic mechanisms in positioning and orienting end-effectors and proposes a measure of manipulability. Some properties of this measure are obtained, the best postures of various types of manipulators are given, and a four-degree-of-freedom finger is considered from the viewpoint of the measure. The pos tures somewhat resemble those of human arms and fingers.
