scipline or interdisciplinary area and show how it might relate to transgender studies. While far from providing a complete picture of the field, these keywords begin to elucidate a conceptual vocabulary for transgender studies. Some of the submissions offer a deep and resilient resistance to the entire project of mapping the field terminologically; some reveal yet-unrealized critical potentials for the field; some take existing terms from canonical thinkers and develop the significance for transgender studies; some offer overviews of well-known methodologies and demonstrate their applicability within transgender studies; some suggest how transgender issues play out in various fields; and some map the productive tensions between trans studies and other interdisciplines.1f:T44e,Diagnostic Criteria From DSM-IV,by the American Psychiatric Association, 358 pp, spiral-bound, $22.50, ISBN 0-89042-064-5, Washington, DC, American Psychiatric Press Inc, 1994.

First, Ruth Ross, and Wendy Davis, 768 pp, $112.50, ISBN 0-89042-065-3, Washington, DC, American Psychiatric Association, 1994. DSM-IV: Diagnostic and Statistical Manual of Mental Disorders, fourth edition, was developed with a great deal of input from mental health professionals and professional organizations. In addition, there was a significant collaboration between the American Psychiatric Association (APA) and the World Health Organization, as it developed the tenth revision of theInternational Statistical Classification of Diseases and Related Health Problems (ICD-10). As a result, DSM-IV is a great improvement over the third edition(DSM-III)and the third edition, revised(DSM-III-R). The Task Force onDSM-IVand 13 work groups (each responsible for a section20:T435,Preventing or delaying the onset of physical frailty is an increasingly important goal because more individuals are living well into their 8th and 9th decades. We describe the development and validation of a functional fitness test battery that can assess the physiologic parameters that support physical mobility in older adults. The procedures involved in the test development were (a) developing a theoretical framework for the test items, (b) establishing an advisory panel of experts, (c) determining test selection criteria, (d) selecting the test items, and (e) establishing test reliability and validity. The complete battery consists of 6 items (and one alternative) designed to assess the physiologic parameters associated with independent functioning—lower and upper body strength, aerobic endurance, lower and upper body flexibility, and agility/dynamic balance. We also assessed body mass index as an estimate of body composition. We concluded that the tests met the established criteria for scientific rigor and feasibility for use in common community settings.
