Permissions allowed or denied at the property level apply only to specific properties. For example, you can set a property-level permission on a User object that allows a particular user, such as Principal Self (that is, the user represented by the object), to change the Home Address property of the User object.

The American Psychiatric Association published the first version of the DSM in 1952. It has been revised several times, and the newest version is commonly referred to as the DSM-IV.
Published by the American Psychiatric Association (APA), the Diagnostic and Statistical Manual of Mental Disorders (DSM) is used to diagnose mental and behavioral conditions. The fifth edition, the DSM-5, will be released on May 18, 2013 and announced at the annual meeting of the APA.
