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 DSM. Psychologists and psychiatrists use a reference book called the Diagnostic and Statistical Manual of Mental Disorders (DSM) to diagnose psychological disorders. 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.
The Diagnostic and Statistical Manual of Mental Disorders, or DSM for short, is a text that provides the requirements to diagnose a mental disorder, along with statistics and suggested course of treatment for different psychological disorders. The DSM has gone through many revisions, and the most current version is the DSM-5. Think of it like a cookbook, except instead of looking for a recipe, you are eating something and trying to figure out what it is.
