Moilanen's (1995) study of adolescent depression also attempts to validate Beck's theory in a new way, as Beck worked mostly with adults. Indeed, she found that the student's depression was often associated with dysfunctional beliefs and negative future attitudes.
A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class.
To put it simply, a hash tag is simply a way for people to search for tweets that have a common topic and to begin a conversation. For example, if you search on #LOST (or #Lost or #lost, because it's not case-sensitive), you'll get a list of tweets related to the TV show.
