Aggression
Some scholars believe that behaviors like aggression may be partially learned by watching and imitating people's behavior, while other researchers have concluded that the media may have some small effects on aggression. There is also research questioning this view. For instance, a long-term outcome study of youth found no long-term relationship between playing violent video games and youth violence or bullying. One study suggested there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively associated to time spent playing the games. The author concluded that insufficient evidence exists to link video game violence with aggression. However, another study suggested links to aggressive behavior.
Passive-aggressive behavior
Passive-aggressive behavior from workers and managers is damaging to team unity and productivity. In the ad for Warner's online ebook, it says: "The worst case of passive-aggressive behavior involves destructive attitudes such as negativity, sullenness, resentment, procrastination, 'forgetting' to do something, chronic lateness, and intentional inefficiency." If this behavior is ignored it could result in decreased office efficiency and frustration among workers. If managers are passive-aggressive in their behavior, it can end up stifling team creativity. De Angelis says, "It would actually make perfect sense that those promoted to leadership positions might often be those who on the surface appear to be agreeable, diplomatic and supportive, yet who are actually dishonest, backstabbing saboteurs behind the scenes."
