Dorn (German for thorn) is a German/Austrian and Dutch/Flemish surname. Notable people with the surname include:
Dorn is a diceless tactical fantasy board game developed in Czech Republic and published by Altar in 2006.
One or more players control a group of heroes and one player controls the evil Dornkeeper and his monsters. The heroes need to collect three artifacts from the game board and then they can challenge the Dornkeeper himself. As there is no dice in combat, the game is based on strategy and tactics, when heroes need to cooperate in order to win.
There are nine heroes to choose from, each having unique abilities on three experience levels. The Dornkeeper has eight different types of monsters at his disposal. Treasure cards found on the gameboard as well as random Blessing cards make every game quite different, there is no ultimate winning strategy.
In November 2009, the first expansion became available, with the title "Eternal Return of the Koschei", featuring new heroes, monsters and an immortal Dornkeeper.
The game was originally published in Czech, but is now available in English (including the first expansion).
Dorn is a German black metal band.
It was founded as a solo project in 1998 by Roberto Liebig, the ex-keyboardist of pagan metal band Riger. Dorn's 2000 debut album Falschheit was recorded in the studios of CCP Records in Linz, with Liebig playing all of the instruments himself.
The album received good reviews, so Liebig was signed by CCP Records and left his role in Riger. Falschheit was followed by Brennende Kälte in 2001 and Schatten der Vergangenheit in 2002. For the 2004 album Suriel, Liebig was joined by Michael Werber, Sebastian Ziem, Lars, and Ira. With this lineup, Dorn toured in Germany, but in 2005 Lars and Ira left the band. In October 2006, Liebig and the other two remaining band members recorded the album Spiegel der Unendlichkeit, which was released on February 23, 2007.
Aggression is overt, often harmful, social interaction with the intention of inflicting damage or other unpleasantness upon another individual. It may occur either in retaliation or without provocation. In humans, frustration due to blocked goals can cause aggression. Submissiveness may be viewed as the opposite of aggressiveness.
In definitions commonly used in the social sciences and behavioral sciences, aggression is a response by an individual that delivers something unpleasant to another person. Some definitions include that the individual must intend to harm another person.Predatory or defensive behavior between members of different species may not be considered aggression in the same sense.
Aggression can take a variety of forms, which may be expressed physically, or communicated verbally or non-verbally: including anti-predator aggression, defensive aggression (fear-induced), predatory aggression, dominance aggression, inter-male aggression, resident-intruder aggression, maternal aggression, species-specific aggression, sex-related aggression, territorial aggression, isolation-induced aggression, irritable aggression, and brain-stimulation-induced aggression (hypothalamus). There are two subtypes of human aggression: (1) controlled-instrumental subtype (purposeful or goal-oriented); and (2) reactive-impulsive subtype (often elicits uncontrollable actions that are inappropriate or undesirable). Aggression differs from what is commonly called assertiveness, although the terms are often used interchangeably among laypeople (as in phrases such as "an aggressive salesperson").
A war of aggression, sometimes also war of conquest, is a military conflict waged without the justification of self-defense, usually for territorial gain and subjugation. The phrase is distinctly modern and diametrically opposed to the prior legal international standard of "might makes right", under the medieval and pre-historic beliefs of right of conquest. Since the Korean War of the early 1950s, waging such a war of aggression is a crime under the customary international law. Possibly the first trial for waging aggressive war is that of the Sicilian king Conradin in 1268.
Wars without international legality (e.g. not out of self-defense nor sanctioned by the United Nations Security Council) can be considered wars of aggression; however, this alone usually does not constitute the definition of a war of aggression; certain wars may be unlawful but not aggressive (a war to settle a boundary dispute where the initiator has a reasonable claim, and limited aims, is one example).
In the game of poker, opens and raises are considered aggressive plays, while calls and checks are considered passive (though a check-raise would be considered a very aggressive play). It is said that "aggression has its own value", meaning that often aggressive plays can make money with weak hands because of bluff value. In general, opponents must respond to aggressive play by playing more loosely, which offers more opportunities to make mistakes.
While it is true that aggressive play is generally superior to passive play, using any play exclusively can lead to predictability. A player who is constantly aggressive and plays many inferior hands is called a "maniac", and skilled players will take advantage of him by calling him more often, using isolation plays, and by other means.
If a player is not aggressive with his weaker hands, the opponents can safely fold whenever the player does bet or raise. The appropriate amount of aggression can be computed using game theory, and depends on the game being played and the tendencies of the opponents.
