It is concluded that the product of hedonic glands is a sulfated mucin that is discharged in response to cholinergic stimulation of muscarinic receptors in myoepithelial cells. Since hedonic glands, but not mucous glands, from breeding newts of both sexes incorporated 35SO 4 into their product, bands from hedonic glands could be distinguished from those of mucous glands in gels. A smaller but similar band from hedonic glands of breeding females correlated with one of the two. Two PAS (+) bands were present in polyacrylamide gels prepared from secretions discharged by hedonic glands after treatment of male newts in breeding conformation with pilocarpine HCL and also in gels from skin samples containing mucous glands, but were absent from hedonic secretions of laboratory conditioned males. Preincubation in the muscarinic blocking agent atropine sulfate, but not in nicotinic blocking agent d-tubocurarine chloride, prevented the cholinergic response. Mean luminal diameters of hedonic glands in explants incubated in solutions of acetyl choline decreased by 58% of control values while those of explants incubated in solutions of epinephrine remained the same. Endings of unmyelinated axons, containing both clear and dense-cored synaptic vesicles, were seen to lie between the myoepithelium and the secretory epithelium, occasionally touching on the myoepithelial cells. The ultrastructure of the myoepithelium has been studied. Hedonic coalition nets represent hedonic games through weighted Boolean formulas.The mechanism whereby secretory product is extruded from the lumina of hedonic glands in the red-spotted newt has been investigated and the chemical nature of that product has been examined.Note that if there are only polynomially many individually rational coalitions, then this representation only takes polynomial space. For many solution concepts, it is irrelevant how precisely the player ranks unacceptable coalitions, since no stable coalition structure can contain a coalition that is not individually rational for one of the players. 4 Concise representations and restricted preferencesįormally, a hedonic game is a pair ( N, ( ≽ i ) i ∈ N ).Hedonic games are studied both in economics, where the focus lies on identifying sufficient conditions for the existence of stable outcomes, and in multi-agent systems, where the focus lies on identifying concise representations of hedonic games and on the computational complexity of finding stable outcomes. The players in hedonic games are typically understood to be self-interested, and thus hedonic games are usually analyzed in terms of the stability of coalition structures, where several notions of stability are used, including the core and Nash stability. the ethical doctrine that regards pleasure and happiness as the highest good. Some well-known subclasses of hedonic games are given by matching problems, such as the stable marriage, stable roommates, and the hospital/residents problems. 90 of all salamanders utilize spermatophores for internal fertilization. Thus, in contrast to other cooperative games, a coalition does not choose how to allocate profit among its members, and it does not choose a particular action to play. skin slightly rougher and caudal fins become longer hedonic glands in male. Their distinguishing feature (the "hedonic aspect" ) is that players only care about the identity of the players in their coalition, but do not care about how the remaining players are partitioned, and do not care about anything other than which players are in their coalition. Hedonic games are a type of non-transferable utility game. Such partitions are often referred to as coalition structures. The outcome of a hedonic game consists of a partition of the players into disjoint coalitions, that is, each player is assigned a unique group. A hedonic game is specified by giving a finite set of players, and, for each player, a preference ranking over all coalitions (subsets) of players that the player belongs to. In cooperative game theory, a hedonic game (also known as a hedonic coalition formation game) is a game that models the formation of coalitions (groups) of players when players have preferences over which group they belong to.
