  1. Route dependence

    the route dependence on initial velocity . For an object moving between two positions, route dependence may apply not just to the spatial path but also to the spacetime path taken. These arguments ...Expert subject Physics date February 2009 In theoretical physics , the issue of route dependence deals with whether a selected differential between two points is taken as Wiktionary absolute absolute , or as being partly a function of the route along which comparative measurements are taken. It usually applies in discussions of gravitational potential or related effects such as gravitational redshift . In simpler exercises in gravitational physics, it is common to invoke gravitational potential as an absolute difference between two positions that does not depend on the route, and to invoke energy conservation as a reason why the energy gained or lost when an object moves between two defined states is fixed, independent of the route taken. In more advanced gravitational theory, things are not so straightforward the nominal gravitational potential between two positions often has to be supplemented with route dependent effects, or defined in a route dependent manner. Spatial route dependence If we place two observers A and B on opposite sides of a rotating black hole, both on the rotation plane, with the hole directly between them, and with both observers being the same height above the hole, then the effective gravitational differential between the A and B measured across the plane depends on the direction around the hole in which measurements are taken. If light signals are exchanged around one side of the hole, in the equatorial plane, where the adjacent section of event horizon is moving roughly in the direction A B , then frame dragging effects should make it easier for light to move with the horizon s motion than against it, and the measurements should show B to be downhill ... descriptions, but the underlying physics itself is paradox free.

  1. Psychological dependence

    In the APA Dictionary of Psychology, psychological dependence is defined as dependence on a psychoactive substance for the reinforcement it provides. ref VandenBos, Gary R.

They are similar in that addiction is a physiological craving for something and psychological dependence is a need for a particular substance because it causes enjoyable mental affects. A person becomes dependent on something, usually drugs, to help alleviate specific emotions. ref name APA Dictionary Myers, David G. Psychology . 9th ed. New York Worth, 2010. Print. ref Psychological dependence begins after the first trial which a person then becomes satisfied and the satisfaction increases with each use. This constant feeling leads to psychological reinforcement which eventually leads to dependence. ref Hanson, Glen, Peter J. Venturelli, and Annette E. Fleckenstein. Drugs and Society.

Print. ref Of the various things that a person can be psychologically dependent on, opiates, benzodiazepines, barbiturates, alcohol, and nicotine are among the top substances people become dependent on.

  1. Dependence analysis

    In compiler theory , dependence analysis produces execution order constraints between statements instructions. Broadly speaking, a statement S2 depends on S1 if S1 must be executed before S2 . Broadly, there are two classes of dependencies control dependencies and Data dependency data dependencies . Dependence analysis determines whether or not it is safe to reorder or parallelize statements. Control dependencies A situation in which a program s instruction executes if the previous instruction evaluates in a way that allows its execution. A statement S2 is control dependent on S1 written math S1 delta c S2 math if and only if S2 s execution is conditionally guarded by S1 . The following is an example of such a control dependence S1 if x 2 goto L1 S2 y 3 S3 L1 z y 1 Here, S2 only runs if the predicate in S1 is false.

  1. Menu dependence

    Roughly speaking, in decision theory , game theory , and rational choice , menu dependence arises when the evaluation of alternatives for choice or the mode of selection guiding choice varies parametrically with what collection of alternatives is available for choice i.e., with what menu or decision problem a decision maker is facing . Menu dependence can be accompanied by violations of various so called consistency or coherence constraints, such as Sen s condition also known as Chernoff s Axiom, a contraction condition and Sen s conditions and expansion conditions . While the phenomenon can arise in a variety of ways, menu dependence is often informally associated with a change in a decision maker s preferences among alternatives with the addition of irrelevant alternative s.

It was originally published in Japanese in 1971, and an English translation by John Bester was later published in 1973. The book describes at length Doi s concept of amae , which he describes as a uniquely Japanese need to be in good favor with, and be able to depend on, the people around oneself. He likens this to behaving childishly in the assumption that parents will indulge you Doi 2001 16 , and claims that the ideal relationship is that of the parent child, and all other relationships should strive for this degree of closeness Doi 2001 39 .

The so called subscales of reward dependence in TCI R are Sentimentality RD1 Openness to warm communication RD2 Attachment RD3 Dependence RD4 C.
