Branching Time and Abstraction in Bisimulation Semantics
- JOURNAL OF THE ACM
, 1996
"... In comparative concurrency semantics, one usually distinguishes between linear time and branching time semantic equivalences. Milner’s notion of ohsen~ation equirlalence is often mentioned as the standard example of a branching time equivalence. In this paper we investigate whether observation equi ..."

actions) and the usual laws for strong congruence. WC also establish that for sequential processes observation equivalence is not preserved under refinement of actions, whereas branching bisimulation is. For a large class of processes, it turns out that branching bisimulation and observation equivalence
The two-parameter Poisson-Dirichlet distribution derived from a stable subordinator.
, 1995
"... The two-parameter Poisson-Dirichlet distribution, denoted pd(ff; `), is a distribution on the set of decreasing positive sequences with sum 1. The usual Poisson-Dirichlet distribution with a single parameter `, introduced by Kingman, is pd(0; `). Known properties of pd(0; `), including the Markov ..."

Asymmetric tournament, equal opportunity laws, and affirmative action: Some experiment results
- Quarterly Journal of Economics
, 1992
"... This paper assesses whether affirmative action programs and equal opportu-nity laws affect the output of economic agents. More precisely, we find that equal opportunity laws and affirmative action programs always benefit disadvantaged groups. Equal opportunity laws also increase the effort levels of ..."

A Causal Theory of Ramifications and Qualifications
, 1995
"... This paper is concerned with the problem of determining the indirect effects or ramifications of actions. We argue that the standard framework in which background knowledge is given in the form of state constraints is inadequate and that background knowledge should instead be given in the form of &q ..."

of "causal laws." We represent "causal laws" first as inference rules and later as sentences in a modal, conditional logic C flat . For the framework with "causal laws," we propose a simple fixpoint condition defining the possible next states after performing an action
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

91 Although these theories provide important insights into reward function, they tend to neglect the fact that individuals usually operate in a world with limited nutritional and mating resources, and that most resources occur with different degrees of uncertainty. The animal in the wild
Equivalence in Functional Languages with Effects
, 1991
"... Traditionally the view has been that direct expression of control and store mechanisms and clear mathematical semantics are incompatible requirements. This paper shows that adding objects with memory to the call-by-value lambda calculus results in a language with a rich equational theory, satisfying ..."

, satisfying many of the usual laws. Combined with other recent work this provides evidence that expressive, mathematically clean programming languages are indeed possible. 1. Overview Real programs have effects---creating new structures, examining and modifying existing structures, altering flow of control
Stable Laws and Domains of Attraction in Free Probability Theory

"... In this paper we determine the distributional behavior of sums of free (in the sense of Voiculescu) identically distributed, infinitesimal random variables. The theory is shown to parallel the classical theory of independent random variables, though the limit laws are usually quite di#erent. Our wor ..."

This decision has been further complicated by the implementation of Regulation FD by the SEC that requires that the company make material market moving information available to all investors at the same time.

There is no contradiction between the assertion that compulsory attendance has had little effect on the number of children attending
