The perceived inability of behaviorism to deal with complex human behavior has been a recurrent theme among its critics. Although ingenious and subtle, even Skinner's Verbal Behavior (1957) is widely faulted on these grounds, in particular, for failing to explain linguistic generativity (Chomsky, 1959). In Relational Frame Theory: A PostSkinnerian Account of Human Language and Cognition, Hayes,...

There are two major problems with current designs for VBR service a it is inherently hard to compactly and completely describe VBR tra c sources and b sustained peaks in the source rate substan tially degrade the performance We propose a new scheme Renegoti ated CBR RCBR that augments CBR service with fast renegotiation and bu er monitoring Analysis shows that the scheme is easily imple mentabl...

We report that electron-capture supernovae (ECSNe), arising from collapsing oxygen-neonmagnesium cores, are a possible source of Ca, whose origin has remained a long-standing puzzle. Our two-dimensional, self-consistent explosion model of an ECSN predicts ejection of neutron-rich matter with electron fractions Ye ≈ 0.40–0.42 and relatively low entropies, s ≈ 13–15 kB per nucleon (kB is the Bolt...

Atomistic simulations have become a powerful tool in materials research due to the extremely fine spatial and temporal resolution provided by such techniques. To understand the fundamental principles that govern material behavior at the atomic scale and directly connect to experimental works, it is necessary to quantify the microstructure of materials simulated with atomistics. Specifically, qu...

We establish a lower bound of 2 conditional branches for deciding the satisfiability of the conjunction of any two Boolean formulas from a set called a full representation of Boolean functions of n variables a set containing a Boolean formula to represent each Boolean function of n variables. The contradiction proof first assumes that there exists a Post machine (Post’s Formulation 1) that corr...

ABSTRACT Coordination is an important issue in multi-agent systems. A possible approa h to ta kle oordination, that re ently reeived quite a lot of attention, is to learn the e e ts of intera tion in the joint a tion spa e. However joint a tion spa es violate generally a epted requirements of multi-agents systems, su h as : distributed ontrol, asyn hronous a tions, in omplete information, ost o...

BACKGROUND & AIMS Patients with severe Alzheimer's disease (AD) in long-term care have deficient contrast sensitivity and poor food and liquid intake. The present study examined how contrast manipulations affect these intake levels. METHODS Participants were nine men with advanced AD. Independent variables were meal type (lunch and supper) and condition (baseline, intervention, and post-inter...

The objective of this theoretical article is to describe a conceptual framework for research on effects of past and current abuse and posttraumatic stress on childbearing women. The proposed framework builds on an earlier framework proposed by the Centers for Disease Control and Prevention (CDC) for research on violence occurring around the time of pregnancy. Two main adaptations are suggested....
