Writing treatment that involved repeated copying and recall of target words was implemented with 8 individuals with severe aphasia in order to discern the best candidates for the treatment. Four of the 8 participants had strong positive responses to the copy and recall treatment (CART), relearning spellings for 15 targeted words during 10 to 12 weeks of treatment and up to 5 additional words du...

OBJECTIVE Alcohol-dependent patients in early abstinence show an impairment of cognitive functions which can be seen in poor implementation of newly learned skills for avoiding relapse. Executive dysfunction may persist during abstinence in alcohol-dependent persons, thus mitigating long-term abstinence. This study assessed visual memory function and choice of organizational strategies in alcoh...

We tested a hypothesis originating with Darwin that bees outside the nest exhibit social learning in flower choices. Naive bumblebees, Bombus impatiens, were allowed to observe trained bees or artificial bees forage from orange or green flowers. Subsequently, observers of bees on green flowers landed more often on green flowers than non-observing controls or observers of models on orange flower...

We introduce a new replication-based copying garbage collection technique. We have implemented one simple variation of this method to provide incremental garbage collection on stock hardware with no special operating system or virtual memory support. The performance of the prototype implementation is excellent: major garbage collection pauses are completely eliminated with only a slight increas...

We formally and empirically examine the phonological relation immediate precedence, its properties, and further relations that can be derived from it. When each occurrence of a phonological segment in a nonlinear multiprecedence structure is reconcatenated into a linear sequence of copies, reduplication results (Raimy 2000a). A number of consequences arise in the representation of affixes, in m...

An analytical approach to network dynamics is used to show that when agents copy their state randomly the network arrives to a stationary regime in which the distribution of states is independent of the degree. The effects of network topology on the process are characterized introducing a quantity called influence and studying its behavior for scale-free and random networks. We show that for th...

Exchanging mutable data objects with untrusted code is a delicate matter because of the risk of creating a data space that is accessible by an attacker. Consequently, secure programming guidelines for Java stress the importance of using defensive copying before accepting or handing out references to an internal mutable object. However, implementation of a copy method (like clone()) is entirely ...

The SLG-WAM can be characterized as a sharing approach to implementing tabling: the execution environments of suspended computations are intersperced in the WAM stacks. Stacks are frozen using a set of freeze registers and the WAM trail mechanism is extended so that the suspended computations can be resumed. This technique has a reasonably small execution overhead, but is not easy to implement ...
