Description:
This paper presents a study of PH, a woman with aphasia, who shows a robust impairment in naming pictures of non-living relative to living things. Un-timed investigations of feature knowledge show similar performance across categories suggesting that, as in previous studies, the category effect may be arising at a post-semantic level. However, her performance on a timed feature verification task was slower for non-living than living things (relative to matched controls), in line with her naming. This suggests that the source of PH's category deficit is in fact semantic and that thorough investigation is necessary before claiming a post-semantic category specific deficit in word production. Finally, the results of an intervention study, which apparently eliminated the effect of semantic category on PH's naming, are reported.

A Unifying Framework for Structured Analysis and Design Models: An Approach Using Initial Algebra Semantics and Category Theory (Cambridge Tracts in Theoretical Computer Science)
$27.99
Structured methodologies are a popular and powerful tool in information systems development. Many different ones exist, each employing a number of models and so a specification must be converted from one form to another during the development process. To solve this problem, Dr. Tse proposes a unifying framework behind popular structured models. He approaches the problem from the viewpoints of algebra and category theory. He not only develops the frameworks but also illustrates their practical and theoretical usefulness. Thus, this book will provide insight for software engineers into how methodologies can be formalized, and will open up a range of applications and problems for theoretical computer scientists.

Stochastic Coalgebraic Logic (Monographs in Theoretical Computer Science. An EATCS Series)
$99.00
Coalgebraic logic is an important research topic in the areas of concurrency theory, semantics, transition systems and modal logics. It provides a general approach to modeling systems, allowing us to apply important results from coalgebras, universal algebra and category theory in novel ways. Stochastic systems provide important tools for systems modeling, and recent work shows that categorical reasoning may lead to new insights, previously not available in a purely probabilistic setting. This book combines coalgebraic reasoning, stochastic systems and logics. It provides an insight into the principles of coalgebraic logic from a categorical point of view, and applies these systems to interpretations of stochastic coalgebraic logics, which include well-known modal logics and continuous time branching logics. The author introduces stochastic systems together with their probabilistic and categorical foundations and gives a comprehensive discussion of the Giry monad as the underlying categorical construction, presenting many new, hitherto unpublished results. He discusses modal logics, introduces their probabilistic interpretations, and then proceeds to an analysis of Kripke models for coalgebraic logics. The book will be of interest to researchers in theoretical computer science, logic and category theory.

Functional Categories and Parametric Variation (Theoretical Linguistics)
$155.00
Functional Categories and Parametric Variation is an attempt to make sense of the idea that functional categories are the ``flesh and blood of grammar.'' From within the context of the Principles and Parameters framework put forward by Chomsky and others, Jamal Ouhalla develops the argument that much of what we understand by the term grammar
