Implicit and explicit measures: a test of a dissociative model of aggression
This study tested a dissociative model of aggression measurement. Aggression is construed as having two components, each of which is associated more strongly with either implicit or explicit measures of aggression. A videogame based frustration manipulation was used to elicit hostile aggressive responses in the form of hard force applied to buttons. Instrumental aggression criteria were also assessed in the form of honesty in reporting game outcomes, willingness to pause games while believing that pausing could damage the study results, and willingness to use unfair strategies that are also described as damaging to study results. Differential prediction of these behaviors by implicit and explicit measures of aggression supported a dissociative model of aggression measurement.M.S.Committee Chair: Dr. Lawrence R.

Using Management Techniques to Solve Environmental Problems
Arguing that little effective progress is being made in solving problems of varying urgency, this paper suggests a leadership role for science and engineering societies. It proposes that such societies attempt to prioritize problems and attempt to focus public awareness (and calls to action) in a more systematic way
From Frequency to Meaning: Vector Space Models of Semantics
Computers understand very little of the meaning of human language. This
profoundly limits our ability to give instructions to computers, the ability of
computers to explain their actions to us, and the ability of computers to
analyse and process text. Vector space models (VSMs) of semantics are beginning
to address these limits. This paper surveys the use of VSMs for semantic
processing of text. We organize the literature on VSMs according to the
structure of the matrix in a VSM. There are currently three broad classes of
VSMs, based on term-document, word-context, and pair-pattern matrices, yielding
three classes of applications. We survey a broad range of applications in these
three categories and we take a detailed look at a specific open source project
in each category. Our goal in this survey is to show the breadth of
applications of VSMs for semantics, to provide a new perspective on VSMs for
those who are already familiar with the area, and to provide pointers into the
literature for those who are less familiar with the field
Involutory quandles of (2,2,r)-Montesinos links
In this paper we show that Montesinos links of the form L(1/2, 1/2, p/q;e),
which we call (2,2,r)-Montesinos links, have finite involutory quandles. This
generalizes an observation of Winker regarding the (2, 2, q)-pretzel links. We
also describe some properties of these quandles.Comment: 19 pages, 8 figure
Twisted Alexander polynomials of 2-bridge knots
We investigate the twisted Alexander polynomial of a 2-bridge knot associated
to a Fox coloring. For several families of 2-bridge knots, including but not
limited to, torus knots and genus-one knots, we derive formulae for these
twisted Alexander polynomials. We use these formulae to confirm a conjecture of
Hirasawa and Murasugi for these knots.Comment: 29 pages, 2 figure
PCLIPS
CLIPS is an expert system, created specifically to allow rapid implementation of an expert system. CLIPS is written in C, and thus needs a very small amount of memory to run. Parallel CLIPS (PCLIPS) is an extension to CLIPS which is intended to be used in situations where a group of expert systems are expected to run simultaneously and occasionally communicate with each other on an integrated network. PCLIPS is a coarse-grained data distribution system. Its main goal is to take information in one knowledge base and distribute it to other knowledge bases so that all the executing expert systems are able to use that knowledge to solve their disparate problems
