This thesis describes a generative model for representing disfluent phenomena in human speech. This model makes use of observed syntactic structure present in disfluent speech, and uses a right-corner transform on syntax trees to model this structure in a very natural way. Specifically, the phenomenon of speech repair is modeled by explicitly…

Many within the field of educational systems design believe that in order for the ideal system to exist, where all stakeholders benefit, the users of the system must be involved in its design and implementation. This requires the users to engage in dialogue. First, however, more overall involvement is necessary in order to bring these stakeholders…

This dissertation presents a novel method of sentence generation, drawing on the insight from Cognitive Semantics (Talmy, 2000a,b) that the effect of uttering a sentence is to evoke a Cognitive Representation in the mind of the listener. Under the assumption that this Cognitive Representation is also present in the speaker and defines (part of)…

This study examines the facilitative effects of embodiment of a complex internal anatomical structure through three-dimensional ("3-D") interactivity in a virtual reality ("VR") program. Since Shepard and Metzler's influential 1971 study, it has been known that 3-D objects (e.g., multiple-armed cube or external body parts) are visually and…

This dissertation investigates and explores the best method for the delivery of graduate student services. Essentially, there are two methods for delivery of these services. They can be delivered by virtue of centralization or decentralization. Decentralized delivery, for the purpose of this dissertation is the delivery of graduate student…

This study investigated two major sources of influence (institution and individual characteristics) on the earnings of graduate degree recipients. These factors have been shown in previous research to influence the initial earnings of graduates at the undergraduate level. This research seeks to build on previous studies by Perna (2003, 2005) that…

The variety and complexity of potentially-related data resources available for querying--webpages, databases, data warehouses--has been growing ever more rapidly. There is a growing need to pose integrative queries "across" multiple such sources, exploiting foreign keys and other means of interlinking data to merge information from diverse…

The increasing demand for nontraditional courses acknowledges that individuals are not monolithic in their approach to learning. The uniqueness of an individual's learning preferences is often due to their experiences. Although individuals tend to have a primary learning preference, they may choose to employ an array of learning styles based on…
