Conversational Repair Strategies Of Preschool Children During Naturalistic Interactions, Richard J. Stott

Theses and Dissertations

Within the area of pragmatics, the subject of children's repair strategies has been an issue of considerable research for many years. Most of this research has not addressed verbal and nonverbal repair strategy behaviors particularly among preschool children enrolled in an integrated preschool program. The purpose of the present study was to describe how preschool children enrolled in an integrated preschool program request clarification in naturalistic situations and how they use conversational repair strategies following a stacked sequence of requests for clarification by adults.

Naturalistic inquiry was used to establish an inventory of strategies used by handicapped and non-handicapped children …

The Interactive Effects Of Caffeine And Estrogen On Memory For Word Lists, Mary Ellen Arnold

Theses and Dissertations

Previous research has yielded conflicting results regarding the effects of caffeine on word list recall. Erikson et al. (1985) found that caffeine impaired recall among females when words were presented at a slow rate. Arnold et al. (1988) observed a facilitory effect of caffeine on the recall, after practice, of females tested during Days 1-5 of the menstrual cycle. Research on cognitive task performance among females suggests that performance varies according to the phase of menstrual cycle. Medical research demonstrates a relationship between estrogen and caffeine metabolism. In this study, it was hypothesized that females' recall of word lists would …

Many questions are discussed: how to sub-divide and list the Zapotec languages and dialects; what data format will be most accessible to researchers as well as to field workers with data to add; computer software considerations (designing computational tools); how to handle non-cognates with shared meanings, non-overlap of glosses (i.e., one Zapotec gloss covers several Spanish words, or vice versa), semantic shifts and secondary meanings, and other problems such as special characters, free variation, elisions, etc.; whether to …

Esther's Narrative In Bleak House, Jennifer Willa Tonn Sternhagen

Theses and Dissertations

This thesis explores the complexity of Dickens's involvement with his narrative and characters, specifically Esther Summerson in the novel Bleak House. The introduction examines his habit of interrupting the speech of his characters with direct authorial comments in order that he not give up his story entirely to a character, even in an extended first-person narration. It is noted that this is true even of characters who are autobiographical, like Pip or David Copperfield. Here my references are to the work of Susan R. Horton (The Reader in the Dickens World) and Mark Lambert (Dickens and the Suspended Quotation).

The Effects Of Alcohol On Semantic Memory, Norman A. Kerbel

Theses and Dissertations

Previous studies have shown that the effects of alcoholic intoxication on memory result from a functional decrease in capacity of working memory (e.g., Petros, Kerbel, Beckwith, Sacks, & Sarafolean, 1985). However, other studies looking at speeds of retrieval of information from long-term memory have brought this conclusion into doubt (Moskowitz & Roth, 1971). The present study presented subjects with decisions to be made regarding word pairs. Three conditions were used, each requiring different amounts of information to be accessed from long-term memory.

Sixty-six male college students, between the ages of 21 and 29 years, were divided into two groups. One …

The Effects Of Viewing Aggressive Family Discord On The Spatial Perception Of A Home Environment., John David Collins

Theses and Dissertations

The intent of this study was to examine the effects of viewing domestic discord on cognitive mapping in a home-like environment. Subjects' level of arousal was manipulated by having them watch a videotape containing scenes of domestic violence before they completed a cognitive mapping task in a furnished, two-bedroom apartment. In an attempt to prolong the effect of videotape content, subjects were exposed to white noise while they completed the cognitive mapping task. The inclusion of control conditions, along with the two arousal factors (videotape content and noise), resulted in four experimental groups.Forty female subjects watched one of the videotapes …

Aesthetic Field Theory., Murali C. Ramanathan

Theses and Dissertations

A smooth (1:2) tensor field A on a finite dimensional Banach space E is used to define a derivation, called the A-derivative and analogous to the covariant derivative of General Relativity, on the algebra of smooth tensor fields on E. The A-derivative is only an $\IR$-multilinear map into the ring C(E) of all smooth $\IR$-valued functions on E and thus the field equation, which is simply the requirement that the A-derivative of A vanish, is thus covariant under automorphisms of the base space E. The curvature and torsion tensors of the A-derivation are defined once again by analogy to the …

An In Vitro Analysis Of Melanoma Cell Attachment To Isolated Glomerular Basement Membranes., Ronald K. Jyring

Theses and Dissertations

Penetration of blood vessel basement membranes (BMs) by metastatic cells apparently proceeds by a three step process involving attachment, degradation, and migration. In the current study, isolated glomerular BMs (GBMs) were used as model substrates for studying cell attachment to BMs.Murine and bovine gomeruli were isolated by differential sieving of homogenized renal tissues. GBMs were prepared by treating glomeruli with detergents and enzymes. This was facilitated by using "sieving chambers" which prevented tissue loss during the detergent extraction procedure. The ultrastructure of detergent isolated murine and bovine GBMs was similar to other species, although they had a greater tendency to …

The Michif Technique: Code-Switch Cue, Carol Starzer Wildeman

Theses and Dissertations

The Michif technique is a method of language modification which encourages code-switching by introducing a third language as a cue. The method targets syntax modification and does not apply to phonetic modification.

The technique derives its name from the Michif Language which is the cue language used in the study. The learning of Michif is not a long-range goal of this study, but rather through the use of Michif code-switching can be fun and nonthreatening.

The Michif technique follows the bidialectical view which encourages the use of code-switching in formal environments and the use of the vernacular while in informal …

The Phenomenon Of Superconductivity: A Feasibility Study For Business, Julian E. Thrash

Theses and Dissertations

Why should American industries risk future viability in order to invest in superconductivity? This independent study explored this question in order to reach a more informed conclusion. The tendency for American firms is to plan for short-term profits at the expense of research and development programs. By cutting research and development funds, firms are losing a proprietary knowledge base necessary to compete in a dynamic environment. A loss of proprietary knowledge in the field of science, severely handicaps a firm in its drive for success.

The information presented in this study is an attempt to give the average corporate executive …
