Estadounidenses And Gringos As Reality And Imagination In Mexican Narrative Of The Late Twentieth Century, Jessica Lynam

Dissertations

The representation of North Americans in contemporary Mexican narrative texts is frequent, complex and worthy of study. The present dissertation makes no pretense of being a comprehensive catalogue of “gringos” in Mexican narrative; it can be better seen as a cross-section of Mexican literature concerning people from the United States published during the final two decades of the twentieth century. My intention is to explore how this Mexican narrative has characterized non-Mexican Americans and contextualize these visions in terms of their cultural and historical origins. In this study I analyze six texts authored by both men and women, border authors …

High School Mathematics Teachers' Evolving Understanding Of Comparing Distributions, Sandra R. Madden

Dissertations

Statistics has achieved a position of status in the secondary curriculum (College Board, 2006b; Franklin et al., 2007; NCTM, 2000) and understanding of statistics is essential for high school mathematics teachers if they are to engage students in thoughtful pursuit of statistical ideas. High school teachers typically are ill-prepared in the area of statistics (Ben-Zvi & Garfield, 2004a; CBMS, 2001; Shaughnessy, 1992, 2007). Using methods of design research, this study investigated 56 high school mathematics teachers' understanding of the statistical concept ofcomparing distributions and demonstrated that a modest four-day, statistics-oriented, technology-rich, professional development program may significantly improve teachers' understanding. …

Radiographic And Functional Analysis Of Movement Allowed By Four Wrist Immobilization Devices, Timothy M. Mullen

Dissertations

Immobilization of the wrist is a common practice throughout the healthcare industry. The main forms of wrist immobilization are short-arm casts, prefabricated wrist splints, custom volar wrist splints, and custom circumferential wrist splints. It is generally accepted, by the medical community, that each form of immobilization allows for some movement. The amount each device allows is unknown. Establishing data that accurately describe the amount of mobility in each immobilization device will allow clinicians to make an evidence-based decision each time they are confronted with the need to order an orthosis.

The purpose of this study was to identify the specific …

Construction Of A New Model System In Saccharomyces Cerevisa To Study Yopo And Identify Its Targets, Laura Nejedlik

Dissertations

Yersinia species use a type three secretion system (TTSS) to inject Yersinia outer proteins (Yops) into the target cell. The effector YopO is a serine/threonine kinase which upon association with actin becomes active. However, activation of the kinase is not required for actin disruption. YopO also contains a Rho/Rac binding domain, but it is unclear how it affects these proteins.

We have established an expression system in Saccharomyces cerevisiae to study YopO. The expression vector contains a GAL1 promoter for inducible expression of YopO as well as a V5 epitope used for visualization of each Yop. We have shown that …

Generalization effects across settings were assessed using a typical Social Story (Train and Hope) format and …

Coincidence Theory: Seeking A Perceptual Preference For Just Intonation, Equal Temperament, And Pythagorean Intonation In Excerpts For Wind Instruments, Derle Ray Long

Dissertations

Coincidence theory states that when the components of harmony are in enhanced alignment the sound will be more consonant to the human auditory system. An objective method of examining the components of harmony is by investigating alignment of the mathematics of a particular sound or harmony. The study examined preference responses to excerpts tuned in just intonation, Pythagorean intonation, and equal temperament. Musical excerpts were presented in pairs and study subjects simply picked one version from the pair that they perceived as the most consonant. Results of the study revealed an overall preference for equal temperament in contradiction to coincidence …

The Role Of Msa In The Global Regulation Of Virulence In Staphylococcus Aureus, Vijayaraj Nagarajan

A Comparison Of Reading Interventions Based On Preference To Reading Interventions Identified By Brief Experimental Analysis, Debborah Eda Smyth

Dissertations

The available literature on children's acceptability of interventions is rather sparse and offers little support for the link between acceptability and effectiveness (e.g., Foxx & Jones, 1978; Shapiro & Goldberg, 1986; Turco & Elliot, 1990). The present study compared the effects of treatment preference to treatment effectiveness using a brief experimental analysis to select skill-based oral reading fluency interventions. The use of a brief experimental analysis (BEA) (Daly, Martens, Hamler, Dool, & Eckert, 1999) has been demonstrated to be an effective procedure for selecting oral reading interventions. However, the studies on brief experimental analysis to date have not examined student …
