Content Analysis Of University Alcohol Policies: "Party Schools" Compared To Non-Party Schools, Sarah E. Pernie

Dissertations

Universities across the United States are dealing with an alarming number of underage students drinking on or near campus. One prevention tool is having a comprehensive alcohol usage policy for students, which includes content as recommended by a number of national organizations focused on decreasing underage drinking on campuses. Yet little is known about the content actually contained in current university alcohol policies.

To this end, my research involved a content analysis of the alcohol policies from 71 purposefully selected universities across the country. These included institutions identified as "party schools" by the Princeton Review , and a similar sample …


Research Self-Efficacy And Research Mentoring Experiences As Predictors Of Occupational Commitment In Counselor Education Doctoral Students, Glinda Jeanette Rawls Dec 2008

Research Self-Efficacy And Research Mentoring Experiences As Predictors Of Occupational Commitment In Counselor Education Doctoral Students, Glinda Jeanette Rawls

Dissertations

The demands of research and pressure to publish have been identified as reasons doctoral graduates in counselor education infrequently choose faculty careers (Maples, Altekruse, & Testa, 1993; Swickert, 1997). Despite this finding, the counselor education literature provides very little information on doctoral students' research self-efficacy or perceived ability to complete research-related tasks (Bieschke, Bishop, & Herbert, 1995). In addition, research mentoring can enhance research self-efficacy (Hollingsworth & Fassinger, 2002), yet it too remains understudied. Research mentoring involves someone more experienced promoting research skill, awareness, and productivity to someone less experienced (Dohm & Cummings, 2002). Few studies have explored research self-efficacy, …

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 Dec 2008

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 Dec 2008

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 …


Modeling Fluid Structure Interaction Over A Flexible Fin Attached To A Naca0012 Airfoil, Srinivasa Ravindra Pantula Dec 2008

Modeling Fluid Structure Interaction Over A Flexible Fin Attached To A Naca0012 Airfoil, Srinivasa Ravindra Pantula

Dissertations

Flow separation control is of importance to the performance of air vehicles. Generally, it is desired to postpone separation such that the overall drag is reduced, stall is delayed, lift is enhanced, and pressure recovery is improved. This work explores a new concept of post-stall flow control for airfoils and wings by using a thin flexible fin attached on the upper surface of an airfoil to passively manipulate flow structures in the fully separated flows for drag reduction and lift enhancement. The flow induced oscillations combined with the shape deformations change the overall pressure distribution on the fin, which in …

Construction Of A New Model System In Saccharomyces Cerevisa To Study Yopo And Identify Its Targets, Laura Nejedlik Dec 2008

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 …

Characterization Of The Ap-1 And Nf-Kappa B Transcription Factors In The U-87 Mg Astrocytoma Cell Line, Denise L. Smith Dec 2008

Characterization Of The Ap-1 And Nf-Kappa B Transcription Factors In The U-87 Mg Astrocytoma Cell Line, Denise L. Smith

Dissertations

Growth factors, signaling molecules and transcription factors are frequently mutated in cancer and platelet-derived growth factor (PDGF) has been shown to be over-expressed in most gliomas. In the astrocytoma cell line U-87 MG, the over-expression of PDGF has been shown to lead to over-expression of transcription factors activator-protein-1 (AP-1) and nuclear factor-kappa B (NF-κB), and it is believed that the individual subunits of AP-1 (c-Jun, JunB, JunD, c-Fos, FosB, Fra-1, and Fra-2) and NF-κB (c-Rel, p50, p52, p65, and RelB) play different roles in proliferation, survival and differentiation in the U-87 MG cell line.

To assess these different roles, transient …
