Estimating Diet And Food Selectivity Of The Lower Keys Marsh Rabbit Using Stable Isotope Analysis, Matthew James Gordon

Electronic Theses and Dissertations

Understanding the effect of food abundance on feeding behavior can benefit conservation efforts in many ways, such as to determine whether impacted environments need food supplementation, whether different locations of threatened species contain different food abundances, or whether reintroduction sites are missing key components of a species’ diet. I studied the relationship between feeding behavior and food abundance in the Lower Keys marsh rabbit (Sylvilagus palustris hefneri), an endangered subspecies endemic to the lower Florida Keys. Specifically, my study set out to measure the relative abundance of the primary plants within the natural habitat of the Lower Keys marsh rabbit …

Evaluation Of A Simulation-Enhanced Obstetric Clinical Experience On Learning Outcomes For Knowledge, Self-Efficacy, And Transfer, Mary Elizabeth Guimond

Electronic Theses and Dissertations

Simulation using computerized patient mannequins may be a useful mechanism to teach safe and effective nursing care, thus improving the quality of education for nurses. As nursing program enrollments grow, clinical placement is becoming more difficult and may not offer consistent learning opportunities that reinforce safe and effective nursing practice. This study applied Ford, Smith, Weissbein, Gully, and Salas’ (1998) model of learning transfer as the theoretical framework to design a simulated obstetric clinical learning experience to augment the current clinical practice model, an approach that may lead to an improved educational experience. The purpose of this study was to …

Social Comparison, Self-Objectification, And Objectification Of Others Investigating The Vicious Cycle That Leads To Body Dissatisfaction And Disordered Eating, Danielle M. Lindner

Electronic Theses and Dissertations

The purpose of this study was to test a new theoretical model that integrates self-objectification, objectification of others, and social comparison as contributors to the development and maintenance of body image disturbance and disordered eating behavior. Within the new theoretical model, self-objectification, objectification of others, and social comparison are conceptualized as a self-perpetuating cycle, rather than as processes that occur independently of one another. Four hundred fifty-nine female college students between the ages of 18 and 32 completed measures of self-objectification, objectification of others, social comparison, body shame, body dissatisfaction, and eating disorder symptomatology. Structural equation modeling with nested model …

Increasing Self Reported Argumentativeness In College Level Public Speaking Students, Kim E. Long

Electronic Theses and Dissertations

Argumentativeness, or the predisposition “to advocate positions on controversial issues and to attack verbally the positions which other people take on these issues” (Infante & Rancer, 1982, p.72), has been associated with a number of positive outcomes. Research among student populations indicates that compared to people who are low in argumentativeness, people high in argumentativeness display higher ability to learn, higher self esteem, greater ability to creatively manage conflict, and higher ability to see both sides of a situation (Barden & Petty, 2008; McPherson Frantz & Seburn, 2003; Rancer, Whitecap, Kosberg, & Avtgis, 1997). Promoting argumentativeness among college students should …

Dialectical Tensions Between Glocalization And Grobalization For Wal-Mart In The United States, Laura Lord

Electronic Theses and Dissertations

This qualitative analysis examines Wal-Mart managers‟ perspectives of the strategies that the U.S. corporation has implemented in order to increase its sales and profits at more than 4,000 stores in local U.S. communities. Two theoretical paradigms are specifically used: glocalization and grobalization. The former refers to cultural adaptation; the latter means standardization. The ultimate goal of the researcher is to identify the dialectical tensions between those two current forms of globalization. In-depth, face-to-face, qualitative interviewing of ten Wal-Mart managers in Central Florida allowed the researcher to actually comprehend managers‟ perspectives, gather fresh data, and construct a final product to enlighten …

The Communication Implications And Related Experiences Associated With Transracially Adopting A Child From Vietnam, Lan Marie Malin

Electronic Theses and Dissertations

This study investigated the communication experiences of adoptive parents of children transracially adopted from Vietnam. Though adoption has been extensively studied in communication research, transracial adoptions involving children from Vietnam has not. Thus, this study examined adoptive parent communication experiences using dialectic theory and relational dialectics. By examining adoptive parents’ communication with their adopted child and others, we can determine tensions that occur in different communication experiences. Data were collected through eight qualitative in-depth interviews conducted with adoptive parents of children from Vietnam. Openness with both strangers and the adopted child(ren) and preservation of key aspects of the adopted children’s …

Survey Of Meteorite Physical Properties Density, Porosity And Magnetic Susceptibility, Robert J. Macke

Electronic Theses and Dissertations

The measurement of meteorite physical properties (i.e. density, porosity, magnetic susceptibility) supplements detailed chemical and isotopic analyses for small samples (thin sections or ~300 mg portions) by providing whole-rock data for samples massing in the tens of grams. With the advent of fast, non-destructive and non-contaminating measurement techniques including helium ideal-gas pycnometry for grain density, the Archimedean ―glass bead‖ method for bulk density and (with grain density) porosity, and the use of low-field magnetometry for magnetic susceptibility, all of which rely on compact and portable equipment, this has enabled a comprehensive survey of these physical properties for a wide variety …

A Wearable Head-Mounted Projection Display, Ricardo F. Martins

Electronic Theses and Dissertations

Conventional head-mounted projection displays (HMPDs) contain of a pair of miniature projection lenses, beamsplitters, and miniature displays mounted on the helmet, as well as a retro-reflective screen placed strategically in the environment. We have extened the HMPD technology integrating the screen into a fully mobile embodiment. Some initial efforts of demonstrating this technology has been captured followed by an investigation of the diffraction effects versus image degradation caused by integrating the retro-reflective screen within the HMPD. The key contribution of this research is the conception and development of a mobileHMPD (M-HMPD). We have included an extensive analysis of macro- and …

Transplantation Of Ips Cells Reduces Apoptosis And Fibrosis And Improves Cardiac Function In Streptozotocin-Induced Diabetic Rats, Sarah Elizabeth Neel

Electronic Theses and Dissertations

Background: Streptozotocin (STZ) induced diabetes leads to various complications including cardiomyopathy. Recent data suggests transplanted bone marrow stem cells improve cardiac function in diabetic cardiomyopathy. However, whether modified ES, iPS cells, or factors released from these cells can inhibit apoptosis and fibrosis remains completely unknown. The present study was designed to determine the effects of transplanted ES cells overexpressing pancreatic transcription factor 1 a (Ptf1a), a propancreatic endodermal transcription factor, iPS cells, or their respective conditioned media (CM) on diabetic cardiomyopathy. Methods: Experimental diabetes was induced in male Sprague Dawley rats (8-10 weeks old) by intraperitoneal STZ injections (65 mg/kg …

Initial-Value Technique For Singularly Perturbed Two Point Boundary Value Problems Via Cubic Spline, Luis G. Negron

Electronic Theses and Dissertations

A recent method for solving singular perturbation problems is examined. It is designed for the applied mathematician or engineer who needs a convenient, useful tool that requires little preparation and can be readily implemented using little more than an industry-standard software package for spreadsheets. In this paper, we shall examine singularly perturbed two point boundary value problems with the boundary layer at one end point. An initial-value technique is used for its solution by replacing the problem with an asymptotically equivalent first order problem, which is, in turn, solved as an initial value problem by using cubic splines. Numerical examples …

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas

Electronic Theses and Dissertations

In this dissertation, the relationship between flow state, serious games, and learning was examined. Serious games, which are games that convey something other than enjoyment (e.g., learning), are increasingly popular platforms for research, training, and advertisement. The elements that make serious games useful to researchers, trainers, and practitioners are closely linked to those that make up the positive psychology construct of flow state. Flow state describes an optimum experience that is encountered when a variety of factors are met, and is characterized by high focus, engagement, motivation, and immersion. While flow state is often discussed in the serious games literature, …

Tiny Supernovas, Jesse Jay Ross

Electronic Theses and Dissertations

This work seeks to expose the truth in as many different forms as possible. As the title, Tiny Supernovas, suggests, it is influenced by the concept of the explosions of super-massive stars. This explosion is known as a supernova. It is only through a supernova, only through the death and subsequent explosion of one of the largest sequence of stars, that we obtain many of the elements necessary for life here on earth. All heavy metals come from supernovas. Everything we and our planet are made from comes from these explosions. Yet, there is a similarly prolific release of energy …

Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver

Electronic Theses and Dissertations

The current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic achievement measures, both initially and at follow-up. Much of this influence, however, was mediated by verbal memory’s contribution to near-term achievement, whereas visuospatial memory contributed more robustly to long-term achievement. For the domain-specific math …

Giant Raman Enhancement On Nanoporous Gold Film By Conjugating With Nanoparticles For Single-Molecule Detection, Lihua Qian, Biswajit Das, Yan Li, Zhilin Yang

Electrical & Computer Engineering Faculty Research

Hot spots have the contradictively geometrical requirements for both the narrowest interstices to provide strong near-field coupling, and sufficient space to allow entrance of the analytes. Herein, a two-step method is employed to create hot spots within hybrid nanostructures, which consist of self-supported nanoporous gold films with the absorbed probes and subsequent nanoparticle conjugates without surface agents or mechanical motion. The molecules confined into 1 nm interstice exhibit 2.9 × 10⁷ times enhancement in Raman scattering compared to pure nanoporous gold. Giant enhancement primarily results from strong near-field coupling between nanopore and nanoparticle, which is theoretically confirmed by finite-difference …

Writing Center Handbooks And Travel Guidebooks : Redesigning Instructional Texts For Multicultural, Multilingual, And Multinational Contexts, Steven K. Bailey

Dissertations, Master's Theses and Master's Reports - Open

In an increasingly interconnected world characterized by the accelerating interplay of cultural, linguistic, and national difference, the ability to negotiate that difference in an equitable and ethical manner is a crucial skill for both individuals and larger social groups. This dissertation, Writing Center Handbooks and Travel Guidebooks: Redesigning Instructional Texts for Multicultural, Multilingual, and Multinational Contexts, considers how instructional texts that ostensibly support the negotiation of difference (i.e., accepting and learning from difference) actually promote the management of difference (i.e., rejecting, assimilating, and erasing difference).

As a corrective to this focus on managing difference, chapter two constructs a theoretical …

More Favorable Combination Of Circumstances Could Hardly Have Been Desired : A Bottom To Top Examination Of The Pittsburgh And Boston Mining Company's Cliff Mine, Sean M. Gohman

Dissertations, Master's Theses and Master's Reports - Open

The Cliff Mine, an archaeological site situated on the Keweenaw Peninsula of Michigan, is the location of the first successful attempt to mine native copper in North America. Under the management of the Pittsburgh & Boston Mining Company from 1845-1879, two-third of the Cliff’s mineral output was in the form of mass copper, some pieces of which weighed over 5 tons when removed from the ground. The unique nature of mass copper and the Cliff Mine’s handling of it make it one of the best examples of early mining processes in the Keweenaw District. Mass copper only constituted 2% of …

Simulating Dioxane Transport In A Heterogeneous Glacial Aquifer System (Washtenaw County, Michigan) Using Publicly Available Models And Data, Rungroj Benjakul

Dissertations, Master's Theses and Master's Reports - Open

The primary challenge in groundwater and contaminant transport modeling is obtaining the data needed for constructing, calibrating and testing the models. Large amounts of data are necessary for describing the hydrostratigraphy in areas with complex geology. Increasingly states are making spatial data available that can be used for input to groundwater flow models. The appropriateness of this data for large-scale flow systems has not been tested. This study focuses on modeling a plume of 1,4-dioxane in a heterogeneous aquifer system in Scio Township, Washtenaw County, Michigan. The analysis consisted of: (1) characterization of hydrogeology of the area and construction of …

The Relationship Between Energy Balance Understanding And Measures Of Wellness, Stephanie Fishel-Brown

All Dissertations

Much emphasis on the fight against obesity is placed on education and food labeling, yet very little research has been performed to measure how much people know about energy balance and the relationship of this knowledge to measures of wellness. The primary objective of this study was to determine if college students' (N = 262) performance on an energy balance questionnaire is associated with measures of wellness. Performance on the questionnaire as a whole was not significantly correlated (p > .05) with body mass index (BMI; r_s = .04), percent body fat (r_s = .05), waist to hip ratio …

One of possible cooperative Situations for flights could be a scenario when the decision on a new path is taken by A Certain fleet member, who is called the leader. The update on the new path is Transmitted to the fleet members via communication That can be noisy. An optical sensor can be used as a back-up for re-estimating the path parameters based on visual information. For A Certain topology, the issue can be solved by continuous tracking of the leader of the fleet in the video sequence and re-adjusting parameters of the flight, accordingly. To solve such a problem …

Tertiary Level Students And The Mental Health Index (Mhi-5) In Ireland, Frank Houghton, Noreen Keane, Niamh Murphy, Sharon Houghton, Claire Dunne

Irish Journal of Applied Social Studies

An examination of student mental health was conducted using the five item Mental Health Index (MHI), a subscale of the widely used SF-36 (Short Form Health Survey). Results support the use of the MHI, which was found to be to be a valid and reliable measure of mental health in Irish third-level students. As anticipated, females reported significantly higher levels of symptoms than males on the MHI. It was also noted that final year students report significantly worse mental health than other students. Comparison with a general population mean for a corresponding age group indicate significantly lower mental health status …

The study hopes to provide new generation of entrepreneurs insights on entrepreneurial styles that need to change to …

Suna No Onna: An Absurd Reading, Charisa Player

BYU Asian Studies Student Journal

Woman in the Dunes (Suna no Onna), written by Kobo Abe, readily lends itself to analysis as an existential novel, which is described as a work that “subverts and ridicules traditional genres of realistic fiction, asserting its non-mimetic autonomy over against the conventional expectations and interpretative customs of the reader” (Goebel). However, because of the way in which the novel presents its world, and the way that the narrative ends, Suna no Onna finds itself in a somewhat separate category from other existentialist texts. In his article “Kobo Abe: Japan’s Kafka,” Goebel explains Abe’s writing in Suna no Onna is …
