The purpose of this action research project was to determine how my practice of implementing Universal Design for Learning-Representation (UDL-R) principles influenced my students’ understanding of content and enhanced their ability to organize their knowledge using concept maps. A secondary purpose of this action research project was to determine if student created concept maps served as a useful tool to enrich students’ written scientific explanations. Students in this study completed concept maps and wrote explanations about adaptations before and after participating in lessons enriched with UDL-R principles that included the use of multimedia sources, website searches, and trade books. The …

Geographic Variation In Post-Mating Immune Gene Expression In Drosophila Melanogaster, Cheryl Ann Pinzone

Electronic Theses and Dissertations

An organism's immune response may vary due to pathogen pressure in its environment, as well as due to interactions with other organisms. These factors, along with geographic rules (i.e. Gloger's rule) may influence the geographic distribution of the immune response within populations of a species. Here we use real-time quantitative PCR to measure the immune gene expression in six populations collected along the eastern U.S. of Drosophila melanogaster after mating. Antimicrobial genes did not show significant differences in expression due to location, whereas we did observe differences in anti-fungal and pro-phenoloxidase (anti-macromolecule) related genes. These differences in anti-macromolecule resistance are …

Assessing The Psychometric Properties Of The Counseling Competencies Scale A Measure Of Counseling Skills, Dispositions, And Behaviors, Jacqueline Melissa Swank

Electronic Theses and Dissertations

Ethical and competent professional counselors are needed to provide quality counseling services to the public. Counselor educators and supervisors have the responsibility of training competent counselors. Furthermore, counselors and counselors-in-training have the responsibility of continually assessing their own development and implementing measures to increase their competency. Assessment instruments have sought to measure counseling competencies through evaluating counseling skills. However, a paucity of research exists that examines counseling competencies in a comprehensive manner using a psychometrically sound approach. Therefore, a need exists for a psychometrically sound assessment instrument that measures the construct of counseling competencies in a holistic manner. Thus, the …

Acetazolamide-Induced Decrease Of Apical Fluid Flow In Choroid Plexus Is Independent Of The Concomitant Changes In Aquaporin-1 Expression, Pouya Alexander Ameli

Electronic Theses and Dissertations

Acetazolamide (AZA), the only drug approved for treatment of hydrocephalus, is effective in only 25-30% of patients while its effect on fluid flow in the choroid plexus (CP) is unknown. The drug reversibly inhibits Aquaporin 4 (AQP4), the most highly expressed „water pore‟ in the brain, and it is postulated that it reduces cerebrospinal fluid (CSF) production by modulating AQP1 (mostly found in the apical membrane of the CP). In this study, we sought to elucidate the effect of AZA on AQP1 and fluid flow in CP. Primary CP culture from p10 Sprague-Dawley rats and TRCSF-B cell line were grown …

Supporting A Standards-Based Teaching And Learning Environment A Case Study Of An Expert Middle School Mathematics Teacher, Didem Akyuz

Electronic Theses and Dissertations

Although it has been more than 20 years since the publication of Curriculum and Evaluation Standards for School Mathematics (NCTM, 1989) and 10 years since the second version of standards, Principles and Standards for School Mathematics (NCTM, 2000), the research underlines the lack of essential practices for standards-based teaching (Franke, Kazemi, & Battey, 2007). The literature also emphasizes the importance of planning in standards-based teaching, although few studies focus on the direct planning of the teacher (Kilpatrick, Swafford, & Findell, 2001). The aim of the current study was to conduct a case study to extract the planning and classroom practices …

Design, Synthesis And Characterization Of New Two-Photon Absorbing (2pa) Fluorescent Dyes And Bioconjugates, And Their Applications In Bioimaging, Carolina D. Andrade

Electronic Theses and Dissertations

The development of new multiphoton absorbing materials has attracted the attention of researchers for the last two decades. The advantages that multiphoton absorbing materials offer, versus their one-photon absorbing counterparts, rely on the nature of the nonlinearity of the absorption process, where two photons are absorbed simultaneously offering increased 3D resolution, deeper penetration, and less photobleaching and photodamage as a result of a more confined excitation. The applications of efficient two-photon absorbing materials have been extensively expanding into the fields of photodynamic therapy, microscopy, and optical data storage. One of the fields where an increased interest in multiphoton absorbing materials …

Clinical Practice Guidelines For Emerging Ultrasound Applications Drafting For Validity And Usability, Kathi Keaton Borok

Electronic Theses and Dissertations

Clinical practice guidelines (CPGs) are viewed by many people with interests in health care as valuable tools for reducing practice variations that undermine patient outcomes and increase medical costs. However, guidelines themselves vary in quality. Assessment tools generally base quality measures on strength of guidelines' evidence base, but particularly for newly emerging applications of ultrasound, standards for measuring guideline quality are controversial. The validity of a guideline is considered likely when strong research-based evidence supports its recommendations, but for newer medical procedures such as emerging ultrasound applications, available evidence is sparse. Existing assessment tools must be modified if they are …

The Academic Word List Reorganized For Spanish-Speaking English Language Learners, Robert W. Bushong Ii

Electronic Theses and Dissertations

Published in TESOL Quarterly a decade ago, the Academic Word List (AWL) (Coxhead, 2000) has become increasingly influential in the field of TESOL. With more than 82% of the AWL comprised of words of Latin and Greek, much of this important list logically consists of English-Spanish cognates because Spanish originated from Latin. In order to serve Spanishspeaking English language learners (SSELLs) better, their teachers need to know which AWL words are cognates. Using published sources and linguistic analysis of the 570 items in the AWL, the research in this thesis has resulted in a newly reorganized AWL divided into four …

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 …

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 …

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, …

Although water availability was not found to be a challenge globally, geospatial analysis demonstrated that water availability is a potentially …

Proteomic And Physiological Responses Of Leopard Sharks (Triakis Semifasciata) To Salinity Change, W. Wesley Dowd, B. N. Harris, J.J. Chech Jr, D. Kültz

Biology Faculty Works

Partially euryhaline elasmobranchs may tolerate physiologically challenging, variable salinity conditions in estuaries as a tradeoff to reduce predation risk or to gain access to abundant food resources. To further understand these trade-offs and to evaluate the underlying mechanisms, we examined the responses of juvenile leopard sharks to salinity changes using a suite of measurements at multiple organizational levels: gill and rectal gland proteomes (using 2-D gel electrophoresis and tandem mass spectrometry), tissue biochemistry (Na+/K+-ATPase, caspase 3/7 and chymotrypsin-like proteasome activities), organismal physiology (hematology, plasma composition, muscle moisture) and individual behavior. Our proteomics results reveal coordinated molecular responses to low salinity …

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 …

Golden-Winged Warbler Habitat Model Validation For Northern Wisconsin And Central Minnesota, Alexandra E. Wrobel

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

Between 1966 and 2003, the Golden-winged Warbler (Vermivora chrysoptera) experienced declines of 3.4% per year in large parts of the breeding range and has been identified by Partners in Flight as one of 28 land birds requiring expedient action to prevent its continued decline. It is currently being considered for listing under the Endangered Species Act. A major step in advancing our understanding of the status and habitat preferences of Golden-winged Warbler populations in the Upper Midwest was initiated by the publication of new predictive spatially explicit Golden-winged Warbler habitat models for the northern Midwest. Here, I use …

Use Of A 3d Perfusion Bioreactor With Osteoblasts And Osteoblast/Endothelial Cell Co-Cultures To Improve Tissue-Engineered Bone, Matthew J. Barron

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

The delivery of oxygen, nutrients, and the removal of waste are essential for cellular survival. Culture systems for 3D bone tissue engineering have addressed this issue by utilizing perfusion flow bioreactors that stimulate osteogenic activity through the delivery of oxygen and nutrients by low-shear fluid flow. It is also well established that bone responds to mechanical stimulation, but may desensitize under continuous loading. While perfusion flow and mechanical stimulation are used to increase cellular survival in vitro, 3D tissue-engineered constructs face additional limitations upon in vivo implantation. As it requires significant amounts of time for vascular infiltration by the host, …

Differential Gps As A Monitoring Tool On Volcano Santa Ana (Illamatepec) And The Coatepeque Caldera, El Salvador, Hans N. Lechner

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

We used differential GPS measurements from a 13 station GPS network spanning the Santa Ana Volcano and Coatepeque Caldera to characterize the inter-eruptive activity and tectonic movements near these two active and potentially hazardous features. Caldera-forming events occurred from 70-40 ka and at Santa Ana/Izalco volcanoes eruptive activity occurred as recently as 2005. Twelve differential stations were surveyed for 1 to 2 hours on a monthly basis from February through September 2009 and tied to a centrally located continuous GPS station, which serves as the reference site for this volcanic network. Repeatabilities of the averages from 20-minute sessions taken over …
