An Analysis Of The Relationship Between The Perceptions Of Value-Added Measurement And Teacher Job Satisfaction, Meagan A. Viar
Electronic Theses and Dissertations Archive
Educational leaders are struggling with the issue of academic reform as it pertains to accountability for student achievement. With increasing pressures to improve student achievement, many states have adopted value-added measures to monitor student growth and teacher effectiveness. This study undertook a quantitative approach to examine the relationship between teacher perceptions of value-added evaluations, teachers' three-year mean value-added scores, and teacher job satisfaction using One-Way Analysis of Variance (ANOVAs). The four major questions posed in this study are as follows: 1) What are selected TN teachers' perceptions of the TVAAS-based teacher evaluation system in terms of fairness, accuracy, understandability, and …
Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne
Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne
Dissertations and Theses
Lanthanide chelates are effective agents for improving contrast in MR images. Optimizing the relaxation of inner sphere water molecules is a common focus of research in this field. However, the efforts to design an optimal contrast agent have commonly over-looked the relationship of water position and water exchange kinetics. This work explores structural conformation, the impact of very fast water exchange kinetics on hydration, and differing tumbling rates for regioisomers of a number of lanthanide chelates. We have grown crystals of LnDOTMA and obtained structural data by X-ray diffraction that provide a picture of the chelate during water exchange and …
Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis
Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis
Theses and Dissertations
Longitudinal stream profiles can be used to evaluate landscape evolution. Lithology as a control on a stream profile is especially of interests because fluviokarst systems are characterized by the contact of carbonate and non-carbonate rocks at the surface. Due to the difference in weathering processes between carbonates and non-carbonate rocks, it is likely that there is a difference in their rates of erosion. Cave Branch and its tributary Horn Hollow, are fluviokarst systems located in northeastern Kentucky. This area is primarily comprised of sandstone and limestone. The objectives of this study were to determine if variation in lithology was creating …

Π-Armendariz Rings And Related Concepts, Areej M. Abduldai, Roaa M. Abidali
Baghdad Science Journal
In this paper we investigated some new properties of ��-Armendariz rings and studied the relationships between ��-Armendariz rings and central Armendariz rings, nil-Armendariz rings, semicommutative rings, skew Armendariz rings, ��-compatible rings and others. We proved that if �� is a central Armendariz, then �� is a ��-Armendariz ring. Also, we explained how skew Armendariz rings can be ��-Armendariz, for that we proved that if �� is a skew Armendariz ��-compatible ring, then �� is ��-Armendariz. Examples are given to illustrate the relations between concepts.

Biofilm is an aggregate of consortium bacteria that adhere to each other on a surface. It is usually protected by the exopolysaccharide layer. Various invasive medical procedures, such as catheterization, endotracheal tube installation, and contact lens utilization, are vulnerable to biofilm infection. The National Institute of Health (NIH) estimates 65% of all microbial infections are caused by biofilm. Periplasmic α-amylase (MalS) is an enzyme that hydrolyzes α-1, 4- glicosidic bond in glycogen, starch, and others related polysaccharides in periplasmic space. Another protein called hemolysin-α (HlyA) is a secretion signal protein on C terminal of particular peptide in gram negative bacteria. …

Mitigation Of The Impact Of High Plug-In Electric Vehicle Penetration On Residential Distribution Grid Using Smart Charging Strategies, Chong Cao, Luting Wang, Bo Chen
Michigan Tech Publications, Part 1
Vehicle electrification presents a great opportunity to reduce transportation greenhouse gas emissions. The greater use of plug-in electric vehicles (PEVs), however, puts stress on local distribution networks. This paper presents an optimal PEV charging control method integrated with utility demand response (DR) signals to mitigate the impact of PEV charging to several aspects of a grid, including load surge, distribution accumulative voltage deviation, and transformer aging. To build a realistic PEV charging load model, the results of National Household Travel Survey (NHTS) have been analyzed and a stochastic PEV charging model has been defined based on survey results. The residential …

‘‘Can I Drop It This Time?’’ Gender And Collaborative Group Dynamics In An Engineering Design-Based Afterschool Program, Jessica Schnittka, Christine Schnittka
Journal of Pre-College Engineering Education Research (J-PEER)
The 21st century has brought an increasing demand for expertise in science, technology, engineering, and math (STEM). Although strides have been made towards increasing gender diversity in several of these disciplines, engineering remains primarily male dominated. In response, the U.S. educational system has attempted to make engineering curriculum more engaging, informative, and welcoming to girls. Specifically, project-based and design-based learning pedagogies promise to make engineering interesting and accessible for girls while enculturating them into the world of engineering and scientific inquiry. Outcomes for girls learning in these contexts have been mixed. The purpose of this study was to explore how …
"The Wild East" In Contemporary German Poetry: Gerald Zschorsch, Kurt Drawert, Brigitte Oleschinski, Sabine Egger
"The Wild East" In Contemporary German Poetry: Gerald Zschorsch, Kurt Drawert, Brigitte Oleschinski, Sabine Egger
CALL: Irish Journal for Culture, Arts, Literature and Language
This article discusses images of a “European” or “Wild” East in German poetry after 1989, specifically the work of Gerald Zschorsch, Kurt Drawert and Brigitte Oleschinski. Do their texts confirm or challenge a dichotomy with a long tradition in German and Western European thought, by juxtaposing “Germany” or “Europe” and this “East”, or by aesthetically transcending such a dichotomy? How do their aesthetics open perspectives on inter- or transcultural movement beyond existing ideas of regional, national and European identities in an increasingly globalized world? Focusing on place, space and movement, the article addresses Centre-Periphery dynamics from a new angle. While …
Spatial Translations And Embodied Bilingualism: Defining The Migrant's Experience From An Architectural Perspective, Caroline Rabourdin
Spatial Translations And Embodied Bilingualism: Defining The Migrant's Experience From An Architectural Perspective, Caroline Rabourdin
CALL: Irish Journal for Culture, Arts, Literature and Language
As a bilingual writer and architect, my research is practice-based and multidisciplinary. In pulling together theories and practices about Space, Language and the Body, my aim is to develop a notion of Embodied Bilingualism. If the word ‘translate’ is to move something from one place to another, as architectural historian Robin Evans explains, then one needs to understand its pure and unconditional existence as a geometrical construct in the first place in order to fully appreciate the workings of linguistic translation. In this paper, language is considered as an embodied practice, which for the bilingual migrant leads to considerations about …

An Examination Of Student Outcomes In Studio Chemistry, Alan L. Kiste, Gregory E. Scott, Jesse Paul Bukenberger, Miles Markmann, Jennifer Moore
Chemistry and Biochemistry
Twenty years ago, a major curriculum revision at a large, comprehensive university in the Western United States led to the implementation of an integrated lecture/laboratory (studio) experience for our engineering students taking general chemistry. Based on these twenty years of experience, construction of four purpose-built studio classrooms to house the majority of the remaining general chemistry courses was completed in 2013. A detailed study of the effects of the entire ecology of the studio experience on student success was initiated at that time. Data from content knowledge pre- and post-tests, learning attitudes surveys, and student course evaluations show positive effects …

Trophic Ecology Of Green Turtles (Chelonia Mydas) From Dry Tortugas National Park, Florida, David C. Roche
HCNSO Student Theses and Dissertations
Located 100 km west of Key West, Florida, Dry Tortugas National Park (DRTO) is a largely untouched subtropical marine ecosystem that serves as an important developmental habitat, nesting ground, and foraging area for several species of sea turtles, including green turtles. The Park supports a recovering population of green turtles comprised of resident juveniles, subadults, and adults of both sexes; nesting females include residents and migrating females that only return to nest. Stable isotope analysis has been applied widely to describe the trophic ecology of green turtles, from urbanized bays with significant anthropogenic input, to relatively pristine ecosystems with healthy …

Making The Classroom More Student-Centered, Alyssa R. Johnson
Honors Capstones
The purpose of this thesis is to explore the role of behavior management techniques in the classroom and to determine if students learn best in a student-centered classroom or a teacher-centered classroom. This exploration through interviews and research, will help to find out how teachers create a positive learning environment for a diverse group of students in the classroom and how a student-centered technique versus how a teacher-centered technique works in the classroom. In my opinion, if teachers do not set up a positive learning environment for all students in their classroom, then they will not be in control of …

Formulating A Pharmacy Collection Without A Prescription, Kristin Laughtin-Dunker, Linda Galloway
Library Articles and Research
Librarians without a background in the health sciences were tasked with building a collection to support a new pharmacy school at a traditionally liberal arts institution. Despite little subject expertise, the team assessed current holdings, conducted a review of recommended resources, and collaborated with faculty to prioritize acquisitions to support the developing program as funds became available. The hire of a health sciences librarian provided new opportunities for assessment and for continued collecting. Altogether, this process allowed for the creation of recommended best practices that can be adopted by any librarian procuring resources to support new health science programs.

Solid-state NMR and molecular dynamics (MD) simulations are presented to help elucidate the molecular secondary structure of poly(Gly-Gly-X), which is one of the most common structural repetitive motifs found in orb-weaving dragline spider silk proteins. The combination of NMR and computational experiments provides insight into the molecular secondary structure of poly(Gly-Gly-X) segments and provides further support that these regions are disordered and primarily non-β-sheet. Furthermore, the combination of NMR and MD simulations illustrate the possibility for several secondary structural elements in the poly(Gly-Gly-X) regions of dragline silks, including β-turns, 3

We present a de Haas-van Alphen study of the Fermi surface of the low-temperature antiferromagnet CeZn11 and its nonmagnetic analog LaZn11, measured by torque magnetometry up to fields of 33T and at temperatures down to 320mK. Both systems possess similar de Haas-van Alphen frequencies, with three clear sets of features -- ranging from 50T to 4kT -- corresponding to three bands of a complex Fermi surface, with an expected fourth band also seen weakly in CeZn11. The effective masses of the charge carriers are very light ( < 1me) in LaZn11 but a factor …
