Teaching For Global Learning Through Telecollaboration: A Case Study Of K-12 Educators' Conceptualizations And Practices About Global Education, Holly Gooding Oran

Dissertations, Theses and Capstone Projects (Full IR Collection)

A plethora of literature discusses the flattening of the world we live in (Friedman, 2007) and the need for teachers to educate K-12 students for global learning. However, the literature is critically lacking in empirical evidence in how this is to take place in classrooms. In addition, existing empirical studies have focused primarily on American social studies educators at the secondary school level. Scholars differ in their own understanding of what global education means and should look like in schools, how teachers are to incorporate it into their curriculum, and how it benefits K-12 learners. The purpose of the present …

The Effects Of Peer Coaching For Technology Integration On Teachers’ Comfort, Practice, And Student Technology Literacy, Tricia Cauffiel Frazier

Dissertations, Theses and Capstone Projects (Full IR Collection)

The purpose of this eight week mixed methods study was to understand the effects of peer coaching on teacher’s comfort, instructional practices, and the culminating impact on student achievement. Through collaborative lesson planning, teachers learned how to improve student learning with technology. The data revealed that though change in comfort was only approaching significance, teachers’ personal statements demonstrated improved comfort. Similarly, change in practices with technology was found to be non-significant; however, observations and interviews indicated that teachers did indeed initiate changes in their instructional practices with technology. Student technology literacy scores also improved significantly from pre- to post-assessment. The …

A Qualitative Study Of The Use Of Content-Related Comics To Promote Student Participation In Mathematical Discourse In A Math I Support Class, Jeni M. Halimun

Dissertations, Theses and Capstone Projects (Full IR Collection)

The purpose of this study is to contribute to existing research on classroom discourse by investigating whether a content-related comic that is closely linked to the learning task can stimulate mathematical discourse in a real high school classroom. To build a math-talk learning community and to analyze the effectiveness of content-related comics in eliciting student participation, I employed the combined theoretical frameworks consisting of a Hufferd-Ackles’ et al. (2004) math-talk learning community and Nathan and Knuth’s (2003) social and analytical scaffolding. The combined frameworks provided a multilevel analytical tool for studying classroom interactions. The results suggested that the content-related comic …

A Critical Examination Of The Relationship Between Student Performances On Assessments Of English Language Proficiency And Academic Achievement, Margaret E. D. Baker

Dissertations, Theses and Capstone Projects (Full IR Collection)

To comply with federal accountability requirements, English learners (ELs) in Georgia must demonstrate progress in academic English language proficiency (ELP) and academic content-area achievement as measured annually by two state-mandated Title I and Title III assessments, the Accessing Communication and Comprehension in English State-to-State for English Language Learners® (ACCESS for ELLs®) and the Criterion-Referenced Competency Test (CRCT). Using a critical ELP assessment validation framework, the intent of this study was to investigate the relationship of students’ performances on Title assessments, analyze student level variability in the predictive power of the ELP assessment for academic achievement, and examine claims made when …

Writing Across The Curriculum: Case Studies Of Three Content-Area Teachers, Patsy A. Hamby

Dissertations, Theses and Capstone Projects (Full IR Collection)

In a qualitative study in a school district transitioning from rural to suburban based on a population growth and a shift in demographics, attitudes about writing, writing practices, writing assignments, and assessment practices of three teachers in the curriculum content areas of math, science, and social studies were investigated. Individual interviews with the teachers, observations of their classroom practices, interviews with focus groups in their content areas, and examinations of rated assessments provided the data for the study. The results indicated that the teachers’ past negative experiences with writing reflect in their teaching practice, as all are reluctant to generate …

A Balanced Approach To Health: Understanding The Health Care Practices Of Guatemalan Maya In The United States, Amanda L. Mcgrew

Dissertations, Theses and Capstone Projects (Full IR Collection)

The Maya worldview is constructed on the concept of balance. Their traditional beliefs emphasize balancing the spiritual and physical forces in their lives to maintain equilibrium and thus, health. Nevertheless, outside forces have impinged heavily on this worldview, often shifting Maya views on health. Discussions with Maya partners throughout the United States revealed that though they do utilize ethnomedicine, they tend to overvalue biomedical techniques and caregivers—even if they do not seek care from them. Maya history, cultural identity, and the experience of diaspora shape the way Maya immigrants view their health and their health care options, often leading them …

A Comparative Analysis Of Effective School Board Leadership: The Case Of Gwinnett County And Atlanta City Public Schools, Joshua Allen Garner

Dissertations, Theses and Capstone Projects (Full IR Collection)

A quality education is essential in determining the success of future generations. All too often K-12 school systems fail to meet the expectations of success held by students, parents, and the community. On the other hand, there are school systems that surpass expectations of success held by stake holders of the school system. Exemplifying this phenomenon is the case of Atlanta Public Schools, who were placed on probation by the accreditation agency, the Southern Association of Colleges and Schools, and the case of Gwinnett County Public Schools, who were awarded the 2010 Broad Award for minority student achievement (Torres 2011) …

A Comparative Study Of International And American Study Abroad Students’ Expectations And Experiences With Host Countries In Selected Institutions Of Higher Education, Jasmine Renner, Evelyn D. Roach

ETSU Faculty Works

This was a comparative study of international and American study abroad students’ experiences and expectations with the host countries. The rationale for this study was to acquire a deeper understanding of different experiences of students who study abroad and to understand whether their expectations of the host country have an impact on their experiences. An opportunity sample of American study abroad and international students was selected from the United States student population and their expectations and experiences of the host country compared. The study addressed 6 research questions, using a mixed-method approach. The principal instrument for the investigation was the …

Flame Retardancy Of Polymer Nanocomposites Based On Layered Aluminum Phosphate And Computational Study Of Intercalation Of Amines Into Α-Zirconium Phosphate And Adsorption Of A Model Organic Pollutant, Ning Wang 1982-

Master's Theses (2009 -)

Layered metal materials, such as layered metal hydroxides, hydroxy double salts, and layered metal phosphates can be used for applications such as fire retardancy, ion exchangers, or removal of pollutants. Optimization of materials for these applications requires an understanding of their physical and chemical properties.

Part A: Flame retardancy of polymer nanocomposites based on taranakite

Taranakite with tunable interlayer spacing has been prepared and modified by sodium dodecyl sulfate (AL-SDS). The layered materials are used as the additive to study the fire retardancy of polymers, including polystyrene (PS), polypropylene (PP), and polyvinyl alcohol (PVA). The dispersion of taranakite was characterized …

Privacy In "The Cloud": Applying Nissenbaum's Theory Of Contextual Integrity, Frances Grodzinsky, Herman T. Tavani

School of Computer Science & Engineering Faculty Publications

The present essay is organized into five main sections. We begin with a few preliminary remarks about "cloud computing," which are developed more fully in a later section. This is followed by a brief overview of the evolution of Helen Nissenbaum's framework of "privacy as contextual integrity." In particular, we examine Nissenbaum's "Decision Heuristic" model, described in her most recent work on privacy (Nissenabum 2010), to see how it enables the contextual-integrity framework to respond to privacy challenges posed by new and emerging technologies. We then apply that heuristic device to questions surrounding one aspect of cloud computing -- viz., …

Decision Support Systems For Strategic Dispute Resolution, Anurag Agarwal, Sridhar Ramamoorti, Vaidyanathan Jayaraman

Faculty Articles

Disputes and lawsuits are quite common in business and are often a source of significant liabilities. We conjecture that measurement challenges and lack of adequate analysis tools have greatly inhibited the ability of the General Counsel's offices in selecting the best mode for the resolution (i.e. litigation vs. out-of-court settlement) of business conflicts and disputes. Easily quantified direct costs (e.g., out-of-pocket expenses related to pursuing and defending against litigation) tend to be considered, whereas the more difficult-to-quantify indirect risks and costs (e.g., damaged relationships with customers and potential alliance partners, including reputational harm) which may be quite significant, tend to …

Application Of Engineered Porosity And Modified Effective Moduli To The Design Of Orthopaedic Implants, John Anthony Choren

Dissertations (1934 -)

Commercially available orthopaedic implants have a bending stiffness (flexural rigidity) that is at least 10 times greater than cortical bone. Effects of this stiffness mismatch have been extensively studied relative to total hip arthroplasty (THA). Clinical experience with THA has shown that stiffness mismatch is the primary cause of accelerated bone resorption due to the stress shielding, resulting in sub-optimal bone loading, aseptic loosening and inadequate bone support for a future revision implant.

Attempts to incorporate design features that reduce the flexural rigidity of implants have yielded inconsistent results or failures due to biomaterial incompatibilities and practical manufacturing complications. The …

Quantitative Evaluation Of Redox Processes In Intact Rat Lungs And Endothelial Cells And The Effect Of Hyperoxia, Zhuohui Gan

Dissertations (1934 -)

A common initial treatment of hypoxemia in patients with lung failure secondary to acute lung injury (e.g., adult respiratory distress syndrome) is oxygen (O₂) therapy (hyperoxia). However, prolonged O₂ therapy causes lung O₂ toxicity, which can further impair lung functions. The rat model of lung O₂ toxicity replicates key features of human lung O₂ toxicity. In addition, rats develop tolerance or susceptibility to 100% O₂ by pre-exposing them to 85% O₂ (hyper-85) or 60% O₂ (hyper-60) for 7 days, respectively. Therefore, the long-term objectives of this study are to elucidate mechanisms …

Fluorescence Probes For Cellular Thiol And Disulfide Detection: Sythesis And Biophysical Characterization, Timothy Jonhera

Dissertations (1934 -)

The total concentration of cellular thiols is about 30 mM, and use of current fluorescent chemical probes to quantitate these thiols inside cells is impractical. We recently reported fluorescent dithio probes (donor-S-S-acceptor, DSSA) with unusually low reduction potential (- 0.6 V) that can detect changes in intracellular thiols and cross membranes of bacterial and mammalian cells, but they could not quantify thiol redox state. Here we report a new variant of the DSSA series, which has hydroxy coumarin (Ex: 320 nm, Em: 460 nm) as donor and fluorescein (Ex: 485 nm, Em: 520 nm) as acceptor. The probe was characterized …

Development, Kinetic Analysis And Applications Of 2-D Nanostructured Layered Metal Hydroxides, Stephen Majoni

Dissertations (1934 -)

Nanodimensional layered metal hydroxides which include layered hydroxy salts (LHSs) and hydroxy double salts (HDSs) have the ability to accommodate species between the layers. The structural composition of these materials can be tuned so as to create materials with targeted physico-chemical properties for applications where it is advantageous to intercalate or release molecules. Some of the applications include ion-exchange, fire retardation, catalysis, and controlled release delivery. Anion exchange reactions are among methods used to optimize these materials for targeted applications, making the characterization of exchange kinetics of practical interest. In addition, understanding fundamental factors that control retention and release of …

Incorporating The Aortic Valve Into Computational Fluid Dynamics Models Using Phase-Contrast Mri And Valve Tracking, David C. Wendell

Dissertations (1934 -)

The American Heart Association states about 2% of the general population have a bicuspid aortic valve (BAV). BAVs exist in 80% of patients with aortic coarctation (CoA) and likely influences flow patterns that contribute to long-term morbidity post-surgically. BAV patients tend to have larger ascending aortic diameters, increased risk of aneurysm formation, and require surgical intervention earlier than patients with a normal aortic valve. Magnetic resonance imaging (MRI) has been used clinically to assess aortic arch morphology and blood flow in these patients. These MRI data have been used in computational fluid dynamics (CFD) studies to investigate potential adverse hemodynamics …

Circulation Of The Western Antarctic Peninsula: Implications For Biological Production, Maria Andrea Piñones Valenzuela

OES Theses and Dissertations

The western Antarctic Peninsula (wAP) continental shelf is characterized by large persistent populations of Antarctic krill ( Enphausia superba) and by regions of enhanced concentrations of marine mammals and other predators (hot spots). This study focused on understanding the role of ocean circulation in providing retention/connectivity of wAP Antarctic krill populations and in maintaining biological hot spot regions. Numerical Lagrangian particle tracking simulations obtained from the Regional Ocean Modeling System (ROMS) configured for the wAP region provided quantitative estimates of retention, immigration and emigration from the wAP continental shelf. Additional simulations with a one-dimensional temperature-dependent growth model for krill …

Improving The Fda Approval Process, Mark Van Der Laan, Anup Malani, Oliver Van Der Bembom

Public Law and Legal Theory Working Papers

The FDA employs an average-patient standard when reviewing drugs: it approves a drug only if is safe and effective for the average patient in a clinical trial. It is common, however, for patients to respond differently to a drug. Therefore, the average-patient standard can reject a drug that benefits certain patient subgroups (false negative) and even approval a drug that harms other patient subgroups (false positives). These errors increase the cost of drug development – and thus health care – by wasting research on unproductive or unapproved drugs. The reason why the FDA sticks with an average patient standard is …

Disaggregating Time Series Data For Energy Consumption By Aggregate And Individual Customer, Steven Vitullo

Dissertations (1934 -)

This dissertation generalizes the problem of disaggregating time series data and describes the disaggregation problem as a mathematical inverse problem that breaks up aggregated (measured) time series data that is accumulated over an interval and estimates its component parts.

We describe five different algorithms for disaggregating time series data: the Naive, Time Series Reconstruction (TSR), Piecewise Linear Optimization (PLO), Time Series Reconstruction with Resampling (RS), and Interpolation (INT). The TSR uses least squares and domain knowledge of underlying correlated variables to generate underlying estimates and handles arbitrarily aggregated time steps and non-uniformly aggregated time steps. The PLO performs an adjustment …

Nmr And Computational Studies Of Nad(P)(H) Cofactor Binding, Junghwa Kim

Master's Theses (2009 -)

Tuberculosis (TB) is one of the most dangerous diseases in a sense of spread method. According W.H.O., one third of world population has this disease and annual one of these infected people spreads 10 -15 people unintentionally. To protect human from this bacterial, the unique feature of mycrobacterial [sic] TB was studied previously. The unique cell wall, peptidoglycan, has high content of DAP (diaminopimelic acid). The disruption of synthesis DAP results in cell death due to instability of cell wall. One way to inhibiting synthesis of DAP is to modify cofactor which acts with dehydrogenase. To do that the study …
