The Nature And Function Of Professional Support Networks For Teachers Of English Language Learners, Betsy Lynn Ferguson Dec 2015

The Nature And Function Of Professional Support Networks For Teachers Of English Language Learners, Betsy Lynn Ferguson

Theses and Dissertations

The English learner (EL) population in the United States continues to grow. To improve their pedagogy in working with this population, many educators have received training in English as a Second Language (ESL), but the gap between ELs and their native English speaking peers persists. When teachers engage as members of professional support networks, they are more likely to successfully implement the strategies learned in their ESL professional development (Echevarria, Richards-Tutor, Chinn, & Ratleff, 2011). This study considered the nature and function of the professional support network of a district's ESL-endorsed teachers. Using network theory methods, 257 teachers and other …

Configuration Scrubbing Architectures For High-Reliability Fpga Systems, Aaron Gerald Stoddard Dec 2015

Configuration Scrubbing Architectures For High-Reliability Fpga Systems, Aaron Gerald Stoddard

Theses and Dissertations

Field Programmable Gate Arrays (FPGAs) are being used more frequently in space applications because of their reconfigurability and intensive processing capabilities. FPGAs in environments like space are susceptible to ionizing radiation which can cause Single Event Upsets (SEUs) in the FPGA's configuration memory. These upsets may cause the programmed user design on the FPGA to deviate from its normal behavior. Space missions cannot afford to allow important data processing applications to become corrupted due to these radiation upsets.Configuration scrubbing is an upset mitigation technique that detects and corrects upsets in an FPGA's configuration memory. Configuration scrubbing periodically monitors an FPGA's …

A Theory Of Presence: Bringing Students And Art Closer Together, Joshua T. Hobbs Dec 2015

A Theory Of Presence: Bringing Students And Art Closer Together, Joshua T. Hobbs

Theses and Dissertations

In seeking to create a richer learning environment in a junior high art classroom, the author develops a theory of presence. Closely connected to object-centered learning, a theory of presence in the art classroom places value on students being in the presence of, interacting with, and responding to artworks, artists, and other individuals and objects from the visual arts community. The author then describes how curricular plans are influenced by this theory of presence. Using an action research methodology, the author engages in the spiral process of planning, acting, observing, and reflecting on curriculum that explores the possibilities of connecting …

New Genres In The Art Classroom: Shifting Ideas And Identities, Alyssa Grant Ridge Dec 2015

New Genres In The Art Classroom: Shifting Ideas And Identities, Alyssa Grant Ridge

Theses and Dissertations

Secondary art education programs primarily offer courses in traditional mediums like drawing, painting, sculpture, and ceramics. In addition to valuing these traditional art forms, art education research supports integrating new technologies and media in the classroom. However, the possibilities of creating an exclusively contemporary, new genres curriculum have yet to be explored. This study examines the affordances and limitations of a high school-level new genre curriculum and describes how students reacted to these new genres and how their perceptions of art, student-peer relationships, and artist identities changed over time. By introducing students to new genres, the author found students expanded …

Numerical Analysis Of Passive Force On Skewed Bridge Abutments, Zifan Guo Dec 2015

Numerical Analysis Of Passive Force On Skewed Bridge Abutments, Zifan Guo

Theses and Dissertations

Accounting for seismic forces and thermal expansion in bridge design requires an accurate passive force-deflection relationship for the abutment wall. Current design codes make no allowance for skew effects on passive force; however, large scale field tests indicate that there is a substantial reduction in peak passive force as skew angle increases. A reduction in passive force also reduces the transverse shear resistance on the abutment. The purpose of this study is to validate three-dimensional model using PLAXIS 3D, against large scale test results performed at Brigham Young University and to develop a set of calibrated finite element models. The …

Evidences Of Critical Thinking In The Writing Of First-Year College Students, Shannon Bryn Soper Dec 2015

Evidences Of Critical Thinking In The Writing Of First-Year College Students, Shannon Bryn Soper

Theses and Dissertations

A healthy civil society depends on citizens who have mature critical thinking skills and a willingness to entertain opposing points of view. The development of critical thinking in young adults has long been studied, but there has been little agreement on what the attributes of critical thinking are and how to reliably assess them. While many studies have attempted to assess the critical thinking abilities of college students, none have yet measured critical thinking through using the Critical Thinking Analytic Rubric (CTAR) to assess first-year college students' writing. This study used a modified version of the CTAR rubric to investigate …

Diversification And Speciation Across Sundaland And The Philippines: The Effects Of 30 Million Years Of Eustatic Flux, Luke J. Welton

Theses and Dissertations

I highlight two squamate lineages endemic to Southeast Asia, the Asian water monitors (Varanus salvator Complex) and the Angle-headed lizards (Agamidae: Gonocephalus), and elucidate their systematic affinities and historical biogeography. My results represent novel phylogenetic inferences, with biogeographic histories and diversification events corresponding to major climatic fluctuations over the past 30 million years. Additionally, I solidify the taxonomy and systematics of the Varanus salvator Complex, and enumerate more than a dozen Gonocephalus lineages as candidate species in need of taxonomic scrutiny. Lastly, I investigate contemporary and historical patterns of dispersal throughout Sundaland, and between Sundaland and the Philippines.

Comparing The Strength Of Diagonally Non-Recursive Functions In The Absence Of Σ02 Induction, Francois G. Dorais, Jeffry L. Hirst, Paul Shafer Dec 2015

Comparing The Strength Of Diagonally Non-Recursive Functions In The Absence Of Σ02 Induction, Francois G. Dorais, Jeffry L. Hirst, Paul Shafer

Dartmouth Scholarship

We prove that the statement "there is a k such that for every f there is a k-bounded diagonally non-recursive function relative to f" does not imply weak K\"onig's lemma over RCA0+BΣ02. This answers a question posed by Simpson. A recursion-theoretic consequence is that the classic fact that every k-bounded diagonally non-recursive function computes a 2-bounded diagonally non-recursive function may fail in the absence of IΣ02.

From Networked Learning To Operational Practice: Constructing And Transferring Superintendent Knowledge In A Regional Instructional Rounds Network, Timothy J. Travis Dec 2015

From Networked Learning To Operational Practice: Constructing And Transferring Superintendent Knowledge In A Regional Instructional Rounds Network, Timothy J. Travis

Dissertations

Instructional rounds are an emerging network structure with processes and protocols designed to develop superintendents’ knowledge and skills in leading large-scale improvement, to enable superintendents to build an infrastructure that supports the work of improvement, to assist superintendents in distributing leadership throughout their district, and to develop a cadre of educational leaders focused on developing their practice (Rallis, Tedder, Lachman, & Elmore, 2006). In a platform-learning model, learning in a superintendents’ network can be viewed as occurring both individually and collectively on an external platform outside each individual school district (Schulz & Geithner, 2010). In this phenomenological study, I explored …

Eye Tracking Recycle Labels On Packaging: Are Attitudes And Behaviors A Predictor Of Viewing Them?, Valerie Smith

All Theses

In the United States, the use of the chasing arrows is the most recognizable label for consumers to interpret the recyclability of packaging and other materials. Yet, the use of the label can be used interchangeably for different purposes, which may lead to misinterpretation of the label. Recently, the Sustainable Packaging Coalition (SPC) revamped the recycle label to provide more information, avoid confusion, and misinterpretation. Recycle rates have only increased seven percent in the past decade. Furthermore, there is a lack of research about the utility of recycle labels in efforts to increase recycling rates. The over-arching goals of this …

The Mediating Effects Of Positive Psychological States On The Relationships Between Hindrance Stressors And Organizational Citizenship Behaviors: A Multi-Level Approach, Kandice Goguen

All Theses

Organizational citizenship behaviors (OCBs) are informal and voluntary behaviors that positively contribute to organizational functioning (Organ 1997; Katz & Kahn, 1978). To better understand and encourage such behaviors, the present study investigated the influence of hindrance stressors and positive psychological states in the workplace. Responses from a sample of university employees were analyzed to examine the individual and unit-level effects of role ambiguity, organizational constraints, and lack of job control on individual-level supervisor-rated OCBs through individual and unit-level positive psychological states. Results showed that each hindrance stressor negatively influenced OCB participation directly and through decreased positive psychological states at the …

Control Of Thermoforming Process Parameters To Manufacture Surfaces With Pin-Based Tooling, Vijay Sarthy Mysore Sreedhara Dec 2015

Control Of Thermoforming Process Parameters To Manufacture Surfaces With Pin-Based Tooling, Vijay Sarthy Mysore Sreedhara

All Theses

Many manufacturing processes used to mass produce parts rely on expensive and time consuming tooling. These processes include sheet metal forming, injection molding, casting, and thermoforming. The time invested in design and development of tooling can be justified for high-production volumes. However, for low-volume production and customized products, the tooling investment cannot be amortized. Flexible tooling has been developed to address the needs of smaller production volumes. Reconfigurable pin tooling is an example of flexible tooling that relies on a matrix of adjustable-height pins to produce approximate surfaces. A key challenge in pin-based tooling is achieving accurate high quality surfaces …

Feasibility Study Of Porous Media Compressed Air Energy Storage In South Carolina, United States Of America, Alexandra-Selene Jarvis

All Theses

Renewable Energy Systems (RES) such as solar and wind, are expected to play a progressively significant role in electricity production as the world begins to move away from an almost total reliance on nonrenewable sources of power. In the US there is increasing investment in RES as the Department of Energy (DOE) expands its wind power network to encompass the use of offshore wind resources in places such as the South Carolina (SC) Atlantic Coastal Plain. Because of their unstable nature, RES cannot be used as reliable grid-scale power sources unless power is somehow stored during excess production and recovered …

Multiplier Operator On Framed Hilbert Spaces, Haodong Li Dec 2015

Multiplier Operator On Framed Hilbert Spaces, Haodong Li

All Theses

Very often the operators that we study appear most naturally in highly non-diagonal representation. The main goal of spectral theory is to solve this problem by exhibiting for many operators a natural orthonormal basis with respect to which the operators have diagonal representations. However, this can be done only for certain classes of operators. The most important such class is probably the class of compact operators. The problem is that it is often hard to tell whether an operator is compact looking at its non-diagonal representation. In this thesis, we will study a class of operators for which we can …

Structural Optimization Using Parametric Programming Method, Krupakaran Ravichandraan Dec 2015

Structural Optimization Using Parametric Programming Method, Krupakaran Ravichandraan

All Theses

The Parametric Programming method is investigated to consider its applicability to structural optimization problems. It is used to solve optimization problems that have design variables as implicit functions of some independent input parameter(s). It provides optimal solutions as a parametric function of the input parameter(s) for the entire parameter space of interest. It does not require the detailed discrete optimizations needed at a large number of parameter values as in traditional non-parametric optimization. Parametric programming is widely used in optimal controls, model predictive control, scheduling, process synthesis and material design under uncertainty due to the above mentioned benefits. Its benefits …

Long-Term Winter Inversion Properties In A Mountain Valley Of The Western United States And Implications On Air Quality, Shih-Yu (Simon) Wang, Lawrence E. Hipps, Oi-Yu Chung, Robert R. Gillies, Randy S. Martin

Civil and Environmental Engineering Faculty Publications

Because of the geography of a narrow valley and surrounding tall mountains, Cache Valley (located in northern Utah and southern Idaho) experiences frequent shallow temperature inversions that are both intense and persistent. Such temperature inversions have resulted in the worst air quality in the nation. In this paper, the historical properties of Cache Valley’s winter inversions are examined by using two meteorological stations with a difference in elevation of approximately 100 m and a horizontal distance apart of ~4.5 km. Differences in daily maximum air temperature between two stations were used to define the frequency and intensity of inversions. Despite …
