Low Dimensionality Effects In Complex Magnetic Oxides, Paula J. Lampen Kelley

USF Tampa Graduate Theses and Dissertations

Complex magnetic oxides represent a unique intersection of immense technological importance and fascinating physical phenomena originating from interwoven structural, electronic and magnetic degrees of freedom. The resulting energetically close competing orders can be controllably selected through external fields. Competing interactions and disorder represent an additional opportunity to systematically manipulate the properties of pure magnetic systems, leading to frustration, glassiness, and other novel phenomena while finite sample dimension plays a similar role in systems with long-range cooperative effects or large correlation lengths. A rigorous understanding of these effects in strongly correlated oxides is key to manipulating their functionality and device performance, …

The Action Cycle/Structural Context Framework: A Fisheries Application, D. G. Webster

Dartmouth Scholarship

There is a growing consensus that environmental governance is a wicked problem that requires understanding of the many linkages and feedbacks between human and natural systems. Here, I propose an action cycle/structural context (AC/SC) framework that is based on the concept of responsive governance, in which individuals and decision makers respond to problems rather than working to prevent them. By linking agency and structure, the AC/SC framework points out two key problems in the realm of environmental governance: the profit disconnect, whereby economic signals of environmental harm are dampened by endogenous or exogenous forces, and the power disconnect, whereby those …

Should Sports Drinks Be Given To Children And Adolescents Engaged In Athletics As An Effective Source Of Hydration?, Zeev W. Rubinson

The Science Journal of the Lander College of Arts and Sciences

Dehydration in children and adolescents is a major concern for caretakers. Often children are not drinking enough, particularly while participating in physical activity. Utilizing data drawn from pediatricians, nutritionists, and bio-scientists, this paper will examine whether sports drinks are a good source of fluids for the exercising child. The results of the research indicate that the advantages generally associated with sports drinks, to achieve higher body water absorption levels, prevent electrolyte deficits, and maintain proper electrolyte/water concentrations, are reserved for unique circumstances. Sports drink intake should be encouraged only when the child is participating in prolonged physical activity, in intense …

The Neurological Underpinnings Of Hypnosis And Its Clinical Applications, Raizy Leizerowski

The Science Journal of the Lander College of Arts and Sciences

The brain is so complex that it is almost impossible to select one variable as the reason for a specific observation. This paper will discuss the neurological basis of hypnosis, and how hypnosis has made unique contributions to the refinement and development of cognitive neuroscience. In addition, hypnosis has been proven to cure many psychological and neurologically based diseases. Due to in-depth study of the neurological underpinnings of hypnosis, much advancement has been made in elucidating the relationship between the complex neural circuitry of the brain, its direct correlation to consciousness, and both the efferent and afferent neurological systems. New …

Fostering Critical Thought Alongside The Common Core State Standards, Bianca Arias

University Honors Theses

This thesis evaluates a segment of the second grade English language arts and literacy (ELA) curriculum presently utilized in Portland Public Schools (PPS) school district in Portland, Oregon, using five principles for evaluation. These principles address the extent to which lessons are hands-on, engage home life, integrate the academic disciplines, encourage student autonomy, and are relevant to society today. These criteria were established following a review of John Dewey’s ideas and philosophies, and of two practices that model Deweyan principles: Project-Based Learning (PBL) and progettazione in the Municipal Infant/Toddler Centers and Preschools of Reggio-Emilia, Italy. This analysis of the ELA …

That Mysterious, Remisse Knot: Katherine Philips's Unincorporated Fraternity, Rene Kramer

University Honors Theses

Recent critics in early modern poetry, women’s literature, and queer studies have attempted to factor Katherine Philips’s friendship poetry into a history of homoerotic suspicion. Her metaphysical poems have been offered as a publically significant, potential erotics of textual, rather than physical, embodiment. This thesis responds by returning to the significance of the in-significance of textual representations of feminine erotics, as well as to earlier criticism of Philips as a poet of non-public life and chastity. An examination of notions of innocence in Philips’s configurations of friendship highlights an excess of innocence and a passion predicated on exception, restraint, and …

Analyzing Riboswitches As A Function Of Genome Size And Genus Ancestry In Gammaproteobacteria, Robyn Reid

University Honors Theses

Riboswitches are RNA molecules that regulate gene expression, without the need for protein factors, at the mRNA level in the bacterial kingdom. This paper focuses on nine riboswitches: TPP, FMN, SAM, Lysine, Cobalamine, Glycine, Molybdenum, Mg, and SAH, and whether or not there exists a relationship between genome size and riboswitch existence. The hypothesis of this paper is that there does exist a direct relationship because it is assumed that the more basepairs (bp) in a genome, the higher the chance that an old characteristic, such as a riboswitch, is conserved. Three hundred twenty members of the gammaproteobacteria class were …

On The Role Of Probability In Hume's Imagination And Associationism: A Bayesian Response To Fodor's Hume Variations, Jason Krivo Flores

University Honors Theses

In his 2003 book Hume Variations, Jerry Fodor argues the Computational Theory of Mind (CTM) has obviated the need for Hume's associationism and faculty of imagination. Contrary to Fodor, in this paper I argue that contemporary Bayesian models of cognitive science suggest that Hume’s account continues to comprise a viable theory of mental operations. I propose a Bayesian interpretation of Hume's associationism wherein the "liberty of the imagination to transpose and change its ideas" is accounted for by the contributions of randomness, noise, or stochasticity--i.e., probability.

If my analysis is on track, Fodor has misconstrued the Humean mind by interpreting …

Robust Fast Direct Integral Equation Solver For Quasi-Periodic Scattering Problems With A Large Number Of Layers, Min Hyung Cho, Alex H. Barnett

Dartmouth Scholarship

We present a new boundary integral formulation for time-harmonic wave diffraction from two-dimensional structures with many layers of arbitrary periodic shape, such as multilayer dielectric gratings in TM polarization. Our scheme is robust at all scattering parameters, unlike the conventional quasi-periodic Green’s function method which fails whenever any of the layers approaches a Wood anomaly. We achieve this by a decomposition into near- and far-field contributions. The former uses the free-space Green’s function in a second-kind integral equation on one period of the material interfaces and their immediate left and right neighbors; the latter uses proxy point sources and small …

Robust And Efficient Solution Of The Drum Problem Via Nyström Approximation Of The Fredholm Determinant, Lin Zhao, Alex Barnett

Dartmouth Scholarship

The “drum problem''---finding the eigenvalues and eigenfunctions of the Laplacian with Dirichlet boundary condition---has many applications, yet remains challenging for general domains when high accuracy or high frequency is needed. Boundary integral equations are appealing for large-scale problems, yet certain difficulties have limited their use. We introduce the following two ideas to remedy this: (1) We solve the resulting nonlinear eigenvalue problem using Boyd's method for analytic root-finding applied to the Fredholm determinant, and we show that this is many times faster than the usual iterative minimization of a singular value. (2) We fix the problem of spurious exterior resonances …

Library Faculty and Staff Publications and Presentations

This article provides an overview of the design, implementation, revision and informal assessment of an information literacy curriculum embedded in a new University Foundations (UF) program at a mid‐sized public university. The library information literacy sessions incorporated teambased learning and Process Oriented Guided Inquiry Learning (POGIL) elements using iPads. Each session provided students an opportunity to develop and apply information literacy skills, and included critical thinking questions which led students to think about underlying concepts. A focus group with the librarians assessed the UF library curriculum, its impact on student engagement, and the training activities for librarian teaching preparation.

Impact Of Spatial Aliasing On Sea-Ice Thickness Measurements, Cathleen Geiger, Hans-Reinhard Müller, Jesse P. Samluk, E Rachel Bernstein, Jacqueline Richter-Menge

Dartmouth Scholarship

We explore spatial aliasing of non-Gaussian distributions of sea-ice thickness. Using a heuristic model and >1000 measurements, we show how different instrument footprint sizes and shapes can cluster thickness distributions into artificial modes, thereby distorting frequency distribution, making it difficult to compare and communicate information across spatial scales. This problem has not been dealt with systematically in sea ice until now, largely because it appears to incur no significant change in integrated thickness which often serves as a volume proxy. Concomitantly, demands are increasing for thickness distribution as a resource for modeling, monitoring and forecasting air–sea fluxes and growing human …

This study involves geographic variables of the urban landscape and how they affect bird species assemblage. I utilized bird point count data from observation sites in the Portland, OR metropolitan region provided by Portland Environmental Services. Species data and its relationship with environmental variables were evaluated using Bray-Curtis Dissimilarity measurements together with Non-metric Multidimensional scaling (NMDS) to provide a clear image of the spatial relationships between sites. Land classification, water and canopy in 500 m buffers were quantified in order to describe important geographic variability among collection areas of bird data. Patterns indicating spatial trends in the urban landscape emerged. …

Explaining The "Pulse Of Protoplasm": The Search For Molecular Mechanisms Of Protoplasmic Streaming, Michael Dietrich

Dartmouth Scholarship

Explanations for protoplasmic streaming began with appeals to contraction in the eighteenth century and ended with appeals to contraction in the twentieth. During the intervening years, biologists proposed a diverse array of mechanisms for streaming motions. This paper focuses on the re-emergence of contraction among the molecular mechanisms proposed for protoplasmic streaming during the twentieth century. The revival of contraction is a result of a broader transition from colloidal chemistry to a macromolecular approach to the chemistry of proteins, the recognition of the phenomena of shuttle streaming and the pulse of protoplasm, and the influential analogy between protoplasmic streaming and …

Technology In Transformative Learning Environments, Michael Hamlin

Touro College Los Angeles Publications and Research

Health science educators are increasingly bombarded with proposals to integrate instructional technology into the curriculum to enhance learning. While it may be that providing more options for delivering instruction in different formats provide instructional benefit for educators, the unique nature and goals of health science education require a systematic and integrative approach when instructional technology is introduced into the curriculum. Providing support for transformative learning pedagogies and high-level learning that assists students in developing a reflective professional identity should be a major goal of instructional technology adoption. This chapter develops a framework that health care educators can use to guide …

Judges As Framers Of Plea Bargaining, Daniel S. Mcconkie Jr.

Faculty Articles, Papers, and Other Scholarship

The vast majority of federal criminal defendants resolve their cases by plea bargaining, with minimal judicial input or oversight. This presents significant issues concerning transparency, fairness, and effective sentencing. Federal prosecutors strongly influence sentences by the charges they select. The parties bargain informally outside of court and strike a deal. But defendants often plead guilty without a realistic understanding of their likely sentencing exposure. Instead, they plead guilty based on their best guess as to how judges will resolve certain issues and their own fear that they could get an unspecified but severe post-trial sentence. The judge is often reluctant …

Framing Theory And Its Application To The Fracking Controversy In St. Tammany Parish, Lindsay Colleen Rabalais

LSU Master's Theses

When Helis Oil & Gas Company announced it was interested in drilling for oil in Louisiana’s St. Tammany Parish, it ignited a firestorm. The proposed drilling project would use hydraulic fracturing – or “fracking” – causing some residents to voice their concerns for the parish’s wellbeing. My thesis looks to framing theory to analyze how local media covered the issue, as well as the effects those frames might have on public policy and the lawsuits that arose out of the proposed drilling operation. I performed quantitative and qualitative content analyses of local media coverage of this issue from April 2014 …

The Effect Of Teacher Vs. Student-Set Performance Goals On Academic Achievement In A Middle School Science Classroom, Tyne Nicole Courville

LSU Master's Theses

Self-regulation and self-efficacy are both necessary for students to be independent learners. During middle school, students begin to yearn for academic autonomy, but lack the ability to regulate themselves and are unreasonable about their abilities. Goals have been proven to promote the development of these two skills. The purpose of this investigation was to determine which type of performance goal most efficiently promotes the development of self-regulation. The effects of performance goal source were analyzed to determine if teacher-assigned or student assigned performance goals produce greater growth in content knowledge for seventh grade life science students. The effects of goal …

Factors Influencing Mottled Duck Nest Success On The Atchafalaya River Delta, Brendan Caillouet

LSU Master's Theses

The Atchafalaya River Delta system along with the Wax Lake Outlet Delta and the Mississippi River Delta are the only three areas in Louisiana where land is being gained. Beneficial use of dredge spoil from shipping channel maintenance is used on the Atchafalaya River Delta to supplement natural accretion. These dredge spoil islands have the ability to provide valuable nesting habitat for a variety of waterbirds, including Mottled Ducks. Previous studies on these islands reported mammalian predation to be a significant cause of nest failure for Mottled Ducks. I tested the hypothesis that predator reduction through trapping would increase Mottled …

A System Dynamics View Of The Acute Bed Blockage Problem In The Irish Healthcare System, Waleed Abo Hamad, Wael Rashwan, Amr Arisha

Articles

Global population ageing is creating immense pressures on hospitals and other healthcare services, compromising their abilities to meet the growing demand from elderly patients. Current demand–supply gaps result in prolonged waiting times in emergency departments (EDs), and several studies have focused on improving ED performance. However, the overcrowding in EDs generally stems from delayed patient flows to inpatient wards – which are congested with inpatients waiting for beds in post-acute facilities. This problem of bed blocking in acute hospitals causes substantial cost burdens on hospitals. This study presents a system dynamics methodology to model the dynamic flow of elderly patients …
