The Effects Of Fatigue On A Dual-Task Postural Control Measure, Allisha R. Guzdial

Online Theses and Dissertations

CONTEXT: Concussions are a major concern in sport and healthcare professionals are recognizing its profoundness in the impact it has on athletes. There may be limitations in the current approach to assessments among each individual evaluation involved; however, the combination of all three assessments adds to its strength and determining the overall understanding of the concussion and its effects. Any measure of assessment that connects underlying issues arising from concussion to help decrease long-term impairments by returning to play prematurely, risking further injury, is essential. The need for a dual-task assessment delivers an increased sensitivity to the assessment by combining …

Positive Solutions, Existence Of Smallest Eigenvalues, And Comparison Of Smallest Eigenvalues Of A Fourth Order Three Point Boundary Value Problem, Sarah Schulz King`

Online Theses and Dissertations

The existence of smallest positive eigenvalues is established for the linear differential equations $u^{(4)}+\lambda_{1} q(t)u=0$ and $u^{(4)}+\lambda_{2} r(t)u=0$, $0\leq t \leq 1$, with each satisfying the boundary conditions $u(0)=u'(p)=u''(1)=u'''(1)=0$ where $1-\frac{\sqrt{3}}{3}\le p < 1$. A comparison theorem for smallest positive eigenvalues is then obtained. Using the same theorems, we will extend the problem to the fifth order via the Green's Function and again via Substitution. Applying the comparison theorems and the properties of $u_0$-positive operators to determine the existence of smallest eigenvalues. The existence of these smallest eigenvalues is then applied to characterize extremal points of the differential equation $u^{(4)} + q(t)u = 0$ satisfying boundary conditions $u(0) = u'(p) = u''(b) = u'''(b)= 0$ where $1-\frac{

Through the research, the investigator expected to better identify the gaps between lower performing and higher performing elementary schools in the region. My research question was, A Case study of …

The Relationship Between Teacher Efficacy And Use Of Data To Inform Instruction In Two Turnaround Middle Schools, Peggy Conrad Petrilli

Online Theses and Dissertations

Schools across our county must ensure that an increasing percentage of students meet state-specified proficiency standards for the schools to be rated as making Adequate Yearly Progress (AYP). The longer a school fails to make AYP, the more severe are the corrective actions that must be undertaken.

This study looks at two turnaround middle schools in the western United States, which were determined to be among the lowest-performing five percent in their state. The turnaround model adopted by this school district is the transformational model of school turnaround. This model requires replacing at least 50% of the staff and principal, …

Analysis Of Amplitude And Slope Diffraction Coefficients, Mehmet Bariş Tabakcioğlu, Ahmet Cansiz

Turkish Journal of Physics

The diffraction mechanism is used for field prediction in both light and shadowed regions. Slope and amplitude diffraction coefficients are vital to predict the field strength at the receiver accurately. In this paper, amplitude and slope diffraction coefficients for one of the ray theoretical models, the slope uniform theory of diffraction with convex hull (S-UTD-CH) model, are analyzed. Moreover, diffraction coefficients are given for knife-edge and wedge structures.

Molecular Characterisation Of The Genus Papaver Section Oxytona Using Issr Markers, Tuğba Gürkök, Eli̇f Kaymak, Gülşen Boztepe, Mesut Koyuncu, İskender Parmaksiz

Turkish Journal of Botany

Papaver bracteatum Lindl., P. orientale L., and P. pseudo-orientale (Fedde) Medw., species of section Oxytona Bernh. in the genus Papaver L., are found widely in the native flora of Turkey. They are commercially important for their high alkaloid content. Because genus Papaver section Oxytona has similar morphological characters, it is not easy to distinguish these species. We used the inter-simple sequence repeat (ISSR) molecular marker system to determine the molecular characterisation of this section. In this study, 20 ISSR primers have been studied in 180 accessions collected from 5 different regions of Turkey. A total of 82 bands were obtained, …

Turkish Journal of Botany

In this study, we researched the main aquatic vegetation (AV) species and their orthophosphate and turbidity removal efficiencies in the Lower Kelkit Basin of Turkey. We chose an experimental area (1650 m^2) in the field and determined orthophosphate (mg/L) and turbidity (NTU) variables at the charging and discharging points between November 2005 and March 2006. We also applied an experimental design including 9 treatments and 3 replications in aquarium conditions. Orthophosphate (mg/L) contents of each aquarium were measured at 6 time periods (initial measurement and days 1, 4, 9, 16, and 25). Ceratophyllum demersum L., Cladophora glomerata (L.) Kützing, Lemna …

A Room Of One's Own? Accessory Dwelling Unit Reforms And Local Parochialism, Margaret F. Brinig, Nicole Stelle Garnett

Journal Articles

Over the past decade, a number of state and local governments have amended land use regulations to permit the accessory dwelling units (“ADUs”) on single-family lots. Measured by raw numbers of reforms, the campaign to secure legal reforms permitting ADUs appears to be a tremendous success. The question remains, however, whether these reforms overcome the well-documented land-use parochialism that has, for decades, represented a primary obstacle to increasing the supply of affordable housing. In order to understand more about their actual effects, this Article examines ADU reforms in a context which ought to predict a minimal level of local parochialism. …

Predictors Of The Number Of Under-Five Malnourished Children In Bangladesh: Application Of The Generalized Poisson Regression Model, Mohammad Mafijul Islam, Morshed Alam, Md Tariquzaman, Mohammad Alamgir Kabir, Rokhsona Pervin, Munni Begum, Md Mobarak Hossain Khan

Journal Articles: Biostatistics

BACKGROUND: Malnutrition is one of the principal causes of child mortality in developing countries including Bangladesh. According to our knowledge, most of the available studies, that addressed the issue of malnutrition among under-five children, considered the categorical (dichotomous/polychotomous) outcome variables and applied logistic regression (binary/multinomial) to find their predictors. In this study malnutrition variable (i.e. outcome) is defined as the number of under-five malnourished children in a family, which is a non-negative count variable. The purposes of the study are (i) to demonstrate the applicability of the generalized Poisson regression (GPR) model as an alternative of other statistical methods and …

Joint Entropy Of Continuously Differentiable Ultrasonic Waveforms, M S. Hughes, John E. Mccarthy, J N. Marsh, S A. Wickline

Mathematics Faculty Research

This study is based on an extension of the concept of joint entropy of two random variables to continuous functions, such as backscattered ultrasound. For two continuous random variables, X and Y, the joint probability density p(x,y) is ordinarily a continuous function of x and y that takes on values in a two dimensional region of the real plane. However, in the case where X=f(t) and Y=g(t) are both continuously differentiable functions, X and Y are concentrated exclusively on a curve, γ(t)=(f(t),g(t)), in the x,y plane. This concentration can only be represented using a mathematically "singular" object such as a …

Mathematical Modelling Of Internal Heat Recovery In Flash Tank Heat Exchanger Cascades, Andrei Korobeinikov, John E. Mccarthy, Emma Mooney, Krum Semkov, James Varghese

Mathematics Faculty Research

Flash tank evaporation combined with a condensing heat exchanger can be used when heat exchange is required between two streams and where at least one of these streams is difficult to handle (tends severely to scale, foul, causing blockages). To increase the efficiency of heat exchange, a cascade of these units in series can be used. Heat transfer relationships in such a cascade are very complex due to their interconnectivity, thus the impact of any changes proposed is difficult to predict. Moreover, the distribution of loads and driving forces in different stages and the number of designed stages faces tradeoffs …

Building A Taxonomy Of Litigation: Clusters Of Causes Of Action In Federal Complaints, Christina L. Boyd, David A. Hoffman, Zoran Obradovic, Kosta Ristovski

Scholarship@WashULaw

This project empirically explores civil litigation from its inception by examining the content of civil complaints. We utilize spectral cluster analysis on a newly compiled federal district court dataset of causes of action in complaints to illustrate the relationship of legal claims to one another, the broader composition of lawsuits in trial courts, and the breadth of pleading in individual complaints. Our results shed light not only on the networks of legal theories in civil litigation but also on how lawsuits are classified and the strategies that plaintiffs and their attorneys employ when commencing litigation. This approach permits us to …

Visual Analysis Of E-Textbooks For Senior High School In Indonesia, Ouda Ena

Dissertations

The purpose of the study was to evaluate the visual images used as illustrations in the English electronic textbooks for grades ten, eleven, and twelve in Indonesia. Qualitative visual content analysis was employed as the methodology of the research. The analysis focused on whether these e-textbooks accommodated the religious, gender, ethnic, and socioeconomic diversity of the students. These four aspects of cultural diversity that influenced students learning in Indonesian contexts were crucial to examine because the students were so diverse as results of the geographical conditions and historical background of Indonesia. Eight English e-textbooks were examined. First, the result showed …

Where Is Equal Protection? Applying Strict Scrutiny To Use Of Race By Law Enforcement, Evan Gerstmann

Political Science and International Relations Faculty Works

This article seeks to move the debate over the use of race by law enforcement beyond the current focus on racial profiling, arguing that the courts must apply strict scrutiny to all use of race by law enforcement, including the stopping and questioning of persons based on suspect descriptions that include race. The current debate implicitly (and sometimes explicitly) assumes that law enforcement’s use of race can be divided into unconstitutional racial profiling and all other uses of races, which are presumptively legitimate. However, when other institutions rely upon race, such as public universities implementing affirmative action programs, courts automatically …

Counting Links And Knots In Complete Graphs, Loren Abrams, Blake Mellor, Lowell Trott

Mathematics, Statistics and Data Science Faculty Works

We investigate the minimal number of links and knots in embeddings of complete partite graphs in S³. We provide exact values or bounds on the minimal number of links for all complete partite graphs with all but 4 vertices in one partition, or with 9 vertices in total. In particular, we find that the minimal number of links in an embedding of K_4,4,1 is 74. We also provide exact values or bounds on the minimal number of knots for all complete partite graphs with 8 vertices.

Congruence Classes Of 2-Adic Valuations Of Stirling Numbers Of The Second Kind, Curtis Bennett, Edward Mosteig

Mathematics, Statistics and Data Science Faculty Works

We analyze congruence classes of S(n,k), the Stirling numbers of the second kind, modulo powers of 2. This analysis provides insight into a conjecture posed by Amdeberhan, Manna and Moll, which those authors established for k at most 5. We provide a framework that can be used to justify the conjecture by computational means, which we then complete for values of k between 5 and 20.

Conformal Gravity And The Alcubierre Warp Drive Metric, Gabriele U. Varieschi, Zily Burstein

Physics Faculty Works

We present an analysis of the classic Alcubierre metric based on conformal gravity, rather than standard general relativity. The main characteristics of the resulting warp drive remain the same as in the original study by Alcubierre, that is, effective superluminal motion is a viable outcome of the metric. We show that for particular choices of the shaping function, the Alcubierre metric in the context of conformal gravity does not violate the weak energy condition, as was the case of the original solution. In particular, the resulting warp drive does not require the use of exotic matter. Therefore, if conformal gravity …

Self-Completeness And The Generalized Uncertainty Principle, Maximiliano Isi, Jonas Mureika, Piero Nicolini

Physics Faculty Works

The generalized uncertainty principle discloses a self-complete characteristic of gravity, namely the possibility of masking any curvature singularity behind an event horizon as a result of matter compression at the Planck scale. In this paper we extend the above reasoning in order to overcome some current limitations to the framework, including the absence of a consistent metric describing such Planck-scale black holes. We implement a minimum-size black hole in terms of the extremal configuration of a neutral non-rotating metric, which we derived by mimicking the effects of the generalized uncertainty principle via a short scale modified version of Einstein gravity. …

Making Education Work For Latinas In The U.S., Jongyeon Ee

School of Education Faculty Works

In California, almost 40% of European American adults hold a BA degree, as do 23% of African Americans and 48% of Asians. However, only 11% of adult Latinas/os hold a BA degree or higher. Given that the majority of the school age population in the state is now Latina/o, this undereducation is not just an urgent problem, but foreshadows economic disaster for California.
