Comparison Of Some Suggested Estimators Based On Differencing Technique In The Partial Linear Model Using Simulation, Saja Mohammad Hussein

Baghdad Science Journal

In this paper new methods were presented based on technique of differences which is the difference- based modified jackknifed generalized ridge regression estimator(DMJGR) and difference-based generalized jackknifed ridge regression estimator(DGJR), in estimating the parameters of linear part of the partially linear model. As for the nonlinear part represented by the nonparametric function, it was estimated using Nadaraya Watson smoother. The partially linear model was compared using these proposed methods with other estimators based on differencing technique through the MSE comparison criterion in simulation study.

Time For Change: Stepping Up The Fda's Regulation Of Dietary Supplements To Promote Consumer Safety And Awareness, George Kennett

Journal of Law and Health

People are often looking for that quick fix when it comes to their health. With dietary supplements so readily available on the market, the public assume that they have been through rigorous testing. Dietary supplements are not tested as much as consumers believe. The Food and Drug Administration (FDA) does not initiate the same type of testing and analysis for supplements as it does for food, drink and medication. Given that people are now choosing supplemental meal replacements and the like, as opposed to whole foods, regulations drastically need to be stepped up in an effort to emphasise public safety. …

Parens Patriae And Parental Rights: When Should The State Override Parental Medical Decisions?, Elchanan G. Stern

Journal of Law and Health

Alfie Evans was a terminally ill British child whose parents, clinging to hope, were desperately trying to save his life. Hospital authorities disagreed and petitioned the court to enjoin the parents from removing him and taking him elsewhere for treatment. The court stepped in and compelled the hospital to discontinue life support and claimed that further treatment was not in the child’s best interest. This note discusses the heartbreaking stories of Alfie and two other children whose parents’ medical decisions on their behalf were overridden by the court. It argues that courts should never decide that death is in a …

Ancestral Pueblo Pottery: Cataloguing, Curation, Mount-Making And More, Elizabeth Jennings

Undergraduate Honors Theses

Ancestral Pueblo pottery is some of the most renowned pottery of its kind in North America, yet outside of the archaeology and art history communities its beauty and complexity is not well known. The University of Northern Colorado has a vast and remarkable collection of artifacts, predominately comprised of Native American pottery and ceramics. This collection was not previously widely accessible, partially because it was not published. The purpose of my research was to create an exhibition highlighting this collection of Ancestral Pueblo pottery in Michener Library at University of Northern Colorado, as well as an interactive touch screen kiosk …

Student Motivation In Education: An Intervention In Real-Time, Maddison North

Undergraduate Honors Theses

Motivation and academic performance have been shown to be linked, so improvement in academic motivation or factors that influence it may have the potential to improve academic performance. Academic motivation can fluctuate over a semester or even throughout a day. Even with these fluctuations, some students have the skills to remain motivated to study, attend class, and complete assignments. Yet, some do not, thus, strategies to help these students maintain motivation throughout the semester can have benefits for academic success. The main objective of this study was to understand whether a mobile intervention could be utilized to increase students’ academic …

The Existing Intersectionality Of Gender And Race Differences In Science, Technology, Engineering And Math Fields, Rachael Carrillo

Undergraduate Honors Theses

This thesis will examine the gender differences women and men experience in Science, Technology, Engineering and Math fields (STEM) in undergraduate education focusing on the binary genders--men and women--and their experiences in STEM. Thus, the research question is: Do undergraduate women in STEM experience higher levels of gender differences compared to men in STEM? This is an important research question because if female undergraduates in STEM are experiencing sexism while their male colleagues are not, this phenomenon may create a large issue of inequalities for women in our society. STEM fields are typically higher paying fields and if women are …

Examining The Educational Experiences Of Community Day School Graduates: A Narrative Inquiry, Willie J. Jones Iii

Electronic Theses, Projects, and Dissertations

Community day school graduates enter society with decisions about college, career, and work. Community day schools operate as a non-traditional education system that provides a separate and often unique education to many disenfranchised students, with lessened accountability protocols to assess whether these systems prepare graduates for life after high school. The number of community day schools and enrollment is declining, due in part to excessive changes within the law and stricter guidelines required to be met.

Patch Size As A Niche Dimension: Aquatic Insects Behaviorally Partition Enemy-Free Space Across Gradients Of Patch Size, William J. Resetarits, Matthew R. Pintar, Jason R. Bohenek, Tyler M. Breech

Faculty and Student Publications

© 2019 by University of Chicago. Positive correlation of species richness with area is ubiquitous in nature, but the processes driving that relationship, as well as those constraining typical patterns, remain elusive. Patch size variation is pervasive in natural systems, and it is thus critical to understand how variation in patch size, as well as its potential interaction with factors like predation and isolation, affects community assembly. We crossed patch quality (fish presence/absence) with patch size to the examine effects of quality, size, and their interaction on colonization by aquatic insects. Overall, beetles favored small, fishless patches, but individual species …

Testing Isomorphism Of Graded Algebras, Peter A. Brooksbank, James B. Wilson, Eamonn A. O'Brien

Faculty Journal Articles

We present a new algorithm to decide isomorphism between finite graded algebras. For a broad class of nilpotent Lie algebras, we demonstrate that it runs in time polynomial in the order of the input algebras. We introduce heuristics that often dramatically improve the performance of the algorithm and report on an implementation in Magma.

A Novel Switch-Like Function Of Delta-Catenin In Dendrite Development, Ryan Baumert

Dissertations and Theses (Open Access)

The formation of neuronal networks in the brain is tightly regulated, and dependent on the morphology of dendrites, the branch-like signal-receiving structures extending from neurons. Disruptions in dendrite development, or dendritogenesis, can lead to the atypical neuronal connectivity associated with multiple neurodevelopmental diseases. My research addresses molecular processes that underlie dendritogenesis via analysis of a pair of novel interactions involving the protein delta-catenin.

In neurons, delta-catenin localizes to dendrites and synapses, where it functions in their development and maintenance. Structurally, delta-catenin possesses a central Armadillo domain and a C-terminal PDZ-binding motif. This motif associates with PDZ domain-containing proteins, and is …

Machine Learning Predictions Electronic Couplings For Charge Transport Calculations Of P3ht, Evan D. Miller, Matthew L. Jones, Mike M. Henry, Bryan Stanfill, Eric Jankowski

Materials Science and Engineering Faculty Publications and Presentations

The purpose of this work is to lower the computational cost of predicting charge mobilities in organic semiconductors, which will benefit the screening of candidates for inexpensive solar power generation. We characterize efforts to minimize the number of expensive quantum chemical calculations we perform by training machines to predict electronic couplings between monomers of poly-(3-hexylthiophene). We test five machine learning techniques and identify random forests as the most accurate, information-dense, and easy-to-implement approach for this problem, achieving mean-absolute-error of 0.02 [× 1.6 × 10⁻¹⁹ J], R² = 0.986, predicting electronic couplings 390 times faster than quantum chemical calculations, …

Oxidation Behavior Of Welded Zry-3, Zry-4, And Zr–1nb Tubes, Jordan Vandegrift, Clemente J. Parga, Ben Coryell, Darryl P. Butt, Brian J. Jaques

Materials Science and Engineering Faculty Publications and Presentations

The Transient Reactor Test (TREAT) facility is a research reactor designed to simulate rapid transients to test new fuel designs. TREAT's cladding is exposed to unique conditions compared to normal water reactors. These conditions include: exposure to air at high temperatures (≥600 °C), rapid heating (≈700 °^C/_s), and cladding geometry that includes chamfers and welds. This work investigates the effects of chamfering and welding on the oxidation behavior of zirconium alloys (Zircaloy-3, Zircaloy-4, and Zr–1Nb). Tube specimens were examined under isothermal and transient conditions in dry and humid air. The effect of weld type (tungsten inert …

Stability Through Economic Growth In Afghanistan, Abdul Qadir Khan

Boise State University Theses and Dissertations

This thesis analyzes the Afghan public’s opinion to identify the overall direction of the country, whether the country, in terms of economic growth, is moving in a positive direction or not. How do economic factors affect the public’s views on the direction of the country? Based on that, this study finds that economic growth has an effect on the Afghan public’s opinion on the country’s direction.

Afghans are not enjoying stability in their country yet, after the majority of Afghans accepted U.S. military intervention in 2001 and the establishment of the new government to end instability. It was not an …
