The Effect Of Hydrostatic Pressure On Neuronal Cell Morphology In Vitro, Kallie Etten

All Theses

Traumatic brain injury (TBI) and subsequent rises in intracranial pressure (ICP) are associated with high mortality and has a number of physical and behavorial consequences to which the specific causes are unknown. We hypothesized that exposure of neuronal cells to elevated pressure can cause neurite retraction and / or apoptosis. Loss of communication between neurons due to these cellular-level events may play a part in complications seen in TBI patients, such as neurodegenerative diseases, increased anxiety, fear, depression, cognitive problems, as well as motor and visual deficits. In the present study, the effect of elevated hydrostatic pressure was evaluated at …

In The Kitchen, Amber Eckersley

All Theses

This series of work explores the fragmented nature of memory, investigates the dynamism of my grandma's kitchen, and subverts nostalgia typically associated with the South. Each image in the series represents a particular memory, set of memories, or fragment of memories from my childhood of planting, growing, and picking food with my grandma as well as preserving it and cooking it with her. The ordering and decision making of what fragments go in which image is imprecise. The imprecision is a reflection of how memory operates - fragmented, mutable, and fleeting. The markings on the pots, remnants of food processes, …

Resistance Against Futility In The Name Of Convenience, Dalia Karina Delanuez

All Theses

While utilizing plastics, my primary motivation as an artist is to understand how this material can disassociate the body from its natural environment and its subsequent effects. In my work, I speak of three spaces that are not distinct but that overlap each other. I analyzed my interaction with plastics as an intermediate space. This space of transition and domestic use is explained through sculpture in several modalities. My first sculpture is a fragmented installation. My second is a video projection of my body within a sculptural surface and a filmed documentation. My third sculpture is participatory and includes a …

A Tidy Data Model For Natural Language Processing Using Cleannlp, Taylor B. Arnold

Department of Math & Statistics Faculty Publications

Recent advances in natural language processing have produced libraries that extract low level features from a collection of raw texts. These features, known as annotations, are usually stored internally in hierarchical, tree-based data structures. This paper proposes a data model to represent annotations as a collection of normalized relational data tables optimized for exploratory data analysis and predictive modeling. The R package cleanNLP, which calls one of two state of the art NLP libraries (CoreNLP or spaCy), is presented as an implementation of this data model. It takes raw text as an input and returns a list of normalized tables. …

When University of Idaho (UI) Extension brought the Idaho 4-H Teen Conference to UI's main campus, the conference organizers collaborated with UI librarians to organize a workshop in the library's newly established makerspace, the Making, Innovating, and Learning Laboratory (MILL). In the MILL, the students used cutting-edge technology to foster new or existing interests in science, technology, engineering, and math (STEM). This article describes how Extension and 4-H youth development professionals can team with librarians to use library makerspaces to introduce 4-H high school students to STEM technologies and digital literacies that will be necessary for jobs of the future.

Perspective: Arabia Infelix: The War Devouring Yemen, Sheila Carapico

Political Science Faculty Publications

For many centuries, European cartographers labeled the southwest corner of the otherwise mostly desert Arabian Peninsula as Arabia Felix, or “Happy Arabia.” It was a place where towering mountains trapped clouds blown in from the Indian Ocean so that twice-annual monsoon rains blessed terraced slopes and lowland wadis with plentiful crops. Sadly, since fighting engulfed the country in late March 2015, Yemen has never been less felix.

Risk And Resilience In Health Data Infrastructure, W. Nicholson Price Ii

Articles

Today’s health system runs on data. However, for a system that generates and requires so much data, the health care system is surprisingly bad at maintaining, connecting, and using those data. In the easy cases of coordinated care and stationary patients, the system works—sometimes. But when care is fragmented, fragmented data often result. Fragmented data create risks both to individual patients and to the system. For patients, fragmentation creates risks in care based on incomplete or incorrect information, and may also lead to privacy risks from a patched together system. For the system, data fragmentation hinders efforts to improve efficiency …

Thermometry Of Bosonic Mixtures In Optical Lattices Via Demixing, F. Lingua, B. Capogrosso-Sansone, F. Minardi, V. Penna

Physics

Motivated by recent experiments and theoretical investigations on binary mixtures, we investigate the miscible-immiscible transition at finite temperature by means of Quantum Monte Carlo. Based on the observation that the segregated phase is strongly affected by temperature, we propose to use the degree of demixing for thermometry of a binary bosonic mixture trapped in an optical lattice. We show that the proposed method is especially sensitive at low temperatures, of the order of the tunnelling amplitude, and therefore is particularly suitable in the regime where quantum magnetism is expected.

The Z2 Toric-Code And The Double-Semion Topological Order Of Hardcore Bose-Hubbard-Type Models In The Strong-Interaction Limit, Wei Wang, Barbara Capogrosso-Sansone

Physics

We present a generic framework for the emergence of the {{\mathbb{Z}}}-{2} Z 2 toric-code and the double-semion topological order in a wide class of hardcore Bose-Hubbard-type models governed by density-density interaction and in the strong-interaction regime. We fix fractional filling factor and study under which conditions the density-density interaction gives rise to topological degeneracy. We further specify which dynamics determines the toric-code and the double-semion topological order. Our results indicate that the specifics of the density-density interaction determine the long-range entanglement of the model which possesses "restricted patterns" of the long-range entanglement realized in corresponding string-net models with the same …

The Montana Expression 2017: 2017’S Costly Fire Season, Jeremy L. Sage, Norma P. Nickerson

Institute for Tourism and Recreation Research Publications

Montana, along with many western states, experienced a severe fire season in the summer of 2017. According to the Northern Rockies Coordination Center (NRCC), fires consumed 1,276,456 acres of Montana lands. Nearly half of these lands are U.S. Forest Service owned (Table 1). The severity of the fire season led Montana’s Governor, Steve Bullock, to declare a state of emergency at the beginning of September. At this time, the state had already exceeded the $30 million in its firefighting fund by $14.5 million.1 The NRCC estimates the total costs of fighting Montana’s wildfires topped $390 million.2 The combination of extreme …

The robustness of trading result will be implemented by using stationary bootstrap approach. From the result, we can see the trading strategy based on cointegration relationship analysis is efficient to set up trading strategies in given datasets.

A Molecular Diagnostic Survey Of Pathogens And Parasites Of Honey Bees, Apis Mellifera L., From Arkansas And Oklahoma, Dylan Cleary

Graduate Theses and Dissertations

The health and viability of colonies of the honey bee, Apis mellifera, in the United States have fluctuated dramatically over the past decade. This poses a substantial threat to agricultural production in this country. Currently, no single factor has been identified for this decline. Rather, it has been suggested that the interaction between multiple biotic and abiotic stressors may be responsible. Among these factors are pesticides, habitat loss, climate and weather, parasites and pathogens, and colony management techniques. For this reason, it is important to examine the prevalence of honey bee parasite and pathogen infection at the state level in …

However, the use of electro spun nanofibers in metal ion adsorption is emerging and comparatively innovative. Nanofiber materials hold great potential in advancing the growth of metallurgical technologies and progress for the separation of metallic ions from various sources. The Physico-chemical removal processes of adsorption use nanofibers due to their large surface area to volume ratio and the availability of a wide variety of …

Nematic Topological Superconducting Phase In Nb-Doped Bi₂Se₃, Junying Shen, Wen-Yu He, Noah Fan Qi Yuan, Zengle Huang, Chang-Woo Cho, Seng Huat Lee, Yew San Hor, Kam Tuen Law, Rolf Lortz

Physics Faculty Research & Creative Works

A nematic topological superconductor has an order parameter symmetry, which spontaneously breaks the crystalline symmetry in its superconducting state. This state can be observed, for example, by thermodynamic or upper critical field experiments in which a magnetic field is rotated with respect to the crystalline axes. The corresponding physical quantity then directly reflects the symmetry of the order parameter. We present a study on the superconducting upper critical field of the Nb-doped topological insulator Nb_xBi₂Se₃ for various magnetic field orientations parallel and perpendicular to the basal plane of the Bi₂Se₃ layers. The …

Preschool Executive Function Predicts Childhood Resting State Functional Connectivity And Adhd And Depression, Elizabeth Hawkey

Arts & Sciences Graduate Student Theses and Dissertations

Background: Measures of executive function (EF), such as the Behavior Rating Inventory of Executive Function, distinguish children with Attention-Deficit/Hyperactivity Disorder (ADHD) from control children, but less work has examined relationships to depression or brain network organization. This study examined whether early childhood EF predicted a new onset or worsening of ADHD and/or depression, and examined how early childhood EF related to functional connectivity of brain networks at school age. Methods: Participants were 247 children, enrolled at ages 3-6, from a prospective study of emotion development. The BRIEF Global Executive Composite (BRIEF-GEC) was used as the measure of EF in early …

The Impact Of Delay On Retrieval Success In The Parietal Memory Network, Nathan Anderson

Arts & Sciences Graduate Student Theses and Dissertations

Recent work has identified a Parietal Memory Network (PMN), which exhibits regular patterns of activation during memory encoding and retrieval. Among these characteristic patterns, this network displays a strong “retrieval success” effect, showing greater activation for correctlyremembered studied items (hits) compared to correctly-rejected novel items (CRs). To date, most relevant studies have used short retention intervals. Here, we ask if the retrieval success effect seen in the PMN would remain consistent over a delay. Twenty participants underwent fMRI while encoding and recognizing scenes. Greater activity for hits than for correctly-rejected lures within PMN regions was observed after a short delay …

Do Learners Have Insight Into The Levels Of Processing Effect? Exploring Unresolved Levels Of Processing Phenomena With Judgments Of Learning, Elif Eylul Tekin

Arts & Sciences Graduate Student Theses and Dissertations

The levels of processing (LOP) effect shows that semantic processing leads to better retention than other types of processing. The effect is routinely obtained on many types of tests, yet, to this day, its mechanisms are still debated and it is poorly understood. In two old/new recognition experiments, I investigated potential explanations as to why the LOP effect occurs under intentional learning instructions. I asked a) whether subjects were aware of the LOP effect while they were studying the material, b) whether explicitly encouraging subjects to study the words with their idiosyncratic strategies would eliminate the effect, and c) whether …

How Does Increasing The Power Of Retrieval Cues Change The Experience Of Remembering?, Oyku Uner

Arts & Sciences Graduate Student Theses and Dissertations

Increasing the power of retrieval cues typically enhances recall and recognition. Is this driven by remembering, knowing, or both? The current study used the remember/know paradigm in different recall tasks that manipulated the power of retrieval cues. In the first two experiments, participants studied words in a semantic or phonetic context, and were tested in one of these contexts, resulting in two match and two mismatch conditions. Participants recalled more in the match conditions, and this was driven by remembering. In the third experiment, participants studied multiple word lists and were tested immediately after each list with varying number of …

Going Beyond ‘Do No Harm’: A Critical Annotation, Robert F. Johnson

Peer Reviewed Articles

The Op-Ed article in the New York Times (November 4th, 2016), “On Assisted Suicide, Going Beyond Do No Harm” by Haider Javed Warraich provided an articulate and timely plea for more widespread availability and application of physician-assisted dying, or “suicide”, as part of end-of-life medical care. While this profound intervention should be considered by physicians and others as an option for those able to express their wishes at the end-of-life, it must be considered in the context of the ethical principles appropriate for all health care interventions and recognized for its limited role in the overall approach to compassionate care …

Universal Design: Stop Banning Laptops!, Ruth Colker

Cardozo Law Review

The article argues that banning laptops in university classrooms, particularly in law schools, is unnecessary and counterproductive. The author advocates for a permissive laptop policy as part of Universal Design principles, which aim to create inclusive learning environments. While acknowledging concerns about distractions and note-taking effectiveness, the author presents empirical data suggesting that laptop use does not harm academic performance and can benefit students with disabilities without stigmatizing them.
