On Learning Psycholinguistics Tools For English-Based Creole Languages Using Social Media Data, Pei-Chi Lo, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

The Linguistic Inquiry and Word Count (LIWC) tool is a psycholinguistics tool that has been widely used in both psychology and sociology research, and the LIWC scores derived from user-generated content are known to be good features for personality prediction [1], [2]. LIWC, however, is language specific as it relies on counting the percentage of predefined dictionary words occurring in the content. For content written in English Creoles which are languages based on English, the original English LIWC may not perform optimally due to its lack of words which are only used in the English Creoles. In this paper, we …

The model was used to make predictions of a specific geometry that was manufactured, tested and compared against the model. 12 specimens were built and tested. In flexure, empirical data had a percent error with respect to the model ranging from 10.9 to 65.4% with one outlier at …

Rapid Separation Of Bacteria From Blood For Sepsis Diagnosis, Mahsa Alizadeh

Theses and Dissertations

Sepsis is a severe blood infection caused by bacteria entering the blood stream. Sepsis caused by antibiotic resistant bacteria is very dangerous with a high mortality rate. The current clinical diagnostic methods for sepsis require culturing the blood sample prior to other steps of the diagnosis procedure. Culturing the blood samples is a time-consuming step which increases the time required for the diagnostic procedure. Considering the fact that the mortality rate of the sepsis increases as time passes, it is essential to find methods for sepsis diagnosis that do not require culturing the samples. The first step of a new …

Theses and Dissertations

The 2010, moment magnitude 8.8 earthquake that occurred near Maule, Chile caused major damages to several piers in the Port of Coronel located approximately 160 kilometers (100 miles) to the South of the earthquake epicenter. One of the piers, the North Pier, experienced significant lateral spreading that was caused from liquefaction of the soils at the approach zone of the pier. Damages from lateral spreading and liquefaction effects consisted of sheet pile welding ruptures of the cross-support beams, stiffener buckling, pile displacements, pile rotations, and pier deck displacement. Researchers analyzed the North Pier after the earthquake and documented in detail …

Microenvironmental Forces Regulate Notch Signaling Through Integrins, Michael Allen Detweiler

Boise State University Theses and Dissertations

The extracellular microenvironment contributes significantly to a cell’s function and behavior. For instance, cell-cell interactions, cell-substrate interactions, and physical forces are all factors of the extracellular environment that can alter cellular behavior. Cells can receive these signals and forces through various membrane channels and receptors that transmit the signals from the extracellular to the intracellular space. Canonical Notch signaling is induced by ligand interactions with neighboring cells, but recent evidence has revealed that Notch signaling can occur through a variety of extracellular stimuli including hyperglycemia, hypoxia, multiple growth factors, fluid shear stress, and extracellular matrix (ECM) composition. Although Notch activation …

Physio-Chemical Degradation Of Concrete: A Ramification Of Coupled Freeze-Thaw And Sulfate Attack, Md Aminul Islam

Boise State University Theses and Dissertations

Concrete structures experience damage due to Sulfate Attack (SA) and Freeze-Thaw (F-T) in cold regions containing ample amount of sulfate species. The combined effect of SA and F-T is a multiscale multiphysics damaging process for cementitious materials involving complicated chemical reactions and phase transition inside concrete pores. This thesis is a compilation of two theoretical models describing the SA induced damage in an unsaturated cementitious medium and damage due to the combined effect of SA and F-T. The classical theory of phase change and a diffusion-reaction process is utilized in the development of the models. The validity of the proposed …

Military Working Dogs In The United States Armed Forces From World War I To Vietnam, Tristan J. Kelly

Boise State University Theses and Dissertations

At the beginning of World War I, the only military working dogs the United States owned were sled dogs. In comparison, European nations in World War I used canines as sentries, messengers, ambulance, and draft dogs. In 1942, members of the American public, created Dogs for Defense Inc. to help recruit dogs for military use. By the end of the Vietnam War, dogs no longer were donated by the American public for use, rather the American military owned the dogs they deployed.

This thesis examines the use of dogs by the American military from World War I to the Vietnam …

The Effects Of Teacher Background On How Teachers Assess Native-Like And Nonnative-Like Grammar Errors: An Eye-Tracking Study, Wesley Makoto Schramm

Theses and Dissertations

Studies have shown that composition and L2 writing teachers give different scores (Golombek, Weigle, Boldt, & Valsecchi, 2003) and focus on different features (Brown, 1991) when assessing student writing, which is assumed to be due to the differences in their background and training (Santos, 1992; Atkinson & Ramanathan, 1995). Error gravity is thought to be one reason why composition and L2 writing teachers give different scores (Rifkin & Roberts, 1995). Common methods for examining error gravity were to analyze scores and responses given by the raters and to have raters reflect on the rating process and analyze their responses. Only …

Toward Real-Time Flip Fluid Simulation Through Machine Learning Approximations, Javid Kennon Pack

Theses and Dissertations

Fluids in computer generated imagery can add an impressive amount of realism to a scene, but are particularly time-consuming to simulate. In an attempt to run fluid simulations in real-time, recent efforts have attempted to simulate fluids by using machine learning techniques to approximate the movement of fluids. We explore utilizing machine learning to simulate fluids while also integrating the Fluid-Implicit-Particle (FLIP) simulation method into machine learning fluid simulation approaches.

The Development Of A Reliable Change Index And Cutoff For The Score-15, Cara Ann Nebeker Adams

Theses and Dissertations

The Systemic Clinical Outcome and Routine Evaluation version 15 (SCORE-15) is an assessment used to assess for clinical change in family functioning. The SCORE-15 has been demonstrated in the past to be a reliable and valid measure for assessing for clinical change and is largely used throughout the UK. However, the SCORE-15 lacks the ability to determine whether an individual's change in family functioning is clinically significant. This study aims to establish a reliable change index and clinical cutoff score based on a US sample so that researchers and clinicians can determine clinically significant change. A sample of 63 clinical …

Innate Immune Cell Phenotypes Are Dictated By Distinct Epigenetic Reprogramming, Kevin Douglas Adams

Theses and Dissertations

The innate immune system is the first line of host defense against external exposures. During these initial encounters, antigen presenting cells - specifically monocytes and macrophages - modulate further inflammatory responses. Macrophages exist along a spectrum of phenotypic programs; on the inflammatory M1 end they enhance immune activity while on the anti-inflammatory M2 end they suppress further immune activation. Furthermore, within M2 macrophages there exist many subpopulations, namely M2a and M2d, each with specific roles during infection or exposure. We sought to compare the epigenetic profiles of these subpopulations of macrophages to determine key regulatory gene networks and factors that …

Pore Pressure Generation And Shear Modulus Degradation During Laminar Shear Box Testing With Prefabricated Vertical Drains, Landon Scott Kinney

Theses and Dissertations

Liquefaction is a costly phenomenon where soil shear modulus degrades as the generation of excess pore pressures begins. One of the methods to mitigate liquefaction, is the use of prefabricated vertical drains. Prefabricated vertical drains provide a drainage path to effectively mitigate the generation of pore pressures and aid in shear modulus recovery. The aims of this study were to define shear modulus degradation vs. shear strain as a function of excess pore pressure ratio; define the effects of prefabricated vertical drains on the behavior of pore pressure generation vs. shear strain; and to define volumetric strain as a function …

Bobcat Abundance And Habitat Selection On The Utah Test And Training Range, Kyle David Muncey

Theses and Dissertations

Remote cameras have become a popular tool for monitoring wildlife. We used remote cameras to estimate bobcat (Lynx rufus) population abundance on the Utah Test and Training Range during two sample periods between 2015 and 2017. We used two statistical methods, closed capture mark-recapture (CMR) and mark-resight Poisson log-normal (PNE), to estimate bobcat abundance within the study area. We used the maximum mean distance moved method (MMDM) to calculate the effective sample area for estimating density. Additionally, we captured bobcats and estimated home range using minimum convex polygon (MCP) and kernel density estimation (KDE) methods. Bobcat abundance on the UTTR …

Property Localization For Grain Boundary Diffusivity Via Inverse Problem Theory, Christian Kurniawan

Theses and Dissertations

The structure and spatial arrangement of grain boundaries strongly affect the properties of polycrystalline materials such as corrosion, creep, weldability, superconductivity, and diffusivity. However, constructing predictive grain boundary structure-property models is taxing, both experimentally and computationally due to the high dimensionality of the grain boundary character space. The purpose of this work is to develop an effective method to infer grain boundary structure-property models from measurement of the effective properties of polycrystals by utilizing the inverse problem theory. This study presents an idealized case in which structure-property models for grain boundary diffusivity are inferred from a noisy simulation. The method …

Does Theming Camp Experiences Lead To Greater Quality, Satisfaction, And Promotion?, Andrew Lacanienta, Gary Ellis, Allen Taggart, Jenny Wilder

Journal of Youth Development

Using themes (such as the Wild West or Survivor or Star Wars) in camp settings may enhance the quality of camp activities and youths’ overall camp experience. We evaluated the effect of theming camp experiences on the quality of subjective experiences of campers. Campers (N = 231) in 3 sessions of a residential 4-H camp participated in the study. One camp session was fully themed (all activities used tangible and intangible props, cues, and imaginary story contexts), a second was partially themed (intangible cues and stories only), and the third was not themed. Questionnaires measuring the quality of immediate subjective …

Camp And College Parallels: Crucibles For Transition-Linked Turning-Points, Lisa K.-P. Olsen, Gwynn Powell, Barry Garst, Robert Bixler

Journal of Youth Development

This conceptual paper explores how the system of experiences that children encounter in a traditional, residential summer camp setting parallel traditional, residential, college setting for first-year students. Camp is a complex system in the sphere of youth development programs (YDP) because of the expectation for rapid adjustment by the camper to a novel physical and social environment. Many YDPs have a moderate to high level of connection with the child’s normal life, defined as similar to school or home environments and the activities in which youth regularly participate. A traditional residential summer camp offers a different degree of novelty than …

Informing Youth Health And Well-Being Programs: A National 4-H Healthy Living Evaluation Study, Donna Peterson, Laura Downey, Joanne Leatherman

Journal of Youth Development

4-H Healthy Living programs address healthy eating; physical activity; social-emotional health and well-being; alcohol, tobacco, and other drug use prevention; and injury prevention. Using the Systematic Screening and Assessment Method, this paper identified 32 4-H Healthy Living programs across the nation ready for comprehensive outcome evaluation and/or national replication based on 6 criteria. Weaknesses in an additional 78 programs that did not meet the criteria were also identified. Programs that failed to meet the criteria did so primarily because they lacked a clearly delineated theory of change or appropriate evaluation. Implications for practice include ways to strengthen program planning and …

Methanogens, Plausible Extraterrestrial Life Forms On Mars, And Their Tolerance To Increasing Concentrations Of Illite Clay, Chandler Kern

Biological Sciences Undergraduate Honors Theses

Methanogens, some of Earth’s most primitive prokaryotic organisms, are candidates for possible life forms capable of inhabiting Mars. Specifically, four different species (Methanobacterium formicicum, Methanococcus maripaludis, Methanosarcina barkeri, Methanothermobacter wolfeii) were analyzed for their tolerance to the presence of illite clay. Illite is a crystalline mineral that has been identified from regions of Mars’s surface. Results indicated that all four species grew with some success in the illite at different concentrations. This experimentation with methanogens’ abilities to survive and reproduce in the presence of illite allows for a more accurate understanding of the potential capability of microbial …

The Effect Of The Zika Virus On Rna Stress Granule Components, Nina Williams

Biological Sciences

In recent years, Zika virus (ZIKV) has taken over mainstream media. It captivated the world with the images of microcephaly babies born to infected mothers and the appearance of Guillain-Barré syndrome emerging from infected adults. ZIKV is transmitted by the Aedes mosquito. This virus is composed of a single-stranded positive-sense RNA genome that belongs to the Flaviviridae family. Our long-term goal is to understand the mechanisms in which the virus subverts the host organism’s translation machinery by modulation of RNA stress granules (SGs). Stress granules are RNA-protein complexes found in the cytoplasm that form when the cell is exposed to …
