Analyses Of Crime Patterns In Nibrs Data Based On A Novel Graph Theory Clustering Method: Virginia As A Case Study, Peixin Zhao, Majorie Darrah, Jim Nolan, Cun-Quan Zhang Jan 2014

Analyses Of Crime Patterns In Nibrs Data Based On A Novel Graph Theory Clustering Method: Virginia As A Case Study, Peixin Zhao, Majorie Darrah, Jim Nolan, Cun-Quan Zhang

Faculty & Staff Scholarship

This paper suggests a novel clustering method for analyzing the National Incident-Based Reporting System (NIBRS) data, which include the determination of correlation of different crime types, the development of a likelihood index for crimes to occur in a jurisdiction, and the clustering of jurisdictions based on crime type. The method was tested by using the 2005 assault data from 121 jurisdictions in Virginia as a test case. The analyses of these data show that some different crime types are correlated and some different crime parameters are correlated with different crime types. The analyses also show that certain jurisdictions within Virginia …

Linear and nonlinear crown variable functions for 173 Brutian pine (Pinus brutia Ten.) trees were incorporated into a well-known compatible volume and taper equation to evaluate their effect in model prediction accuracy. In addition, the same crown variables were also incorporated into three neural network (NN) types (Back-Propagation, Levenberg-Marquardt and Generalized Regression Neural Networks) to investigate their applicability in over-bark diameter and stem volume predictions. The inclusion of crown ratio and crown ratio with crown length variables resulted in a significant reduction of model sum of squared error, for all models. The incorporation of the crown variables to these …

Research in the deep terrestrial biosphere is driven by interest in novel biodiversity and metabolisms, biogeochemical cycling, and the impact of human activities on this ecosystem. As this interest continues to grow, it is important to ensure that when subsurface investigations are proposed, materials recovered from the subsurface are sampled and preserved in an appropriate manner to limit contamination and ensure preservation of accurate microbial, geochemical, and mineralogical signatures. On February 20th, 2014, a workshop on “Trends and Future Challenges in Sampling The Deep Subsurface” was coordinated in Columbus, Ohio by The Ohio State University and West Virginia University faculty, …

Widespread use of the chlorotriazine herbicide, atrazine, has led to serious environmental and human health consequences. Current methods of detecting atrazine contamination are neither rapid nor cost-effective. In this work, atrazine-specific single-stranded DNA (ssDNA) molecular recognition elements (MRE) were isolated. We utilized a stringent Systematic Evolution of Ligands by Exponential Enrichment (SELEX) methodology that placed the greatest emphasis on what the MRE should not bind to. After twelve rounds of SELEX, an atrazine-specific MRE with high affinity was obtained. The equilibrium dissociation constant (Kd) of the ssDNA sequence is 0.62 ± 0.21 nM. It also has significant selectivity …

Density-Dependent Regulation Of Brook Trout Population Dynamics Along A Core-Periphery Distribution Gradient In A Central Appalachian Watershed, Brock M. Huntsman, J Todd Petty Jan 2014

Density-Dependent Regulation Of Brook Trout Population Dynamics Along A Core-Periphery Distribution Gradient In A Central Appalachian Watershed, Brock M. Huntsman, J Todd Petty

Faculty & Staff Scholarship

Spatial population models predict strong density-dependence and relatively stable population dynamics near the core of a species' distribution with increasing variance and importance of density-independent processes operating towards the population periphery. Using a 10-year data set and an information-theoretic approach, we tested a series of candidate models considering density-dependent and density-independent controls on brook trout population dynamics across a core-periphery distribution gradient within a central Appalachian watershed. We sampled seven sub-populations with study sites ranging in drainage area from 1.3–60 km2and long-term average densities ranging from 0.335–0.006 trout/m. Modeled response variables included per capita population growth rate of young-of-the-year, adult, …

We report results from simulations in general relativity of magnetized disks accreting onto merging black hole binaries, starting from relaxed disk initial data. The simulations feature an effective, rapid radiative cooling scheme as a limiting case of future treatments with radiative transfer. Here we evolve the systems after binary-disk decoupling through inspiral and merger, and analyze the dependence on the binary mass ratio with $q\equiv m_{\rm bh}/M_{\rm BH}=1,1/2,$ and $1/4$. We find that the luminosity associated with local cooling is larger than the luminosity associated with matter kinetic outflows, while the electromagnetic (Poynting) luminosity associated with bulk transport of magnetic …

Genetic basis of phenotypic differences in individuals is an important area in biology and personalized medicine. Analysis of divergent Saccharomyces cerevisiae strains grown under different conditions revealed extensive variation in response to both drugs (e.g., 4-nitroquinoline 1-oxide [4NQO]) and different carbon sources. Differences in 4NQO resistance were due to amino acid variation in the transcription factor Yrr1. Yrr1YJM789 conferred 4NQO resistance but caused slower growth on glycerol, and vice versa with Yrr1S96, indicating that alleles of Yrr1 confer distinct phenotypes. The binding targets of Yrr1 alleles from diverse yeast strains varied considerably among different strains grown under the same conditions …

We report the first experimental observation of extreme multistability in a controlled laboratory investigation. Extreme multistability arises when infinitely many attractors coexist for the same set of system parameters. The behavior was predicted earlier on theoretical grounds, supported by numerical studies of models of two coupled identical or nearly identical systems. We construct and couple two analog circuits based on a modified coupled Rössler system and demonstrate the occurrence of extreme multistability through a controlled switching to different attractor states purely through a change in initial conditions for a fixed set of system parameters. Numerical studies of the coupled model …

Inhibition of phosphodiesterase-4 (PDE4), an enzyme that specifically hydrolyzes cyclic adenosine monophosphate (cAMP) increases intracellular cAMP/cAMP-response element binding protein (CREB) signaling. Activation of this signaling is considered as an important compensatory response that decreases motivational properties of drugs of abuse. However, it is not known whether PDE4 is involved in heroin seeking. Self-administration of heroin (50

Comparing The Acute Effects Of Elastic Resistance Bands On Kinetics And Kinematics During The Bench Press Exercise, Blake Baxter Jan 2014

Comparing The Acute Effects Of Elastic Resistance Bands On Kinetics And Kinematics During The Bench Press Exercise, Blake Baxter

EWU Masters Thesis Collection

"Elastic resistance training is becoming very popular in the strength and conditioning realm and is used at the collegiate and professional levels for various sports. Elastic resistance training has been shown to increase the force, velocity, and power compared to traditional free weight movements. The purpose of this study was to determine if a specific loading condition could increase both kinetic and kinematic variables within a bench press. To test this, two loading conditions (15% and 25% of 1RM) were used and each resistance load was added to a base of 60% of 1RM free weights. Twelve recreationally trained male …

An Exploration Of Mutation Effect Sizes In The Nematode Caenorhabditis Elegans, Melody Dossey Jan 2014

An Exploration Of Mutation Effect Sizes In The Nematode Caenorhabditis Elegans, Melody Dossey

EWU Masters Thesis Collection

Mutation rates vary within and among species, in part reflecting the variable input of the two main sources of mutation, DNA replication errors and DNA damage. In somatic tissues, oxidative damage resulting from free radical attacks on DNA is an important and well-characterized cause of mutation, contributing to many diseases and to the aging process. In contrast, it is not known whether oxidative damage can lead to heritable mutations in germline (sperm and egg) DNA. In a previous study, the germline mutation rate was estimated from a mutation accumulation study in two strains of rhabditid nematode (Caenorhabditis elegans), the N2 …

Mining Multi-Granular Multivariate Medical Measurements, Conrad Sykes Jan 2014

Mining Multi-Granular Multivariate Medical Measurements, Conrad Sykes

EWU Masters Thesis Collection

This thesis is motivated by the need to predict the mortality of patients in the Intensive Care Unit. The heart of this problem revolves around being able to accurately classify multivariate, multi-granular time series patient data. The approach ultimately taken in this thesis involves using Z-Score normalization to make variables comparable, Single Value Decomposition to reduce the number of features, and a Support Vector Machine to classify patient tuples. This approach proves to outperform other classification models such as k-Nearest Neighbor and demonstrates that SVM is a viable model for this project. The hope is that going forward other work …

The Relationship Between Simple Pleasures And Trait Gratitude, Megan Shupe

EWU Masters Thesis Collection

Grateful disposition is associated with positive affect, happiness, high levels of overall well-being and an appreciation of simple pleasures. This study further examined the relationship between simple pleasures and trait gratitude. I hypothesized that people with higher trait gratitude scores would notice more simple pleasures in their lives and feel more gratitude for simple pleasures than less grateful people. I acquired data from 169 undergraduate students at Eastern Washington University. Results suggested that grateful people experienced the same number of simple pleasures as less grateful people but were more grateful for them. This suggests that although grateful people do not …

Examining Sexual Satisfaction And Pretending Orgasm, Chelsea Twiss

EWU Masters Thesis Collection

An article in popular women’s magazine, Cosmopolitan, recently revealed a startling admission from its readers: 86% of respondents reported pretending orgasm during intercourse with a partner (Kylstra, 2011). Despite its apparent frequency, there is yet to be a study conducted investigating the relationship between pretending orgasm and overall sexual satisfaction (Ippolito, 2012). Sexual satisfaction is linked with important facets of life such as overall relationship satisfaction and general wellbeing. The present study examines the relationship between experiencing orgasm, pretending orgasm and overall sexual satisfaction. Participants were Eastern Washington University college students recruited via an online survey website (Qualtrics), and who …

Microcosm: Bachelor Of Fine Arts, Painting, Lauren Banquer

Honors Theses

Microcosm is the amalgamation of my interests in biology, chemistry, and art. I am inspired by my collection of objects from nature, particularly my entomological collection, and use the inherent shapes and patterns to create abstracted images drawing exclusively from life renderings, observations, and scientific research. Using a variety of different textures and techniques, mainly encaustic medium, I explore different applications of this medium to represent a sense of the object that I observe while painting. By painting on small wooden panels, I hope to recreate a sense of my small, intimate objects while also keeping a natural feel. Each …
