Furthering Women In Policing: How A Police Department's Duty Firearm Selection Process May Mitigate The Gender Disparity In Marksmanship, Jenna Prochnau

Honors Program: Senior Projects (Public)

Previous research has revealed that there are several benefits to increasing the representation of women in law enforcement, including less use of force, increased community trust, and better outcomes for domestic violence and sexual assault victims. While many police departments now recognize these benefits and are aiming to recruit more women, a problem persists because women are less likely to graduate from police academies than their male counterparts. A significant difference has been observed in the area of marksmanship, particularly, with more female recruits failing to meet firearm scoring standards. Currently, very little is known about how police departments select …

Assessing Pre-Literacy Behaviors In Infants And Toddlers: Psychometric Evaluation Of The Infant Toddler Literacy Assessment (Itla-3), Barbara J. Jackson, Christine Marvin, Amy J. Encinger, Nicole Buchholz, Becky Zessin

Department of Special Education and Communication Disorders: Faculty Publications

Assessment of emerging literacy in young children is generally limited to either skill development in children over 3 years of age or the quality and context of young children’s early literacy experiences. Although there has been promotion of their early literacy experiences, assessment of emerging pre-literacy behaviors in children younger than 3 years has yet to be organized into a single tool.

Preliminary work on the Infant Toddler Literacy Assessment (ITLA) has progressed through initial steps of scale development and shown promise as a criterionbased, standardized assessment for tracking children’s pre-literacy behaviors and guiding practitioners in supporting development of those …

Land Use Influences The Composition And Antimicrobial Effects Of Propolis, Amara J. Orth, Emma H. Curran, Eric J. Haas, Andrew C. Kraemer, Audrey M. Anderson, Nicholas J. Mason, Carol A. Fassbinder-Orth

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Honey bee propolis is a complex, resinous mixture created by bees using plant sources such as leaves, flowers, and bud exudates. This study characterized how cropland surrounding apiaries affects the chemical composition and antimicrobial effects of propolis. The chemical composition and compound abundance of the propolis samples were analyzed using Gas Chromatography- Mass Spectrometry (GC-MS) and the antimicrobial effects were analyzed using the 50% minimum inhibitory concentration (MIC₅₀) assay against four relevant bee pathogens, Serratia marcescens, Paenibacillus larvae, Lysinibacillus sphaericus, and Klebsiella pneumoniae. Propolis composition varied significantly with apiary, and cropland coverage predicted mean sum abundance of …

Taxonomic Changes Suggested By The Genomic Analysis Of Hesperiidae (Lepidoptera), Jing Zhang, Qian Cong, Jinhui Shen, Nick V. Grishin

Insecta Mundi

Our expanded efforts in genomic sequencing to cover additional skipper butterfly (Lepidoptera: Hesperiidae) species and populations, including primary type specimens, call for taxonomic changes to re­store monophyly and correct misidentifications by moving taxa between genera and proposing new names. Reconciliation between phenotypic characters and genomic trees suggests three new tribes, two new sub­tribes, 23 new genera, 17 new subgenera and 10 new species that are proposed here: Psolosini Grishin, new tribe (type genus Psolos Staudinger, 1889), Ismini Grishin, new tribe (type genus Isma Distant, 1886), Eetio­nini Grishin, new tribe (type genus Eetion de Nicéville, 1895), Orphina Grishin, new subtribe (type …

Synthesis And Evaluation Of 11c-Labeled Triazolones As Probes For Imaging Fatty Acid Synthase Expression By Positron Emission Tomography, James M. Kelly, Thomas M. Jeitner, Nicole N. Waterhouse, Wenchao Qu, Ethan J. Linstad, Banafshe Samani, Clarence Williams Jr., Anastasia Nikolopoulou, Alejandro Amor-Coarasa, Stephen G. Dimagno, John W. Babich

Department of Chemistry: Faculty Publications

Cancer cells require lipids to fulfill energetic, proliferative, and signaling requirements. Even though these cells can take up exogenous fatty acids, the majority exhibit a dependency on de novo fatty acid synthesis. Fatty acid synthase (FASN) is the rate-limiting enzyme in this process. Expression and activity of FASN is elevated in multiple cancers, where it correlates with disease progression and poor prognosis. These observations have sparked interest in developing methods of detecting FASN expression in vivo. One promising approach is the imaging of radiolabeled molecular probes targeting FASN by positron emission tomography (PET). However, although [¹¹C]acetate uptake by …

What Knowledge Do Early Childhood Teachers Use During Literacy Instruction? Using Stimulated Recall To Investigate An Unexplored Phenomenon, Rachel E. Schachter

Department of Child, Youth, and Family Studies: Faculty Publications

This study utilized a novel phenomenological approach with a stimulated recall procedure to understand the pedagogical reasoning of eight early child teachers during the enactment of literacy instruction in whole-group meeting and language arts activities. This approach to investigating knowledge—in contrast to more tra­ditional conceptualizations of knowledge—focused on knowledge use as a process and prioritized teachers’ perspectives on knowledge used to enact literacy instruc­tion in their own classrooms. Additionally, it allowed for a more nuanced investi­gation of the role of setting and teacher characteristics that are often examined in association with literacy instruction (e.g., degree attainment, years of experience, curriculum, …

Vaccinia Virus Arrests And Shifts The Cell Cycle, Caroline K. Martin, Jerzy Samolej, Annabel T. Olson, Cosetta Bertoli, Matthew S. Wiebe, Robertus A. M. De Bruin, Jason Mercer

School of Veterinary and Biomedical Sciences: Faculty Publications

Modulation of the host cell cycle is a common strategy used by viruses to create a proreplicative environment. To facilitate viral genome replication, vaccinia virus (VACV) has been reported to alter cell cycle regulation and trigger the host cell DNA damage response. However, the cellular factors and viral effectors that mediate these changes remain unknown. Here, we set out to investigate the effect of VACV infection on cell proliferation and host cell cycle progression. Using a subset of VACV mutants, we characterise the stage of infection required for inhibition of cell proliferation and define the viral effectors required to dysregulate …

Mobility Of Phosphine-Susceptible And -Resistant Rhyzopertha Dominica (Coleoptera: Bostrichidae) And Tribolium Castaneum (Coleoptera: Tenebrionidae) After Exposure To Controlled Release Materials With Existing And Novel Active Ingredients, Sabita Ranabhat, Kun Yan Zhu, Georgina Bingham, William R., Morrison Iii

Department of Entomology: Faculty Publications

There is interest in developing controlled release materials (CRMs) with novel modes of action to improve resistance management. Long-lasting insecticide-incorporated netting (LLIN) with deltamethrin has been effectively used against stored-product pests. Here, we evaluated the efficacy of different CRMs (LLIN or packaging) with each of four active ingredients (AI) (deltamethrin, permethrin, indoxacarb, and dinotefuran) and compared them to control CRMs in reducing movement and increasing mortality of phosphine-susceptible and -resistant Rhyzopertha dominica and Tribolium castaneum. Adults were exposed for 0.5, 2, or 60 min, and movement was assessed immediately or after 24, or 168 h using video-tracking and Ethovision …

Improving Taxonomic Delimitation Of Fungal Species In The Age Of Genomics And Phenomics, Asjley Stengel, Kimberly M. Stanke, Amanda C. Quattrone, Joshua Herr

Department of Plant Pathology: Faculty Publications

Species concepts have long provided a source of debate among biologists. These lively debates have been important for reaching consensus on how to communicate across scientific disciplines and for advancing innovative strategies to study evolution, population biology, ecology, natural history, and disease epidemiology. Species concepts are also important for evaluating variability and diversity among communities, understanding biogeographical distributions, and identifying causal agents of disease across animal and plant hosts. While there have been many attempts to address the concept of species in the fungi, there are several concepts that have made taxonomic delimitation especially challenging. In this review we discuss …

Fluids And Melts At The Magmatic-Hydrothermal Transition, Recorded By Unidirectional Solidification Textures At Saginaw Hill, Arizona, Usa, Wyatt M. Bain, Pilar Lecumberri-Sanchez, Erin E. Marsh, Matthew Steele-Macinnis

United States Geological Survey: Staff Publications

Fluid exsolution and melt evolution at the magmatic-hydrothermal transition are critical processes driving the metal enrichment of porphyry systems. Coeval fluid and melt inclusion assemblages in unidirectional solidification textures (USTs) at Saginaw Hill—a small, porphyry Cu system in southwestern Arizona—record a dynamic and repetitious process of fluid accumulation and release. The cores of quartz crystals throughout the UST bands host coeval silicate melt and brine inclusions but lack vapor-rich inclusions. This could indicate preferential expulsion of vapor and trapping of high-density brine during episodes of fracturing or the direct exsolution of single-phase high-salinity brine from the silicate melt. In contrast, …

Ten Nights' Dreams And Our Cat's Grave, Natsume Soseki

Zea E-Books Collection

Ten Nights’ Dreams (夢十夜, Yume Jūya) is a classic written work from the Japanese master Natsume Soseki. Originally published in 1908, it announced the emergence in Japanese literature of a modernist and impressionistic mode. Short ­vignettes with fantastic, tragic, or magical events convey an exquisite sensibility compounded with stark realism. Love, honor, duty, artistry, desire, despair, and regret all shape events in the dream-world. The stories themselves suggest echoes of meanings beyond the failures of rational sense-making. Ten dreams—each unique and arresting—form a panorama of life and feeling, at once universal and intensely present.

“Our Cat’s Grave” is a brief …

Post-Termination Effects Of Cover Crop Monocultures And Mixtures On Soil Inorganic Nitrogen And Microbial Communities On Two Organic Farms In Illinois, Eleanor E. Lucadamo, Ashley A. Holmes, Samuel E. Wortman, Anthony C. Yannarell

Department of Agronomy and Horticulture: Faculty Publications

Cover crops can continue to affect agricultural systems even after they have been terminated by influencing nitrogen dynamics and by altering soil microbial communities. These post-termination effects can influence soil fertility, weed pressure, and the dynamics of potential plant pathogens in the narrow window of time between cover crop termination and cash crop emergence. We evaluated the post-termination effects of 12 different spring-sown cover crop mixtures and monocultures on soil nitrogen and microbial communities on two different organic farms in Central Illinois (on Lawson silt loam soil) and Northern Illinois (on Virgil silt loam soil). In comparison to control plots …

Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley Lubben

Center for Agricultural Profitability

This report shows how the currently proposed policies differ; shows how these policies have aligned with historical market behavior; provides alternative specifications to regional minimums; and suggests policy alternatives to regional minimums.

The main purpose of this report is to show how current and potential alternative specifications of regional minimums would have historically aligned with observed market behavior. However, the fundamental question in the debate of the validity and effectiveness of regional minimums first rests on whether robust price discovery has historically occurred over time and within each USDA-AMS region. If there has been a lack of price discovery during …

Optimizing Management Of Invasions In An Uncertain World Using Dynamic Spatial Models, Kim M. Pepin, Amy J. Davis, Rebecca S. Epanchin-Niell, Andrew M. Gormley, Joslin L. Moore, Timothy J. Smyser, H. Bradley Shaffer, William L. Kendall, Katriona Shea, Michael C. Runge, Sophie Mckee

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal drives invasion dynamics of nonnative species and pathogens. Applying knowledge of dispersal to optimize the management of invasions can mean the difference between a failed and a successful control program and dramatically improve the return on investment of control efforts. A common approach to identifying optimal management solutions for invasions is to optimize dynamic spatial models that incorporate dispersal. Optimizing these spatial models can be very challenging because the interaction of time, space, and uncertainty rapidly amplifies the number of dimensions being considered. Addressing such problems requires advances in and the integration of techniques from multiple fields, including ecology, …

An Appeal In Favor Of That Class Of Americans Called Africans, Lydia Maria Child, Paul Royster (Editor)

Zea E-Books in American Studies

The roots of white supremacy lie in the institution of negro slavery. From the 15th through the 19th century, white Europeans trafficked in abducted and enslaved Africans and justified the practice with excuses that seemed somehow to reconcile the injustice with their professed Christianity. The United States was neither the first nor the last nation to abolish slavery, but its proclaimed principles of freedom and equality were made ironic by the nation’s reluctance to extend recognition to all Americans.

“Americans” is what Mrs. Child calls those fellow countrymen of African ancestry in 1833; citizenship and equality were what she advocated …

Transformation Of Major Peanut (Arachis Hypogaea) Stilbenoid Phytoalexins Caused By Selected Microorganisms, Victor S. Sobolev, Travis E. Walk, Renee S. Arias, Alicia N. Massa, Valerie A. Orner, Marshall C. Lamb

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The peanut plant accumulates defensive stilbenoid phytoalexins in response to the presence of soil fungi, which in turn produce phytoalexin-detoxifying enzymes for successfully invading the plant host. Aspergillus spp. are opportunistic pathogens that invade peanut seeds; most common fungal species often produce highly carcinogenic aflatoxins. The purpose of the present research was to evaluate the in vitro dynamics of peanut phytoalexin transformation/detoxification by important fungal species. This work revealed that in feeding experiments, Aspergillus spp. from section Flavi were capable of degrading the major peanut phytoalexin, arachidin-3, into its hydroxylated homolog, arachidin-1, and a benzenoid, SB-1. However, Aspergillus niger from …

A Precise Dispenser Design For Canine Cognition Research, Walker Arce, Jeffrey R. Stevens

Department of Electrical and Computer Engineering: Faculty Publications

Some forms of canine cognition research require a dispenser that can accurately dispense precise quantities of treats. When using off-the-shelf or retrofitted dispensers, there is no guarantee that a precise number of treats will be dispensed. Often, they will over-dispense treats, which may not be acceptable for some tasks. Here we describe a 3D-printed precise treat dispenser with a 59-treat capacity driven by a stepper motor drive and controlled by an integrated Raspberry Pi. The dispenser can be built for less than 200 USD and is fully 3D printable. While off-the-shelf dispensers can result in an error rate of 20–30%, …

School of Natural Resources: Faculty Publications

Allometric equations for calculation of tree above-ground biomass (AGB) form the basis for estimates of forest carbon storage and exchange with the atmosphere. While standard models exist to calculate forest biomass across the tropics, we lack a standardized tool for computing AGB across boreal and temperate regions that comprise the global extratropics. Here we present an integrated R package, allodb, containing systematically selected published allometric equations and proposed functions to compute AGB. The data component of the package is based on 701 woody species identified at 24 large Forest Global Earth Observatory (ForestGEO) forest dynamics plots representing a wide diversity …

The False Dichotomy Of Sex And Religion In America, Kelsy Burke

Department of Sociology: Faculty Publications

Religion and sexuality are polysemic categories. While conservative religion often fights against progressive sexual politics in contemporary America, this “usual story” is fractured and destabilized by people navigating the relationship between religion and sexuality as complex social creatures, not pundits or caricatures. Drawing from interdisciplinary scholarship, I examine salient issues of sexual politics—including abortion and reproductive rights, LGBT rights, and pornography—to show how religious actors have been on both sides of these debates. Because of this polysemic complexity, scholars of religion must not only tend to the dynamic interaction between religion and other categories, we must also recognize and study …

Drought Imprints On Crops Can Reduce Yield Loss: Nature's Insights For Food Security, Peng Fu, Deepak Jaiswal, Justin M. Mcgrath, Shaowen Wang, Stephen P. Long, Carl J. Bernacchi

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The Midwestern “Corn-Belt” in the United States is the most productive agricultural region on the planet despite being predominantly rainfed. In this region, global climate change is driving precipitation patterns toward wetter springs and drier mid- to late-summers, a trend that is likely to intensify in the future. The lack of precipitation can lead to crop water limitations that ultimately impact growth and yields. Young plants exposed to water stress will often invest more resources into their root systems, possibly priming the crop for any subsequent mid- or late-season drought. The trend toward wetter springs, however, suggests that opportunities for …

Water Insecurity, Water Borrowing, And Psychosocial Stress Among Daasanach Pastoralists In Northern Kenya, Leslie Ford, Hilary J. Bethancourt, Zane Swanson, Rosemary Nzunza, Amber Wutich, Alexandra Brewis, Sera Young, David Almeida, Matthew J. Douglass, Emmanuel K. Ndiema, David R. Braun, Herman Pontzer, Asher Y. Rosinger

School of Natural Resources: Faculty Publications

This article quantifies Daasanach water insecurity experiences in Northern Kenya, examines how water insecurity is associated with water borrowing and psychosocial stress, and evaluates if water borrowing mitigates the stress from water insecurity. Of 133 households interviewed in 7 communities, 95% were water insecure and 74.4% borrowed water three or more times in the prior month. Regression analyses demonstrate water borrowing frequency moderates the relationship between water insecurity and psychosocial stress. Only those who rarely or never borrowed water reported greater stress with higher water insecurity. The coping mechanism of water borrowing may help blunt water insecurity-related stress.

Department of Chemistry: Faculty Publications

Fluoride has become widely used in dentistry because of its effectiveness in caries control. However, evidence indicates that excessive intake interferes with the metabolic processes of different tissues. Thus, this study aimed to investigate the effects of long-term exposure to F on the parotid salivary gland of mice, from the analysis of oxidative, proteomic and genotoxic parameters.

The animals received deionized water containing 0, 10 or 50 mg/L of F, as sodium fluoride, for 60 days. After, parotid glands were collected for analysis of oxidative biochemistry, global proteomic profile, genotoxicity assessment and histopathological analyses.

The results revealed that exposure to …
