West Nile virus(WNV) is a globally distributed mosquito-borne virus of great public health concern. The number of WNV human cases and mosquito infection patterns vary in space and time. Many statistical models have been developed to understand and predict WNV geographic and temporal dynamics. However, these modeling efforts have been disjointed with little model comparison and inconsistent validation. In this paper, we describe a framework to unify and standardize WNV modeling efforts nationwide. WNV risk, detection, or warning models for this review were solicited from active research groups working in different regions of the United States. A total of 13 …

Aberrant activation of the nucleotide-binding domain and leucine-rich repeat related (NLR) family, pyrin domain containing 3 (NLRP3) inflammasome drives the development of many complex inflammatory diseases, such as obesity, Alzheimer’s disease, and atherosclerosis. However, no medications specifically targeting the NLRP3 inflammasome have become clinically available. Therefore, we aim to identify new inhibitors of the NLRP3 inflammasome in this study. Methods: Vesicle-like nanoparticles (VLNs) were extracted from garlic chives and other Allium vegetables and their effects on the NLRP3 inflammasome were evaluated in primary macrophages. After garlic chive-derived VLNs (GC-VLNs) were found to exhibit potent anti-NLRP3 inflammasome activity in cell culture, …

Multi-Feature Data Repository Development And Analytics For Image Cosegmentation In High-Throughput Plant Phenotyping, Rubi Quiñones, Francisco Munoz-Arriola, Sruti Das Choudhury, Ashok Samal

School of Computing: Faculty Publications

Cosegmentation is a newly emerging computer vision technique used to segment an object from the background by processing multiple images at the same time. Traditional plant phenotyping analysis uses thresholding segmentation methods which result in high segmentation accuracy. Although there are proposed machine learning and deep learning algorithms for plant segmentation, predictions rely on the specific features being present in the training set. The need for a multi-featured dataset and analytics for cosegmentation becomes critical to better understand and predict plants’ responses to the environment. High-throughput phenotyping produces an abundance of data that can be leveraged to improve segmentation accuracy …

Nguyen, Ankita Naithani, Daniel Hurley, Li Bai, Farid El Garch, Frédérique Woehrlé, Christine Miossec, Benjamin Roques, Peadar O’Gaora, James L. Bono, Séamus Fanning

Roman L. Hruska U.S. Meat Animal Research Center: Reports

An antibiotic susceptibility monitoring programme was conducted from 2004 to 2010, re-sulting in a collection of 143 Escherichia coli cultured from bovine faecal samples (diarrhoea) and milk‐aliquots (mastitis). The isolates were subjected to whole‐genome sequencing and were distrib-uted in phylogroups A, B1, B2, C, D, E, and G with no correlation for particular genotypes with pathotypes. In fact, the population structure showed that the strains belonging to the different phy-logroups matched broadly to ST complexes; however, the isolates are randomly associated with the diseases, highlighting the necessity to investigate the virulence factors more accurately in order to identify the mechanisms …

Conversational Style In Training, Megan Paul

Umbrella Summaries

What is conversational style?

Conversational style refers to a combination of stylistic strategies to personalize instructional text (oral or written) for learners. These include “the use of first and second rather than third person, directly addressing the reader, revealing [the author’s] personal beliefs, and/or using polite forms of address” (Ginns et al., 2013, p. 452). The following excerpts illustrate such styles:

“During inhaling, the [your] diaphragm moves down creating more space for the [your] lungs” (Mayer et al., 2004)

“Let me tell you what happens when lightning forms” (vs. just the scientific description; Moreno & Mayer, 2000)

Data Segmentation (Video), Quality Improvement Center For Workforce Development

Workforce Analytics Resources

Data segmentation is the process of breaking down “big” data into smaller, more meaningful groups, called segments. In the case of workforce data, each segment represents a group of people with similar characteristics, either that pertain to them as an individual (e.g., gender, race, educational background) or to their connection to the organization (e.g., their job title, supervisor, or work schedule).

There are a variety of ways to “slice and dice” your data into meaningful groups. Some possibilities are listed below. The squares represent the unit of categorization (e.g., agency structure), and dashed green squares represent the data segments (e.g., …

Department of Psychology: Faculty Publications

Objective—Precise phenotypic characterization of prenatal tobacco exposure (PTE) −related disruptive behavior (DB) that integrates nuanced measures of both exposures and outcomes is optimal for elucidating underlying mechanisms. Using this approach, our goals were to identify dimensions of DB most sensitive to PTE prior to school entry and assess contextual variation in these dimensions.

Methods—A community obstetric sample of N=369 women (79.2% lifetime smokers; 70.2% pregnancy smokers) from two Midwestern cities were assessed for PTE using cotinine-calibrated interview-based reports at 16, 28, and 40 weeks of gestation. A subset of n=244 who completed observational assessments with their …

Scaup Depredation On Arkansas Baitfish And Sportfish Aquaculture, Stephen A. Clements, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie Hanson-Dorr, Anita M. Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

Lesser scaup (Aythya affinis) and greater scaup (A. marila), hereafter scaup, consume a variety of aquatic invertebrates, plants, and occasionally small fish. Scaup have foraged on commercial aquaculture farms in the southern United States for decades. However, the types, abundance, and rate of fish exploitation by scaup on baitfish and sportfish farms are not well documented. Thus, information is needed to understand how fish and other foods influence scaup use of aquatic resources, and any potential economic effects of depredation of fish. From November–March in winters 2016–2017 and 2017–2018, we conducted 1,458 pond surveys to …

Review Of Benefits Of Nature Experience For Young Children, Donger Liu, Guy Trainin

Research and Evaluation in Education, Technology, Art, and Design

Progressing urbanization is having an impact on people’s lifestyles. Increasing indoor time results in the deprivation of human’s proximity to nature. Richard Louv (2008) coined the term “nature deficit disorder”, conceptualized the increasing phenomenon of children suffering from anxiety, ADHD, and obesity due to spending less time in nature and more time indoor. There is a growing body of literature focusing on the benefits of nature experience, nature exposure on young children’s physiological and psychological well-beings, such as physical health, attention, executive function, and behavioral regulation etc. This review focuses on the research articles that investigated the influence of nature …

United States Department of Agriculture Wildlife Services: Staff Publications

Little is known about disease transmission relevant contact rates at the wildlife-livestock interface and the factors shaping them. Indirect contact via shared resources is thought to be important but remains unquantified in most systems, making it challenging to evaluate the impact of livestock management practices on contact networks. Free-ranging wild pigs (Sus scrofa) in North America are an invasive, socially-structured species with an expanding distribution that pose a threat to livestock health given their potential to transmit numerous livestock diseases, such as pseudorabies, brucellosis, trichinellosis, and echinococcosis, among many others. Our objective in this study was to quantify …

Plague Exposure In Mammalian Wildlife Across The Western United States, Sarah N. Bevins, Jeffrey C. Chandler, Nicole Barrett, Brandon S. Schmit, Gerald W. Wiscomb, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Plague is caused by a bacterial pathogen (Yersinia pestis) that can infect a wide range of mammal species, but its presence in wildlife is often underappreciated. Using a large-scale data set (n = 44,857) that details the extent of Y. pestis exposure in wildlife, we document exposure in 18 wildlife species, including coyotes (Canis latrans), bobcats (Lynx rufus), and black bears (Ursus americanus). Evidence of plague activity is widespread, with seropositive animals detected in every western state in the contiguous United States. Pathogen monitoring systems in wildlife that are both large scale …

Data-Driven Management—A Dynamic Occupancy Approach To Enhanced Rabies Surveillance Prioritization, Amy J. Davis, Jordana D. Kirby, Richard B. Chipman, Kathleen M. Nelson, Amy T. Gilbert

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies lyssavirus (RABV) is enzootic in raccoons across the eastern United States. Intensive management of RABV by oral rabies vaccination (ORV) has prevented its spread westward and shown evidence of local elimination in raccoon populations of the northeastern US. The USDA, Wildlife Services, National Rabies Management Program (NRMP) collaborates with other agencies to implement broad-scale ORV and conducts extensive monitoring to measure the effectiveness of the management. Enhanced Rabies Surveillance (ERS) was initiated during 2005 and updated in 2016 to direct surveillance efforts toward higher-value specimens by assigning points to different methods of encountering specimens for collection (strange-acting, roadkill, surveillance-trapped, …

Linking Human Resources And Child Welfare Data (Video), Quality Improvement Center For Workforce Development

Workforce Analytics Resources

When examining workforce data, it can be valuable to capitalize on data from a variety of systems, such as various human resources (HR) databases, learning management systems, and child welfare information systems. Each can be useful on their own, but additional information can be learned when different types of data are connected. For example, applicant information may be stored in a database that is separate from other HR data on those hired, and there is value in looking at the connections between applicant data and later aspects of employment.

Data linkage involves pairing observations from two or more data files …

Down The Iron Path: Mitochondrial Iron Homeostasis And Beyond, Jonathan Dietz, Jennifer L. Fox, Oleh Khalimonchuk

Department of Biochemistry: Faculty Publications

Cellular iron homeostasis and mitochondrial iron homeostasis are interdependent. Mitochondria must import iron to form iron–sulfur clusters and heme, and to incorporate these cofactors along with iron ions into mitochondrial proteins that support essential functions, including cellular respiration. In turn, mitochondria supply the cell with heme and enable the biogenesis of cytosolic and nuclear proteins containing iron–sulfur clusters. Impairment in cellular or mitochondrial iron homeostasis is deleterious and can result in numerous human diseases. Due to its reactivity, iron is stored and trafficked through the body, intracellularly, and within mitochondria via carefully orchestrated processes. Here, we focus on describing the …
