In-Class Versus At-Home Quizzes: Which Is Better? A Flipped Learning Study In A Two-Site Synchronously-Broadcast Organic Chemistry Course, Michael A. Christensen, Alyssia M. Lambert, Louis S. Nadelson, Kami M. Dupree, Trish A. Kingsford

Chemistry and Biochemistry Faculty Publications

We recently shared our design of a two-semester flipped organic chemistry course, in which we gave students in-class quizzes to incentivize attendance and watching the lecture videos in advance. With a second iteration, we planned to make the video-watching experience more engaging. We accordingly hypothesized that if students completed short at-home quizzes while watching the videos, then attentiveness, engagement, and learning would increase. We tested this with a later section of the course, dividing the material into 13 units. For units 1-6, we gave in-class quizzes; for 7-13, quizzes were at home. Although units 1-6 and 7-13 covered different material, …

Groundwater-Flow Model Of The Northern High Plains Aquifer In Colorado, Kansas, Nebraska, South Dakota, And Wyoming, Steven M. Peterson, Amanda T. Flynn, Jonathan (Jp) Traylor

United States Geological Survey: Water Reports and Publications

The High Plains aquifer is a nationally important water resource underlying about 175,000 square miles in parts of eight states: Colorado, Kansas, Oklahoma, Nebraska, New Mexico, South Dakota, Texas, and Wyoming. Droughts across much of the Northern High Plains from 2001 to 2007 have combined with recent (2004) legislative mandates to elevate concerns regarding future availability of groundwater and the need for additional information to support science-based water-resource management. To address these needs, the United States Geological Survey (USGS) began the High Plains Groundwater Availability Study to provide a tool for water-resource managers and other stakeholders to assess the status …

Distributed All-Ip Mobility Management Architecture Supported By The Ndn Overlay, Zhiwei Yan, Guanggang Geng, Sherali Zeadally, Yong-Jin Park

Information Science Faculty Publications

Two of the most promising candidate solutions for realizing the next-generation all-IP mobile networks are Mobile IPv6 (MIPv6), which is the host-based and global mobility supporting protocol, and Proxy MIPv6 (PMIPv6), which is the network-based and localized mobility supporting protocol. However, the unprecedented growth of mobile Internet traffic has resulted in the development of distributed mobility management (DMM) architecture by the Internet engineering task force DMM working group. The extension of the basic MIPv6 and PMIPv6 to support their distributed and scalable deployment in the future is one of the major goals of the DMM working group. We propose an …

Improved Genome-Scale Multitarget Virtual Screening Via A Novel Collaborative Filtering Approach To Cold-Start Problem, Hansaim Lim, Paul Gray, Lei Xie, Aleksandar Poleksic

Publications and Research

Conventional one-drug-one-gene approach has been of limited success in modern drug discovery. Polypharmacology, which focuses on searching for multi-targeted drugs to perturb disease-causing networks instead of designing selective ligands to target individual proteins, has emerged as a new drug discovery paradigm. Although many methods for single-target virtual screening have been developed to improve the efficiency of drug discovery, few of these algorithms are designed for polypharmacology. Here, we present a novel theoretical framework and a corresponding algorithm for genome-scale multitarget virtual screening based on the one-class collaborative filtering technique. Our method overcomes the sparseness of the protein-chemical interaction data by …

Formulation Of Colloidal Suspensions Of 3-Mercaptopropionic Acid Capped Pbs Quantum Dots As Solution Processable Qd "Inks" For Optoelectronic Applications, Chase Collier Reinhart

Dissertations and Theses

The use of colloidal quantum dots (QDs) for photovoltaic energy conversion is a nascent field that has been dominated for well over a decade by the use of 3-mercaptopropionic acid (3-MPA) capped PbS QDs. These QDs are routinely deposited via an in situ solid state ligand exchange process that displaces the native oleate ligand on the PbS QD surface. This ligand exchange procedure is wasteful of material and has been demonstrated to leave numerous impurities that limit electronic performance of the as-deposited QD devices. Until the last few years there was very little understanding in chemical literature as to many …

Precision Study Of Stochastic Predictors For Dxa Scans, Raul Ramos

Health and Kinesiology Theses

In this study, the in vivo reproducibility of stochastic predictors and BMD values from Dual- Energy X-ray Absorptiometry (DXA) were assessed at two different anatomic sites: hip and spine. Measurement of bone mineral density (BMD) derived from DXA has been widely used as a diagnostic tool for osteoporosis. BMD has been used as a representative value for bone strength and fracture risk, but only represents a part of both. In order to better understand fracture risk, the use of grayscale images from DXA scans has been implemented in enhancing the prediction of bone strength and fracture risk. The use of …

The participants in this study included nine parents and ten students at an urban Title I theme school. The data collection process included two focus group interviews, nineteen semi-structured individual interviews, journal entries from each participant and 15 documents disseminated to parents from the school and from the district. Three themes emerged from the data: (a) the parents’ understanding/confusion about the “new math” and the effects on parent engagement with mathematics, (b) the …

Career Morph: Quantitizing Adversity In Academic Medicine, Carol Isaac, Rebecca Mcsorley, Alexandra Schultz

The Qualitative Report

Many qualitative researchers reject textual conversion based on philosophical grounds although others believe it facilitates pattern recognition and meaning extraction. This article examined interview data from 52 physicians from a large academic medical center regarding work–life balance. Analysis ranked men and women in four career tracks: Clinician-Educator, Clinician-Researcher, Clinician-Practitioner, and residents. The purpose of this paper is to illustrate how a qualitatively driven (QUAL→quan) mixed method design illustrated differences between stratified groups. Although many initial codes were similar for men and women, their language was gendered and generational in context of work-life balance. Results indicated that women (and low-status men) …

Objectives: This work was conducted to create a predictive mathematical model for Salmonella spread, distribution and outbreak in local wastewater resources with understanding the mechanisms and impacts of seasonal environmental drivers.

Methods: Empirical models were developed to solve several biologically distinct mechanisms of Salmonella sp by which seasonality can impact their interactions, including seasonal changes in replication, distribution and mortality rates.

Results: Mathematical models and field observations show that the strength and mechanisms of seasonality can alter the spread and …

The Evolution Of Zero-Tolerance Policies, Stephanie D. Stahl

CrissCross

Most Americans today have a largely negative image of zero-tolerance policies (ZTP) enacted to stop and prevent violence in the United States school system. According to the U.S. Department of Education Office of Educational Research and Improvement, zero-tolerance procedures are policies that mandate predetermined consequences or punishments for specific offenses (Walker). These policies specifically targeted actions considered violent and threatening, such as possession of a firearm or weapon. The concept of zero-tolerance policies was introduced into the education system during the 1980s as part of the failed War on Drugs as an attack on drug usage and violence in schools. …

The Labyrinth Of The Mind: The Psychology Of War Stories In Tim O’Brien’S Going After Cacciato, Rebekah Smith

CrissCross

This paper explores and analyzes the psychological reasons for storytelling by soldiers and veterans both during and after their deployments in war. It brings in multiple works by author-veterans as well as critical writing about these books with a specific focus on Going After Cacciato by Tim O'Brien. Paul Berlin, the novel's protagonist, imagines a fictional quest leaving Vietnam and going all the way to Paris following the desertion of a fellow soldier gone AWOL. He creates this journey to create order, find meaning, generate understanding, and focus on the good rather than the bad. This paper also explores the …

American Spring, Sam Mullooly, Tom Mullooly

CrissCross

Composer's Notes

I composed American Spring during the 2015-2016 school year, my final year as an undergraduate at Illinois Wesleyan University, in connection with the 150th anniversary of the end of the Civil War. This opera takes place mostly in April 1865, the year Richmond burned and Lincoln died, and deals with America’s feelings of pride and shame in war. The opera’s main character is Varina Davis, the wife of confederate President Jefferson Davis. Varina offers the 1860’s Southern perspective on slavery and the war, one glossed over in most readings of our history because it is so obviously repugnant …

Birthing Center Versus Hospitalized Birth, Nicolette Larsen

CrissCross

There are many risks and benefits of giving birth at a birthing center versus a hospital. Determining the location of birth is an important decision, as women in the world today have many options of where to have their child. Hospitals and birthing centers are two places where medical professionals provide prenatal, labor and delivery, and postpartum care for the mother and fetus during this memorable time. While hospital nurses and physicians provide advanced medical care, birthing centers focus on holistic care of the family unit emphasizing mental, spiritual, and physical health. Doctors often perform cesarean sections (C-sections) for non-medical …

A Park Story, David Flowers, Evan Dolan

CrissCross

Composer's Note

A Park Story was written to be an honest and objective portrayal of the struggles that both characters experience throughout their collective story. Christopher and his mother both end up fighting two dominating perspectives of their identity: their family roles, and how they identify themselves. Their self-identities collide with each other in an irreconcilable manner; while both of them strongly desire the family bond they have, the mother’s convictions become the line that neither of them have any desire to cross.

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-Wildlife Conflict In Selela Village, Nicole Chlebek, Laura Stalter

CrissCross

The beastly journey of long-distance migration for the African Elephant (Lexodonta Africana) is important for upholding their connections between diminishing protected areas, especially in northeastern Tanzania. However, human development is encroaching into these corridors, creating a human-elephant conflict, which can ruin livelihoods of villagers, depending on the extent of conflict. This study focused on exploring the hypothesized human-elephant conflict on the Selela corridor, specifically in Selela village, as well as GPS (Global Positioning System) mapping evidence of elephant travel along the projected Selela elephant corridor connecting Ngorongoro Conservation Area (NCA), to Selela Forest Reserve (SFR), and finally to …

Cultural Intelligence Sounding The Death Knell For Stereotypes In Business Communication, Eugene A. Ohu

Global Advances in Business Communication

Globalization is creating culturally diverse teams. Managers are increasingly challenged to lead multicultural teams towards common organizational goals. It has therefore become imperative that team members be helped to quickly attain a shared understanding of messages. Much research has focused on generating awareness of different cultures and how this knowledge can be used to improve business communication.

Even with this awareness that different cultures exist, stereotypes (of race, gender, national culture) still influence how team members interpret the actions of their colleagues. Studies in social psychology have focused on how stereotypes influence perceptions about individuals or groups of people. Message …

Anthropogenic Disturbance Modulates Mammal Community Diversity, Assembly, & Abundance: Emerging Infectious Disease Risk In The Greater Yellowstone Ecosystem, Leticia Andrea Gutiérrez Jiménez

Dissertations

This dissertation examines the role of mammalian biodiversity in maintaining overall ecosystem health in the Greater Yellowstone Ecosystem (GYE). The study explores the pathways by which anthropogenic disturbance prevents or promotes the emergence of human infectious diseases. I studied two paramount research questions: Question 1: What are the direct effects of anthropogenic disturbance on rodent community assemblages and the consequent indirect effects on public health? I first surveyed the GYE rodent community and their pathogens by using land use as a measure of anthropogenic disturbance (e.g., human settlements, horseback ranches, pastures, undisturbed). I identified pathogens in rodent blood samples by …

An Algorithm For Calculating The Inverse Jacobian Of Multirobot Systems In A Cluster Space Formulation, Christopher Jude Waight

Mechanical Engineering Master's Theses

Multirobot systems have characteristics such as high formation re-configurability that allow them to perform dynamic tasks that require real time formation control. These tasks include gradient sensing, object manipulation, and advanced field exploration. In such instances, the Cluster Space Control approach is attractive as it is both intuitive and allows for full degree of freedom control. Cluster Space Control achieves this by redefining a collection of robots as a single geometric entity called a cluster. To implement, it requires knowing the inverse Jacobian of the robotic system for use in the main control loop. Historically, the inverse Jacobian has been …

Relationship Between Preponderance Of Adhd In The African American Community And How Teachers Are Trained To Type Students As Adhd, E Madison

Capstone Collection

The following capstone paper “Relationship between preponderance of ADHD in African American community and how teachers are trained to type students as ADHD” explores the epidemic of Attention Deficit Hyperactivity Disorder (ADHD) diagnosis in students and the prevalence of ADHD in the African American community. In recent years the number of African American children with ADHD have skyrocketed concerning parents about the over diagnoses and misdiagnoses of the disorder (Ahmann, 2016). A recent study by Getahun and colleagues found a "70 percent increase in the number of ADHD diagnoses among African American children, with a 90 percent increase among African …

Active Learning Tour Route: Engagement In An Unconventional Environment, Hattie Molina

Honors Projects

When guest attend Bowling Green State University for a campus visit, a majority of their experience is comprised of tour guides talking “at” them. The campus tour is made up of a lot of facts and stories provided by the tour guide, but few questions by guests or based on comments from guests. One way to solve this is to create an Active Learning Tour route where guest are the center of their own campus learning experience. According to the research, the components of Active Learning have many facets that branch into other aspects including technology and humor. The aim …

Synthesis Of Optimization And Simulation For Multi-Period Supply Chain Planning With Consideration Of Risks, Liang Xu

Dissertations

Solutions to deterministic optimizing models for supply chains can be very sensitive to the formulation of the objective function and the choice of planning horizon. We illustrate how multi-period optimizing models may be counterproductive if traditional accounting of revenue and costs is performed and planning occurs with too short a planning horizon. We propose a “value added” complement to traditional financial accounting that allows planning to occur with shorter horizons than previously thought necessary. This dissertation presents a simulation model with an embedded optimizer that can help organizations develop strategies that minimize expected costs or maximize expected contributions to profit …
