Prevalence And Prevention Of The Female Athlete Triad, Elizabeth Dachenhaus

Honors Projects

A study was composed to analyze the three components of the female athlete triad: disordered eating, amenorrhea, and osteoporosis. The cyclic behavior of these three components and determination of which of the pillars of the triad is the most dangerous was also focused on. In order to test the prevalence of disordered eating among women’s collegiate teams, a brief survey was distributed and analyzed among athletes at Bowling Green State University. In addition to confirming that women in aesthetic sports experience a greater amount of disordered eating on the team, the survey also identified women that participated in sports perceived …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

The Correlation Between Snakebites And Meteorological Variations, Chang Na

Public Health Theses

Background: In the United States, approximately 45,000 snakebites occur annually and affect many people including veterinarians and farmers.1 Snakebites can cause significant pain and morbidity such as severe bleeding and skin necrosis. Better predictive information on snakebite risk could help prevent snakebites by identifying high risk time periods, weather patterns, and locations.

Methods: This was a retrospective analysis of the New Mexico State Poison Control Center data between January 1998 and December 2012. Monthly average meteorological data were obtained from the Parameter-elevation Regressions on Independent Slopes Model climate group. Locations of the bites were categorized as urban or rural based …

Economics Of Distillers Grains Supplementation In A Forage System With Spayed Heifers, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider, Galen Erickson, J. D. Volesky

Nebraska Beef Cattle Reports

In a two-year study, spayed heifer calves were backgrounded on cornstalks with 2 lb or 5 lb wet distillers grains with solubles supplemented daily. During the summer, heifers grazed native range and received no summer supplementation or were supplemented with modified distillers grains with solubles at 0.6% BW daily. Heifers were finished on a common regimen, and an economic scenario was applied to each phase of production and overall. Supplementing more in winter increased profit, but summer supplementation did not impact overall profitability. Numerically, heifers not supplemented during the summer were more profitable than supplemented heifers.

Effect Of Winter Supplementation Level On Yearling System Profit Across Economic Scenarios, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider

Nebraska Beef Cattle Reports

Calves backgrounded in a forage–based, yearling system at a greater ADG maintained a performance advantage through finishing. High-level supplemented cattle gained an additional 0.18 lb daily during finishing and produced an additional 81 lb of saleable live weight compared to cattle backgrounded at a low-supplementation level. Across four economic scenarios with varying corn and distillers prices, high-level supplemented cattle returned $55.54 more than cattle fed a low level of supplementation during the winter backgrounding phase. Corn price would have to exceed $11.70/bu for high supplementation level to no longer be profitable.

Effects Of Calf Age At Weaning On Cow And Calf Performance And Efficiency In A Drylot/Confinement Production System, Jason M. Warner, Karla H. Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

An ongoing study evaluated the effectsof calf age at weaning on cow and calf performance and reproduction in a confinement production system. Early-weaning improved cow BW at normal weaning. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake was not different between early-weaned cows and calves compared with normal-weaned pairs. Feed requirements and energy utilization were equal between early- and normal-weaned pairs when fed a distillers grains and crop residue based diet.

Effects Of Dietary Change On Viral-Bacterial Interactions In The Rumen Of Cattle, Christopher L. Anderson, Melissa L. Jolly, Adam L. Shreck Shreck, Galen E. Erickson, Terry J. Klopfenstein, Samodha C. Fernando

Nebraska Beef Cattle Reports

This ongoing study investigates the impact of diet and bacteriophage activity on the structuring of rumen microbial community composition and diversity. Fistulated cattle were acclimated to a given diet for 21 days before samples were collected and subsequently enriched for viral particles with tangential flow filtration. Taxonomic identification, abundance, and functional attributes were assigned to both bacterial and viral communities. Principle coordinate analysis of the bacterial communities revealed significant clustering based on diet. While diet drives the structuring of rumen bacterial communities, bacteriophages may maintain high, constant bacterial diversity.

Statistics Used In The Nebraska Beef Report And Their Purpose, University Of Nebraska-Lincoln

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at University of Nebraska–Lincoln is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore, he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the majorstatistics used in the beef report. For a more detailed description …

Determination Of The Expression Patterns Of The Nine Csp Genes In Escherichia Coli K-12 Mg1655 And The Growth Defects Associated With Deletion Of These Genes, Tiffany R Czapski

Electronic Theses and Dissertations

Cold-shock proteins (CSPs) are a family of small nucleic acid-binding proteins. In Escherichia coli K-12, there are 9 homologous csp genes named A-I. Aside from microarray studies, transcript levels from all nine csp genes have never been assayed using the same technique. The objectives of this study were to determine when these genes are expressed, if homologous pairs are expressed the same, how many are cold-shock inducible, and if there is a ranking of importance for these genes. To answer these questions, I determined csp mRNA expression patterns for all nine csp genes during normal growth at 37°C, and after …

Publications and Research

Thailand is among the few less-developed countries with successful HIV prevention among segments of the population (National AIDS Prevention and Alleviation Committee, 2010). However, the success of HIV prevention among Thai adolescents and young adults has been questionable. The highest percentage of Thai persons with AIDS remain in the age group of 25–34 years, indicating that the time of greatest HIV acquisition has occurred in adolescence and young adulthood (Thai Working Group on HIV/AIDS, 2010). Most Thai youth living with HIV (TYLH) acquire HIV through sexual contact (National AIDS Prevention and Alleviation Committee, 2010). In a study of TYLH, only …

A Positive Future For Section 7?: Children And Charter Change, Alison M. Latimer

The Supreme Court Law Review: Osgoode’s Annual Constitutional Cases Conference

It has been more than a decade since Justice Arbour’s dissenting judgment in Gosselin, the first and only Supreme Court of Canada judgment recognizing positive rights under section 7. The jurisprudence that has developed in the intervening years presents some challenges to pursuing such a claim today. Yet the author offers the view that because of the special vulnerability of children, their capacity for development and the state’s treatment of children in other contexts, recognition of positive rights for children is consistent with Canada’s legal/political traditions, current laws and jurisprudence. Childhood, the refore, may well be the “special circumstance” necessary …

Identifying Influential Agents In Social Systems, Mahsa Maghami

Electronic Theses and Dissertations

This dissertation addresses the problem of influence maximization in social networks. In- fluence maximization is applicable to many types of real-world problems, including modeling contagion, technology adoption, and viral marketing. Here we examine an advertisement domain in which the overarching goal is to find the influential nodes in a social network, based on the network structure and the interactions, as targets of advertisement. The assumption is that advertisement budget limits prevent us from sending the advertisement to everybody in the network. Therefore, a wise selection of the people can be beneficial in increasing the product adoption. To model these social …

Integrated Remote Sensing And Forecasting Of Regional Terrestrial Precipitation With Global Nonlinear And Nonstationary Teleconnection Signals Using Wavelet Analysis, Lee Mullon

Electronic Theses and Dissertations

Global sea surface temperature (SST) anomalies have a demonstrable effect on terrestrial climate dynamics throughout the continental U.S. SST variations have been correlated with greenness (vegetation densities) and precipitation via ocean-atmospheric interactions known as climate teleconnections. Prior research has demonstrated that teleconnections can be used for climate prediction across a wide region at sub-continental scales. Yet these studies tend to have large uncertainties in estimates by utilizing simple linear analyses to examine chaotic teleconnection relationships. Still, non-stationary signals exist, making teleconnection identification difficult at the local scale. Part 1 of this research establishes short-term (10-year), linear and non-stationary teleconnection signals …

The Possession Heuristic, James E. Krier, Christopher Serkin

Law & Economics Working Papers

This chapter for the forthcoming book, The Law and Economics of Possession (Yun-chien Chang, ed), explores the law of possession as an application of a heuristic (a simple decision making strategy devised to solve complex problems, part of System 1 thinking in Daniel Kahneman’s famous formulation). Since the law of property is essentially the law of belongings, its first task is to determine to whom things belong. There are all sorts of complicated inquiries that could be undertaken to figure out and justify an incredible range of answers to this question. Alternatively, there is a simple inquiry that provides a …

Nel Positively Regulates The Genesis Of Retinal Ganglion Cells By Promoting Their Differentiation And Survival During Development, Chizu Nakamoto, Soh-Leh Kuan, Amy Findlay, Elaine Durward, Zhufeng Ouyang, Masaru Nakamoto, Ewa Zakrewska, Takuma Endo

Biology Faculty Publications

For correct functioning of the nervous system, the appropriate number and complement of neuronal cell types must be produced during development. However, the molecular mechanisms that regulate the production of individual classes of neurons are poorly understood. In this study, we investigate the function of the thrombospondin-1–like glycoprotein, Nel (neural epidermal growth factor [EGF]-like), in the generation of retinal ganglion cells (RGCs) in chicks. During eye development, Nel is strongly expressed in the presumptive retinal pigment epithelium and RGCs. Nel overexpression in the developing retina by in ovo electroporation increases the number of RGCs, whereas the number of displaced amacrine …
