An Overview Of The Forensic Analysis And Use Of Non-Human Dna, Kaelyn Long Apr 2022

An Overview Of The Forensic Analysis And Use Of Non-Human Dna, Kaelyn Long

Senior Honors Theses

DNA is present in every living organism on Earth. DNA is also present in a few non-living biological agents such as DNA-containing viruses, and is additionally unique to particular groups of organisms and often even to individuals. This characteristic allows DNA to be quite useful in forensic investigations. This study takes an in-depth look at the forensic use of non-human DNA. DNA analysis is a key component of many forensic investigations, but the majority of these analyses are focused on human DNA. This review examines the ways in which non-human DNA can be useful to forensic investigations. The various unique …


The Rise Of Concentrated Animal Feeding Operations, Their Effects, And How We Can Stop Their Growth, Andrea Prisco Apr 2022

The Rise Of Concentrated Animal Feeding Operations, Their Effects, And How We Can Stop Their Growth, Andrea Prisco

Dickinson Law Review (2017-Present)

Dramatic changes in the agricultural industry over the last century have led to the rise of concentrated animal feeding operations– industrial facilities that raise a large number of animals in confined spaces. Animals raised in these facilities suffer from poor quality of life and abuse. For humans, these facilities have had adverse effects on the environment and public health, but they are also associated with high productivity and low food costs. This Comment analyzes the effects of concentrated animal feeding operations on animal well-being, the environment, and public health. This Comment also analyzes current federal legislation that helps combat the …

A Push For Inclusive Data Collection In Stem Organizations, Nicholas P. Burnett, Alyssa M. Hernandez, Emily E. King, Richelle L. Tanner, Kathryn Wilsterman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Professional organizations in STEM (science, technology, engineering, and mathematics) can use demographic data to quantify recruitment and retention (R&R) of underrepresented groups within their memberships. However, variation in the types of demographic data collected can influence the targeting and perceived impacts of R&R efforts - e.g., giving false signals of R&R for some groups. We obtained demographic surveys from 73 U.S.-affiliated STEM organizations, collectively representing 712,000 members and conference-attendees. We found large differences in the demographic categories surveyed (e.g., disability status, sexual orientation) and the available response options. These discrepancies indicate a lack of consensus regarding the demographic groups that …

Mytrials: Clinical Trial Application Concept, Katie Hollister

Graphic Communication

A clinical trial’s success is dependent upon whether a patient attends their highly-structured clinical trial visit schedule, which may include both in-person clinic visits and virtual check-in visits. MyTrials is a clinical trial journey app prototype that enables patients to schedule, reschedule, and attend join their in-person or virtual clinic visits. This product seeks to reduce the burden that scheduling places on the patient, and provides trial-provided resources and a daily and weekly timeline to help patients navigate their clinical trial journey.

The coxsackievirus and adenovirus receptor (CAR) is an essential cellular protein that is involved in cell adhesion, cell signaling, and viral infection. The 8-exon encoded isoform (CAREx8) resides at the apical surface of polarized epithelia, where it is accessible as a receptor for adenovirus entering the airway lumen. Given its pivotal role in viral infection, it is a target for antiviral strategies. To understand the regulation of CAREx8 and determine the feasibility of receptor down regulation, the half-life of total and apical localized CAREx8 was determined and correlated with adenovirus transduction. Total and apical CAREx8 has a relatively short half-life …

Led by His Holiness the Dalai Lama, the initiative taken by the Tibetan Buddhist monastic community to connect with western science and scientists presents a unique opportunity to understand the motivations and engagement behaviors that contribute to monastic science learning. In this study, we draw on quantitative data from two distinct surveys that track motivations and engagement behaviors related to science education among monastic students. The first survey was administered at one monastic university in 2018, and the second follow-up survey was completed by students at two monastic universities in 2019. These surveys assessed the reception of science education related …


Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber Jan 2022

Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber

Electronic Theses and Dissertations

Fires impact ecosystems globally and due to climate change, there are shifts in fire regimes that impact ecological communities which provide essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level responses for most functional groups with herbivores as the only exception showing some positive effects of fire. We also studied mixed-severity fires that burned >20 years ago and compared floral visitor communities across fire severities. We implemented a pollinator exclusion experiment …

Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young

Theses and Dissertations

Post-traumatic stress disorder is a stress and trauma based psychological disorder that is defined by the DSM-IV as an anxiety disorder that affects approximately 7.8% of people in the United States. PTSD is when those who suffer a traumatic event have intense and distressing feelings, emotions, and memories for a prolonged period of time after the event. A prominent feature of PTSD is the impaired ability to properly extinguish a fear response after a dangerous trigger or stressor is no longer present, also known as safety learning. Stressors are threats perceived within the environment that activate a response within the …


Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper Jan 2022

Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper

Human–Wildlife Interactions

Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …

Coastal marine habitats continue to be degraded, thereby compelling largescale restoration in many parts of the world. Whether restored habitats function similarly to natural habitats and fully recover lost ecosystem services is unclear. In estuaries, oyster reefs have been degraded by multiple anthropogenic activities including destructive fishing practices and reduced water quality, motivating restoration to maintain oyster fisheries and other ecosystem services, often at relatively high cost. We compared fish and invertebrate communities on recently restored (0–1 year post-restoration), older restored (3–4 years post-restoration), and natural oyster reefs to determine if and when restored reefs support functionally similar faunal communities. …

Population Dynamics, Relative Abundance, And Habitat Suitability Of Adult Red Drum (Sciaenops Ocellatus) In Nearshore Waters Of The North-Central Gulf Of Mexico, Crystal Hightower, J. Marcus Drymon, Amanda E. Jefferson, Matthew B. Jargowsky, Emily A. Seubert, Simon Dedman, John Mareska, Sean P. Powers

University Faculty and Staff Publications

In the Gulf of Mexico, the red drum (Sciaenops ocellatus) is an immensely popular sportfish, yet the Gulf of Mexico stock is currently managed as data-limited in federal waters. The results of the federal stock assessment conducted in 2016 for Gulf of Mexico red drum were not recommended for providing management advice. Consequently, we sought to address data gaps highlighted in the assessment by producing up-to- date overall and sex-specific growth models, standardized indices of relative abundance, and predictions of habitat suitability and by updating estimates of natural mortality. Using a time series for the period of 2006–2018, we assigned …


Public Perceptions Of Human Physical Interactions, Exhibition, And Conservation Of Tigers And Cheetahs, Abbie Knudsen Jan 2022

Public Perceptions Of Human Physical Interactions, Exhibition, And Conservation Of Tigers And Cheetahs, Abbie Knudsen

Graduate Theses/Dissertations

Tigers and cheetahs are common in the pet trade, public exhibits, and hands-on encounters with the public. Poor regulation of these experiences has resulted in numerous incidents worldwide in which a person was seriously injured or killed by captive big cats. Additionally, concerns for animal welfare have been raised by industry professionals. Prior research on primates has demonstrated exposing people to photographs of cats in different backgrounds can influence their attitudes about animals in captivity, but no study has addressed whether visual images affect human attitudes toward big cats. I used a survey that asked a series of questions about …
