Thrust Production And Chordal Flexion Of The Flukes Of Bottlenose Dolphins Performing Tail Stands At Different Efforts, David Kramer, Maura J. Sheehan, Frank E. Fish Mar 2024

Thrust Production And Chordal Flexion Of The Flukes Of Bottlenose Dolphins Performing Tail Stands At Different Efforts, David Kramer, Maura J. Sheehan, Frank E. Fish

Biology Faculty Publications

Dolphins have become famous for their ability to perform a wide variety of athletic and acrobatic behaviors including high-speed swimming, maneuverability, porpoising and tail stands. Tail stands are a behavior where part of the body is held vertically above the water's surface, achieved through thrust produced by horizontal tail fluke oscillations. Strong, efficient propulsors are needed to generate the force required to support the dolphin's body weight, exhibiting chordwise and spanwise flexibility throughout the stroke cycle. To determine how thrust production, fluke flexibility and tail stroke kinematics vary with effort, six adult bottlenose dolphins (Tursiops truncatus) were tested at three …

Inverse Association Between Exercising Blood Pressure Response And Left Ventricular Chamber Size And Mass In Women Who Habitually Resistance Train, Evan L. Matthews, John J. Guers, Meghan G. Ramick, Peter A. Hosick Feb 2024

Inverse Association Between Exercising Blood Pressure Response And Left Ventricular Chamber Size And Mass In Women Who Habitually Resistance Train, Evan L. Matthews, John J. Guers, Meghan G. Ramick, Peter A. Hosick

Kinesiology Faculty Publications

Exercise is a major modifiable lifestyle factor that leads to temporarily increased systolic blood pressure (SBP), which is thought to influence left ventricular mass normalized to body surface area (LVM/BSA). This relationship has never been studied in women who habitually perform resistance exercise. Purpose: To determine if a direct correlation exists between the SBP response to resistance exercise (change from rest; eSBP) and LVM/BSA in young healthy women who habitually resistance train. Methods: Leg extension resistance exercise was performed while continuously monitoring blood pressure using finger plethysmography. LVM was estimated using echocardiography. Data are shown as mean +/- SD. Results: …


The Diversity Of Wolbachia Across The Turtle Ants (Formicidae: Cephalotes Spp.), Corey Reese, Leland C. Graber, Manuela O. Ramalho, Corrie S. Moreau Feb 2024

The Diversity Of Wolbachia Across The Turtle Ants (Formicidae: Cephalotes Spp.), Corey Reese, Leland C. Graber, Manuela O. Ramalho, Corrie S. Moreau

Biology Faculty Publications

Wolbachia is a widespread and well-known bacterium that can induce a wide range of changes within its host. Ants specifically harbor a great deal of Wolbachia diversity and are useful systems to study endosymbiosis. The turtle ants (Cephalotes) are a widespread group of tropical ants that rely on gut microbes to support their herbivorous diet for their survival, yet little is known of the extent of this diversity. Therefore, studying their endosymbionts and categorizing the diversity of bacteria within Cephalotes hosts could help to delimit species and identify new strains and can help lead to a further understanding of how …


Waiting On The World (Of Allied Healthcare) To Change: How Undergraduate Preparedness Curriculum Dis/Includes Ability, Brianna Donnelly Jan 2024

Waiting On The World (Of Allied Healthcare) To Change: How Undergraduate Preparedness Curriculum Dis/Includes Ability, Brianna Donnelly

West Chester University Doctoral Projects

Significant concerns for healthcare practitioners and allied health professionals continue to arise regarding treatment of persons with disabilities. Whether disability exists as apparent or non-apparent, temporary, or chronic, people with disabilities tend to be in poorer health and tend to use health care at a significantly higher rate than people who do not have disabilities. Importantly, the absence of professional training on disability competency issues for health care practitioners is one of the most significant barriers that prevent people with disabilities from receiving appropriate and effective health care. This qualitative narrative analysis explores the inclusion of disability concepts and people …


Assessing Changing Carbon Pool Dynamics And Species Composition In A Pennsylvania Broadleaf Forest Fragment, Kyleigh Levinsky, Jessica L. Schedlbauer Jan 2024

Assessing Changing Carbon Pool Dynamics And Species Composition In A Pennsylvania Broadleaf Forest Fragment, Kyleigh Levinsky, Jessica L. Schedlbauer

Sustainability Research & Creative Activities Grants Reports

Temperate broadleaf forests are pivotal to the global carbon cycle, Representing 37% of the global forest carbon pool (Pan et al 2011). • Maintaining compositional diversity in temperate broadleaf forests, such as the Gordon Natural Area (GNA) is critical to maintaining ecosystem services, such as carbon sequestration. • Pressures from native and non-native herbivores threaten the biodiversity of temperate broadleaf forests in the United States (Ghandi et al. 2010). The introduction of non-native insects such as the emerald ash borer (Argrilus planipennis), as well as the overpopulation of white-tailed deer (Odocoileus virginianus) has led to declines in some tree species. …


Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal Jan 2024

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …
