Maximizing Legged Accelerations: A Matter Of Force, Time, And Gravity, Lance Brooks

Applied Physiology and Wellness Theses and Dissertations

Sprint running accelerations require runners to apply surface forces that: support body weight by pushing downward, accelerate the body horizontally by pushing backward, and align the direction of the push with the body’s mass center to maintain balance and posture, which imposes an upper limit on the average forward acceleration force equal to the average gravitational force (1.0 G) acting on the runner. This expectation arises from the mechanical constraints imposed by the need to generate sufficient vertical force to support body weight against gravity while simultaneously producing horizontal force to accelerate forward and aligning the push through the center …

Immunological Feedback Loops Generate Parasite Persistence Thresholds That Explain Variation In Infection Duration, Clayton E. Cressler, Daniel C.G. Metz, David A. Chang Van Oordt, Andrea L. Graham

School of Biological Sciences: Faculty Publications

Infection duration affects individual host fitness and between-host transmission. Whether an infection is cleared or becomes chronic depends on the complex interaction between host immune responses and parasite growth. Empirical and theoretical studies have suggested that there are critical thresholds of parasite dose that can determine clearance versus chronicity, driven by the ability of the parasite to manipulate host immunity. However, the mammalian immune response is characterized by strong positive and negative feedback loops that could generate duration thresholds even in the absence of direct immunomodulation. Here, we derive and analyse a simple model for the interaction between T-cell subpopulations …

Nfl Franchise Departures And Nearby Home Prices, Brad R. Humphreys, Geoffrey Propheter

Economics Faculty Working Papers Series

Research shows that US professional sports facilities positively impact nearby house prices. New facilities typically have existing teams, complicating a separate assessment of the impact of teams and facilities. Existing research analyzed departures of pro basketball teams, but arenas host many non-sporting events. These results may not generalize. We exploit the relocation of two professional football teams to investigate the impact of team departures on home sales. Difference-in-differences and repeat sales model results indicate proximity to one team represented an amenity while proximity to the other did not. Differences in urban form likely explains this heterogeneity.

Developing Alternative Grading Strategies, Brian M. Sackett

School of Medicine Faculty Publications

The popularity of e-cigarettes (vaping) has soared, creating a public health crisis among teens and young adults. Chronic vaping can induce gut inflammation and reduce intestinal barrier function through the production of the proinflammatory molecule hydrogen sulfide (H2S). This is particularly concerning for people with HIV (PWH) as they already face impaired immune function and are at a higher risk for metabolic dysregulation, diabetes, and chronic liver disease. Furthermore, PWH experience unhealthy behaviors, making it crucial to understand the systemic metabolic dysregulation and pathophysiological mechanisms associated with vaping in this population. Here, we employed liquid chromatography–mass spectrometry (LC-MS)-based metabolomics to …

Developing Conflict Resolution Skills In Residential Students At Higher Education Institutions, Lindsey A. Bos

Masters Projects

For many college students, living on campus is the first experience that students have living outside their familial home. Students may take this leap with people they have developed prior relationships with, or with people they have just met. Regardless, this collision of differing norms has the potential to lead to interpersonal conflict. To support residential students at higher education institutions, this project utilizes the theoretical lenses of Maslow’s (1943) hierarchy of needs, Sanford’s (1966) challenge and support theory, and Chickering’s (1969) seven vectors of development to create a workshop curriculum aimed at developing students’ conflict resolution skills. Highlighting the …

Biological Sciences Faculty Publications and Presentations

• ‘Early detection and rapid response’ (EDRR) is the most successful framework for preventative invasive species management, but prioritizing localized EDRR actions with limited resources is challenging. An approach that ranks individual locations, such as waterbodies, for EDRR by combining an invasive species' establishment risk with the practicality of managing it could help set reasonable priorities.
• Here, we worked with regional practitioners in Arkansas, USA, and the broader Southeastern USA to co-produce a workflow for preventative aquatic invasive species management that (1) estimates establishment risk under current and future climates with a species distribution model, (2) scores waterbodies according to difficulty …

To manage and organize historical data and knowledge, our group (SDLE) at CWRU follows FAIR (Findable, Accessible, Interoperable, Reusable) principles, which outline the best practices for data stewardship and data provenance, and ontology, a formal representation of terms and concepts and their relationships, as a tool to improve …

Tackling No-Shows In Fine Dining: Insights Into Cancellation Policies And Consumer Awareness Campaigns, Esther Kim, Jason Tang

Department of Hospitality and Tourism Faculty Scholarship and Creative Works

This research aims to identify how fine dining restaurants can effectively implement reservation cancellation policies to address the issue of no-shows by applying equity theory, the dual entitlement principle, and social cognitive theory. Two experiments identified cancellation policy elements that influence restaurant evaluations and reservation behaviors. Findings revealed that cancellation policies negatively influence restaurant evaluations, and that policy strictness and awareness can attenuate this relationship via perceived fairness while enhancing the likelihood to book reservations and honor reservations. This research suggests that restaurants can benefit from implementing lenient cancellation policies and introducing awareness of the adverse impact of no-shows to …

Stanniocalcin 2 Governs Cancer Cell Adaptation To Nutrient Insufficiency Through Alleviation Of Oxidative Stress, Shuo Qie, Haijuan Xiong, Yaqi Liu, Chenhui Yan, Yalei Wang, Lifeng Tian, Chenguang Wang, Nianli Sang

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Solid tumours often endure nutrient insufficiency during progression. How tumour cells adapt to temporal and spatial nutrient insufficiency remains unclear. We previously identified STC2 as one of the most upregulated genes in cells exposed to nutrient insufficiency by transcriptome screening, indicating the potential of STC2 in cellular adaptation to nutrient insufficiency. However, the molecular mechanisms underlying STC2 induction by nutrient insufficiency and subsequent adaptation remain elusive. Here, we report that STC2 protein is dramatically increased and secreted into the culture media by Gln-/Glc- deprivation. STC2 promoter contains cis-elements that are activated by ATF4 and p65/RelA, two transcription factors activated by …
