The parametric...

Designing for the One-Shot: Building Consensus on Design Processes for Academic Librarians

Kirsten Hostetler
Academic librarians have long been responsible for teaching information literacy competencies on college campuses, even as many are hesitant to accept the title of teacher. With inadequate instructional design preparation and one-shot sessions serving as a popular, if limited, instructional medium, librarians’ design processes are often developed on the job and infrequently explored in the literature. Previous research has examined specific design models and instructional strategies, but no studies were found that determined how academic...

Ixodes Scapularis SRC Kinase Is Required for Rickettsial Pathogen Survival in Ticks

Jeremy W. Turck
Anaplasma phagocytophilum is an obligate intracellular bacterium that causes disease in humans and animals. It is the causative agent for human anaplasmosis. A. phagocytophilum uses certain strategies to infect both vertebrates and invertebrates. It uses Ixodes scapularis ticks as a vector for spreading infection to other mammal species. This bacterium has a specific path for infection through the salivary glands of its vector host. It also suppresses certain functions such as the inhibition of apoptosis...

Inference and Estimation in Change Point Models for Censored Data

Kristine Gierz
In general, the change point problem considers inference of a change in distribution for a set of time-ordered observations. This has applications in a large variety of fields and can also apply to survival data. With improvements to medical diagnoses and treatments, incidences and mortality rates have changed. However, the most commonly used analysis methods do not account for such distributional changes. In survival analysis, change point problems can concern a shift in a distribution...

Advances in the Understanding of Sourcing and Fate of Pyrogenic Organic Matter in the Environment

Aleksandar Ivaylov Goranov
With higher occurrences of forest fires worldwide, there has been an increase in scientific interest surrounding the chemistry of pyrogenic organic matter (pyOM). The main structural components of pyOM, the condensed aromatic compounds (ConAC), exhibit intriguing physico-chemical properties and have been one of the main focuses of biogeochemical research. The overwhelmingly large number of scientific articles regarding pyOM and ConAC are guided by the assumption that ConAC in the environment are exclusively of pyrogenic origin,...

Self-Selected Maximum but Not Jogging Speed Decreases with Age in Male and Female Runners

Heather Hamilton
Introduction: Running velocity decreases with age, likely resulting from physiological and musculoskeletal changes associated with aging. Females experience a more rapid decline in physical performance during middle age than males, therefore it is important to consider separate-sex analyses when studying running biomechanics and running-related injury. The purpose of this study was to determine the relationship between age and different running speeds separately for female and male runners.

American Diplomacy Toward China, 1945-1948

Margo E. Horner
America's relationship toward China during the postwar years was aptly described by President Truman's summary of his China policy: “The role of this government in its relations with China has been subjected to considerable misrepresentation, distortion, and misunderstanding. Some of these attitudes arose because this government was reluctant to reveal certain facts…."8 Admiral William Leahy, Chief of Staff to presidents Roosevelt and Truman, acknowledged that America’s “post-war attitude toward the Government of China is completely...

Institutional Stretching: How Moroccan NGOs Illuminate the Nexus of Climate, Migration, Gender and Development

Shelby Mertens
The global migration crisis the world has experienced thus far is only the tip of the iceberg. As the earth’s temperature continues to warm and extreme weather conditions worsen, millions of people across the globe will be displaced, and women in particular will face more difficult challenges. What the climate migration literature fails to study is these longer-term impacts beyond sudden onset disasters. Governments and institutions will be forced to respond and adapt to the...

End-to-End Physics Event Generator

Yasir Alanazi
We apply generative adversarial network (GAN) technology to build an event generator that simulates particle production in electron-proton scattering that is free of theoretical assumptions about underlying particle dynamics. The difficulty of efficiently training a GAN event simulator lies in learning the complicated pat- terns of the distributions of the particles physical properties. We develop a GAN that selects a set of transformed features from particle momenta that can be generated easily by the generator,...

Automatic Generation and Novel Validation of Patient-Specific, Anatomically Inclusive Scoliosis Models for Biomechanics-Informed Surgical Planning

Austin Tapp
Scoliosis is an abnormal spinal curvature of greater than 10 degrees. Severe scoliotic deformities are addressed with highly invasive procedures: anterior or posterior spinal fusion approaches. This invasiveness is due, in part, to the constraints of current surgical planning, which utilizes computed tomography (CT) scans unable to discern spinal ligaments that are dissected to make the spine sufficiently compliant for correction. If localization of ligaments and soft tissues were achieved pre-operatively, corrective procedures could become...

Resident Safety During Disasters: Response to the COVID-19 Pandemic in Hampton Roads Area Nursing Homes

Tihara Richardson
The communal nature of long-term care facilities (LTCFs), and the population served which includes older adults often with underlying medical conditions, put those living in LTCFs at increased risk of infection and severe illness from COVID-19. The COVID-19 pandemic has further illuminated gaps in LTCFs disaster preparedness as they have lacked the resources necessary to contain the outbreak, including tests and personal protective equipment, and underpaid and undertrained staff.
