Siblings And Friendships With Women, Emily Norviel, Madison Oliver, Ava Amen, Grace Beckham

Science University Research Symposium (SURS)

Nuclear family relationships are some of the first and most foundational to an individual (Steinberg, 2023). Sibling relationships have an impact on the way an adolescent develops, regardless of birth order or sibling status, which influences the way the adolescent thinks and behaves (Feinburg et al., 2012). A negative sibling relationship can lead to issues such as school conduct problems, substance abuse, and low self-esteem (Feinberg et al., 2012). Friendships also play an important role in quality of life and social well-being of emerging adults. A high-quality friendship is defined by high levels of prosocial behavior, intimacy, and other positive …

Masculine And Feminine Facial Muscle Reactivity In Response To Observation, Caroline Avery, Micah D. Wilson, Waldron Collins, Sara Beam

Science University Research Symposium (SURS)

Individuals are consciously and unconsciously motivated by the need to fit in with social situations in order to maintain health and upkeep appearances (Hale et al., 2005). The literature has shown that individuals tend to change their facial expressions, particularly their zygomatic and ocularis muscles, in response to social situations, and they tend to exhibit an elevated heart rate (Brandenburg et al., 2022; Linnunsalo 2023). We predict females will exhibit these traits more due to their increased empathy and natural facial reactivity caused by the social pressures that dictate display rules of emotion by gender (Pollack, 1998; Adams Jr., 2014). …

Constructing Jain Goddess Padmavātī In Gujarati Literature, Venu Mehta

Monsoon: South Asian Studies Association Journal

Worship of the goddess Padmāvatī emerged more than a thousand years ago. This article explores three songs about her in Gujarati by Paṇḍit Vīrvijayajī (1773-1852). By analyzing the style and form of his work, one learns a great deal about devotional liturgies that commemorate goddess Padmāvatī’s protection of the Jina Pārśvanātha and, in turn, his protection of her.

Indigenous Stitch-Arts Of India: Tradition And Revival In A Global Age, Punam Madhok

Stitch art allows for the creative expression and economic support of countless women throughout India. This article examines four notable styles: chikankari, flora and fauna stitched in white thread on fine white cotton, rabari, the stitching of mirrors into colorful cloth, phulkari, resplendent flowery motifs sewn into shawls in Punjab, and kantha, Bengali patch work yielding quilts and seating mats. In addition to describing each technique, this article discusses how women have been economically empowered through this art by such organizations as Self-Help Enterprise (SHE) in Kolkata and Adithi, a women’s cooperative, in Bihar.

Assessing The Roles Of Myc And Egr1 In Endoderm Differentiation, Sadaf R. Shahebrahimi, Joseph Nguyen, Kyra Skye Thomas, Erick Spears

Science University Research Symposium (SURS)

The Wnt signaling pathway is evolutionarily conserved from fruit flies to humans. Strongly associated with development and embryonic morphogenesis, it is known to be required for early endoderm and later hindgut development in mammals. In adults, the Wnt signaling pathway is required for the proper maintenance of the intestinal epithelium and mutations in critical Wnt signaling pathway components are initiating events in the development of essentially all colorectal cancers. An important target gene whose expression is upregulated by Wnt signaling pathway activation is the oncogene MYC. This gene produces a transcription factor whose typical cellular role is to stimulate …

Does Birth Order Have An Effect On An Individual’S Conscientiousness?, Micah D. Wilson, Ashely Richmond, Emma Sells, Scovs Major, Waldron Collins

Science University Research Symposium (SURS)

Looking at familial relationships, specifically between sibling dynamics, has been focused on in many different angles in the field of psychology. Psychologists seek to understand the relationships between siblings, and how the relationships affect their bond, personality, and social life. Past studies have shown that siblings do tend to bounce off of each other, such as older sibling control having more of an effect in conflicts rather than in intimacy (Tucker & Updegraff). We hypothesized that the oldest siblings would clean up after themselves or not make a mess, middle children would clean up after themselves, the youngest would make …

H7n9 Influenza A Virus Transmission In A Multispecies Barnyard Model, Angela M. Bosco-Lauth, Anna Rodriguez, Rachel M. Maison, Stephanie M. Porter, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

Influenza A viruses are a diverse group of pathogens that have been responsible for millions of human and avian deaths throughout history. Here, we illustrate the transmission potential of H7N9 influenza A virus between Coturnix quail (Coturnix sp.), domestic ducks (Anas platyrhynchos domesticus), chickens (Gallus gallus domesticus), and house sparrows (Passer domesticus) co-housed in an artificial barnyard setting. In each of four replicates, individuals from a single species were infected with the virus. Quail shed virus orally and were a source of infection for both chickens and ducks. Infected chickens transmitted the virus to quail but not to ducks or …

Validation Of A Nutria (Myocastor Coypus) Environmental Dna Assay Highlights Considerations For Sampling Methodology, Anna M. Mangan, John A. Kronenberger, Ian H. Plummer

United States Department of Agriculture Wildlife Services: Staff Publications

Nutria (Myocastor coypus) is a semiaquatic rodent species that is invasive across multiple regions within the United States. Here, we evaluated a qPCR assay previously described for use in Japan for application across invasive populations in the United States. We also compared two environmental DNA sampling methodologies for this assay: field filtration of large volumes of water passed through filters versus direct sampling of small volumes of water. We validated assay specificity, generality, and sensitivity, compared assay performance between two independent laboratories, and successfully tested the assay in situ on a known wild population. The filtration method required …

Writing Statistical Methods For Ecologists, Amy J. Davis, Shannon Kay

United States Department of Agriculture Wildlife Services: Staff Publications

The Methods section is a key component of any ecology research publication containing detailed information on how the data were collected and analyzed. However, descriptions of which statistical methods were used and how they were applied can substantially vary and may not provide enough information for the analyses to be reproducible. Computational and statistical programming advances have allowed ecological researchers without a strong statistical or mathematical background to access and use increasingly complex statistical methods. Thus, statistical methods are written by and need to be accessible to researchers across a range of quantitative expertise. Poorly written Methods sections can incorrectly …

Invasive Frogs Show Persistent Physiological Differences To Elevation And Acclimate To Colder Temperatures, Jack R. Marchetti, Karen H. Beard, Emily E. Virgin, Erin L. Lewis, Steven C. Hess, Kwanho C. Ki, Layne O. Sermersheim, Adriana P. Furtado, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

The coqui frog (Eleutherodactylus coqui) was introduced to the island of Hawai’i in the 1980s and has spread across much of the island. Concern remains that this frog will continue to expand its range and invade higher elevation habitats where much of the island’s endemic species are found. We determined whether coqui thermal tolerance and physiology change along Hawai’i’s elevational gradients. We measured physiological responses using a short-term experiment to determine baseline tolerance and physiology by elevation, and a long-term experiment to determine the coqui’s ability to acclimate to different temperatures. We collected frogs from low, medium, and high elevations. …

Integrating Robotics Into Wildlife Conservation: Testing Improvements To Predator Deterrents Through Movement, Stewart W. Breck, Jeffrey T. Schultz, David Prause, Cameron Krebs, Anthony J. Giordano, Byron Boots

United States Department of Agriculture Wildlife Services: Staff Publications

Background Agricultural and pastoral landscapes can provide important habitat for wildlife conservation, but sharing these landscapes with wildlife can create conflict that is costly and requires managing. Livestock predation is a good example of the challenges involving coexistence with wildlife across shared landscapes. Integrating new technology into agricultural practices could help minimize human-wildlife conflict. In this study, we used concepts from the fields of robotics (i.e., automated movement and adaptiveness) and agricultural practices (i.e., managing livestock risk to predation) to explore how integration of these concepts could aid the development of more effective predator deterrents.

Non-Linear Modelling Of Internal Geophysical Waves, Joseph Cullen

Doctoral

Geophysical waves are waves that are found naturally in the Earth’s atmosphere and oceans. Internal waves, that act as an interface between fluids of different density are examples of geophysical waves. The system set-up will incorporate a model with a flat bottom, flat surface and internal wave. The system has a depthdependent current which mimics a typical ocean set-up and, as it is based on the surface of the rotating Earth, includes Coriolis forces. Using well established fluid dynamic techniques, the total energy is calculated and used to determine the dynamics of the system using a procedure called the Hamiltonian …

Towards An Improved Understanding Of The Concept Of Style And Its Implications For Textual Style Transfer, Somayeh Jafaritazehjani

Doctoral

The concept of linguistic style denotes that many aspects of text can vary while maintaining a same source core semantic meaning. For example, a message may be written in a formal or informal style. The textual style transfer problem aims at generating a paraphrase of a given text by modifying its style while preserving its content. To the best of our knowledge, within the literature on textual style transfer, there is no standard widely accepted definition of the concept of style. Moreover, very few works have investigated the characteristics of language styles. Therefore, previous research, as far as our knowledge …

Alternatives To Reducing Aviation Fuel-Burn With Technology: Fully Electric Autonomous Taxibot, Denzil Neo

Student Works

Aircraft taxiing operations in the aerodrome were identified to consume the most jet fuel apart from the cruise phase of the flight. This was also well supported by various research associating taxi operations at large, congested airports, with high jet fuel consumption, high carbon emissions, and noise pollution. Existing literature recognised the potential to address the environmental issues of aerodrome taxi operations by operating External or Onboard Aircraft Ground Propulsion Systems (AGPS). Designed to power aircraft with sources other than their main engines, external Aircraft Ground Power Systems (AGPS) have shown the potential to significantly cut jet fuel consumption and …

Evaluation Of The Photon Contributions To The Solar Energy Conversion For Organic Luminescent Down-Shifting Liquid Beam Splitters In Hybrid Photovoltaic-Thermal (Pvt) Applications Using Raytracing Monte Carlo Simulations, Kenneth Coldrick

Articles

A hybrid photovoltaic-thermal (PVT) system combines photovoltaic (PV) and photo-thermal (PT) energy collection into a single structure, enhancing the potential to achieve greater solar energy conversion efficiencies. Such enhanced efficiencies can result in greater economic returns and could promote a larger uptake of PVT devices in cold and temperate climate countries. Through the utilization of a Monte Carlo ray-tracing model, this work provides new insights into the optical, electrical, and thermal characteristics of PVT devices. In particular, the work focuses on evaluating the behaviour of novel luminescent imidazole-phenanthroline-based working fluids that were previously experimentally investigated as liquid spectral beam splitters …

Determining Child Sexual Abuse Posts Based On Artificial Intelligence, Susan Mckeever, Christina Thorpe, Vuong Ngo

Conference papers

The volume of child sexual abuse materials (CSAM) created and shared daily both surface web platforms such as Twitter and dark web forums is very high. Based on volume, it is not viable for human experts to intercept or identify CSAM manually. However, automatically detecting and analysing child sexual abusive language in online text is challenging and time-intensive, mostly due to the variety of data formats and privacy constraints of hosting platforms. We propose a CSAM detection intelligence algorithm based on natural language processing and machine learning techniques. Our CSAM detection model is not only used to remove CSAM on …
