From Mind To Matter: Patterns Of Innovation In The Archaeological Record And The Ecology Of Social Learning, Kathryn Demps, Nicole M. Herzog, Matt Clark

Anthropology Faculty Publications and Presentations

Archaeology and cultural evolution theory both predict that environmental variation and population size drive the likelihood of inventions (via individual learning) and their conversion to population-wide innovations (via social uptake). We use the case study of the adoption of the bow and arrow in the Great Basin to infer how patterns of cultural variation, invention, and innovation affect investment in new technologies over time and the conditions under which we could predict cultural innovation to occur. Using an agent-based simulation to investigate the conditions that manifest in the innovation of technology, we find the following: (1) increasing ecological variation results …

Pharmacology Of Veratrum Californicum Alkaloids As Hedgehog Pathway Antagonists, Madison L. Dirks, Owen M. Mcdougal

Chemistry and Biochemistry Faculty Publications and Presentations

Veratrum californicum contains steroidal alkaloids that function as inhibitors of hedgehog (Hh) signaling, a pathway involved in the growth and differentiation of cells and normal tissue development. This same Hh pathway is abnormally active for cell proliferation in more than 20 types of cancer. In this current study, alkaloids have been extracted from the root and rhizome of V. californicum, followed by their separation into five fractions using high performance liquid chromatography. Mass spectrometry was used to identify the presence of twenty-five alkaloids, nine more than are commonly cited in literature reports, and the Bruker Compass Data Analysis software …

Utilizing A Structured Music Therapy Program For Adolescents With Anxiety And Depression, Amy Haagen

West Chester University Doctoral Projects

Anxiety and depression are two of the most common mental health issues that affect children and adolescents. It has been noted that twenty percent of adolescents will have a depressive episode or be affected by anxiety by the time they are 18 years old. Mental health issues affecting children and adolescents majorly impact all aspects of their lives, most notably academic success, behavior, growth, and development (Porter et al., 2017). Current treatments for mental disorders, including depression and anxiety, include pharmacological and psychotherapeutic treatments. In the adolescent population, there are conflicting opinions on the use of antidepressants due to risks …

Network Pharmacology And Molecular Docking Reveals The Therapeutic Mechanism Of Musa Acuminata Against Obsessive-Compulsive Disorder, Hasan Ansari, Prekshi Garg, K. S. Rashmi, Grisilda Vidya Bernhardt

Open Access archive

Network pharmacology integrates systems biology and bioinformatics to explore the intricate relationships among drugs, targets, diseases, and other molecular docking used to explore the effect of Musa acuminata against obsessive-compulsive disorder (OCD). OCD is a behavioral and mental neurological condition. The occurrence of patients with OCD has increased in recent times due to both genetic and environmental factors. Genetic factors involve variations in certain genes that give instructions for proteins that react to or transport the neurotransmitter known as serotonin which has been associated with an increased risk of OCD. Thus, the present study aims to establish the therapeutic properties …

Demystifying Multiple Sclerosis Diagnosis Using Interpretable And Understandable Artificial Intelligence, Krishnaraj Chadaga, Varada Vivek Khanna, Srikanth Prabhu, Niranjana Sampathila

Open Access archive

Multiple sclerosis (MS) is a dangerous illness that strikes the central nervous system. The body's immune system attacks myelin (an entity above the nerves) and impairs brain-to-body communication. To date, it is not possible to cure MS. However, symptoms can be managed, and treatments can be provided if the disease is diagnosed early. Hence, supervised machine learning (ML) algorithms and several hyperparameter tuning techniques, including Bayesian optimization, have been utilized in this study to predict MS in patients. Descriptive and inferential statistical analysis has been conducted before training the classifiers. The most essential markers were chosen using a technique called …

Open Access archive

This paper reemphasizes the importance of material consideration to design a low pull-in voltage MEMS switch. We have simulated different variants of a cantilever-based MEMS switch with variations in length, thickness, and material of the cantilever beam. The simulation study provides an understanding of a suitable cantilever design to achieve low operating voltage MEMS switch. We have further simulated the mechanical properties of these designs of the cantilever beam for a low operating voltage by computing the equivalent electrostatic force which is the input to the mechanical simulations performed using ANSYS.

Analysis Of The Magnetohydrodynamic Effects On Non-Newtonian Fluid Flow In An Inclined Non-Uniform Channel Under Long-Wavelength, Low-Reynolds Number Conditions, Manjunatha Gudekote, Rajashekhar Choudhari, Prathiksha Sanil, Hanumesh Vaidya

Open Access archive

This study utilises mathematical modelling and computations to analyse the magnetohydrodynamic (MHD) effects on non-Newtonian Eyring-Powell fluid flow in an inclined non-uniform channel under long-wavelength, low Reynolds number conditions. The governing equations are solved by applying slip boundary conditions to determine the velocity, temperature, concentration, and streamline profiles. The key findings show that the magnetic parameter dampens the flow rate. The relationship between the variable viscosity, velocity, and temperature is nonlinear. The wall rigidity parameter and axial velocity are directly proportional until a threshold. Increasing inclination angles distorts streamlines. The magnetic field alters concentration contours and thermal transport. MATLAB parametric …

Efficacy Of Lycium Barbarum (Goji Berry) Mouthwash For Managing Periodontitis: A Randomized Clinical Trial, Amee Sanghavi, Laasya Shettigar, Aditi Chopra, Ashmeet Shah

Open Access archive

Background: Removal of the microbial deposits (plaque and calculus) by performing effective scaling and root planing (SRP) is the fundamental step for managing periodontal disease (gingivitis and periodontitis). Various adjuncts in the form of mouthwash, gels, and toothpaste are also being used as adjuncts to SRP for managing periodontitis. Recently, Lycium barbarum (L. barbarum), commonly known as goji berry or wolfberry, has gained popularity for managing chronic inflammatory and infectious diseases. However, its efficacy in managing periodontitis has never been explored. Hence the present study aims to evaluate the efficacy of goji berry mouthwash compared to chlorhexidine mouthwash for managing …

Stories Of Dismantling Whiteness In Social Work Educational Spaces, Jeanean Mohr

West Chester University Doctoral Projects

Social work and higher education are rooted in systems of racism and exclusion and continue to operate as racialized spaces. As the social work profession grapples with its past and calls upon social work educators to support efforts to undo structural racism, paying attention to what is happening in educational spaces is essential. In this study, I examined the stories and tensions of White Social Work faculty engaged in efforts to dismantle whiteness in their classrooms, departments, and universities. Using narrative inquiry, I interviewed nine White faculty from different universities representing five regions across the United States. I explored their …

Classrooms, Hallways, And Peleas: The Violence And The Education Of Latino Students, Pamela Margolis

Building And Fostering Honors Communities: Lessons From Social Distancing, Anne Dotter, Kathleen King

National Collegiate Honors Council Monographs: Chapters

While scholars of online education have been developing ways to foster a sense of belonging in online spaces for years, many of us in honors were thrown into the deep end for the first time in March 2020. As a result, we are now able to see the potential of online practices in a way we could not previously. This chapter tells the story of how we came to see the value of virtual community made possible by digital technology as an invaluable complement to the in-person work of a twenty-first-century honors program. Before the Work from Home (WFH) era, …
