The Effectiveness of Uzarigenin as an Antiseptic against Staphylococcus aureus
Get PDFTo determine the effectiveness of uzarigenin on S. aureus, the agar disk diffusion method was first completed to study the cytotoxicity effect of uzarigenin directly on the bacteria. A cytotoxicity assay was then completed to test the cytotoxicity of the uzarigenin on the human epithelial fibroblasts themselves. After, a TCID50 assay was used to test for a preventative dose of uzarigenin against S. aureus to determine at what dilutions the uzarigenin can protect the cells from infection at least 50% of the time. It was found that there was an average 8.5 mm zone of inhibition compared to a standard 26.4 mm zone of inhibition by tetracycline. Since there may be different diffusion rates, S. aureus may be resistant to uzarigenin. It was also found that the uzarigenin caused cytopathic effects (CPE, changes in the host cell morphology due to infection) on the human epithelial fibroblasts up until a dilution of 10^-6. Additionally, the 10^-6 and 10^-9 dilutions of uzarigenin were effective in combatting an infection from S. aureus, leaving little to no traces of cytopathic effect. However, dilutions further than 10^-9 seemed to be too diluted to combat an infection, which resulted in CPE in all or most of the wells. Furthermore, the preventative dose for uzarigenin against S. aureus was found to be 10^11.2. In conclusion, uzarigenin may be able to be used as an antiseptic
The Great Narrative: The Evolution of State Censorship in Soviet Era Museums
Get PDFBefore the Revolution of 1917, Russian museums were created by and for the ruling elite. Strict limitations on attendance and what objects could be viewed by what persons defined Russia’s imperial era. After the Revolution, the Soviet Union began to open its museum doors and create more museums by and for the working-class people and their struggle. Starting in the 1920s, a “Great Narrative,” as I call it, came into being that shaped the themes and missions of each museum in the Soviet Union. The Great Narrative was developed by Soviet leaders and the censorship bureau and often changed regularly, requiring frequent museum renovations. While museum attendance flourished and millions of objects went on display, the Great Narrative of the Soviet Union was constantly changing, therefore the museum network was under revision at all times from the beginning to the end of the Soviet Union. The revision of the Great Narrative led to large amounts of censorship in Soviet era museums, however this censorship was also not stagnant. Starting in 1917 and through the 1980s, Soviet museums were subjected to comprehensive state censorship, whether about the overall narrative being told or the objects themselves. However, the censorship was not stagnant and increased or decreased depending on the Soviet leader of the time and what policies and narratives were being developed under their leadership
Untitled: Into the Mind of Margaret Sutton
No full textThis semester students working on the New York painter Margaret Sutton \u2726 were struck by the number of works the artist left untitled. When the works came to Mary Washington in 1993, gallery staff catalogued hundreds of untitled paintings, drawings, and sketches using descriptive terms. A daunting task considering Sutton\u27s fantastic imagery and the number of works to consider! Without a title the viewer is left to imagine and create significance on their own. Sutton encourages us, over and over, to be creative and playful, to check our experiences and define them within a fantastic environment that offers little certainty. The mind of Margaret Sutton remains a mystery, but the artist opens a door for our own minds to search for meaning. Untitled: Into the Mind of Margaret Sutton is the spring 2021 exhibition produced by students in ARTH 317: Laboratory in Museum Studies, and exhibited in the Phyllis Ridderhof Martin Gallery at UMW from April 8 through August 1, 2021, and in the online exhibition. http://margaretsutton.maochclasses.org/2021-into-the-mind
Oda a la Bicicleta
No full textMy Project is inspired by the work of Chilean writer Pablo Neruda’s Odas. His remarkable work was awarded the Nobel Prize for Literature in 1971. Neruda’s Odes are inspired by all things that surrounded him. He found beauty in the simplest things, such as an artichoke, a lemon. His work aims to portray an enthusiastic approach from the lenses of positivism and realism. My inspiration was my bicycle. My child’s memories around it and all the happiness that I had because of it. I hope you enjoy it
Problematic Approaches in Communication Towards People with Disabilities
Get PDFThrough this video essay, I am hoping to draw attention to the problematic approaches in communication towards people with disabilities, but specifically invisible disabilities. In this video essay, I talk about the harmful effects of using war metaphors when talking about chronic illnesses, why inspiration porn is problematic, and how COVID-19 has impacted the rhetoric when talking about disabilities and chronic illnesses. We should all be working towards creating an environment that doesn\u27t negatively impact or burden those suffering with chronic illnesses or disabilities and I hope this video essay is just the start of the research you do to better support your chronically ill and disabled loved ones
Preparing Pre-service Teachers for Success in Linguistically Diverse Science Classrooms
No full textOne in 10 students in our public schools are emergent bilingual students (EBs), tasked with learning science even as they are still developing their English (National Center for Education Statistics, 2019). It is becoming more likely, therefore, that all science teachers will have the opportunity at some point in their careers to teach science to students who are still learning the language of instruction
Conjugation by Circulant Matrices in Non-commutative Cryptography
Get PDFWe introduce a procedure in which two trusted individuals, Alice and Bob, may share a secret matrix K from the non-abelian general linear group of matrices. In this procedure, the matrix K is concealed from an eavesdropper, Eve, by a sequence of conjugations by elements from a pre-determined abelian subgroup of the general linear group. We demonstrate that the group of invertible circulant matrices is one abelian subgroup that may be able to withstand a brute force attack. To analyze this we need a technique to determine the order of this group, and to do this we make use of a well-known isomorphism between the ring of circulants over a finite field and a quotient of the ring of polynomials over a finite field. After we show empirically that the order of the group of invertible circulants increases exponentially in dimension n with degree q of the field fixed, we will give a universal lower bound on the order of this group to prove this mathematically as well
On Primary Matter & Causality: An Investigation into The Nature of Aristotelian Ontology
Get PDFThis paper investigates the problems which arise from integrating a notion of prime matter into Aristotle\u27s works. After an analysis of both The Metaphysics and The Physics, it becomes clear that prime matter arguments do not adhere to Aristotle\u27s ontological hierarchy. After exposing the flaws of the traditional prime matter argument, the extended prime matter argument, and the prime matter as a principle of change argument, a new interpretation of how Aristotle could respond to this problem of prime matter is presented. Aristotle\u27s Final Cause serves to be a better candidate for the position which other scholars have granted prime matter primarily because it adheres to Aristotelian ontology
Body Language: Avatars, Identity Formation, and Communicative Interaction in VRChat
Get PDFWhat meanings do actors attach to their avatars in virtual reality platforms? How does a person’s relationship with their selected avatar impact their communications with other persons in virtual reality settings? In this thesis, Montemorano seeks to answer these questions through qualitative, ethnographic fieldwork that she conducted in 2019 in the virtual reality space known as VRChat, and in connection with anthropological literature on embodiment, sociality, and personhood. This thesis details the author’s research findings, provides a brief historical background on virtual worlds and avatars, and discusses several noteworthy ethnographic studies of virtual worlds such as Boellstorff’s Coming of Age in Second Life. The result is a blend of pertinent vignettes with scholarly analysis of feminist and posthumanist theories of performativity, virtualism and play. Montemorano stresses the distinctiveness of anthropology in studying virtual worlds, owing in particular to the discipline’s emphasis on the social constructedness and performativity of identity and its methodological commitment to participant observation. By connecting her original research to broader anthropological theories and concepts, Montemorano hopes to spark thought on how digital platforms and virtuality potentially grant actors the ability to subvert traditional identity categories and create new and unexpected affinities
Resiliency and Resources for Students Affected by Adverse Childhood Experiences
Get PDFEducating today’s youth has many challenges, but the ever-growing population of students who have experienced adverse childhood experiences poses the greatest difficulty to educational professionals due to the lack of resources and knowledge available. Many students who have experienced adverse childhood experiences have unwanted behaviors that educators are not equipped to deal with due to the lack of knowledge of trauma-informed care. Trauma informed care needs to be integrated into all schools. This will allow equal access to public education for all students, even those seen as troubled due to circumstances beyond their control.
There are many factors that can influence the resiliency and social-emotional health of students who have been affected by adverse childhood experiences. As schools begin to recognize the symptoms of trauma and educate staff members on this recognition, schools will begin to see more students succeed. The strategies to deal with students who have been impacted by trauma need to be easily available to educators to allow all students to have access to a positive school climate that is conducive to learning, not just students unaffected by trauma. Often, students affected by ACEs are seen as problems with no solutions. This mindset needs to change, just as the mental health of our youth is ever-changing.
The number of children exposed to adverse childhood experiences is increasing at an alarming rate. Children who have been affected by adverse childhood experiences have faced varying degrees of abuse throughout their childhood to include sexual, mental, physical, emotional and substance abuse which can significantly alter the health and well-being of a child (Soleimnapour, Geirerstanger, & Brindis, 2017) (Sciearaffa, Zeanah, P., & Zeanah, C, 2018). The negative effects of adverse childhood experiences and the lack of resources available to students exposed to adverse childhood experiences are disheartening. The integration of trauma informed care in our schools needs to become a priority if the desire for all students to succeed continues to remain at the forefront of our policymakers.
Along with the integration of trauma-informed care, resources such as screening inventories measuring a student’s resiliency or the number of adverse childhood experiences, a child has experienced need to be available to use with students suspected of having been exposed to ACEs. Once educated in trauma-informed care, educators will be more apt to recognize the signs of trauma within a child. Educators can utilize the screening inventories to guide future interactions with students who have been affected by trauma
