Semantic Search Using A Similarity Graph, Lubomir Stanchev

Computer Science and Software Engineering

Given a set of documents and an input query that is expressed in a natural language, the problem of document search is retrieving the most relevant documents. Unlike most existing systems that perform document search based on keywords matching, we propose a search method that considers the meaning of the words in the query and the document. As a result, our algorithm can return documents that have no words in common with the input query as long as the documents are relevant. For example, a document that contains the words “Ford”, “Chrysler” and “General Motors” multiple times is surely relevant …

Role Of Disorder In Finite-Amplitude Shear Of A 2d Jammed Material, Nathan C. Keim, Paulo E. Arratia

Physics

A material’s response to small but finite deformations can reveal the roots of its response to much larger deformations. Here, we identify commonalities in the responses of 2D soft jammed solids with different amounts of disorder. We cyclically shear the materials while tracking their constituent particles, in experiments that feature a stable population of repeated structural relaxations. Using bidisperse particle sizes creates a more amorphous material, while monodisperse sizes yield a more polycrystalline one. We find that the materials’ responses are very similar, both at the macroscopic, mechanical level and in the microscopic motions of individual particles. However, both locally …

The Affect Of Versioned Package Design On Various Demographics, Howard E. Vogl, Colleen L. Twomey, Kristen Dang, Alexis B. Kelsey

Graphic Communication

This study challenged the concept of a single best package design for food products. Research found that typography played a crucial role in the consumer’s perception of the quality and the value of a product. It was also found that, based on the consumer’s purchasing intention, the use of type or graphics on a package could have either a positive or a negative affect on consumer perception of product value and quality. In addition, this study pointed out that these variables require careful testing in the marketplace, which can only be achieved in package designs that can be economically tested …

Detection Of Catecholamines Produced In Planktonic P. Aeruginosa And S. Aureus Treated With Adult Bovine Serum, Jorge A. Serrano, Anil Serrano, Shaleni Singh, Jaime Fuentes, Robert Crawford Dr., Rivkah Isseroff, Thomas Peavy

STAR Program Research Presentations

Bacterial biofilms play a critical role in inducing and sustaining chronic wounds that are serious health threats. Bacterial biofilms can also be found on medical prosthetics and implants that sustain infections in patients and cause life threatening situations. Bacteria self-produce these sticky extracellular substances termed a biofilm which help them to adhere to each other forming a community of microorganisms. One of the major issues is that biofilms have antimicrobial characteristics and provide protection from the immune system; biofilms are found in over 80% of human bacterial infections. Formation of a bacterial biofilm occurs when an individual (planktonic) bacterial cell …

Subversion Of The Transgender Gaze Through Cisnormativity, Debra Beight

sprinkle: an undergraduate journal of feminist and queer studies

This paper analyzes Halberstam’s interpretation of the transgender gaze as it applies to the character portrayal of Brandon Teena in the film Boys Don’t Cry. An oppositional approach examines the idea of a cisgender gaze that compromises the subjectivity of not only the character of Brandon but extending to dismissiveness towards trans identity as a whole. Dissecting the reveal scene from the film highlights Halberstam’s process of the transgender gaze and allows for a focus on cisgender interpretation and demands that illustrate cisnormative expectations on trans bodies and behaviors. Connecting these demands is the concept of abjection as described by …

The Case Of M.C. – An Argument For Legal, Medical, And Social Recognition Of Ambiguity, Debra Beight

sprinkle: an undergraduate journal of feminist and queer studies

This paper is an examination of the interconnectedness of juridical, medical, and social constructs surrounding intersex/DSD (Difference/Disorder of Sex Development) sex assignment surgeries. Looking at a pending court case involving a child that was in state custody at the time of their sex assignment surgery, we can observe the influences of the medical industry’s tendency to treat intersex conditions like disabilities, as sites of therapeutic interventions. These pathologized intrusions become government-sanctioned interventions that are supported by, and in turn bolster, societal expectations of conformity and normalcy.

Effects Of School Curriculum On Sexual Health, Emma Sturm

sprinkle: an undergraduate journal of feminist and queer studies

Surveys indicate that, when asked directly, women have positive perceptions of their vaginas and perceive vaginal, sexual, and reproductive health as important. However, when asked about their actual habits relating to vaginal health, women’s answers seemed to suggest the opposite. This disconnect between perceptions and practice suggest there may be some societal influence keeping the women from carrying out their health maintenance as well as they would like to. This paper examines the role schools play in controlling women’s sexuality, which may be contributing to the lack of accessibility to vaginal, sexual, and reproductive health.

Sexual Assault: Whose Fault Is It Anyway In A Rape Culture?, Grace Pappas

sprinkle: an undergraduate journal of feminist and queer studies

Sexual assault has recently gained attention as a prevalent issue in American culture, particularly on college campuses. While in some places much is being done to raise awareness and end this form of gendered violence, too often fingers are pointed at possible causes rather than intertwined as hands held together in the fight against this injustice. Through an examination of empirical research, it is clear that the issue of sexual assault stems from and is perpetuated by a rape culture, a culture in which we are all a part. This paper argues that if we are to fight sexual assault, …

Bending The Binary: Lgbtq Sex Workers’ Gender Presentations, Nicole White

sprinkle: an undergraduate journal of feminist and queer studies

The lived experiences of LGBTQ sex workers are largely unknown. Of the few representations of LGBTQ sex workers in media and academia, most are shrouded in inaccurate and dehumanizing stereotypes. Through qualitative interviews with eight LGBTQ sex workers in Denver and Boulder, Colorado, this thesis attempts to portray an accurate view of the way LGBTQ sex workers negotiate their gender and sexual identities. LGBTQ sex workers were found to balance their queer and trans identities and presentations with clients’ perceived desires for hegemonic gender presentations, maintaining a unique blend of authentic presentation and marketability.

Nonconsensual Pornography, Hannah Mcneil

This paper addresses the issue of nonconsensual pornography and its effects on victims; a case study involving an in-depth interview of a participant who offers a personal perspective on the struggle of coping with the damaging aftermath of revenge porn. This research aims to examine how this type of exposure and online sexual harassment is harmful to its victims and seeks to raise awareness for this form of harassment in the digital age.

Rational Emotion, Feminine Professionalism, And Cooperative Success: Women Scientists In Star Trek: Voyager As Challenges To The Dominant Ideology, Kiran Mccloskey

sprinkle: an undergraduate journal of feminist and queer studies

This article considers Star Trek: Voyager’s portrayal of women in the sciences through the lens of Eva Flicker’s 2003 review of scientific women throughout film and television from 1927 to 1999. Two core divergences in Star Trek: Voyager are identified: the absence of constraining dualities such as the rational/emotional and professional/feminine divisions, and the lack of isolation experienced by the female scientists. Such a representation would have positive effects on female viewers according to the sociological interpellation process model, which is supported by testimony and correspondences with multiple fans.

Immobilization And Phytotoxicity Reduction Of Heavy Metals In Serpentine Soil Using Biochar, I. Herath, P. Kumarathilaka, A. Navarantne, N. Rajakaruna, M. Vithanage

Biological Sciences

Purpose

Serpentine soils derived from ultramafic rocks release elevated concentrations of toxic heavy metals into the environment. Hence, crop plants cultivated in or adjacent to serpentine soil may experience reduced growth due to phytotoxicity as well as accumulate toxic heavy metals in edible tissues. We investigated the potential of biochar (BC), a waste byproduct of bioenergy industry in Sri Lanka, as a soil amendment to immobilize Ni, Cr, and Mn in serpentine soil and minimize their phytotoxicity.

Materials and methods

The BC used in this study was a waste byproduct obtained from a Dendro bioenergy industry in Sri Lanka. This …

The Effects Of Slow-Release Aluminum Sulfate On Bloom Color Of Hydrangea Macrophylla, Patrick James Edziak

Horticulture and Crop Science

Hydrangea macrophylla is a common greenhouse crop typically produced for the late winter and spring holidays. Most varieties are capable of producing either pink or blue flowers depending on aluminum content and pH of the growing medium. The goal of this experiment was to examine the effects of new controlled-release aluminum sulfate products on bloom color. This new product was applied as a topdress and a pre-plant incorporated mix using two different manufacturer recommended rates. Results were directly compared with those produced using a traditional water-soluble aluminum sulfate drench application. Controlled release aluminum sulfate was found to be at least …

Large Dynamic Range Amplifier Plus Adc, Ted Hsueh

Electrical Engineering

Nerve and muscle signal sampling proves difficult because of the large difference in magnitudes. Muscle signals loom a hundred or even a thousand times bigger and can hide the nerve signals. The Large Dynamic Range Amplifier plus Analog to Digital Converter (ADC) allows one device to retrieve both muscle and nerve signal information. The device has two parts: the ability to take high-resolution data from tenths of microvolts to several millivolts and filter out environmental noise, such as 60 Hz of electrical power lines or electro galvanic signals. This gives the ability to read muscle and nerve signals using one …

For Those On Glass Cliffs: The Nature Of Women In Power As Explored Through Frozen, The Abramson Effect, And "Let It Go, Raelissa Glennon-Zukoff

sprinkle: an undergraduate journal of feminist and queer studies

This paper seeks to explore the link made by Deborah Spar in her recently published piece The Ambramson Effect: Tales of Women Who Topple From Power between the effects of the glass ceiling and glass cliff effects on women in the topmost positions in American businesses, organizations, and corporations and the ascension to power of Queen Elsa in the Disney motion picture Frozen. By incorporating media reports on merchandising and animation, as well as scholarly research, this paper places Spar's theory into a more accessible space. Furthermore, by referencing the lyrics to the feature power ballad from the animated film, …
