American Public Opinion And Media Representations Of The Crimean War (1853–1856), Anurag Shah

The Journal of Purdue Undergraduate Research

During the Crimean War (1853–1856), France and Britain sided with the Ottoman Empire to curb Russian expansion. Though an ocean away, the American public was not only aware of this conflict but often held strong opinions on the war and its participants. American media representations of the Crimean War are indicative of this, and a systematic examination reveals some significant trends in reporting, aligning closely to and providing nuance for larger trends in American history.

The most significant trend in newspaper reporting of the Crimean War was a North-South geographical divide. Northern states supported Britain and France throughout the conflict, …

Where To Build Food Banks: A Machine Learning Approach, Gavin Ruan

The Journal of Purdue Undergraduate Research

Over 44 million Americans currently suffer from food insecurity, of whom 13 million are children. Food insecurity has been shown to cause a wide range of both physical and developmental issues. Across the United States, thousands of food banks and pantries serve as vital sources of food and other forms of aid for food-insecure families. By optimizing food bank locations, food banks and their resources would become more accessible to families who desperately require it. The aim of this paper is to build a machine learning framework that is able to optimize food bank locations and to consider factors such …

Predictive Maintenance Analysis Of Turbofan Engine Sensor Data, Stanley A. Melkumian

Identification Of Conserved Eukaryotic Gene Products In Novel Mycobacteriophage, Brandon Mar, Jade Coxon, Lily Esterline, Sydney Clifford, Gabriella Burke, Mallory Motz, Alaina Gartner, Kioni Bush, James Lin, Lizzie Adams, Sophia Palant

The Journal of Purdue Undergraduate Research

Bacteriophage, a type of virus that infects bacteria, was discovered 100 years ago, initially isolated with a plaque assay in the 1940s. A mycobacteriophage is a subtype of bacteriophage that specifically infects mycobacteria. Since the introduction of DNA technologies and efforts to identify a plethora of bacteriophages, over 10,000 bacteriophages have been identified with 1,500 sequenced. Bacteriophage discovery has aided in genetic editing techniques, the development of synthetic biology tools, and disease treatment. However, to be able to expand on these capabilities, there is a need to identify more bacteriophages and sequence the genomes of these viruses, as they outnumber …

The Influence Of Soil Properties And Land Management On Soil Porewater Chemistry, Bethany Kettleborough

The Journal of Purdue Undergraduate Research

Soil water dynamics influence vegetation health, soil geochemical reactions, and stream chemistry. Water dynamics can be controlled by soil type and land management. It is important to understand water movement due to its influence on soil weathering, microbial activity, and nutrient transport. Water movement can be investigated using water stable isotope variability as a tracer. The purpose of this ongoing study was to analyze stable isotopes and dissolved ions in prairie and agricultural land management sites in Nebraska and Illinois.

"Wedded In The Association": Heteroglossic Form And Fragmentary Histiography In Nick Joaquin's Almanac For Manileños, Vincenz Serrano

Kritika Kultura

Almanac for Manileños (1979) by Nick Joaquin (1917-2004) is “a calendar, a weather chart, a sanctoral, a zodiac guide, and a mini encyclopedia on the world of the Manileño.” Undergirded by Mikhail Bakhtin’s concept of heteroglossia, Walter Benjamin’s montage method in writing history, and Reynaldo Ileto’s notion of non-linear emplotment, the essay engages with the Almanac’s calendars and essays and offers four claims. Firstly, although multiple genres embedded in the Almanac—which include, apart from the abovementioned, horoscopes, recipes and light verse—stratify the text, temporal associativeness offers a sense of cohesion. Secondly, the formal strategy of the calendars—typified by correspondence and …

Letting It Flow: A Phenomenology Of Water In The Age Of Modern Technology, Remmon E. Barbaza

Kritika Kultura

This essay seeks to initiate a phenomenology of water in the age of modern technology within a Heideggerian framework. Insofar as it holds sway as the essence of modern technology, Ge-stell (enframing) blocks the appearance of water as water. Instead, like most other “natural resources,” water appears as the resource that is extracted, manipulated, and made readily available for universal distribution and instant consumption, but detached from its origin in earth and sky. A disruption in the handiness of water, however, such as is occasioned by water shortage or massive flooding, offers the possibility of inviting human beings to recover …

Motivated by these challenges, this paper proposes an integrated decision-making framework to tackle the closed-loop supply chain network redesign (CLSCNR) problem. The proposed framework is formulated as a mixed-integer programming (MIP) model, specifically tailored for the glass industry. The forward supply chain …

Possibility Above Actuality In Sartre’S Ontology Existential Thoughts On Education, James M. Magrini

Turning Toward Being: The Journal of Ontological Inquiry in Education

Systematic philosophies and practices of education, more often than not, tend to define the nature of the human being in terms of an immutable essence. For example, a manipulable organism within the learning environment or empty vessel to be filled with the knowledge it lacks. Systematic education, for the most part, is based on the uncritical acceptance of such antecedent ontological/biological conclusions regarding human being; views which leaves little room for the exploration and experience of human freedom. In response to this aforementioned problem, the pressing issue grounding this essay, which educators seeking to better serve their students should consider, …

Virtual Reality Exposure Therapy For Social Anxiety In Adolescents, April Fohrman

Counselor Education Capstones

Exposure therapy has been around for decades and is still proving to be a robust, evidence-based treatment modality for several psychological issues. Imaginal exposure (vividly imagining a feared object, situation, or activity) and in vivo (directly experiencing the real fear or situation) are the traditional modes of exposure intervention. Although these treatments have shown that they work, they can also be time-consuming, expensive, or even impossible to replicate. A newer exposure therapy combines traditional imaginal therapy with in vivo therapy, but virtually.

This combination creates a middle ground where exposures to situations or fears can be increased or decreased virtually …

Performance Prediction For Hub-Based Swarms, Puneet Jain

Theses and Dissertations

Optimization problems lie at the core of improving performance in various tasks, ranging from day-to-day work scheduling to coordinating robots in a warehouse fulfillment center. Distributed swarm systems provide a robust and adaptive solution approach to many optimization problems. Instead of using one really sophisticated agent, multiple smaller less sophisticated agents can provide the flexibility to evaluate more options and still provide a "good" answer. This dissertation uses graphs to model, analyze, and simulate swarm behavior, primarily to predict the time-to-converge (TTC) and success probability. First, we use a bipartite model for the distributed best-of-N problem, and show how the …

Assessing Coincidence Of Satellite Acquisitions And Flood Events To Predict Suitability For Flood Map Synthesis, Lyle Dale Prince

Theses and Dissertations

Flooding is a global problem that impacts people, communities, and governments every year. Better understanding of flooding in an area can enable improved emergency response before a flood hits. Flood maps are a crucial tool to translate what for most is an abstract flow, into a more understandable and actionable representation of who and what are at risk. Satellite based flood maps are a useful tool that has potentially global applications. We developed methods to determine which areas are suitable for generating satellite-based synthetic flood maps. For our processes we used Forecasting Inundation Extents using REOF analysis (FIER): a data-driven …

A Mechanistic Study Of Silicon Nanocrystal Formation Via Solid State Synthesis, Katherine Mccarthy Weinfurter

Dissertations and Theses

Silicon nanocrystals (SiNCs) show promising physiochemical properties that could be used in industrial applications. The production of SiNCs through solid-state synthesis is ideal due to relatively low cost of equipment and chemical reagents, as well as the ability to scale-up production. A widely known and commonly used precursor previously used in solid-state synthesis for SiNCs, hydrogen silsesquioxane (HSiO_1.5), was discontinued in chemical manufacturing, which has led to researching alternative precursors (or starting materials). We have identified that there is a gap of knowledge related to producing these precursors, as well as the mechanistic understanding of the chemical reactions …

A Comparison Of Rfssw And Rsw For Automotive Manufacturing, Damon Michael Gale

Theses and Dissertations

Historically, automotive body panels have been made of steel and joined by a process called resistance spot welding (RSW). However, in efforts to reduce vehicle weight to improve the energy efficiency of the vehicle, automotive manufactures have begun substituting aluminum in place of steel. While aluminum can be joined with RSW, a myriad of challenges arise from doing so. These challenges result in less consistent weld quality and accelerated electrode wear. Refill friction stir spot welding (RFSSW) is an emerging joining technology that could replace RSW as it is believed to be capable of creating superior joints in thin sheet …

Non-Compete Clauses Mysteriously Appearing Out Of Thin Air: The Catastrophic Flaws Of Inevitable Disclosure Doctrine In The New Ftc Non-Compete Rule And Beyond, Bradford P. Anderson

Southern Illinois University Law Journal

The Federal Trade Commission (FTC) recently adopted a new regulation that prohibits non-compete clauses for employees (Non-Compete Rule). Simultaneously, the FTC allowed the inevitable disclosure doctrine to continue in existence, even though such doctrine is tantamount to a non-compete clause. Under the inevitable disclosure doctrine, an employer posits that an employee will be unable to abide by her/his confidentiality obligations, and therefore unable to resist use and disclosure of proprietary information at an alternative employer. As a result, prescient, mind-reading judges portend future conduct under the inevitable disclosure doctrine and can issue an order banning or restricting future employment, thereby …
