A Pentadic Rhetorical Analysis Of Malala Yousafzai’S Address To The United Nations’ Youth Assembly, Alexis Rehm

Pepperdine Journal of Communication Research

This paper is a rhetorical criticism of Malala Yousafzai’s 2013 address to the United Nations Youth Assembly using Kenneth Burke’s pentad. Malala Yousafzai’s address was delivered less than one year after surviving an assassination attempt by the Taliban. The address reframes access to education as a shared moral responsibility rather than a personal or political issue. By analyzing the scene, act, agent, agency, and purpose, this analysis shows how Malala constructs rhetorical authority through personal narrative, forgiveness, and moral appeal. Her speech positions education as a universal human right and challenges global audiences to move from sympathy to accountability.

Click Reactions With Surface-Bound Phosphonate Films Toward An Electrocatalytic System For Carbon Dioxide Reduction, Iaroslavna Kovalenko, Emma J. Goehner, K. Nicole Crowder

Research and Creativity Symposium

One way to electrochemically reduce CO₂ is to use modified electrode surfaces with bound transition-metal electrocatalysts. Optimal conditions for modifying copper surfaces with a 1.0 mM solution of (2-azidoethyl) phosphonic acid in acetone have been identified, forming a self-assembled monolayer (SAM) via the tethering by aggregation and growth (T-BAG) method. The SAM protects the copper electrodes from oxidation or side reactions on the copper surface. The copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction between the terminal azide group on the phosphonate and the terpyridine ligand has been successfully carried out on the copper surface. This terpyridyl ligand was then used …

The Impact Of Language On The Academic Experience Of Multilingual Students, Daniela Duran Aguilar

2026 Undergraduate Research Showcase

Multilingual students are an important part of higher education in the United States, and that is why their academic experiences matter. In 2022, 33% of students in U.S. universities had first-, second-, or third-generation immigrant backgrounds (Feldblum et al., 2024, p. 14), and 4% of students were international students (“Higher Ed Immigration Portal,” 2024). Research has investigated the perspectives of multilingual students through interviews (e.g., Dykema, 2024; Tavares, 2023). This study contributes to this body of research by asking multilingual students from Boise State to describe the benefits, challenges, and support they experience in college.

Words That Work: Healthcare Providers’ Acceptability Of Aba Terminology, Marisa A. Hurlock

Thesis Projects

Effective collaboration between behavior analysts and healthcare providers depends on a shared understanding. This study explored how healthcare professionals perceive technical versus plain-language ABA terminology. Healthcare providers (n = 44) rated 10 common ABA terms and their plain-language counterparts across clarity, acceptability, comfort, and likelihood of use. In addition, participants completed a paired-choice procedure in which they selected their preferred terminology for each term pair. Plain-language terminology was generally rated more favorably across all four dimensions and was preferred by approximately 70.6% of respondents. However, this pattern was not consistent across all terms, as several technical terms (e.g., negative …

Automatic Determination Of Mechanical Properties From Molecular Dynamic Stress-Strain Curves Using Regression Fringe Response, Josh Kemppainen, Tristan Muzzy, Travis Wavrunek, Gregory Odegard

Michigan Tech Publications

Molecular dynamics (MD) simulations have become a powerful tool for studying polymers, designing new materials, and composites. Mechanical behavior in MD simulations are typically evaluated through stress-strain curves. However, MD-generated stress-strain curves are often obscured by thermal noise from atomic vibrations. This noise complicates the reliable derivation of mechanical properties and hinders objective and reproducible analysis. The noise in the stress-strain curves has been removed by using a Butterworth low-pass filter, enabling clearer interpretation of stress-strain data. Building on this, a novel analysis framework the Regression Fringe Response (RFR) is introduced to systematically determine the Young's modulus, yield strength, and …

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary

Chemistry and Chemical Engineering Student Publications

Cyanines are highly conjugated molecules with useful properties, such as ease of aggregation and fluorescence. In this project, they were incorporated into an acrylamide-based nanogel made through organic synthesis to exploit these properties for controlled drug delivery. Exposing the nanogel to nearinfrared (NIR) light causes it to react with reactive oxygen species (ROS), forming an unstable intermediate. The intermediate splits into two fragments, releasing the nanogel's cargo.1 The cargo, temozolomide, is an alkylating agent which can be used to disrupt the DNA of cancer cells.
