How Should Scientists Act? Assessing Public Perceptions Of Scientists And Scientific Practices And Their Implications For Science Communication, Thomas G. Safford, Emily H. Whitmore

Faculty Publications

Is how science is conducted legitimate? Are scientists trustworthy? Whether the public answers “yes” to these questions is critical for science communicators. We explore how social factors affect public perceptions of the practice of science, and then test how those beliefs relate to views about how scientists engage with the public and policy making. Our results show that political ideology and religiosity affect these views. However, more importantly, respondents’ concerns about the integrity of the scientific process are the strongest predictor of views about scientists’ behavior, providing a focus area for future communication efforts in support of science-based decision making.

Resurrecting The Muse: Kithara And Lyric Poetry Performance Practice In Greco-Roman Antiquity, Abigail Petersen

Honors Projects

Both students and pedagogues of classical studies are familiar with the inherent musicality of Greek and Latin poetry, and they also widely accept the idea that poets sang their works to accompaniment on a kithara, or large lyre. However, little work has been done to perform works of poetry according to this tradition, and thus many modern attempts at oral recitation feature a forced and pedantic rhythm that bores the listener and fails to do justice to the revered art of Greco-Roman poetry. Through a review of primary and secondary sources, I examine the construction of the kithara, the context …

Itaconate Transporter Slc13a3 Impairs Tumor Immunity Via Endowing Ferroptosis Resistance, Heng Lin, Kole Tison, Yuheng Du, Paul Kirchhoff, Chan Kim, Weichao Wang, Hannah Yang, Michael Pitter, Jiali Yu, Peng Liao, Jiajia Zhou, Linda Vatan, Sara Grove, Shuang Wei, Thomas Vigil, Yatrik M Shah, Richard Mortensen, Ilona Kryczek, Lana Garmire, Jwala P Sivaccumar, Ashwin Kumar Ramesh, Ningyan Zhang, Zhiqiang An, Shaomeng Wang, Weiping Zou

The Brown Foundation: Institute of Molecular Medicine

Immune checkpoint blockade (ICB) triggers tumor ferroptosis. However, most patients are unresponsive to ICB. Tumors might evade ferroptosis in the tumor microenvironment (TME). Here, we discover SLC13A3 is an itaconate transporter in tumor cells and endows tumor ferroptosis resistance, diminishing tumor immunity and ICB efficacy. Mechanistically, tumor cells uptake itaconate via SLC13A3 from tumor-associated macrophages (TAMs), thereby activating the NRF2-SLC7A11 pathway and escaping from immune-mediated ferroptosis. Structural modeling and molecular docking analysis identify a functional inhibitor for SLC13A3 (SLC13A3i). Deletion of ACOD1 (an essential enzyme for itaconate synthesis) in macrophages, genetic ablation of SLC13A3 in tumors, or treatment with SLC13A3i …

Sd-Weat: Towards Robustly Measuring Bias In Input Embeddings For Artificial Intelligence Language Models, Magnus Gray

Theses and Dissertations

Artificial intelligence (AI) is rapidly transforming industries and markets, from healthcare to entertainment, revolutionizing decision-making processes. However, as AI grow more influential, they also risk amplifying existing biases, potentially leading to harmful consequences. Recent advancements in large language models (LLMs), such as GPT-4 and Llama, have heightened concerns about bias in natural language processing (NLP) tasks, driving the need for robust methods to detect and mitigate bias. Current approaches, such as the Word Embedding Association Test (WEAT) and its sentence-level extension the Sentence Encoder Association Test (SEAT) often fall short in capturing the nuances of biases in the input embeddings …

Reading Law's Great Unread: Qualitative Computational Methods, Artificial Intelligence And The New Empirical Legal Research, Simon Wallace

PhD Dissertations

How will new computational technologies change legal research and our visions of what law is? Inspired by the work of digital humanists, Bourdieu, and sociologists of literature, this dissertation explores how the methods of “distant reading” can be used to develop new classes of critical insights about law. After situating the project theoretically, this dissertation reports on a series of new computational studies about Canadian law. Chapter 1 measures Canadian statutory and regulatory law, showing that law has grown unevenly over the past decade and a half. Chapter 2 uses new artificial intelligence to transcribe and analyze Supreme Court of …

Bowen’S Disease Mimicking Lichen Simplex Chronicus In A 56-Year-Old Filipino Man: A Case Report, Cynthia Angela Karim, Elisabeth Ryan, Reynaldo Ugalde

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Bowen's disease (BD) is a chronic skin condition presenting clinically as erythematous plaques with scales on sun-exposed areas. BD is generally regarded as a squamous cell carcinoma (SCC) in situ. In contrast, lichen simplex chronicus (LSC), also known as neurodermatitis, is a chronic skin disorder characterized by extreme pruritus. In LSC, lichenified plaques form primarily on accessible body parts due to repeated scratching or rubbing.

Case Illustration: A 56-year-old male presented with a solitary chronic plaque with a central ulcer and erosions on his left upper thigh. Dermoscopy findings were glomerular vessels and a scaly surface, which are …

Algorithmic Reconstruction Of High-Fidelity Synthetic Sird Data, Dylan Mack

Electrical and Systems Engineering Undergraduate Student Research

During infectious disease outbreaks, epidemiologists are faced with problems similar to those of state estimation. Often, only population-level measures of the outbreak are available, such as infection counts per week or test positivity rates. However, these aggregate statistics yield little insight into the individual-level dynamics of an epidemic. Further, empirical data does not directly measure transmission network structure and producing this information via contact tracing is extremely resource-intensive and scales poorly. In this poster, I present an algorithm that produces synthetic, individual-level disease state measurements that both obey the mechanics of an SIRD model and, in aggregate, match empirical infection …
