Hatshepsut And Akhenaten: Dualities Of Gender, Religion, And Implementation Of Queer Theory, Sadie Anderson

Theses

This paper discusses 18th Dynasty pharaohs Hatshepsut and Akhenaten and the images they portrayed during their reigns. Hatshepsut, though being female, adhered to the preconstructed image of a traditional male pharaoh while Akhenaten defied the long-established artistic canon in order to create a more androgynous pharaonic identity. Both did this to legitimize their rule, connect themselves to divinity, and interpret the duality of gender innate to Egyptian religion through their iconography. Hatshepsut’s masculine depictions cemented her as the father of the polytheistic Egyptian empire over which she reigned. Akhenaten’s more androgynous representations, on the other hand, portrayed him as both …

Fabrication And Evaluation Of Multicomponent Biomimetic Scaffolds For Bone Tissue Engineering, Mozan Osman Hassan

Dissertations

Bones have an inherent ability to remodel, but critical-size defects can hinder regeneration, leading to delayed healing or non-union fractures. Traditional bone grafts have limitations, such as donor site morbidity and immune rejection, driving the need for synthetic bone substitutes. Bone tissue engineering (BTE) addresses this by developing biomimetic scaffolds that replicate bone properties. This research aimed to fabricate composite scaffolds from strontium (Sr) and zinc (Zn) doped nano-hydroxyapatite (nHAp), collagen, and poly(lactide-co-glycolide) (PLGA). Different doping percentages of Sr/Zn (1%, 2.5%, 4%) were used to fabricate the scaffolds using supercritical CO2 (ScCO2) and electrospinning techniques. Scaffolds were then analyzed for …

Does Relationship Conflict Reduce Novel Idea Communication Through Perceived Leader Openness? Power Distance Orientation As A Moderator, Ming-Hong Tsai

Research Collection School of Social Sciences

Purpose: This paper aims to investigate why followers have low perceptions of leader openness and thus feel reluctant to communicate novel ideas by examining leader–follower relationship conflict (i.e. interpersonal incompatibility) and a follower’s power distance orientation (i.e. an acceptance of uneven power distribution in organizations) as antecedents. Design/methodology/approach: The research administrators conducted a three-wave work behavior survey in Study 1, a laboratory experiment in Study 2, and an online experiment in Study 3. Findings: The results demonstrated that leader–follower relationship conflict reduced followers’ perceptions of leader openness. However, the negative impact of relationship conflict became non-significant when followers have high …

Registered Replication Report: A Large Multilab Cross-Cultural Conceptual Replication Of Turri Et Al. (2015), Braeden Hall, Kathleen Schmidt, Jordan Wagge, Savannah C. Lewis, Sophia C. Weissgerber, Felix Kiunke, ..., Andree Hartanto

Research Collection School of Social Sciences

According to the justified true belief (JTB) account of knowledge, people can truly know something only if they have a belief that is both justified and true (i.e., knowledge is JTB). This account was challenged by Gettier, who argued that JTB does not explain knowledge attributions in certain situations, later called “Gettier-type cases,” wherein protagonists are justified in believing something to be true, but their belief was correct only because of luck. Laypeople may not attribute knowledge to protagonists with justified but only luckily true beliefs. Although some research has found evidence for these so-called Gettier intuitions, Turri et al. …

A Rose Or A Unicorn? Asean’S Mission Under The Spotlight, Lily Kong

Research Collection School of Social Sciences

In a commentary, SMU President Professor Lily Kong explores the question posed by political scientist Donald Emmerson in 1995 - is Southeast Asia more like a vibrant rose or an elusive unicorn? Against the backdrop of the 44th ASEAN Summit, with the theme "Connectivity and Resilience", Prof Kong highlights ASEAN's efforts in fostering regional connectivity and resilience through economic growth, cultural exchanges, and digital advancements. Despite substantial economic integration and digital connectivity, she points out that ASEAN faces challenges in creating a cohesive regional identity.

Deliberately Making And Correcting Errors In Mathematical Problem-Solving Practice Improves Procedural Transfer To More Complex Problems, Janson Boon Khang Yap, Sarah Shi Hui Wong

Research Collection School of Social Sciences

How can students effectively learn and transfer mathematical procedures to solve new problems? Here, we tested the effects of deliberately committing and correcting errors during mathematical problem-solving practice on transfer of the learned procedures. In two experiments, university students were instructed on mathematical algorithms (synthetic division and matrix multiplication) and solved practice problems during open-book study. Learners were then tested on flexibly adapting the algorithms to solve novel problems that were structurally more complex or embedded in “real-life” scenarios (i.e., mathematical word problems). Deliberately committing and correcting procedural errors during problem-solving practice yielded better transfer than errorless repeated practice (Experiment …

Resilient Tcp Variant Enabling Smooth Network Updates For Software-Defined Data Center Networks, Abdul Basit Dogar, Sami Ullah, Yiran Zhang, Hisham Alasmary, Muhammad Waqas, Sheng Chen

Research outputs 2022 to 2026

Network updates have become increasingly prevalent since the broad adoption of software-defined networks (SDNs) in data centers. Modern TCP designs, including cutting-edge TCP variants DCTCP, CUBIC, and BBR, however, are not resilient to network updates that provoke flow rerouting. In this paper, we first demonstrate that popular TCP implementations perform inadequately in the presence of frequent and inconsistent network updates, because inconsistent and frequent network updates result in out-of-order packets and packet drops induced via transitory congestion and lead to serious performance deterioration. We look into the causes and propose a network update-friendly TCP (NUFTCP), which is an extension of …

To meet the needs of the patient population, the responsibility of providing clinical genetic services falls on general and specialty physicians. However, their education regarding these essential services is not standardized in medical school curricula nor has it ever been evaluated. The purpose of this work is to describe the self-perceived knowledge, clinical comfort, and perspectives of Pakistani medical students toward their medical genetics' education. A web-based survey was distributed electronically to medical schools around the country. The survey comprised …

Clinical Outcome-Guided Deep Temporal Clustering For Disease Progression Subtyping, Yejin Kim

Faculty, Staff and Student Publications

Objective: Complex diseases exhibit heterogeneous progression patterns, necessitating effective capture and clustering of longitudinal changes to identify disease subtypes for personalized treatments. However, existing studies often fail to design clustering-specific representations or neglect clinical outcomes, thereby limiting the interpretability and clinical utility.

Method: We design a unified framework for subtyping longitudinal progressive diseases. We focus on effectively integrating all data from disease progressions and improving patient representation for downstream clustering. Specifically, we propose a clinical Outcome-Guided Deep Temporal Clustering (OG-DTC) that generates representations informed by clustering and clinical outcomes. A GRU-based seq2seq architecture captures the temporal dynamics, and the model …

Biomedical Engineering Faculty Research and Publications

The understanding of foot and ankle biomechanics is improving as new technology provides more detailed information about the motion of foot and ankle bones with biplane fluoroscopy, as well as the ability to analyze the hindfoot under weightbearing conditions with weightbearing computed tomography. Three-dimensional anatomical coordinate systems are necessary to describe the 3D alignment and kinematics of the foot and ankle. The lack of standard coordinate systems across research study sites can significantly alter experimental data analyses used for pre-surgical evaluation and post-operative outcome assessments. Clinical treatment paradigms are changing based on the expanding knowledge of complex pes planovalgus morphologies …

Morphology Of The Normative Human Cone Photoreceptor Mosaic And A Publicly Available Adaptive Optics Montage Repository, Robert F. Cooper, Snega Kalaparambath, Geoffrey K. Aguirre, Jessica I. W. Morgan

Biomedical Engineering Faculty Research and Publications

Adaptive optics ophthalmoscopy has enabled visualization of the in vivo human photoreceptor mosaic in health, disease and its treatment. Despite this, the clinical utility of the imaging technology has been limited by a lack of automated analysis techniques capable of accurately quantifying photoreceptor structure and a lack of an available normative image database. Here, we present a fully automated algorithm for estimating cone spacing and density over a complete adaptive optics montage along with a database of normative images and cone densities. We imaged the cone mosaics surrounding the fovea and along the horizontal and vertical meridians of fifty normal-sighted …

Biomedical Engineering Faculty Research and Publications

Purpose

Understanding how spinal orientation affects injury outcome is essential to understand lumbar injury biomechanics associated with high-rate vertical loading.

Methods

Whole-column human lumbar spines (T12–L5) were dynamically loaded using a drop tower to simulate peak axial forces associated with high-speed aircraft ejections and helicopter crashes. Spines were allowed to maintain natural lordotic curvature for loading, resulting in a range of orientations. Pre-test X-rays were used to quantify specimen orientation at the time of loading. Primary fracture types were identified (wedge, n = 6; burst, n = 4; hyperextension, n = 4) and compared for loading parameters and lumbar orientation. …

Realtime And Noninvasive Assessment Of Endotracheal Tube Displacement Using Near-Infrared And Visible Cameras, Tongtong Lu, Pawjai Khampang, Ahmed Beydoun, Rebecca Rodhe, Wenzhou Hong, Joseph E. Kerschner, Bing Yu

Biomedical Engineering Faculty Research and Publications

Endotracheal tube (ETT) intubation is a medical procedure routinely used for achieving mechanical ventilation in critically ill patients. Appropriate ETT placement is crucial as undetected tube migration may cause multiple complications or even fatalities. Therefore, prompt detection of unplanned movement of the ETT and immediate action to restore proper placement are essential to ensure patient safety. Despite this necessity, there is not a widely adopted tool for real-time assessment of ETT displacement. We have developed a device, a dual-camera endotracheal tube or DC-ETT, to address this unmet clinical need. This device uses a near-infrared (NIR) LED and a side-firing optical …

Linkage Between Fuz And Gpr161 Genes Regulates Sonic Hedgehog Signaling During Mouse Neural Tube Development, Richard H Finnell

Faculty, Staff and Students Publications

Sonic hedgehog (Shh) signaling regulates embryonic morphogenesis utilizing the primary cilium, the cell's antenna, which acts as a signaling hub. Fuz, an effector of planar cell polarity signaling, regulates Shh signaling by facilitating cilia formation, and the G protein-coupled receptor 161 (Gpr161) is a negative regulator of Shh signaling. The range of phenotypic malformations observed in mice bearing mutations in either of the genes encoding these proteins is similar; however, their functional relationship has not been previously explored. This study identified the genetic and biochemical linkage between Fuz and Gpr161 in mouse neural tube development. Fuz was found to be …

Concrete Design: Underwater Concrete Forms In A Saltwater Environment, Noah Z. Lau

Construction Management

This following project investigated the effects of salt on the concrete curing process. Concrete possesses numerous strengths, making it extremely versatile. This makes it one of the most utilized construction materials. New improved methods are constantly being developed for concrete’s application as a construction material. While concrete is a flexible material with many strengths, it is not without its flaws. Concrete, while strong in compression is weak in tension. It has long cure times and doesn’t generally handle moisture well. This paper evaluates concrete’s change in strength from letting concrete cure in a salt-based underwater environment. To determine the full …

Anomalies, Option Volume, And Disagreement, Allaudeen Hameed, Byoung-Hyun Jeon

Finance Faculty Research and Publications

We document robust amplification of stock market anomaly returns associated with elevated option trading volume driven by disagreement trades. Consistent with the correction of mispricing associated with biased beliefs, anomaly returns are higher when disagreement option volume is high prior to earnings announcements. Additionally, we demonstrate that disagreement-based option volume is negatively related to future stock returns among stocks that are overpriced based on anomaly characteristics. Our findings also concentrate in stocks that are also difficult to short, emphasizing the combined impact of investor bias and shorting costs. Leveraging the staggered adoption of extensible Business Reporting Language, we establish a …

Head and neck metastasis of colorectal adenocarcinoma is exceedingly rare with most cases presenting in the liver, lungs, or peritoneum. This report describes the case of a 53-year-old female patient with a past medical history significant for mucinous adenocarcinoma of the colon treated with a right hemicolectomy. She was thought to be in remission but presented a few years later with a new, isolated left cervical neck mass and symptoms of left eye ptosis and dryness. Diagnostic imaging and biopsy confirmed the neck mass to be a metastatic lesion from her prior mucinous adenocarcinoma, with immunohistochemical findings specific for colorectal …

Constitutional Disorder, Robert L. Tsai

Faculty Scholarship

This is a review essay inspired by two books: Yuval Levin's American Covenant (2024) and Erwin Chemerinsky's No Democracy Lasts Forever (2024). I make the following points. First, all treatments of the U.S. Constitution can be mapped on a continuum from the worshipful to the diagnostic. Second, Levin's account, which inclines toward the devotional, extols certain features deemed both originalist and virtuous: social unity over untidiness, consensus over dissent, fear and loathing of mass politics. Third, such accounts may not be sufficiently nimble to grapple with contemporary problems such as new forms of oligarchy or movement capture of traditional parties. …

Contracting Hoop Dreams: Using Sports Law To Teach Transactional Practice, Cody Jacobs

Faculty Scholarship

One of the places I find the most joy in teaching legal writing is problem development—writing compelling factual scenarios that give students interesting legal issues to work through is rewarding and fun.  The best prompts will motivate students to really jump into their role representing their client and encourage them to think about the “big picture”—how the law ties into social, political, and economic structures in society at large.  Much has been written about the best ways to do this in the context of litigation assignments (briefs, memos, etc.), but there has been less discussion about problem creation in the …

Transcription And Post-Translational Mechanisms: Dual Regulation Of Adiponectin-Mediated Occludin Expression In Diabetes, Yanru Duan, Demin Liu, Huahui Yu, Shihan Zhang, Yihua Xia, Zhiyong Du, Yanwen Qin, Yajing Wang, Xin-Liang Ma, Huirong Liu, Yunhui Du

Department of Emergency Medicine Faculty Papers

BACKGROUND: Occludin, a crucial component of tight junctions, has emerged as a promising biomarker for the diagnosis of acute ischemic disease, highlighting its significant potential in clinical applications. In the diabetes, Occludin serves as a downstream target gene intricately regulated by the adiponectin (APN) signaling pathway. However, the specific mechanism by which adiponectin regulates Occludin expression remains unclear.

METHODS AND RESULTS: Endothelial-specific Ocln knockdown reduced APN-mediated blood flow recovery after femoral artery ligation and nullified APN's protection against high-fat diet (HFD)-triggered apoptosis and angiogenesis inhibition in vivo. Mechanically, we have meticulously elucidated APN's regulatory role in Occludin expression through a …

How Biblical Theology Supports Jesus’S Teaching On Food Cleanliness, Mitch Mcgeath

Biblical Studies Student Projects

This paper uses a framework of biblical theology to gain a deeper understanding of Jesus's teaching on food cleanliness in Mark 7:14-23. Using the framework of levitical law, including God's original intent for the law as a compass pointing towards moral purity, Jesus redefines the law in himself, thus fulfilling it in full and abrogating it in part.
