Time Scales And Mechanisms Of Uranium Uptake In Altered Ocean Crust; Observations From The ∼15 Million Year-Old Site 1256 In The Eastern Equatorial Pacific, Morten B. Andersen, Joel B. Rodney, Heye Freymuth, Flurin Vils, Michelle Harris, Kari Cooper, Damon A.H. Teagle, Tim Elliott

School of Geography, Earth and Environmental Sciences

The alteration of ocean crust through hydrothermal seawater circulation facilitates chemical exchange between Earth's surface and interior. Hydrothermal alteration leads to uranium (U) removal from seawater and net U uptake by the ocean crust, particularly during low temperature alteration that occurs on the vast ocean ridge flanks away from the spreading axes. Determining the timescales of U uptake and its associated ²³⁸U/²³⁵U signature has important implications for understanding U exchange processes during subduction and recycling into the mantle. Here we study the U systematics of ∼15 million year-old ocean crust drilled at Site 1256 on the eastern …

Mixed Methods Study Protocol: Language Identity, Discrimination, And Mental Health Among Multilingual 1.5 Generation Asian/Asian American Immigrant Young Adults, Chulwoo Park, Mark Edberg, Janet Yougi Bang, Avizia Yim Long

Faculty Research, Scholarly, and Creative Activity

Language identity, an understudied factor, can influence isolation and discrimination, leading to disparities in well-being and mental health among immigrants. This study aims to investigate the role of language identity on structural racism and discrimination among 1.5 generation Asian/Asian American immigrants in a diverse U.S. state. We developed a three-step sequential approach: Stage 1—qualitative analysis (1A, focus group discussion; 1B, in-depth interviews); Stage 2—quantitative analysis (2A, language identity measurement scale; 2B, cross-sectional online survey; 2C, multivariate multiple linear regression); Stage 3—another round of qualitative analysis (3A, follow-up in-depth chronological interviews). Therefore, this study will contribute to the field by introducing …

Towards An Extended Resource Theory Of Marital Power: Parental Education And Household Decision-Making In Rural China, Cheng Cheng, Yu Xie

Research Collection School of Social Sciences

Existing literature on the resource theory of marital power has focused on the relative resources of spouses and overlooked the resource contributions of spouses’ extended families. We propose an extended resource theory that considers how the comparative resources of a couple’s natal families are directly associated with marital power, net of the comparative resources of the couple. Using data from the China Panel Family Studies, we examine how the relative education of a couple’s respective parents affects the wife’s decision-making power, net of the relative education of the couple. Results suggest that the higher the wife’s parental education relative to …

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 …

What Is Beyond Measurement For Social Cohesion?, Qian Hui Tricia Tok, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

“What gets measured gets managed” has long been a mantra to rally improvement throughout various domains of life. Perhaps this is also the case for existing work on social cohesion, whereby much of its conceptual and operational elements have received interest in both academic and policy research aiming for practical improvement with regard to the cohesiveness of communities and societies. We contend, however, that not everything that matters for social cohesion may be measurable, and not everything that has been measured for social cohesion may matter. This is not to suggest that not measuring any indicators is better than measuring …

Enhancing Recipe Retrieval With Foundation Models: A Data Augmentation Perspective, Fangzhou Song, Bin Zhu, Yanbin Hao, Shuo Wang

Research Collection School Of Computing and Information Systems

Learning recipe and food image representation in common embedding space is non-trivial but crucial for cross-modal recipe retrieval. In this paper, we propose a new perspective for this problem by utilizing foundation models for data augmentation. Leveraging on the remarkable capabilities of foundation models (i.e., Llama2 and SAM), we propose to augment recipe and food image by extracting alignable information related to the counterpart. Specifically, Llama2 is employed to generate a textual description from the recipe, aiming to capture the visual cues of a food image, and SAM is used to produce image segments that correspond to key ingredients in …

Beat-It : Beat-Synchronized Multi-Condition 3d Dance Generation, Zikai Huang, Xuemiao Xu, Cheng Xu, Huaidong Zhang, Chenxi Zheng, Jing Qin, Shengfeng He

Research Collection School Of Computing and Information Systems

Dance, as an art form, fundamentally hinges on the precise synchronization with musical beats. However, achieving aesthetically pleasing dance sequences from music is challenging, with existing methods often falling short in controllability and beat alignment. To address these shortcomings, this paper introduces Beat-It, a novel framework for beat-specific, key pose-guided dance generation. Unlike prior approaches, Beat-It uniquely integrates explicit beat awareness and key pose guidance, effectively resolving two main issues: the misalignment of generated dance motions with musical beats, and the inability to map key poses to specific beats, critical for practical choreography. Our approach disentangles beat conditions from music …

D2sr: Decentralized Detection, De-Synchronization, And Recovery Of Lidar Interference, Darshana Rathnayake, Hemanth Sabbella, Meera Radhakrishnan, Archan Misra

Research Collection School Of Computing and Information Systems

We address the challenge of multi-LiDAR interference, an issue of growing importance as LiDAR sensors are embedded in a growing set of pervasive devices. We introduce a novel approach named D2SR, enabling decentralized interference detection, mitigation, and recovery without explicit coordination among nearby LiDAR devices. D2SR comprises three stages: (a) Detection, which identifies interfered frames, (b) Mitigation, which performs time-shifting of a LiDAR’s active period to reduce interference, and (c) Recovery, which corrects or reconstructs the depth values in interfered regions of a depth frame. Key contributions include a lightweight interference detection algorithm achieving an F1-score of 92%, a simple …

Nigerian Software Engineer Or American Data Scientist? Github Profile Recruitment Bias In Large Language Models, Takashi Nakano, Kazumasa Shimari, Raula Gaikovina Kula, Christoph Treude, Marc Cheong, Kenichi Matsumoto

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) have taken the world by storm, demonstrating their ability not only to automate tedious tasks, but also to show some degree of proficiency in completing software engineering tasks. A key concern with LLMs is their “black-box” nature, which obscures their internal workings and could lead to societal biases in their outputs. In the software engineering context, in this early results paper, we empirically explore how well LLMs can automate recruitment tasks for a geographically diverse software team. We use OpenAI's ChatGPT to conduct an initial set of experiments using GitHub User Profiles from four regions to …

Cranioencephalic Functional Lymphoid Units In Glioblastoma, Celia Dobersalske, Jonathan Kipnis, Et Al.

2020-Current year OA Pubs

The ecosystem of brain tumors is considered immunosuppressed, but our current knowledge may be incomplete. Here we analyzed clinical cell and tissue specimens derived from patients presenting with glioblastoma or nonmalignant intracranial disease to report that the cranial bone (CB) marrow, in juxtaposition to treatment-naive glioblastoma tumors, harbors active lymphoid populations at the time of initial diagnosis. Clinical and anatomical imaging, single-cell molecular and immune cell profiling and quantification of tumor reactivity identified CD8

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. …

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 …

"Asian" Principles For The Recognition And Enforcement Of Foreign Judgments? Singapore As A Case Study, Adeline Chong

Research Collection Yong Pung How School Of Law

This paper considers if there can be said to be an “Asian” body of principles for the recognition and enforcement of foreign judgments. Tapping on the results of a research project which was conducted from 2016 to 2020, it is submitted that the answer to this query is in the negative. However, it is suggested that what marks out the “Asian” approach to private international law is the willingness of Asian countries to look outwards for reform and development and to balance the adoption of international norms against important local norms and objectives. Singapore’s approach to the recognition and enforcement …

Can Federated Learning Solve Ai’S Data Privacy Problem?: A Legal Analysis, Warren B. Chik, Florian Gamper

Research Collection Yong Pung How School Of Law

Federated learning (FL) is a method of training AI systems on different datasets without sharing data. The promise of FL is to enable AI systems to be trained on data, including personal data, while preserving data privacy and confidentiality, and thus, inter alia, facilitate compliance with data protection legislation. FL has generated a considerable interest amongst the computer science community, yet there is a dearth of legal analysis of FL. This is a problem because the question of whether FL facilitates compliance with data protection legislation is a legal question. This article will fill this lacuna by providing a comprehensive …

Mannosylated Pamam G2 Dendrimers Mediated Rate Programmed Delivery Of Efavirenz Target Hiv Viral Latency At Reservoirs, Rohini Kharwad, Mohsin Kazi, Nilesh Mahajan, Payal Badole, Sachin More, Asaad Kayali, Md Noushad Javed, Mohammed Kaleem

Mechanical Engineering Faculty Publications

In this current research, we conceptualized a novel nanotechnology-enabled synthesis approach of targeting HIV-harboring tissues via second-generation (G2) polyamidoamine (PAMAM) mannosylated (MPG2) dendrimers for programmed delivery of anti-HIV drugs efavirenz (EFV) and ritonavir (RTV). Briefly, here mannose served purpose of ligand in this EFV and RTV-loaded PAMAM G2 dendrimers, synthesized by divergent techniques, denoted as MPG2ER. The developed nanocarriers were characterized by different analytical tools FTIR, NMR, zeta potential, particle size, and surface morphology. The results of confocal microscopy showed substantial alterations in the morphology of H9 cells, favored by relatively higher drug uptake through the MPG2ER. Interestingly, the drug …

Effects Of Simultaneous Alarms On Resolution Heuristics, Amanda C. Allen

Psychology Theses & Dissertations

Automated signaling systems are frequently used to direct operator attention to potential hazards. Although these automated systems can lead to enhanced human performance, factors such as degraded alarm signal reliability and lack of trust can undermine the potential benefits of automation (Breznitz, 1984; Rice, 2009, Wickens & 2007). Additionally, work by Gilson, Mouloua, Graft, and McDonald (2001), as well as Keller and Rice (2009), suggest that an alarm contained within a larger array of alarms should not be evaluated individually. Due to the increasing use of multiple alarms in complex environments such as operating rooms and cockpits (Konkani, Oakley, & …

The False Choice Between Digital Regulation And Innovation, Anu Bradford

Faculty Scholarship

This Article challenges the common view that more stringent regulation of the digital economy inevitably compromises innovation and undermines technological progress. This view, vigorously advocated by the tech industry, has shaped the public discourse in the United States, where the country’s thriving tech economy is often associated with a staunch commitment to free markets. U.S. lawmakers have also traditionally embraced this perspective, which explains their hesitancy to regulate the tech industry to date. The European Union has chosen another path, regulating the digital economy with stringent data privacy, antitrust, content moderation, and other digital regulations designed to shape the evolution …

Commercial Boilerplate: A Review And Research Agenda, Robert E. Scott, Stephen J. Choi, Mitu Gulati

Faculty Scholarship

Boilerplate contracts have long fascinated legal scholars. But the focus has been largely on consumer contracts, with the debate centered on the question of whether take-it-or-leave-it mass-produced forms imposed on consumers by large corporations should be treated as contracts or as a problem in regulation. By contrast, commercial boilerplate — the standard forms used in transactions for corporate or sovereign bonds or merger agreements — has traditionally received little attention. The assumption has been that form contracts among sophisticated parties may differ in form but not in substance from bespoke contracts between business entities. Yet a growing body of scholarship …

The State Statutes Project, Neel Guha, Diego A. Zambrano

Faculty Scholarship

State statutes are having a moment in national debates. Partly fueled by polarization, state legislatures have pushed the boundaries on almost every important national question, from abortion and regulation of social media, all the way to police lawsuits and drug use. Take, for instance, the by now well-known example of Texas Senate Bill 8. To avoid Roe v. Wade, the Texas Legislature enacted a statute that allowed private parties (really, anyone) to sue abortion providers. The kicker was that the statute prohibited government enforcement in order to prevent Ex parte Young style challenges in federal court. Or take Montana’s attempt …

Institutional Pressures On School Leadership And Innovation After Pandemic-Related School Closures: A Phenomenological Study, Gary Eugene Skeen

Educational Leadership & Workforce Development Theses & Dissertations

The COVID-19 pandemic was a phenomenon that caused immediate change to global institutions, including education. As schools created new systems during the pandemic, as restrictions began to be eased, many divisions felt pressure to continue virtual options after schools fully reopened to students. This pressure influenced the decisions made by school leaders, with internal and external pressures dictating how leaders navigated the decisions made regarding virtual learning after pandemic-related school closures. In the presence of the widespread phenomenon of the pandemic, school leaders faced pressures to reimagine learning through innovation or revert to institutional structures normalized prior to pandemic closures. …

Investigating The Effects Of Empathy On Implicit Race Bias, Macy Kisiel

Psychology Theses & Dissertations

Over the years there have been changes to social norms, which now discourage expressions of prejudice, and changes in many people’s self-reported attitudes, but prejudice is still a major issue in present-day American society. One important step toward addressing prejudice and social injustices is to understand the psychological processes that underlie and strengthen them. The current study aimed to use an empathy passage to positively prime the schema about a minority person of color and manipulate regulation of implicit bias. The study utilized a mixed 2 × 2 design. Sixty-four participants (Mage = 20.88 years, SD = 4.75 years) were …

The Phenomenology Of Experiencing Critical Thinking In Vocational Higher Education, Sean Castleberry

Educational Leadership & Workforce Development Theses & Dissertations

This study investigated the role of critical thinking in vocational education within the Virginia Community College System by examining the lived experience of administrators, faculty, and students who are associated with vocational education. To complete this task, the researcher employed a phenomenological methodology primarily based on the philosophy of Martin Heidegger and other phenomenological philosophers including Edmund Husserl, Mark D. Vagle, and Karin Dahlberg. The goal of the research was to serve as a beginning and help close the gap in knowledge concerning how critical thinking is defined in vocational education, why it is seen as an important part of …

A Systems Theory-Based Framework For Uncertainty In Complex System Governance, Teresa Anne Crater

Engineering Management & Systems Engineering Theses & Dissertations

Complex systems are all around. A complex system is a system whose collective behavior is more than the behavior exhibited by the individual parts. Such a system is characterized by an exponential increase in information, complexity, ambiguity, emergence, and high levels of uncertainty (Jaradat, 2015). Uncertainty is intrinsic to complex systems. Uncertainty refers to epistemic situations involving imperfect or unknown information. Uncertainty can refer to the chance of certain anticipated outcomes occurring, or it can refer to the unknown events that are not foreseeable as to when or if one might occur. It applies to predictions of future events, to …

Legitimacy At Sea: Expanding Considerations Of Sea Control, Ian Birdwell

Graduate Program in International Studies Theses & Dissertations

Sea control has been marketed and accepted as a norm within the global commons, with a variety of states arguing for their visions of control to be viewed as legitimate. As a piece of the global commons, sea lanes are a critical enabler for the global economy and possess significant military and political significance, yet the literature revolving around ideas of sea control treats it as a military achievement at the end of a campaign and remains focused on naval power as the key mechanism for state involvement. What best explains the mechanism states use to achieve sea control, especially …

"Every Direction We Turn, It’S A Wall”: North Carolina School Counselors And Their Advocacy And Support For Undocumented Students’ Access To Higher Education, Wendy Eberhart Cook

Educational Leadership & Workforce Development Theses & Dissertations

High school counselors in North Carolina assist with post-secondary planning for all their students, including the approximately 3,000 undocumented students who graduate from North Carolina schools each year (Zong & Batalova, 2019). Access to post-secondary education is difficult to attain for undocumented students (Groce & Johnson, 2021), especially true for undocumented students in North Carolina, a state considered hostile to this student population due to tuition and financial aid policy (Mansfield & Hernandez, 2024). Undocumented students also face a fear of deportation, food insecurity, lower socioeconomic conditions, and language barriers (Abrego, 2006).

Despite the many barriers undocumented students face, school …

This dissertation investigates the social media strategies employed by the Taliban and ISIS. These social media strategies are used to further their strategic objectives in propaganda, recruitment, and operational coordination. Through a comprehensive analysis, the study explores how these extremist groups adapt their digital tactics in response to evolving military and political landscapes. Utilizing case studies from key military engagements and applying theoretical frameworks of rational actor theory, social identity theory, and finite and …

Simulating The Compound Impacts Of Climate Change And Sea-Level Rise On Coastal Shallow Groundwater Using An Integrated Surface-Subsurface Hydrologic Model, Zhaoyi Cai

Civil & Environmental Engineering Theses & Dissertations

As climate change intensifies and sea levels rise, coastal aquifers become increasingly vulnerable to interacting oceanic and terrestrial processes. This dissertation examines the combined impacts of climate change and sea-level rise (SLR) on coastal shallow groundwater using an integrated surface-subsurface hydrologic model, focusing on the low-lying Little Creek watershed (LCW) in Norfolk, Virginia. The SWAT-MODFLOW model, a coupled system, unifies land surface, streamflow, and groundwater processes, providing a comprehensive framework for watershed-aquifer analysis. Model parameters were derived from U.S. Geological Survey datasets, relevant literature, station records, and technical reports, followed by meticulous calibration. The validated model first simulated baseline groundwater …

Short-Semester Courses: Mitigating Unfavorable Precollege Issues For Students At A Technical College, James T. Moore Jr.

Educational Leadership & Workforce Development Theses & Dissertations

Technical colleges serve a distinct student population and provide an open access point to higher education for students not wishing to attend a university. Graduation and retention rates continue to demonstrate a gap between what technical colleges wish to achieve and the actual achievement. Technical college leaders continue to embrace policies and programs intended to support students at university system schools and which poorly serve the needs of technical college students. As a result, little is known about the lived experiences of technical college students. Data were collected through a six individual semi-structured interview. The six participants of the study …
