Starpose: 3d Human Pose Estimation Via Spatial-Temporal Autoregressive Diffusion, Haoxin Yang, Weihong Chen, Xuemiao Xu, Cheng Xu, Peng Xiao, Cuifeng Sun, Shaoyu Huang, Shengfeng He

Research Collection School Of Computing and Information Systems

Monocular 3D human pose estimation remains a challenging task due to inherent depth ambiguities and occlusions. Compared to traditional methods based on Transformers or Convolutional Neural Networks (CNNs), recent diffusionbased approaches have shown superior performance, leveraging their probabilistic nature and high-fidelity generation capabilities. However, these methods often fail to account for the spatial and temporal correlations across predicted frames, resulting in limited temporal consistency and inferior accuracy in predicted 3D pose sequences. To address these shortcomings, this paper proposes StarPose, an autoregressive diffusion framework that effectively incorporates historical 3D pose predictions and spatialtemporal physical guidance to significantly enhance both the …

Sifar: A Simple Faster Accelerated Variance‑Reduced Gradient Method, Zhize Li

Research Collection School Of Computing and Information Systems

In this paper, we propose a simple faster accelerated gradient method called SIFAR for solving the finite-sum optimization problems. Concretely, we consider both general convex and strongly convex settings: i) For general convex finite-sum problems, SIFAR improves previous state-of-the-art result given by Varag. In particular, for large-scale problems or the convergence error is not very small, SIFAR obtains the first optimal result O(n), matching the lower bound. ii) For strongly convex finite-sum problems, we also show that SIFAR can achieve the optimal convergence rate matching the lower bound. Besides, SIFAR enjoys a simpler loopless algorithmic structure while previous algorithms use …

Affinitytune: A Prompt-Tuning Framework For Few-Shot Anomaly Detection On Graphs, Jingyan Chen, Guanghui Zhu, Guansong Pang, Chunfeng Yuan, Yihua Huang

Research Collection School Of Computing and Information Systems

Graph anomaly detection (GAD) is a critical task with applications in domains such as networking, finance, and bioinformatics. % However, the scarcity of labeled anomalies and the limitations of unsupervised methods hinder effective detection. % While semi-supervised and few-shot learning approaches offer improvements, they struggle with knowledge transfer and rely heavily on labeled data. % Recent advancements in prompt tuning on graphs provide a promising direction, but their application to heterophilous graphs in anomaly detection remains underexplored. % In this work, we propose AffinityTune, a novel framework for few-shot graph anomaly detection based on prompt tuning. % Our approach introduces …

Role Of Social Media Mindfulness In Combatting Fake News Propagation, Gaurav Bansal, Fiona Fui-Hoon Nah, Jason B. Thatcher

Research Collection School Of Computing and Information Systems

The dissemination of fake news by social media users is a key factor in the escalation of misinformation. Research suggests that social media networks are becoming increasingly homophilic, which leads to an overreliance on social media friends that contributes to the spread of fake news. However, little is known about how social media mindfulness can reduce the sharing of fake news. To investigate this research question, we conceptualized a social media mindfulness construct and developed the social media mindfulness scale. We also hypothesize that social media mindfulness lowers overreliance on friends’ knowledge, which increases skepticism about social media news that …

Gnncontext: Gnn-Based Code Context Prediction For Programming Tasks, Xiaoye Zheng, Zhiyuan Wan, Shun Liu, Kaiwen Yang, David Lo, Xiaohu Yang

Research Collection School Of Computing and Information Systems

A code context model comprises source code elements and their relations relevant to a programming task. The capture and use of code context models in software tools can benefit software development practices, such as code navigation and search. Prior research has explored approaches that leverage either the structural information of code or interaction histories of developers with integrated development environments to automate the construction of code context models. However, these approaches primarily capture shallow syntactic and lexical features of code elements, with limited ability to capture contextual and structural dependencies among neighboring code elements. In this paper, we propose GNNContext, …

Consistent Client Simulation For Motivational Interviewing-Based Counseling, Yizhe Yang, Palakorn Achananuparp, Heyan Huang, Jing Jiang, Nicholas Gabriel Lim, Cameron Shi Ern Tan, Phey Ling Kit, Jenny Xiuhui Giam, John Pinto, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Simulating human clients in mental health counseling is crucial for training and evaluating counselors (both human or simulated) in a scalable manner. Nevertheless, past research on client simulation did not focus on complex conversation tasks such as mental health counseling. In these tasks, the challenge is to ensure that the client’s actions (i.e., interactions with the counselor) are consistent with with its stipulated profiles and negative behavior settings. In this paper, we propose a novel framework that supports consistent client simulation for mental health counseling. Our framework tracks the mental state of a simulated client, controls its state transitions, and …

Mixture Effects On Metal Accumulation In The Asian Clam, Corbicula Fluminea, Mark A. Huff

Surgery Articles

INTRODUCTION: The treatment of post-traumatic elbow arthritis poses a significant challenge for orthopedic surgeons, especially in young active patients. Total elbow arthroplasty is often the recommended treatment option in older patients; however, interpositional arthroplasty remains a viable option in high-demand patients.

CASE REPORT: We report a case of a 50-year-old male who presented after the development of post-traumatic arthritis of the elbow after multiple prior surgeries. He was treated with an interpositional arthroplasty using an Achilles tendon graft and allowed immediate range of motion as tolerated in a hinged elbow brace without the use of any form of distraction external …

Perceived Leadership Behaviors And Workplace Motivation: The Predictive Role Of Generational Cohorts In The U.S. Construction Industry, Leslie D. Klinegardner

Electronic Theses and Dissertations

The purpose of this study was to examine the extent to which perceived leadership behaviors predicted workplace motivation among construction workers across generational cohorts in the Greater Houston, Texas area. Grounded in self-determination theory, the research explored how transformational, transactional, and passive-avoidant leadership behaviors predicted the satisfaction and frustration of psychological needs for autonomy, competence, and relatedness. The analysis also considered whether leadership behaviors and generational cohort served as significant predictors of workplace motivation outcomes. The study followed a quantitative, predictive, cross-sectional design using survey methodology. Data were collected using the Multifactor Leadership Questionnaire (MLQ) and the Basic Psychological Need …

Mode Regulates Alternative Nitrogenase Expression In Themethanogen Methanosarcina Acetivorans, Melissa Chanderban, Daniel J. Lessner

Biological Sciences Faculty Publications and Presentations

All methanogens that can fix nitrogen use molybdenum (Mo) nitrogenase. Some methanogens, including Methanosarcina acetivorans, also contain alternative vanadium- and iron-nitrogenases, encoded by the vnf and anf operons, respectively. These nitrogenases are produced when there is insufficient Mo to support Mo-nitrogenase activity. The factors that control the expression of the alternative nitrogenases in response to Mo availability are unknown in methanogens. Here we show that ModE is the regulator that represses transcription of the vnf and anf operons in M. acetivorans when cells are grown with Mo. CRISPRi repression of modE results in a significant increase in the transcription of …

Subjective Socioeconomic Status Moderates Self-Esteem Reactivity To Daily Stressor Exposure: Evidence From A Daily Diary Approach, Yi Jing Chua, Nadyanna M. Majeed, Verity Yu Qing Lua, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

Research on self-esteem reactivity has demonstrated that self-esteem fluctuates in response to daily stressor exposure, and the strength of this relationship varies between individuals. Drawing upon the positive link between objective socioeconomic status (SES) and self-esteem, how subjective SES influences self-esteem reactivity to daily stressor exposure was explored. Using a 7-day daily diary study, the current study (N-participants = 243, N-days = 1651) adopted a multilevel analysis to demonstrate that subjective SES attenuated the within-person association between daily stressor exposure and daily self-esteem, even after controlling for demographics and objective indicators of SES. The interactions were also consistent across social …

Would Order-By-Order Auctions Be Competitive?, Thomas Ernst, Chester Spatt, Jian Sun

Research Collection Lee Kong Chian School Of Business

We model two methods of executing segregated retail orders: brokers’ routing,whereby brokers allocate orders using the market maker’s overall performance, andorder-by-order auctions, where market makers bid on individual orders, a recent U.S.Securities and Exchange Commission proposal. Order-by-order auctions improve al-locative efficiency, but face a winner’s curse reducing retail investor welfare, partic-ularly when liquidity is limited. Additional market participants competing for retailorders fail to improve total efficiency and investor welfare when entrants possess in-formation superior to incumbent wholesalers. Our results hold when new entrants are less informed or the information structure differs. We also examine the cross-subsidization of brokers’ routing.

Clinical assessments of upper limb movement (Fugl-Meyer Upper Extremity Motor Assessment, FM-UE, Action Research Arm Test, ARAT, and Wolf Motor Function Test, WMFT) and transcranial magnetic stimulation (TMS) motor mapping of the extensor digitorum communis (EDC) muscle were performed in 23 participants (3–12 months post-stroke, 10 female, 40–88 yrs) …

Does Change In Faith Maturity Reflect Maturation? Establishing Strict Measurement Invariance For The Faith Maturity Scale Across Time, Hiroki Matsuo, Tyler Greenway, Grant B. Morgan, Sarah A. Schnitker

University Faculty Publications and Creative Works

Despite its early focus on religious development and faith maturation, the psychology of religion and spirituality field underutilizes longitudinal designs; work is needed to reduce barriers to the longitudinal study of the processes by which faith matures. As a first step, the present study examines the invariance structure of the Faith Maturity Scale across three time points to assess the reliability and structure of the scale over time. The confirmatory factor analytic method was used to examine data from 572 college students. Configural, metric, scalar, and residual/strict models were tested. Findings support the full strict residual longitudinal invariance model, providing …

More Arguments For The Weakness Of The Empirical Evidence Used To Support Spanking Bans: Rejoinder To Afifi Et Al. (2025) And Kraus De Camargo (2025), Marjorie Lindner Gunnoe, Robert E. Larzelere, Christopher J. Ferguson, Ronald B. Cox Jr.

University Faculty Publications and Creative Works

In this rejoinder we address 13 concerns elicited by our invited commentary “An update on the scientific evidence for and against the legal banning of disciplinary spanking.” In addition to defending assertions made in the initial commentary, we make several new substantive arguments. In response to dissenters’ equating of non-experimental evidence against spanking with nonexperimental evidence against smoking, we demonstrate that the two are very dissimilar. We question the purpose of spanking bans, providing stronger evidence that they do not seem to prevent child abuse. We review Canada’s association with the UN’s Convention on the Rights of the Child (CRC) …

Simmel’S Reification In The Digital Era: The Commodification Of Emotional Relationships In Rent-A-Partner Services On Social Media, Juliana Pramesti

Masyarakat: Jurnal Sosiologi

This study examines the commodification of emotional relationships in Indonesia through the rise of “rent-a-partner” services on social media platforms such as Instagram and TikTok. Existing scholarship on digital intimacy has largely focused on Western and East Asian contexts, particularly dating applications, offering limited insight into how commodified intimacy operates in non-Western settings shaped by distinct socio-cultural and moral frameworks. Addressing this gap, the study draws on Georg Simmel’s concept of reification to analyze how emotional intimacy is transformed into purchasable service packages within platform-mediated environments. Using a qualitative approach that combines netnographic observation and in-depth interviews, the study demonstrates …

This study examines khanduri blang, a traditional farming ritual practiced by the community of Lamteungoh Village in Ingin Jaya District, Aceh Besar Regency. I argue that the continuing significance of khanduri blang lies in the relationship between its spiritual meanings and the communal practices through which agricultural activities are coordinated. The research draws on interviews with two village officials and seven community members, alongside observations on farming activities in Lamteungoh Village. The findings describe a sequence of ritual and agricultural activities, including communal deliberation, seed preparation, livestock slaughter, prayers, and communal meals. Khanduri blang begins with the community’s deliberation to …

Child Abuse In Colonial America, Brian Allen

Graduate Masters Theses

Child Abuse in Colonial America is an investigation of the extent to which colonial societies were aware of child abuse and how they responded. Historians often assert that awareness of the problem did not exist in America until the mid-nineteenth century; however, the evidence uncovered suggests that cases of child abuse were recognized during the colonial period and that the societal responses differed widely. Historians of childhood document myriad social, economic, political, religious, and other cultural influences that dictate how children were treated at different times and locations, and this framework is used to interpret why the responses to child …

Political Violence, Electoral Behavior, And Their Interaction With Identity, Zeeshan Saeed

All Graduate Theses and Dissertations, Fall 2023 to Present

The research takes Pakistan as a case-study to explores how political violence shapes electoral behavior by focusing on two forms of violence: terrorist interventions by non-state actors and political repression by state institutions. Analyzing multiple elections and regional contexts, the study investigates how fear inflicting non-state violence can discourage voter participation, while state sponsored violence can drive communities by triggering anger, particularly those with strong ethnic identities leading to a higher voter turnout. Overall, this work highlights how different types of violence have varying effects on voter participation, and how these effects are conditioned.
