Professional Learning Communities In Virtual K-12 Schools: Survey Evidence From Texas, Charles L. Tracy Jr

Electronic Theses and Dissertations

Professional Learning Communities (PLCs) have been viewed as a tool for improving teacher practices and student outcomes in schools for more than thirty years. Much of the existing research on their effectiveness has focused on the traditional school setting. With the explosion of virtual K-12 schools, less is known about how PLCs function in the fully online environment and how teachers perceive their overall effectiveness. The purpose of this study was to explore the perceptions of teachers working in a full-time virtual school with regard to their participation in Professional Learning Communities. A review of the literature examined the importance …

The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

Following Crémer and McLean (1985, 1988) for finite type spaces and McAfee and Reny (1992) for continuous ones, we establish two respective sufficient conditions for the existence of efficient, ex ante budget-balanced mechanisms satisfying Bayesian incentive compatibility (BIC) and interim individual rationality (IIR) in bilateral trade settings with interdependent values and correlated beliefs. We then utilize the ex ante welfare (EAW) condition proposed by Kunimoto and Zhang (2026), which is necessary for the stricter requirement of ex post budget balance. We prove that while the EAW condition is sufficient in a two-type model and generalizes existing conditions in the literature, …

Dynamics Of High-Growth Young Firms And The Role Of Venture Capitalists, Yoshiki Ando

Research Collection School Of Economics

Motivated by the substantial growth and upfront investments of venture capital (VC)-backed firms observed in administrative US Census data, this study develops a life-cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation. The calibrated model explains the life-cycle dynamics of firms with different sources of financing and suggests that venture capitalists' managerial advice accounts for around 22% of the growth in VC-backed firms. A counterfactual economy without VC financing would experience an aggregate consumption loss of around 0.46%.

The Treatment Of Digital Assets In Insolvency, Nydia Remolina Leon, Aurelio Gurrea-Martinez, Daniel Liu

Research Collection Yong Pung How School Of Law

This article provides a comprehensive analysis of the treatment of digital assets in insolvency. Given that cryptoassets can be the subject of various transactions—including purchase, sale, custody, and lending—understanding their nature and implications in insolvency is relevant for any firm, not just cryptoexchanges. The article begins by offering a general overview of the world of cryptoassets. It then examines the nature of cryptoassets from accounting, financial, and legal perspectives. While much of the literature on insolvency and cryptoassets has primarily focused on the analysis of whether cryptocurrencies constitute property of the estate, this article explores additional issues, such as the …

From Open Banking To Banking-As-A-Service: Regulatory Challenges In The Evolution Of Financial Intermediation, Nydia Remolina Leon

Research Collection Yong Pung How School Of Law

Over the past decade, financial innovation has moved from open banking, centred on consumer-permissioned data sharing, to banking-as-a-service (BaaS), which modularises core banking functions through application programming interfaces. This shift allows fintechs and non-financial platforms to embed financial products seamlessly, reducing transaction costs and fostering innovation. Yet the 2024 collapse of Synapse in the United States exposed the fragility of this model when intermediaries operate outside robust oversight, leaving consumers without recourse and revealing liability fragmentation and regulatory blind spots. This paper distinguishes BaaS from open banking, open finance, and embedded finance, and maps leading global models – from bank-led …

Parameterized Approximation Schemes For Fair Clustering In Doubling Metrics, Xiaoliang Wu, Ting Liang, Zhize Li, Qilong Feng

Research Collection School Of Computing and Information Systems

Fair clustering has garnered considerable attention, with various fairness notions proposed to ensure equitable representation across demographic groups. In this paper, we focus on the k-center problem in bounded doubling metrics under two popular fairness requirements: group fairness and data summarization fairness, referred to Group Fair k-Center (Gf-k-Cen) and Data Summarization Fair k-Center (Dsf-k-Cen), respectively. Both fairness notions extend classical clustering formulation by associating each data point with a demographic label. Motivated by recent advances in parameterized approximation results for fair clustering, we investigate whether these problems admit Fixed-Parameter Tractable (FPT) approximation schemes in bounded doubling metrics. The previous algorithms …

A Deep Reinforcement Learning Framework For Dynamic Order And Rack Scheduling In Robotic Mobile Fulfillment Systems, Lingjun Wang, Bayi Cheng, Zhiguang Cao, Aldy Gunawan

Research Collection School Of Computing and Information Systems

Robotic mobile fulfillment systems play a vital role in modern e-commerce, but their efficiencydepends on overcoming a critical challenge: coordinating orders and racks effectively under dynamicorder arrivals, diverse delivery deadlines, and resource sharing among multiple stations. This papertackles the resulting dynamic order and rack scheduling problem and proposes an intelligentscheduling framework centred on deep reinforcement learning. At its core is TriNet-PPO, whichtrains a scheduling policy using TriNet, a tripartite graph neural network encoder tailored to capturethe many-to-many relationships among orders, racks, and items. Furthermore, we introduce IPCSA,an integer programming-based cooperative scheduling algorithm that maps station-level actionpreferences to conflict-free joint decisions …

The purpose of this qualitative case study was to explore how college students described their use of these tools in academic courses and to identify the benefits and challenges associated with integrating them into learning experiences. Data were collected through semistructured interviews with undergraduate students …

The Rending Of The Temple Curtain In The Gospel Of Luke: Its Relocation And Implications, Kim Kai Chan

Electronic Theses and Dissertations

The rending of the temple curtain at Jesus’s death is recorded in all three Synoptic Gospels, yet Luke relocates the event from after to before Jesus’s death, creating interpretive challenges. While Mark connects the curtain’s tearing to the rending of the heavens at Jesus’s baptism through the verb σχίζω, this study argues that Luke reframes the tearing motif by linking the curtain’s rending to the tearing of the new garment in the parables of Luke 5:36–39, likewise employing σχίζω.

On the one hand, these parables in Luke 5 represent Jesus’s reasoning with his critics that to resist him and his …

Cultural Intelligence And Leadership: Examining School Principals’ Impact On Teacher Belonging, Retention, And Conflict Resolution, Quincy C. Commerford

Electronic Theses and Dissertations

The increasing diversity throughout the United States, especially reflected in the school system, has increased the need for school leaders who can effectively lead culturally diverse communities, and, specifically, for culturally diverse teachers. Cultural intelligence has gradually become a leadership competency alongside other intelligences, such as emotional and social, but little is known about how a school leader’s cultural intelligence affects culturally diverse teachers sense of belonging, their experiences with conflict, and overall teacher retention. In this study the researcher examined how a school leader’s cultural intelligence affects teachers’ sense of belonging in two culturally diverse secondary school settings. Using …

Aquaculture is increasingly important for food, nutrition and livelihoods in Kenya, but the sector still faces persistent constraints in extension delivery, farmer learning, input access, market coordination and information reliability. This review examines how social media and related digital communication tools are shaping aquaculture development in Kenya, with attention to impacts, challenges, governance needs and strategic directions. A systematic literature review of studies and institutional sources published between 2015 and 2025 was conducted. The search identified 388 records, of which 45 sources were included in the final synthesis after screening, eligibility assessment and quality appraisal. Because the evidence was heterogeneous, …

Efficient Test-Time Retrieval Augmented Generation, Hailong Yin, Bin Zhu, Jingjing Chen, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Although Large Language Models (LLMs) demonstrate significant capabilities, their reliance on parametric knowledge often leads to inaccuracies. Retrieval Augmented Generation (RAG) mitigates this by incorporating external knowledge, but these methods may introduce irrelevant retrieved documents, leading to inaccurate responses. While the integration methods filter out incorrect answers from multiple responses, but lack external knowledge like RAG methods, and their high costs require balancing overhead with performance gains. To address these issues, we propose an Efficient Test-Time Retrieval-Augmented Generation Framework named ET2RAG to improve the performance of LLMs while maintaining efficiency. Specifically, ET2RAG is a training-free method, that first retrieves the …

Dynamic Spectral Denoising With Global-Context Attention For Multi-Behavior Recommendation, Miaomiao Cai, Yunshan Ma, Fangqi Zhu, Junfeng Fang, Zhijie Zhang, Zhiyong Cheng, Xiang Wang, See-Kiong Ng

Research Collection School Of Computing and Information Systems

Multi-behavior recommendation improves target-behavior predic-tion by exploiting heterogeneous auxiliary feedback (e.g., view,collect, and cart), yet its robustness is often undermined by behavior-dependent noise and inconsistency. We argue that the key bottle-neck is not merely noisy behaviors, but a representation-level failurecaused by two coupled heterogeneities. First, intra-behavior rep-resentation entanglement arises when multi-hop propagationblends incidental signals with true preferences in the embeddingspace. This entanglement renders coarse spatial denoising inef-fective, since it cannot suppress noise without sacrificing weak-but-informative niche signals. Second, inter-behavior reliabilityheterogeneity complicates cross-behavior fusion, as the predic-tive value of auxiliary behaviors varies substantially across usersand contexts. Without reliability calibration, aggregation can …

Semiparametric Cointegrating Rank Selection For Curved Cross-Section Time Series, Peter C. B. Phillips

Research Collection School Of Economics

Cointegrating rank selection is studied in a function space reduced rank regression where the data are time series of cross-section curves. Consistent cointegrating rank estimation is developed using information criteria extended to curve time series environments. The asymptotic theory involves two-parameter Gaussian processes that generalise the standard limit processes involved in cointegrating regressions. Simulations provide evidence of the effectiveness of consistent rank selection by the BIC criterion and the tendency of AIC to overestimate order as in standard lag order selection in autoregression, as well as in reduced rank regression with multiple time series.

Connectivity And Selective Rural Migration, Lin Ma, Yuan Mei, Qunfeng Wu, Mingzhi Xu

Research Collection School Of Economics

How does infrastructure shape rural development? Using household panel data from a nationally representative sample of Chinese villages, matched to high-resolution highway maps, we find that road expansion between 2000 and 2015 operates mainly through reallocation, with less productive farmers scaling down or exiting and more productive farmers remaining and expanding. We quantify the aggregate and distributional consequences in a dynamic spatial equilibrium model with heterogeneous households and endogenous migration. Improved connectivity not only accelerates urbanization but also increases aggregate rural output by 2.2%–5.3% in the long run, even as the rural workforce declines.

Singapore In Global Value Chains: Implications Of The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen

Research Collection School Of Economics

This paper examines Singapore’s structural position in global value chains (GVCs) and the implications of the second Trump administration’s tariff escalation for Singapore and the broader ASEAN region. We proceed in three parts. First, using the ADB Multi-Regional Input–Output (MRIO) tables for 2019 and 2024, we characterise Singapore’s GVC participation and position. Singapore is the most GVCintensive economy in ASEAN, with nearly half of its gross exports comprising foreign value-added and a markedly downstream orientation. China is its dominant upstream partner across manufacturing and services—intermediating over 27% of foreign content in electronics and over 10% in chemicals—while Malaysia, Taiwan, and …

Marital Stability And Intrahousehold Inequality, Tomoki Fujii, Xirong Lin, Jacob Penglase

Research Collection School Of Economics

We study what predicts marital instability using a unique dataset from Japan with detailed measures of spouses’ consumption, savings, labor supply, satisfaction, and marriage-market conditions. We combine descriptive survival and event-study analyses with several econometric and machine-learning approaches, including Cox proportional-hazards models and DynForest, a method designed for survival data with time-varying covariates. Across these approaches, match quality, household resources, time use, stated satisfaction, and marriage-market conditions all contain predictive information. Our main contribution is to show that intrahousehold consumption allocation matters, highlighting information that is missed by standard demographic, time use, and income measures. We relate these findings to …

Laponite Nanosilicate As A Platform For Antigen–Adjuvant Co-Delivery In Vaccination, Haoyu Qi

McKelvey School of Engineering Graduate Student Theses & Dissertations

Nanosilicates are two-dimensional, charged nanomaterials with tunable surface chemistry that enable electrostatic interactions with proteins and nucleic acids. These properties make Laponite nanosilicate a promising platform for vaccine delivery, where coordinated antigen–adjuvant presentation and lymph node delivery are important for shaping immune responses. This thesis investigated nanosilicates as scaffolds for lysozyme-based antigen delivery and co-delivery with CpG.

The preparation method reduced the apparent size of the NS–Lys–CpG complex at pH 10, although neutralization to pH 7 promoted larger aggregate formation. In vivo IVIS imaging after footpad injection showed persistent Cy7-associated fluorescence at the injection site for up to three weeks …

Dissecting Ms4a4a Function In Microglia And Its Role In Alzheimer’S Disease Pathogenesis, Emma Pascal Danhash

Arts & Sciences Graduate Student Theses and Dissertations

Genome-wide association studies have begun to uncover the complex genetic architecture of Alzheimer's disease (AD). Expression of many AD risk loci is enriched in microglia, the resident immune cells of the brain. Common variants near the MS4A gene family have been associated with AD risk and altered soluble triggering receptor expressed on myeloid cells 2 (sTREM2) levels in the cerebrospinal fluid (CSF). MS4A4A is a microglial gene that encodes a tetraspan membrane protein that regulates anti-inflammatory responses in macrophages. However, the mechanism by which MS4A4A contributes to microglial function and AD pathogenesis remains unknown. In this dissertation, I leveraged a …

The Stories Of College Faculty Navigating Student Trauma Disclosures: A Narrative Inquiry, Samantha Daluz

LSU New Orleans Theses and Dissertations

The purpose of this narrative inquiry was to understand how faculty who navigate student trauma disclosures construct stories about themselves as educators and how those stories shape their understanding of teaching and learning. Although the literature has increasingly focused on trauma-informed approaches to teaching and learning, little research has explored how faculty navigate student trauma disclosures or how those experiences shape their understanding of teaching and learning. This study sought to better understand those experiences and provide institutional leaders with insight into how faculty experience student trauma disclosures within higher education. Narrative inquiry was employed using Mahayana Buddhism as the …

Defining The Value Of Elective Lumbar Fusion: A Systematic Review Of Existing Methodologies And Framework For The Operative Value Index, Advith Sarikonda, Anthony Chen, Theo S. Biddle, Danyal A. Quraishi, Preston Carey, Arbaz A. Momin, Matthews Lan, Dwight Mitchell Self, Ashmal S. Kabani, Ahilan Sivaganesan

Department of Neurosurgery Faculty Papers

BACKGROUND: Despite wide variation in the outcomes and costs of lumbar fusion, few studies have integrated these domains together within a single metric to assess "value" (outcomes achieved per dollar spent). In this review, we sought to 1) characterize existing metrics of cost-effectiveness for lumbar fusion, 2) evaluate all applications of time-driven activity-based costing (TDABC) in spine surgery, and 3) outline the conceptual foundation for a standardized Operative Value Index (OVI).

METHODS: Two PRISMA-concordant systematic reviews were performed on PubMed and Scopus databases. The first review examined all studies which reported a cost-effectiveness metric for lumbar fusion. The second review …
