Youth Program Fy2025 Evaluation Report, Madhawa Palihapitiya, Karina Zeferino

Massachusetts Office of Public Collaboration Publications

A School Climate Needs Assessment completed by 57 administrators evaluated both overall school climate and the key components that contribute to it. Administrators revealed low satisfaction with overall school climate (25%) and with students’ SEL skills (19%), and most considered these areas important to improve (77% and 79%) and expressed a desire for support (60% and 53%). Similar patterns emerged for academic performance (28% satisfied; 86% considered improvement important; 44% desired support), disciplinary actions (19%; 54%; 49%), and conflict levels—student-student (21%; 79%; 60%) and student-teacher (26%; 49%; 47%). Across these domains, a substantial proportion of respondents—often …

“Are There Any British Soldiers In Tobruk?” National Identity During The Siege Of Tobruk, May To November 1941, Stewart Golightly Weight

All Graduate Theses and Dissertations, Fall 2023 to Present

Throughout this thesis, I examine what it meant to be British during the 1941 Siege of Tobruk. This is important as it reveals previous assumptions about the Second World War’s British Army, including its religious practices and regional distinctions, were more diverse and influential than previously assumed. To do this, I analyze previously overlooked sources concerning religion, morality, and regional identities to demonstrate that Second World War Britishness was not monolithic.

Social Media Mining For Extracting The Experience Of Neurodivergent Individuals On Twitter (X) And Reddit, Kartik Thakkar

All Graduate Theses and Dissertations, Fall 2023 to Present

Neurodiversity refers to the natural neurological variations in the human brain such as autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), dyslexia, dyspraxia, Tourette syndrome and other neurological disorders. it’s estimated that around 15% to 20% of the world’s population is neurodivergent. This means a significant portion of people experience neurological differences in how they think, learn, and interact with the world.

Social Media has become an important space for neurodivergent individuals to share their experiences, build communities, and seek support. This thesis explores how the online venues like X (Twitter) and Reddit offer themselves as digital spaces where …

Using Behavioral Skills Training To Teach School Staff To Implement Functional Communication Training, Megan Johnston

All Graduate Theses and Dissertations, Fall 2023 to Present

This project looked at how to train school staff in effective strategies for supporting students with disabilities who engage in challenging behaviors like hitting, self-injury, or crying. We taught three school staff members to use a behavioral intervention called Functional Communication Training (FCT), which helps students learn more appropriate ways to communicate their needs, while also ensuring they do not gain access to reinforcement for challenging behaviors. Staff were trained using Behavioral Skills Training (BST), a step-by-step approach that includes instructions, modeling, practice, and feedback. After the training, the school staff were able to use these strategies correctly, and the …

A Learning‑Augmented Dynamic Programming Approach For Orienteering Problem With Time Windows, Guansheng Peng, Lining Xing, Fuyan Song Ma, Aldy Gunawan, Aldy Gunawan

Research Collection School Of Computing and Information Systems

Recent years have witnessed a surge of interest in solving combinatorial optimization problems (COPs) using machine learning techniques. Motivated by this trend, we propose a learning-augmented exact approach for tackling an NP-hard COP, the Orienteering Problem with Time Windows, which aims to maximize the total score collected by visiting a subset of vertices in a graph within their time windows. Traditional exact algorithms rely heavily on domain expertise and meticulous design, making it hard to achieve further improvements. By leveraging deep learning models to learn effective relaxations of problem restrictions from data, our approach enables significant performance gains in an …

Riding Attention Spikes: How Analysts Respond To Advertising, Minjae Koo, Annika Yu Wang, Yin Wang, Liandong Zhang

Research Collection School Of Accountancy

Product market advertising, while containing little new information, triggers spikes in investor attention. Using weekly advertising data, we find that sell-side analysts issue optimistic earnings forecasts in response to heavier advertising in the prior week. This effect is not driven by confounding earnings or product news. It is more pronounced for experienced analysts and analysts affiliated with brokerages relying solely on trading revenues. The optimistic forecast bias intensifies the impact of advertising on investor trades, especially on retail buying, of the underlying stock during the following week. Overall, analysts appear to issue optimistic forecasts to exploit retail investor attention spikes …

Agentguard: An Active Threat Discovery System For Package Confusion Using Multi-Agent Collaboration, Wei Ma, Yu Li, Zhi Chen, Ye Liu, Lingxiao Jiang, Qiang Hu, Junyi Tao

Research Collection School Of Computing and Information Systems

The proliferation of open-source software (OSS) has made software supply chains prime targets for attacks like Package Confusion, where adversaries publish malicious packages with names deceptively similar to legitimate ones. Existing detection methods often rely on simple lexical similarity or passive analysis of known package pairs, struggle with high false positive rates (FPR), fail to proactively identify emerging threats, and are vulnerable to adversarial evasion. To overcome these limitations, we introduce AgentGuard, a novel framework for proactive, single-input package confusion detection. AgentGuard employs a multi-agent architecture that autonomously discovers potential confusion targets using fine-tuned word embedding model to hybird semantic …

Registration Is A Powerful Rotation-Invariance Learner For 3d Anomaly Detection, Yuyang Yu, Zhengwei Chen, Xuemiao Xu, Lei Zhang, Haoxin Yang, Yongwei Nie, Shengfeng He

Research Collection School Of Computing and Information Systems

3D anomaly detection in point-cloud data is critical for industrial quality control, aiming to identify structural defects with high reliability. However, current memory bank-based methods often suffer from inconsistent feature transformations and limited discriminative capacity, particularly in capturing local geometric details and achieving rotation invariance. These limitations become more pronounced when registration fails, leading to unreliable detection results. We argue that point-cloud registration plays an essential role not only in aligning geometric structures but also in guiding feature extraction toward rotation-invariant and locally discriminative representations. To this end, we propose a registration-induced, rotation-invariant feature extraction framework that integrates the objectives …

Rising From Ashes: Generalized Federated Learning Via Dynamic Parameter Reset, Jiahao Wu, Ming Hu, Yanxin Yang, Xiaofei Xie, Zekai Chen, Chenyu Song, Mingsong Chen

Research Collection School Of Computing and Information Systems

Although Federated Learning (FL) is promising for privacy-preserving collaborative model training, it suffers from low inference performance due to heterogeneous client data. Due to heterogeneous data across clients, FL training easily learns client-specific overfitting features. Existing FL methods adopt coarsegrained averaging, which can easily cause the global model to get stuck in local optima, leading to poor generalization. Specifically, this paper presents a novel FL framework, FedPhoenix, to address this issue. It stochastically resets partial parameters in each round to destroy some features of the global model, guiding FL training to learn multiple generalized features for inference rather than specific …

Instance-Level Video Depth In Groups Beyond Occlusions, Yuan Liang, Yang Zhou, Ziming Sun, Tianyi Xiang, Guiqing Li, Shengfeng He

Research Collection School Of Computing and Information Systems

Depth estimation in dynamic, multi-object scenes remains a major challenge, especially under severe occlusions. Existing monocular models, including foundation models, struggle with instance-wise depth consistency due to their reliance on global regression. We tackle this problem from two key aspects: data and methodology. First, we introduce the Group Instance Depth (GID) dataset, the first large-scale video depth dataset with instance-level annotations, featuring 101,500 frames from real-world activity scenes. GID bridges the gap between synthetic and real-world depth data by providing high-fidelity depth supervision for multi-object interactions. Second, we propose InstanceDepth, the first occlusion-aware depth estimation framework for multi-object environments. Our …

Efskip: A New Error Feedback With Linear Speedup For Compressed Federated Learning With Arbitrary Data Heterogeneity, Hongyan Bao, Pengwen Chen, Ying Sun, Zhize Li

Research Collection School Of Computing and Information Systems

Due to the communication bottleneck in distributed and decentralized federated learning applications, algorithms using compressed communication have attracted significant attention. The Error Feedback (EF) is a widely-studied compression framework for convergence with biased compressors such as top-k sparsification. Although various improvements have been obtained in recent years, the theoretical guarantee for EF-type framework is still limited. Previous works either 1) rely on strong assumptions such as bounded gradient/dissimilarity assumptions, thus can not deal with arbitrary data heterogeneity and also slow the convergence speed, or 2) can not enjoy linear speedup in the number of clients. In this work, we propose …

Scalable Graph Indexing Using Gpus For Approximate Nearest Neighbor Search, Zhonggen Li, Xiangyu Ke, Yifan Zhu, Bocheng Yu, Baihua Zheng, Yunjun Gao

Research Collection School Of Computing and Information Systems

Approximate nearest neighbor search (ANNS) in high-dimensional vector spaces has a wide range of real-world applications. Numerous methods have been proposed to handle ANNS efficiently, while graph-based indexes have gained prominence due to their high accuracy and efficiency. However, the indexing overhead of graph-based indexes remains substantial. With exponential growth in data volume and increasing demands for dynamic index adjustments, this overhead continues to escalate, posing a critical challenge.In this paper, we introduce Tagore, a fasT library accelerated by GPUs for graph indexing, which has powerful capabilities of constructing refinement-based graph indexes such as NSG and Vamana. We first introduce …

Llm-Assisted Cwe Identification, Severity Assessment, And Vulnerability Description Generation, Mohammad Jalili Torkamani

School of Computing: Dissertations, Theses, and Student Research

Identifying the underlying weakness types and assessing their severity using CWE and CVSS standards are critical steps in software vulnerability management. While timely assessment of vulnerabilities mitigates the impact of severe security incidents, automating joint CWE identification and severity assessment remains challenging due to the heterogeneity of vulnerabilities across different code granularities and programming languages. In addition, generating vulnerability descriptions is often time-consuming, as it requires extensive manual review, validation, and writing by security experts.

In this thesis, we leverage the capabilities of Large Language Models (LLMs) to automate the identification of CWE identifiers and the assessment of their severity …

Flood Resilience Through Working-Land Conservation: Assessment Of Wetland Inundation Dynamics Across Wrp, Wma, Wpa, Padus And Crp Lands In Nebraska (2018–2024), Pranjay Joshi

Community and Regional Planning Program: Theses

This study first confirms whether Nebraska’s wetlands are still functioning hydrologically in ways that reduce flood impacts. Wetlands are known to lessen flood damage by storing water, slowing runoff, and moderating peak flows, but these benefits depend on the wetlands’ ability to maintain inundation and saturation through time. Many wetlands across the state have undergone drainage, hydrologic alteration, or isolation from surrounding watersheds, raising uncertainty about their present-day functioning. Using seven years of Sentinel-2 imagery processed in Google Earth Engine, this research establishes a clear, long-term record of inundation patterns across thousands of wetland parcels. This analysis verifies which wetlands …

Review: Poetter, Thomas S. Curriculum Fragments: A Currere Journey Through Life Processes., Joseph Wiederhold

The Journal of the Assembly for Expanded Perspectives on Learning

Poetter’s book Curriculum Fragments—and the stories shared within— have changed the way I think about education. Redefined it. Recentered it on what matters most—the human experience, the life processes at the center of Poetter’s book: losing, knowing, forgiving, relating, hoping, growing, loving. Each of Poetter’s fragments—reflective narratives written following the Currere methodology (Pinar)—caused me to reevaluate my practice.

A Faith-Based Approach To Mental Health Challenges, Patrick Leblanc

Doctor of Ministry Theses and Dissertations

ABSTRACT

This project sheds light on mental health issues within the Black community and the need for faith communities to intentionally address mental health issues in communities of color. Black men are oppressed by an interplay of cultural, historical, societal, and economic factors that impact their well-being. Racial discrimination and oppression are non-medical drivers exacerbating mental health disorders among Black men. The influences of culture and faith fabricate barriers to help-seeking behavior, and mistaken perceptions of masculinity cause many men to suffer in silence. To begin erasing derogatory perceptions of mental health disorders, faith communities need to increase mental health …

Improving The Effectiveness Of The Teacher Professional Learning Communities In Secondary Education, Oscar A. Urieta

Education Theses and Dissertations

This Improvement Science Dissertation in Practice investigated how to enhance the relevance, effectiveness, and teacher ownership of grade-level Professional Learning Communities (PLCs) at a university-affiliated charter school in East Texas. Despite the district’s strong STEM and Project-Based Learning (PBL) emphasis, 60% of high school teachers reported that PLCs felt irrelevant, administratively driven, or misaligned with their daily instructional needs. Using Improvement Science methodologies, including Plan-Do-Study-Act (PDSA) cycles, root-cause analysis, a driver diagram, and embedded collaborative structures, this study implemented targeted interventions aimed at shifting teacher perceptions and strengthening PLC practices. Interventions centered on aligning PLC agendas with PBL, implementing structured …

Freshwater Turtle Assemblages And Densities In Agricultural Ditches And Aquaculture Ponds Of Eastern Arkansas, Andrhea D. Massey, John D. Willson, Brett A. Degregorio

Biological Sciences Faculty Publications and Presentations

The Mississippi Alluvial Plain (MAP) of Arkansas is a landscape where many wetlands have been altered for use as aquaculture ponds or agricultural ditches. Commercial harvest of freshwater turtles within the MAP is not restricted or limited, with reported harvest numbers for 2019 alone exceeding 4000 for spiny softshell turtles (Apalone spinifera) and 39,000 for red-eared sliders (Trachemys scripta elegans). Herein, we attempt to provide baseline estimates of freshwater turtle densities and community composition in aquaculture ponds and agricultural ditches of eastern Arkansas, the habitat types most frequently trapped by commercial harvesters. We used a capture-mark-recapture approach over 3 summers …

Local Government Standing As State Standing, Katharine Cooney, Katherine Mims Crocker

Faculty Scholarship

It is increasingly common, and controversial, for local governments to bring lawsuits as plaintiffs in federal court. Many questions about this practice raise matters that sound in policy. But some, including the issue of standing to sue, also raise issues of constitutional law. How local governments fit into standing rules should reflect how they fit into the U.S. constitutional system more broadly. As the Supreme Court put it in the famous (and infamous) 1907 case Hunter v. City of Pittsburgh, "[m]unicipal corporations are political subdivisions of the State, created as convenient agencies for exercising such of the governmental powers of …

Purpose And Nonprofit Enterprise, Cathy Hwang, Dorothy S. Lund

Faculty Scholarship

Nonprofit enterprise is responsible for a large share of economic activity across the globe. And yet, leading theories fail to explain why nonprofit business survives and even thrives across a vast number of industries, ranging from artificial intelligence to beer brewing, despite an absence of shareholder control. Indeed, as shareholder ownership and intervention rights have become the core component of successful corporate governance, this success is all the more surprising.

This Essay offers a novel “purposeful enterprise” theory to explain the puzzling success of nonprofit enterprises. Drawing on research in behavioral economics and organizational science, it argues that organizational purpose …

Sex And Danger, Airborne Ranger: A Historical Analysis Of G.I. Songs, Jody Calls, And Marching Cadences, Travis G. Salley

Dissertations

Military marching cadences have long served as a core feature of basic combat training, reinforcing cohesion, discipline, and esprit de corps. Tradition attributes their origin to a Black soldier, Private Willie Duckworth, who lifted the spirits of his unit with an improvised chant during a 1944 forced march. The chant soon gained national attention and was formally adopted into Army training through the efforts of Colonel Bernard Lentz—Duckworth’s commanding officer and the author of the Army’s close order drill manual. Their relationship, framed by military hierarchy and racial inequality, reflects broader American patterns where Black cultural forms gain institutional legitimacy …

This study examines intercultural competence (the ability to interact respectfully and effectively across cultures) among participants in the first Young South Asian Leadership Initiative (YSALI) program. Using the Intercultural Development Inventory and follow-up interviews, investigators considered how well these emerging leaders from seven South Asian countries were prepared to lead in multicultural environments. This article presents a preliminary report, based on early survey returns from 15 of 82 participants. This research will provide important insights into …

Impact Of Equipment Type On Measured Particle Size Of Civil Engineering Materials, Tanner Turben, Tasnimul R. Ferdous, Andrew Braham, Wen Zhang

Civil Engineering Faculty Publications and Presentations

Particle size analysis (PSA) captures the size distribution of finely graded materials with particles generally smaller than 1000 microns. Many civil engineering materials do not leverage PSA for material specifications or acceptance despite the insight into material performance and quality gained through understanding the particle size. The objectives of this study are to compare PSA measurement principles by testing 13 civil engineering materials by laser diffraction, Coulter counter, and microscopy. Asphalt emulsions, cementitious materials, sands, clays, and biological samples were selected to represent a wide set of interests and shapes. It was found that between laser diffraction and Coulter counter …

Barriers To Hospice Access For The Latino Community, Guadalupe Rivera

Capstone Projects and Master's Theses

The Latino community in Monterey County faces significant obstacles to accessing hospice care, including language barriers and cultural misunderstandings. Many community members are unfamiliar with available hospice services or hold common misconceptions, such as equating hospice only with dying or abandonment. This capstone project, in partnership with the Central Coast Visiting Nurse Association (VNA), investigated these barriers through interviews conducted at a local senior event. An important outcome of the project was the creation of a bilingual (Spanish and English) resource guide for new Social workers which helps social workers efficiently connect Latino families to appropriate services in their preferred …

Supporting Self-Regulation In Middle Childhood Through Social-Emotional Building, Karen Jimenez

Capstone Projects and Master's Theses

Children in middle childhood, ages 6–12, may struggle to self-regulate their emotions, behaviors, and thoughts. They are becoming more independent, forming deeper friendships, facing greater academic demands, and experiencing more complex situations. Struggles with self-regulation can lead to difficulties in resilience, peer relationships, and school performance, but children who can identify their feelings, understand their emotional triggers, and recognize how these emotions impact their behavior are better able to cope with challenges and stay focused. According to McCabe and Altamura (2011), children with strong social-emotional skills usually have better relationships, more friends, and greater success in school, while those children …
