Global Youth Development: Challenges And Remedies, Raymond Chimezie

Faculty Publications and Presentations

Young people have enormous potential for growth and innovation, but not all have access to resources and opportunities to explore, achieve their dreams, and contribute immensely to society. Absence or limited opportunities and resources pose great challenges to young people’s aspirations. Through a review of literature and study of some countries young people globally face challenges, though at varying degrees like unemployment, limited access to healthcare, social services, and education; lack of professional support, skills acquisition and retraining, and political exclusion; judicial inequity, loneliness, and poor parenting. There still exist policies, structures, or regulations that encourage racial and ethnic or …

Cytosignal Detects Locations And Dynamics Of Ligand-Receptor Signaling At Cellular Resolution From Spatial Transcriptomic Data, Jialin Liu, Hiroaki Manabe, Weizhou Qian, Shion Orikasa, Javid Ghaemmaghami, Yichen Wang, Yichen Gu, Angel Ka Yan Chu, Gaurav Gadhvi, Yuxuan Song, Patrick Mcclinden, Vibha N Lama, Noriaki Ono, Joshua D Welch

Faculty, Staff and Student Publications

Cells communicate through ligand-receptor (LR) signaling interactions, but identifying when and where these interactions are active remains challenging. We developed CytoSignal to infer the locations and dynamics of cell-cell communication at cellular resolution from spatial transcriptomic data. Here we show that our cellular resolution, spatially resolved signaling scores enable several important analyses-identifying spatial gradients in signaling strength, quantifying the locations of contact-dependent and diffusible interactions, detecting signaling-associated genes and identifying differential signaling across multisample data. Additionally, we can predict the temporal dynamics of a signaling interaction at each spatial location. We experimentally validate our results in situ by proximity ligation …

Evidence Brief: Shifting Attitudes And Social Norms On Fgm Through Community-Based Interventions In Isiolo And Narok Counties Of Kenya, Stella Muthuri, Dennis Matanda, Francis Obare, Robert Omondi, Stephen Kizito, Chi-Chi Undie

Sexual and Reproductive Health, Rights, and Choices

The Girl Generation: Support to the Africa-Led Movement (TGG-ALM) programme in Kenya demonstrates that community-based, dialogue-driven interventions can shift social norms, attitudes, and behavioural intentions related to female genital mutilation (FGM), while also strengthening gender-equitable beliefs. Drawing on evidence from Isiolo and Narok counties, this evaluation shows that exposure to intergenerational dialogues, women’s reflection circles, and couple-based engagement is associated with stronger personal opposition to FGM, increased acceptance of uncut girls, and greater willingness to abandon the practice.

Strategic Communication For Population Stabilization: From Narrative To Sbcc Action, Population Council Pakistan

Sexual and Reproductive Health, Rights, and Choices

The Population Council led a landmark national effort to redefine population discourse in Pakistan through the development of a unified, rights-based national narrative—Tawazun (Balance). This narrative, endorsed by the Federal Task Force on Population and adopted at the highest policy forums, reframed population from a fragmented and sensitive issue into a shared national development priority. Tawazun established a clear framework—balancing rights, responsibilities, and resources—positioning family planning within the broader goals of family well-being, human development, and national sustainability. Importantly, the narrative was formally adopted by federal and provincial governments, and integrated into policy frameworks, communication strategies, and development planning processes.

Assessing Family Planning Progress In Exemplar Countries: Development Of A Conceptual Framework And Case Study Methodology, Zahid Memon, Hina Najmi, Abeer Mian, Sacha Ahmad, Muhammad Islam, Kevin Samuel, Marleen Temmerman, Ali Mohammad Mir, Zeba Sathar

Centre of Excellence in Women and Child Health

Family planning (FP) is a critical component of reproductive health, enabling individuals to plan the number and timing of children through various contraceptive methods.

We outline the conceptual framework and country case study methodology used by the Exemplars in Family Planning (EFP) project. This was based on the wider Exemplars in Global Health programme, which uses mixed-methods to examine determinants of FP progress in countries that exceed expectations for health outcomes. The EFP project integrates findings from case studies on six such countries, including quantitative analyses of trends and drivers of modern contraceptive prevalence, systematic reviews, policy, programme and financing …

Communicative Administration: The Administrative State Beyond Legal Administration, Daniel E. Walters

Faculty Scholarship

On many dimensions, the administrative state is at the nadir of its power. The Supreme Court has tightened administrative law controls on agency power, and the Trump Administration has stormed the bureaucracy in an unprecedented blitz designed to kneecap agency capacity and independence. For better or worse, many agencies and their civil servants are being sidelined as meaningful actors in the administration of government. Yet this familiar account doesn’t tell the entire story. At the same time that agencies are being stripped of the power to implement law—what this Article calls “legal administration”— they are steadily accumulating extensive and largely …

Compellingness In Nash Implementation, Shurojit Chatterji, Takashi Kunimoto, Paulo Daniel Salles Ramos

Research Collection School Of Economics

A social choice function (SCF) is said to be Nash implementable (in pure strategies) if there exists a mechanism in which every pure-strategy Nash equilibrium induces outcomes specified by the SCF. The main objective of this paper is to assess the impact of considering mixed-strategy equilibria in Nash implementation. We define compelling Nash implementation as a case where the implementing mechanism possesses a pure-strategy equilibrium that strictly Pareto dominates any undesired mixed-strategy equilibrium. We show that if the finite environment and the SCF to be implemented jointly satisfy what we call Condition COM, then we can construct a finite …

The system focuses on real-time navigation, model loading, camera movement, and rendering of a low-poly 3D scene. The use of a low-poly visual style helps reduce computational …

The Five Cs Of Positive Youth Development In Singapore: Building Adolescent Resilience, Teresa Theodora Jing Yi Tan, Li Neng Lee

Journal of Youth Development

The Five Cs of Positive Youth Development (PYD) model is one of the most empirically discussed frameworks on youth thriving. Generalisability of the model was investigated among 210 middle (15-18 years old) and 250 late (19-25 years old) adolescents in Singapore. The Five Cs of PYD was evaluated as a mediator between intentional self-regulation, social-emotional competencies and family functioning, and the outcome of adolescent resilience. Results validate the model among youths in Singapore and show that the Five Cs of PYD positively predict adolescent resilience. The study extends the global application of the model while highlighting the need to consider …

Strategic Sustainability In Fast-Fashion: Consumer Responses To Green Collections, Caroline Le Bon

Journal of Applied Marketing Theory

The fashion industry has long been criticized for its detrimental environmental impact. As awareness grows, consumers acknowledge that their demand for variety at low prices has fueled the industry’s unethical practices, making sustainability a key concern for them and for companies. Although fast-fashion brands introduce sustainable collections, they continue to face criticism for prevalent greenwashing practices. Our research explores how integrating such collections into fast-fashion assortments influences consumer perception and purchase intention, depending on their involvement in both fashion and sustainability. Through our quantitative study, we find that implementing strategic sustainability through green collections alone is insufficient to convince environmentally …

How The Dod Discourages Military Families From Seeking Mental Health Counseling, Christina Welch

Seattle University Law Review

The Department of Defense’s (DoD) administration of the Exceptional Family Member Program (EFMP) presents significant barriers to mental health care access for military spouses and children. This paper explores how the EFMP, though designed to support military families with special needs, inadvertently creates barriers to mental health treatment. Military family members often do not seek mental health treatment to avoid the program's mandatory enrollment requirements. Military family members often view enrollment in the program undesirable because enrollment can restrict the pool of potential future duty assignment locations that are available to service members.

The lack of comprehensive data collection by …

2025, Richard Delgado

Seattle University Law Review

"In a cutting and provocative social critique in one of the more extended Rodrigo Chronicles, Richard Delgado in 2025 employs skillful narrative—one of CRT’s many contributions to legal scholarship —to tell a gripping story of just how far the nation has descended into darkness with President Trump’s re-election. In Delgado’s vision, law professors—along with other political opponents of the President: immigrants, people of color, LGBTQ+ people, women, the underserved—have targets on their backs."

The Preventative Care Gap: Completing The Aca’S Vision For Health, Abby Nagaich

Seattle University Law Review

This Note examines the preventive care mandate under the Affordable Care Act (ACA) and the legal, political, and practical challenges that threaten its effectiveness. While the ACA significantly expanded access to no-cost preventive services, gaps remain—particularly in behavioral health, obesity management, and equitable service delivery. Ongoing litigation, potential administrative rollbacks, and shifting political leadership further destabilize this critical component of public health policy.

This Note argues that for the ACA to fulfill its original promise—and for any health framework to succeed—preventive care must be redefined as a comprehensive, early intervention approach grounded in both systemic access and patient education. It …

Scu2u, Sattvika Bhatt, Austin Nguyen, Dhruv Patel, Izzy Perez, Shaunak Sharma

Computer Science and Engineering Senior Theses

On college campuses, the lack of short-range delivery options creates frequent distractions and interruptions, reducing productivity and convenience for students and faculty.

The system utilizes a client-server network architecture that enables remote processing and monitoring over a campus Wi-Fi network.

The rover uses a 2D LiDAR sensor to scan its environment and utilizes SLAM (Simultaneous Localization and Mapping) to build and localize with a reference map of its environment. Autonomous navigation is implemented using ROS2 and the Nav2 framework, which …

A Polygon Approach For Satellite Coverage Computation Problems, Caleb I. Arbreton

Master's Theses

During celestial body observation mission planning, predicted sensor coverage is a key analysis tool used by designers to inform concept of operations. It enables trade studies by applying a metric to assess how well different sensor, satellite, and constellation configurations can observe a mission's region of interest. The effectiveness of the studied components is then paramount in determining whether they are justified in the system architecture. Coverage computation becomes more difficult as sensor types and regions of interest (RoIs) deviate from simple shapes, and as problem formulations seek higher-fidelity results. These simplifications include: conical camera sensors, RoIs represented as simple, …

Dot Product Engine Based Neuromorphic Hardware For Continuous-Time Biomedical Signal Classification, Sanjeev Srinivasan

Master's Theses

Accurate diagnosis of pathological conditions from biomedical signals, such as electrocardiograms (ECGs) is often performed offline, making it time-consuming, costly, and inefficient, especially when abnormal patterns are rare and long-term monitoring generates large amounts of data. To address this, this work proposes a compact, scalable, and programmable neuromorphic system designed for real-time preliminary arrhythmia detection and classification using ECG signals, that can be extended to other biomedical signals. The proposed design processes ECG signals using a delta modulation-based spike encoder, followed by classification with a dot-product engine (DPE) based spiking neural network (SNN) processor and winner-take-all (WTA) circuit. The architecture …

Optimization Of Repeat Ground Track Constellation Design For Complex Discontinuous Regional Coverage, Paige Jewell

Master's Theses

The continued growth of low Earth orbit (LEO) satellite constellations motivates efficient constellation design methods to reduce cost and complexity. Although brute-force methods are commonly employed in the preliminary design of satellite constellations, pairing analytic methods with optimization algorithms provides a more efficient means of searching the design space. Constellation design for continuous global and regional coverage is well-established; however, strategies for discontinuous regional coverage remain underdeveloped. This thesis focuses on an analytic geometry-based method for computing satellite coverage and revisit metrics, coupled with genetic algorithm optimization to efficiently explore the design space. The viability of this method is shown …

`Youdrawitr`: Integrating Interactive Graphical Testing Into The `Ggplot2` Ecosystem, Alisa Krasilnikov

Master's Theses

`youdrawitR` is an R package inspired by the New York Times ‘You Draw It’ series, where readers are invited to sketch their own predictions before seeing the actual data. In a similar spirit, `youdrawitR` allows users to draw predicted values directly onto statistical graphics, creating a more engaging way to study how people interpret visual patterns. Earlier versions of the tool required knowledge of JavaScript D3 to extend or adapt the package, which created a barrier to entry for many statistical researchers. Further, the package was limited in scope, supporting only scatterplots. The redesigned `youdrawitR` builds on the familiar `ggplot2` …

These navigational commands are created using relative localization data gathered and processed onboard the sensor package, with validation, in post-processing, against global localization data. This research aims to reduce the cost of smaller autonomous vehicles by removing the need for custom control units, as its modular nature will allow it to be adapted to many different systems and vehicles. Discussed within this thesis is the rapid prototyping, development, and testing …

Effects Of Atomic Oxygen Exposure On Stressed Drag Sail Materials For Low Earth Orbit Applications, Nazanin Sadeghian Dezaki

Master's Theses

As low Earth orbit (LEO) has become an increasingly valuable region for satellite operations, it has grown increasingly congested. The Federal Communications Commission (FCC) deorbit regulations require satellites to be deorbited within 5 years of launch, and drag sails represent a practical means of meeting this requirement. An important consideration for drag sail design is the effect of atomic oxygen (AO) on sail materials. To address the gap in the literature regarding the behavior of stressed drag sail materials under AO exposure, a new test plate was manufactured for the California Polytechnic State University minimum atmospheric experimentation (MAX) AO chamber. …

Computer Vision Methods For Detecting Counterfeit Usd Bills, Tyler W. Jones

Master's Theses

This thesis addresses the global challenge of counterfeit paper currency by proposing a classical computer vision framework for distinguishing genuine United States Dollar (USD) bills from counterfeit ones using image data. In contrast to existing approaches that rely on a large number of easily reproducible visual features, this work prioritizes the detection of a single, robust security feature: the ultraviolet (UV) reactive security strip embedded in genuine USD bills of denominations $5 and above. By focusing on a feature that is inherently difficult to replicate, the proposed method reduces the likelihood of counterfeit bills being misclassified as genuine.

The system …

Investigating The Structural Barriers And Opportunities For End-Of-Life Management Of Agricultural Plastic Waste Within California's Strawberry Industry, Rory M. O'Toole

Master's Theses

Agricultural plastic waste (APW) accounts for a significant and growing share of global plastic pollution, yet no study has documented how APW management functions across a specific crop system from production through end-of-life (EOL). This thesis addresses that gap by examining the structures and valuations that shape current EOL management of plastic mulch (PM) and drip tape (DT) in California's strawberry industry, one of the nation's most plastic-dependent crop systems. Drawing on an ethnographic approach that included 27 semi-structured interviews with stakeholders, as well as site visits, this study traces how APW is produced, valued, and discarded within a structurally …

Prototype X-Band Front End Upconverter & Transmitter With An Integrated Pll, Mont Ziadoon Murad

Master's Theses

In recent years, there has been growing interest in high-speed communication for small satellites. Achieving higher communication speeds will enable any experimental CubeSat to conduct experiments at higher rates and allow further research into SAR and deep-space exploration. At Cal Poly, the CubeSat Lab has mainly operated at 9600 baud and utilized the Ultra High Frequency (UHF) amateur radio band. While it has proven itself resilient, the UHF band lacks the infrastructure to support higher-bandwidth communication systems. To address this gap, this work presents a prototype space-side downlink RF front end comprising an upconverter, a power amplifier (PA), and a …

In hardware, the feasibility of a cascaded reaction wheel control architecture is experimentally demonstrated, achieving …

Trustworthy Intelligence Fusion For Search And Rescue: Designing Grounded And Secure Multi-Agent Ai For Mission Decision Support, Yayun Tan

Master's Theses

Search and rescue (SAR) operations require teams to integrate uncertain information under severe time pressure. Large language model (LLM)-based multi-agent systems (MAS) can support decision-making, but they also risk producing hallucinated outputs and processing unreliable or malicious data. This thesis addresses these risks through three linked studies. First, it proposes a modular eight-agent SAR MAS architecture that reflects the structure of real SAR missions by assigning specialized roles to different agents. Second, it introduces a post-hoc probabilistic verification framework that checks LLM agent outputs against a probabilistic knowledge graph built from historical SAR incidents.  Third, the thesis examines indirect adversarial …
