Web-Based Pipeline for Standardized Event Window Stock Return Analysis and Research-Ready Visualization

Wed, 4 Mar 2026 00:00:00 +0000

This submission introduces a reproducible web platform that operationalizes event study methodology for equity price impact analysis with minimal user effort. The system is designed for research and classroom settings where consistency, traceability, and rapid iteration are essential. Users provide daily trading data through file upload and specify an event date through the interface. The platform then executes a standardized analytical pipeline that validates and cleans the input, computes daily percentage returns, constructs a fixed event window, and summarizes price impact by contrasting mean returns in the five trading days preceding the event with the five trading days following the event. The platform additionally produces research-ready visualizations that support the interpretation of pre-event anticipation and post-event adjustment dynamics. By replacing manual spreadsheet workflows with a consistent computational procedure, the platform reduces operational error,...

A Market-Oriented Business Model and AI System Design for Multilingual Business Card Intelligence

Wed, 4 Mar 2026 00:00:00 +0000

Business card digitization tools are widely available, yet many solutions remain focused on optical character recognition and contact storage rather than measurable networking outcomes. This paper develops an academic and market-oriented framework for an AI-based multilingual business card intelligence system designed to convert raw card images into structured contacts, prioritized action lists, and AI-assisted follow-up content. The study is motivated by a practical gap between data extraction performance and post-event relationship conversion. Existing literature supports the importance of human-in-the-loop information extraction workflows, privacy-aware data handling, and AI governance, but limited work links these domains to networking operations and event productivity. Using the current prototype design as an empirical design reference, this paper documents the system architecture, key parameters, and a quantitative scoring model for contact prioritization. The system...

Shadows of the Pacific Electric: Former Pacific Electric Rail Lines and Modern California Transit

Wed, 4 Mar 2026 00:00:00 +0000

In the Spring of 1961, the last train of the Pacific Electric Railway left from the Huntington Building on the Pacific Electric Long Beach Line. The former railway has since become the point of focus for transportation planners, historians, and commuters. The Pacific Electric Railway in the 21st century has been the subject of significant romanticization and mythologizing by Californians. In an era where the challenges of daily commutes are becoming increasingly prescient, the Pacific Electric is a reflection of modern desires for modern regional public transit. This story map, maps the former lines of the Pacific Electric and compares them with existing modern public transit connections to visualize the continuity of services between modern transit and the former regional PE. From these comparisons, we can reevaulate the value of the Pacific Electric as a regional connectro and contextualize transit planning in the 21st century.

Amordidas Acompañadas: Deported Recipes of Survival

Wed, 4 Mar 2026 00:00:00 +0000

Amordidas Acompanadas: Deported Recipes of Survival is an autoethnographic and community-engaged project that examines how deported parents and their children re-generate connection through food. My parents were deported on May 9, 2012, one day before Mother’s Day, when I was sixteen years old. They lived in exile in Tijuana for twelve years, staying as close as possible to their children in South Central Los Angeles. The rupture created by this distance grew over time and intensified after my mother passed away in December of 2024. In searching for a way to live with this loss, I turned toward food. Cooking became the method I needed to move forward and understand how deported families survive separation.

This project centers the recipes I learn while cooking side-by-side with deported parents in Tijuana. Each meal carries stories, memories, and strategies of endurance. I turn these meals into recipe cards and bring them back to their children in the United States....

Research-Creation using Open Source Tools: Playing the Archive in Hawk & Puma

Thu, 28 Aug 2025 00:00:00 +0000

Hawk & Puma is a minimalist pixel-art video game developed using open-source tools like Bitsy as part of a doctoral research-creation process. The game reimagines "El Primer Nueva Corónica y Buen Gobierno", a 400-year-old illustrated manuscript written by Felipe Guaman Poma de Ayala—an Indigenous Andean chronicler who denounced colonial violence in 17th-century Peru. This project bridges creative technology, archival research, and community collaboration to explore how digital storytelling can function as both scholarly inquiry and cultural preservation. The game was designed to function as a playable archive: a digital environment where players can engage with Guaman Poma’s ideas through movement, interactivity, and reflection. Pixel art inspired by his original ink illustrations, combined with an ambient Andean-influenced soundtrack, help immerse players in a stylized but critical interpretation of the manuscript. Beyond the game itself, this project...
