Juan Fung, Michael Hall, Jennifer Helgeson, Alden Dima, Anne Andrews, Jennifer Benkstein
This report presents the design and methodology of a survey conducted to evaluate the impact of changes to the organizational publication review policy at the National Institute for Standards and Technology (NIST). The purpose of the survey is to collect

Systematic Review of Embodied Carbon Assessment and Reduction in Building Life Cycles

September 18, 2024
Author(s)
Yating Zhang, Siamak Sattar, Dustin Cook, Katherine Johnson, Juan Fung
The building and construction sector is the largest carbon emitter, accounting for more than one-third of annual global emissions. The emissions can be divided into operational and embodied carbon, associated with building operations and building materials

Human-in-the-loop Technical Document Annotation: Developing and Validating a System to Provide Machine-Assistance for Domain-Specific Text Analysis

May 14, 2024
Author(s)
Juan Fung, Zongxia Li, Daniel Stephens, Andrew Mao, Pranav Goel, Emily Walpole, Alden A. Dima, Jordan Boyd-Graber
In this report, we address the following question: to what extent can machine learning assist a human with traditional text analysis, such as content analysis or grounded theory in the social sciences? In practice, such tasks require humans to review and

Improving the TENOR of Labeling: Re-evaluating Topic Models for Content Analysis

March 23, 2024
Author(s)
Zongxia Li, Andrew Mao, Jordan Boyd-Graber, Daniel Stephens, Emily Walpole, Alden A. Dima, Juan Fung
Topic models are a popular tool for understanding text collections, but their evaluation has been a point of contention. Automated evaluation metrics such as coherence are often used, however, their validity has been questioned for neural topic models

Measuring downstream supply chain losses due to power disturbances

September 16, 2022
Author(s)
Douglas Thomas, Juan Fung
Power outages in the U.S. affect many firms' economic activity and are likely to result in downstream supply chain disruptions. This paper examines the impact of power disturbances in the supply chain for four industries: manufacturing, durable goods

A Framework to Evaluate the Cost-Effectiveness of Recovery-Based Design

May 24, 2022
Author(s)
Juan Fung, Yating Zhang, Katherine Johnson, Dustin Cook, Siamak Sattar
Modern building codes and standards are generally focused on safeguarding public health and safety by ensuring buildings meet life safety performance objectives following an earthquake event. Certain classes of buildings, such as hospitals and schools, may
