Automated Machine Learning For High-Resolution Daily And Hourly Methane Emission Mapping For Rice Paddies Over South Korea: Integrating Modis, Era5-Land, And Soil Data, Jiah Jang, Seung Hee Kim, Menas Kafatos, Jaeil Cho, Gayoung Yoo, Sujong Jeong, Yangwon Lee

Institute for ECHO Articles and Research

Agriculture is a major global source of methane (CH4), and accurate emission estimates are essential for refining national greenhouse gas inventories and supporting climate-resilient policies. This study develops a high-resolution estimation framework for CH4 emissions from Korean rice paddies by integrating multi-source datasets, including Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indices, European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis Version 5 (ERA5)-Land meteorological variables, and Harmonized World Soil Database (HWSD) soil properties. Using CH4 flux observations from four global rice ecosystems (Italy, Japan, South Korea, and USA), we constructed parallel daily and hourly machine learning models using an automated machine …

An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission In A Homogeneous Syringe-Sharing Network, Seun Ale, Que Thi Nguyet Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr.

Reports

The model described in this ODD is an agent-based model of hepatitis C virus (HCV) transmission among people who inject drugs (PWID). The model assumes homogeneous mixing among syringe-sharing agents, without any form of heterogeneity in the agents interactions or syringe-sharing attitude. All syringe-sharing PWID are treated as identical in terms of their interaction frequency and syringe-sharing probability. Interactions are generated dynamically using proximity-based sampling at each timestep (one day), allowing agents to form syringe-sharing interactions based on spatial closeness. The number of daily interaction events is fixed at the population level, and each syringe-sharing agent has the same probability …

An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission With Inter-Group Structural And Behavioural Heterogeneous Syringe-Sharing Networks (M4), Seun Ale, Que Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr.

Reports

The model described in this ODD is an agent-based model of hepatitis C virus (HCV) transmission among people who inject drugs (PWID). The model incorporates structural heterogeneity through a three-group interaction framework and behavioural heterogeneity through group-specific syringe-sharing rates. The syringe-sharing population in the model is divided into core, inner, and outer circle groups representing individuals with high, moderate, and low levels of syringe-sharing interaction intensity, respectively. In addition to differences in the number of daily interaction opportunities across groups, agents in each group are assigned distinct syringe-sharing probabilities, reflecting variation in risk-taking behaviour across structural groups within the syringe-sharing …

Remedying Copyright For Indigenous Australians: A Stolen Generations Perspective, Elizabeth Serventy, Koutras

Research outputs 2022 to 2026

This study presents a Judicial Intersectionality method that incorporates knowledge from arts, humanities, natural sciences, and social sciences. It aims to examine how historical legal, political, and social injustices against Indigenous Australians have persisted in various spheres. When considering the Stolen Generations period, attention is directed on addressing the existing insufficient copyright rights and enhancing future legal results for Indigenous artists. In order to achieve that objective, a unique and distinct copyright system is regarded as the most suitable resolution. Philosophically and pragmatically, this approach was aligned with the Australian Government's 2023 Referendum, which aimed to grant constitutional status to …

Expanding Public Health Insurance To Parents: Effect On Parents' And Children’S Well-Being, Michelle Marcus, Xuan Zhang

Research Collection School Of Economics

Expanding public health insurance to parents may not only improve parental outcomes but also have spillover effects on their children. This paper leverages the natural experiment of the Affordable Care Act (ACA) to estimate the causal effects of expanding public health insurance to low-income parents on their well-being and that of their children. Using a difference-in-differences model and data from the 2010–2017 National Health Interview Surveys, we observe significant improvements in health care access, increased health care utilization, reduced financial burdens, and slight improvements in health status among low-income parents. For children in Medicaid expansion states, we find reductions in …

Bespoke Realized Volatility: Tailored Measures Of Risk For Volatility Prediction, Andrew John Patton, Haozhe Zhang

Research Collection School Of Economics

Standard realized volatility (RV) measures estimate the latent volatility of an asset price using high frequency data with no reference to how or where the estimate will subsequently be used. This paper presents methods for “tailoring” the estimate of volatility to the application in which it will be used. For example, if the volatility measure will be used in a specific parametric forecasting model, it may be possible to exploit that knowledge to construct a better measure of volatility. We use methods from machine learning to estimate optimal “bespoke” RVs for heterogeneous autoregressive (HAR) and GARCH-X forecasting applications. We apply …

The Smu Trade Dashboard: Tracking And Quantifying The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen, Lin Ma

Research Collection School Of Economics

The SMU Trade Dashboard (https://economics.smu.edu.sg/soetrade/tr ade-dashboard), developed by the SMU Center for Research on International Trade, consists of Tariff Tracker and Trade Simulation functions. The Tariff Tracker allows users to track the tariff applicable to an HS 6-digit product or an ISIC 2-digit sector bymarkets and country origins. The Trade Simulation presents quantitative simulation results of the effects of Trump II tariffs (and the associated tariff responses by its trading partners) on trade flows, welfare, and wages. This companion paper documents the methodologies underlying the tariff data collection protocol and the structuralsimulation designs.

Financial Valuation Of Retirement Village Via Stochastic Modelling Of Disability Prevalence Rates, Jackie Li, Mingke Wang, Jia Liu, Jessica Wai Yin Leung

Research Collection School Of Economics

Global mortality rates continue to decline, and life expectancy continues its upward trend. Besides mortality levels, policymakers and providers of financial and health services would also be interested in disability prevalence and its potential future trajectories. The length of time in good health versus the duration with major disabilities or long-term illnesses has significant financial implications for both individuals and society. In this paper, we develop Bayesian common factor models to analyse Australian age- and sex-specific disability prevalence rates. In particular, there are one or more common factors shared by both sexes, as well as specific factors for each sex. …

High Dimensional Regression Coefficient Test With High Frequency Data, Dachuan Chen, Long Feng, Per A. Myklang, Lan Zhang

Research Collection School Of Economics

This paper presents the first study on high-dimensional regression coefficient tests with high-frequency financial data. These tests allow the number of regressors to be larger than the number of observations within each estimation block and can grow to infinity in asymptotics. In this paper, the sum-type test and max-type test have been proposed, where the former is suitable for the dense alternative (many small betas) and the latter is suitable for the sparse alternative (a very small number of large betas). By showing the asymptotic independence between the sum-type test and max-type test, the paper proposes a third test – …

The Lived Experiences Of Deaf People In Carceral Spaces, Grace E. Lester, Gabriel Lomas, Deb S. Guthmann Dr.

JADARA

This qualitative study used semi-structured interviews to examine the experiences of formerly incarcerated deaf people in the carceral system. The examination of lived experiences in this research offers a context to the belief that the carceral system is structurally unqualified to address the significant, but nuanced needs of deaf people. This study counters the neglect of the intersectional experiences of incarcerated deaf people that exists in research literature by providing them the opportunity to share their stories in their own words through in-depth semi-structured interviews. Five previously incarcerated deaf adults were interviewed using a digital video platform. Using phenomenological methods, …

Diagnostic Trends And Service Enhancements In Deaf Mental Health: A Longitudinal Analysis, Kent Schafer, Steve Hamerdinger, Frank Wu, Rie Sakai Bizmark, Charlene Crump

JADARA

A longitudinal study investigated mental health diagnostic trends and patterns among Deaf and Hearing individuals using a comprehensive dataset from Alabama Department of Mental Health spanning 2004-2024 (Deaf=4,547; Hearing=2,056,188). Chi-square analysis revealed significant proportional differences in diagnoses between the groups. Deaf individuals showed significantly higher proportions of psychotic (12.93% vs. 8.33% Hearing), mood (20.76% vs. 18.84% Hearing), and personality (0.58% vs. 0.43% Hearing) disorders. These findings suggest that increased access to specialized and competent mental health services for individuals who are Deaf, particularly following the increase of staffing patterns for the Office of Deaf Services in 2015,contributed to more accurate …

Intersecting Identities: The Leadership Journeys And Challenges Of Black Women Senior Leaders In Southern U.S. Predominantly White Institutions, Quizanae' Yvonne Cooper

Electronic Theses and Dissertations

This study looked at what Black women in high‑level leadership roles are experiencing at predominantly White institutions in Texas and Florida now that diversity, equity, and inclusion (DEI) policies have been rolled back. Using Black feminist theory and intersectionality as the foundation, the research focused on how race and gender shape their leadership, their decision‑making, and the ways they navigate their careers. Through in‑depth interviews with 10 Black women in executive positions, the study uses a narrative approach to understand their stories. Eight major themes emerged, and many participants explained that losing DEI initiatives created new obstacles, reduced support systems, …

Exploring The Lived Experiences Of Black Women In Undergraduate Stem Core Expansion Pathways, Lizzie L. Evans Martinez Alvarez

Electronic Theses and Dissertations

The use of social incongruence in the film Hidden Figures, which juxtaposed with STEM education as the most powerful in contrast with Black women as the least powerful, supported the argument for the specific problem of practice to examine the unmet need for socially and ethnically diverse student populations in U.S. STEM higher education and careers. The purpose of this hermeneutic phenomenological research study was to identify and analyze the lived experiences of Black women regarding barriers they perceive in the STEM educational and career decision-making processes, while exploring transformational pathways to STEM academic success. The study specifically analyzed …

Childhood Maltreatment And Deviations From Normative Brain Structure: A Mega-Analysis Of 3711 Individuals From The Enigma Major Depressive Disorder And Enigma Posttraumatic Stress Disorder Working Groups, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background. Childhood maltreatment (CM), encompassing abuse and neglect, is highly prevalent and associated with elevated risk for major depressive disorder (MDD), posttraumatic stress disorder (PTSD), and other related conditions. However, the extent to which neuroanatomical alterations in MDD and PTSD are attributable to CM is uncertain.

Methods. Here, we analyzed CM and whole-brain magnetic resonance imaging (MRI) data from 3711 participants in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) MDD and PTSD Working Groups (25 sites; mean age = 33.3 ± 13.0 years; 59.9% female). Normative modeling estimated deviation z scores for 14 subcortical volume, 68 cortical thickness …

As part of the Gastón Institute’s 2025 Latinos in Massachusetts series, we present here a profile of Puerto Ricans, the largest Latino population in the state. This report analyzes Public Use Microdata Sample (PUMS) data from the 2023 American Community Survey (ACS), conducted by the U.S. Census Bureau. Our descriptive analysis uses both household- and individual-level data to estimate population size and percentages and to compare Puerto Ricans to Other Latinos and Non-Latinos in the state.

Nature Versus Non-Natural Environments: Effects On Stress And Creativity, Amy J. Lim, Stephen M. Colarelli, Norman P. Li, Liqun Wei, Ming-Hong Tsai, Xiao-Xiao Liu, Mark Van Vugt

Research Collection School of Social Sciences

We examined the effects of nature-based environmental stimuli versus evolutionarily novel built or abstract art environments on creative production in three experiments. In Study 1 (N = 85), we compared people's creative performance in rooms set up to display either a natural or built landscape. In Study 2 (N = 62), participants completed creativity tasks after taking a walk in an urbanized city district or after a walk in a forested park. In Study 3 (N = 108), using a longitudinal field experiment taking place over three months, we examined the creative performance of factory employees by comparing their normal …

Using Large Language Models To Analyze Political Texts Through Natural Language Understanding, Kenneth Benoit, Scott De Marchi, Conor Laver, Michael Laver, Jinshuai Ma

Research Collection School of Social Sciences

Large language models (LLMs) offer scalable alternatives to human experts when analyzing political texts for meaning, using natural language understanding (NLU). Qualitative NLU methods relying on human experts are severely limited by cost and scalability. Statistical text-as-data methods are scalable but rely on strong and often unrealistic assumptions. We propose a systematic, scalable, and replicable method that can extend existing qualitative and quantitative approaches by using LLMs to interpret texts meaningfully rather than as mere data. Our ensemble means of LLM-generated estimates of party positions on six key issue dimensions correlate highly with equivalent mean ratings by country specialists. When …

When Stress Matters Most: Developmental Timing And Socio-Ecological Stressors Among Mexican-Origin Adolescents From Low-Income Immigrant Families, Ka I Ip, Wen Wen, Sujin Lee, Wei Xiang Sim, Su Yeong Kim

Research Collection School of Social Sciences

This study investigates the dynamic, time-varying associations between multiple socio-ecological stressors and internalizing symptoms among Mexican-origin youth from low-income immigrant families. Grounded in a socioecological framework and employing time-varying effect modeling (TVEM), we examine how stressors at the interpersonal, family, and neighborhood levels differentially influence anxiety and depressive symptoms across early adolescence (ages 11–13), middle adolescence (ages 14–17), and late adolescence/emerging adulthood (ages 18–20). Participants included 604 Mexican-origin adolescents (54% female) from low-income immigrant families, assessed across three waves spanning nine years. Five distinct stressors were identified: discrimination, foreigner stress, economic stress, language brokering stress, and neighborhood violence/non-safety. Results from …

Honing The Haptics Of The Heart: A New Defence Of The Perceptual Theory Of Emotion, Brandon Yip

Research Collection School of Social Sciences

According to the perceptual theory of emotion, emotions are evaluative perceptions. However, emotions involve us in a way that regular perception does not and this has led to two influential objections to the perceptual theory have emerged. According to the first objection, the perceptual theory is false because the phenomenology of emotion is the phenomenology of response. According to the second objection, the perceptual theory is false because emotions are susceptible to evaluations of rationality and reason-responsiveness. In this essay, I defend the perceptual theory by disarming these two objections. In response to the first objection, I suggest that emotional …

Success And Flourishing In Singapore: The Impact Of Laws And Policies On The Ethos And Character Of A People, Seow Hon Tan

Research Collection Yong Pung How School Of Law

According to virtue jurisprudence, good laws can be conducive to virtuous living; poor laws can contribute to character vices and entrench prejudices. This article focuses on what lies beyond the strict categorization of virtue and vice simpliciter—the ethos and mindset of a people. Using a case study of Singapore, this article examines how law, conceived of in the broadest sense as including policies chosen in a legal regime that leaves the concretization of policies to government bodies, can diminish the capacity and desire of individuals to live examined lives in pursuit of eudaimonia or flourishing. Insofar as living examined lives …

Knowledge Of Lifespan And Healthspan And Interest In Healthy Longevity Medicine Among The General Population In Singapore: The Singapore Healthy Longevity (Helo) Survey, Jonas John Posko Amalaraj, Belinda Wang, Anna Szucs, Louis Island, Laureen Yi-Ting Wang, Liz J. Horberg, Paul A. O'Keefe, Sonny Rosenthal, Yap-Seng Chong, Johannes J. Meij, Andrea B. Maier

Research Collection College of Integrative Studies

Given the growing global interest in Healthy Longevity Medicine (HLM), the field lacks understanding about public knowledge and interest, which are crucial for any public health intervention relying on HLM. This study presents findings from the Healthy Longevity (HELO) survey conducted in Singapore, assessing public knowledge regarding lifespan (number of years a person is alive), healthspan (number of years a person spends in good health), and interest in HLM. This nationwide cross-sectional survey, conducted between June and August 2024, involved 3034 participants. Main domains including questions on demographics, living arrangements, medical information, health behaviours, income and financial status were tested …

Systemic Functioning Of Puerto Rican Families With A Cancer Patient: A Qualitative-Oriented Mixed-Methods Study, Nicole M. Velez-Agosto

Psychological Science Faculty Publications

Systemic family interventions of Latino families with a cancer patient have been suggested as effective and necessary, but few studies have focused on evaluating systemic functioning to design culturally relevant interventions. The purpose of study was to assess systemic functioning in Puerto Rican families with a cancer patient using the Spanish translated version of the Family Genogram Interview (FGI) that measures Bowen’s four emotional processes in nuclear family and family of origin. Fifty-one Puerto Rican participants related to a cancer patient were interviewed. Results suggested an acceptable reliability for the FGI-Spanish and higher presence of symptoms in a spouse or …

Predictive Validity Of The Obsessive-Compulsive Inventory-4 And Florida Obsessive-Compulsive Inventory-Ii Severity Scale, Eric A. Storch, Ryan J. Mccarty, Maya Zehavi, Mahnoor Ahmad, Joseph D. Hovey, Isabella A. Cruz, Monica E. Ochoa, Nadeen Salhadar, Laura D. Seligman

Psychological Science Faculty Publications

Efficient and accurate screening tools are crucial for improving early identification and treatment outcomes among individuals with obsessive-compulsive disorder (OCD). This study evaluated the sensitivity and specificity of two OCD screening measures: the Obsessive-Compulsive Inventory-4 (OCI-4) and the Florida Obsessive-Compulsive Inventory-II (FOCI-II) severity scale. The measures were administered in a large transnational sample of Spanish speaking Latin American adults (N = 1696) with elevated obsessive-compulsive symptomatology. Participants completed diagnostic interviews (MINI and Y-BOCS) and self-report assessments across 23 sites in 11 countries. Both measures significantly distinguished OCD from non-OCD cases, with the FOCI-II demonstrating somewhat better predictive performance (AUC = …

User Experience (Ux) Meets Bureaucracy: Lessons From A Government Intranet Prototype, Scott Pelham, Jo Jung, Christopher Kueh

Research outputs 2022 to 2026

Implementing user experience (UX) methodologies within government settings is both possible and powerful – but fraught with systemic and cultural complexities. This report presents insights from the redesign of a government intranet for a prominent Australian emergency services organisation, using a human-centred design approach grounded in the Double Diamond framework. The research reveals a series of challenges: bureaucracy, opinion bias, overwhelming content volume with minimal organisational value, a governance paradox where design rules are desired but selectively applied, a disconnect in engagement from key stakeholders, and the impact of a design by committee approach. While these challenges were significant, they …

A Multi-Dimensional Analysis Of Household Food Waste In The Republic Of Ireland: Drivers, Patterns, And Impacts, Courage Yaw Krah

Doctoral

Despite growing research on consumer food waste, existing efforts have fallen short of achieving meaningful reductions. This challenge has primarily been attributed to the complex behavioural and demographic diversity within populations, reflected in varying practices of food acquisition, storage, preparation, and disposal. In addition, there is a limited understanding of the broader impacts of discarded food, particularly the environmental, economic, and nutritional losses. This results in an oversimplified view of HFW and leads to less effective intervention strategies. An integrated assessment that incorporates environmental, nutritional, and economic consequences can provide a more holistic representation of the problem and support the …

Unveiling The Experiences And Unmet Needs: A Qualitative Exploration Of Undocumented Immigrants Residing In Kansas, Carol Meza, Pedro Hernandez, Alicia Hawley-Bernardez, Christopher Bakke, Staci P. Wolfe

School of Social Work Faculty Publications

Undocumented immigrants in the United States (US) face numerous barriers to accessing services such as healthcare, employment, and social services due to their status. While media and immigration policy focus on the U.S. border states, significant populations of undocumented immigrants exist throughout the U.S. Using qualitative analysis of 20 personal accounts, this study examines their experiences in a Midwestern state through utilizing a strengths-perspective, which emphasizes individual and community assets. Recurrent experiential themes included problems with persistent racism, discrimination, housing, employment, health care, and mental health challenges, while undocumented immigrants demonstrate remarkable resilience. These findings suggest that they can benefit …

Cyborgs In The Chat: Technological Objects And Sociotechnical Interaction On Twitch.Tv, Yanro Judd C. Ferrer

Sociology & Anthropology Department Faculty Publications

This paper introduces the concept of Cyborgification, derived from the metaphor cyborg of Donna Haraway, to analyze how technological objects, such as emotes, bots, and third-party extensions, co-construct social life on Twitch.tv. Drawing on digital ethnography and interviews, it examines how viewers and streamers interact not just with each other but with the platform’s technical features in the production of humor, identity, and belonging. Through three scenes, a media-triggered emote ritual, a bot glitch turned joke, and an outsider’s exclusion due to missing plug-ins, this work shows how technological entanglement shapes participation. Cyborgification offers a sociotechnical lens that moves beyond …
