Expanding Public Access to Understanding Data
Interactive dashboards have become central tools for visualizing policy-relevant data, but they remain limited by rigid structures and technical complexity. Recent advances in large language model (LLM)-powered conversational artificial intelligence (AI) offer a way to address these challenges, as LLMs can interpret unstructured natural language inputs and translate them into structured functions. This proof-of-concept study introduces a generati…
The role of peer social support in marginalization and social anxiety among adolescents in Burmese American refugee communities
Purpose This study investigates how acculturation strategies (separation, marginalization, assimilation and integration) relate to social anxiety among adolescents in Burmese American refugee communities. It also examines whether peer support moderates these relationships. This study aims to identify social and cultural factors that contribute to or protect against anxiety in this underserved population, informing targeted, culturally responsive …
Covid-19 Discrimination and Social Anxiety in Burmese Refugees
Amidst the COVID-19 pandemic, discrimination against Asian refugees surged. Discrimination is associated with higher social anxiety, which may be mediated by acculturation, yet the negative effects could be buffered by social support. This study examined whether COVID-19 anti-Asian discrimination would predict greater social anxiety in Burmese refugees through acculturation and whether social support moderated these effects. A moderated mediation…
Digital Twins
Digital twin (DT) emerges as a frontier for integrating research, development, innovation, and problem‐solving through digital technologies. DT enables analyses and solutions to real‐world problems by leveraging advanced observation data from sources of in situ (monitoring stations), citizen sensing, and satellites. DT seeks to best replicate real‐world problems and conduct “what‐if” analyses for optimum solutions. Data fusion technologies are em…
Development and validation of nomogram for predicting cognitive frailty with multimorbidity
Objectives: This study aims to develop and validate a nomogram for cognitive frailty in older patients with multimorbidity. Methods: From April 2022 to December 1, 2024, a total of 711 older patients participated in the study. The study was conducted at a tertiary hospitals in Changsha, Hunan Province, China. We employed LASSO regression to identify initial variables associated with risk factors for older adults with multimorbidity and subsequent…
Generative AI for Geospatial Analysis
This study investigates the potential of fine-tuned large language models (LLMs) to enhance geospatial intelligence by translating natural language queries into executable Python code. Traditional GIS workflows, while effective, often lack usability and scalability for non-technical users. LLMs offer a new approach by enabling conversational interaction with spatial data. We evaluate OpenAI’s GPT-4o-mini model in two forms: an “As-Is” baseline an…

Rural‐Urban Differences in the Determinants of Subjective Well‐Being Among X/Twitter Users in the United States
Twitter Sentiment Geographical Index (TSGI) has been proposed to complement traditional surveys to measure subjective well‐being (SWB) at the US county level. Our study aims to investigate determinants of TSGI‐measured SWB in rural and urban US counties. Using the Classification and Regression Tree, we identified phenotypes or county‐level characteristics associated with high SWB. Counties with newer homes were the top characteristic of high SWB …
Paid caregivers' experiences of falls prevention and care in China's senior care facilities
Background: In China, as population aging accelerates, senior care facilities have gradually become a mainstream option. According to the World Health Organization (WHO), the annual rate of falls has increased from 30 to 50% in senior care facilities. A study found that older adults who live in senior care facilities are three times more likely to fall than those who live in the community. The quality of care is highly related to the occurrence o…
Older people’s attitudes towards emerging technologies
Public attitudes towards technology have been studied extensively for decades, but older people were not largely involved in early studies. In recent years, with the trend of digitalisation and the rapid growth of the older population around the world, the attitudes of older people towards emerging technologies have attracted the attention of researchers. This article is a systematic review of 83 relevant studies, to summarise the factors that im…
The times, they are a-changin’
INTRODUCTION: Widespread problems of psychological distress have been observed in many countries following the outbreak of COVID-19, including Australia. What is lacking from current scholarship is a national-scale assessment that tracks the shifts in mental health during the pandemic timeline and across geographic contexts. METHODS: Drawing on 244 406 geotagged tweets in Australia from 1 January 2020 to 31 May 2021, we employed machine learning …

Covid-19 Infection and Contact Tracing Among Refugees in the United States, 2020–2021
Urban-regional disparities in mental health signals in Australia during the Covid-19 pandemic
This study establishes a novel empirical framework using machine learning techniques to measure the urban-regional disparity of the public’s mental health signals in Australia during the pandemic, and to examine the interrelationships amongst mental health, demographic and socioeconomic profiles of neighbourhoods, health risks and healthcare access. Our results show that the public’s mental health signals in capital cities were better than those …
The promise of excess mobility analysis
Human mobility studies have become increasingly important and diverse in the past decade with the support of social media big data that enables human mobility to be measured in a harmonized and rapid manner. However, what is less explored in the current scholarship is episodic mobility as a special type of human mobility defined as the abnormal mobility triggered by episodic events excess to the normal range of mobility at large. Drawing on a lar…
Social support and resilience among Burmese adolescent refugees
Culturally-Appropriate Orientation Increases the Effectiveness of Mental Health First Aid Training for Bhutanese Refugees
A Theory of Auctions with Endogenous Valuations
We derive the symmetric, revenue-maximizing allocation of several units among agents who take costly actions that influence their values. The problem is equivalent to a reduced-form model where agents have nonexpected utility. The uniform-price auction and the discriminatory pay-your-bid auction with reserve prices that react to both demand and supply constitute symmetric, optimal mechanisms. We also identify a condition under which the overall o…
Migration and Health
Demographers and other social scientists have investigated a wide range of impacts that migration has upon sending and receiving communities, families, and the migrants themselves, but there has been little systematic investigation of migration's impacts on health. In this entry we explore the potential pathways through which migration can affect health outcomes; discuss four major dimensions of health for which migration's impacts have been inve…
