Life Satisfaction Changes And Adaptation In The Covid-19 Pandemic: Evidence From Singapore, Terence C. Cheng, Kim, Kanghyock Koh

Research Collection School Of Economics

We provide novel evidence on how COVID-19 affected overall life satisfaction using a monthly longitudinal survey of middle-aged and older Singaporeans. We study how the subjective well-being of individuals evolves over the course of 18 months including the outbreak of the pandemic, the implementation of the lockdown and the spike of cases due to the delta variant in a country where COVID-19 is controlled in a sustained manner. Using an event-study design framework, we find large declines in overall life satisfaction in the lead-up to and following the lockdown. Fifteen months after the outbreak of the pandemic, and 13 months …

Can Big Data Cure Risk Selection In Healthcare Capitation Program? A Game Theoretical Analysis, Zhaowei She, Turgay Ayer, Daniel Montanera Nov 2022

Can Big Data Cure Risk Selection In Healthcare Capitation Program? A Game Theoretical Analysis, Zhaowei She, Turgay Ayer, Daniel Montanera

Research Collection Lee Kong Chian School Of Business

Problem definition: This paper analyzes a market design problem in Medicare Advantage (MA), the largest risk-adjusted capitation payment program in the U.S. healthcare market. Evidence exists that the current MA capitation payment program unintentionally incentivizes health plans to cherry pick profitable patient types, which is referred to as “risk selection”. However, the root causes of the risk selection are not comprehensively understood, which we study in this paper. Academic / Practical Relevance: The existing literature primarily attributes the observed risk selection in MA market to data limitations and low explanatory power (e.g. low R2) of the current risk adjustment design. …

Research Collection School Of Computing and Information Systems

This article explains how two AI systems have been incorporated into the everyday operations of two Singapore public healthcare nation-wide screening programs. The first example is embedded within the setting of a national level population health screening program for diabetes related eye diseases, targeting the rapidly increasing number of adults in the country with diabetes. In the second example, the AI assisted screening is done shortly after a person is admitted to one of the public hospitals to identify which inpatients—especially which elderly patients with complex conditions—have a high risk of being readmitted as an inpatient multiple times in the …


Of Landlords And Tenants: Property In The Midst Of A Pandemic, Seng Wei, Edward Ti Oct 2022

Of Landlords And Tenants: Property In The Midst Of A Pandemic, Seng Wei, Edward Ti

Research Collection Yong Pung How School Of Law

Described as the crisis of our generation, the coronavirus pandemic has had a profound effect on consumption behaviour, in turn devastating businesses globally. Marking a departure from the sanctity of contract and causing perceived incursions to accrued legal rights, the Coronavirus Act 2020 and related legislation provide business tenancies protection, among others, against forfeiture for non-payment of rent. While this regulation of commercial tenancies appears to be justified on the basis of pragmatic utility, I suggest that Honoré’s incident of ownership prohibiting harmful use also allows for these emergency laws to be vindicated from a property perspective. This provides an …

Analyzing The Impact Of Covid-19 Control Policies On Campus Occupancy And Mobility Via Wifi Sensing, Camellia Zakaria, Amee Trivedi, Emmanuel Cecchet, Michael Chee, Prashant Shenoy, Rajesh Krishna Balan

Research Collection School Of Computing and Information Systems

Mobile sensing has played a key role in providing digital solutions to aid with COVID-19 containment policies, primarily to automate contact tracing and social distancing measures. As more and more countries reopen from lockdowns, there remains a pressing need to minimize crowd movements and interactions, particularly in enclosed spaces. Many COVID-19 technology solutions leverage positioning systems, generally using Bluetooth and GPS, and can theoretically be adapted to monitor safety compliance within dedicated environments. However, they may not be the ideal modalities for indoor positioning. This article conjectures that analyzing user occupancy and mobility via deployed WiFi infrastructure can help institutions …

Contrastive Transformer-Based Multiple Instance Learning For Weakly Supervised Polyp Frame Detection, Tian Yu, Guansong Pang, Fengbei Liu, Yuyuan Liu, Chong Wang, Yuanhong Chen, Johan Verjans, Gustavo Carneiro

Research Collection School Of Computing and Information Systems

Current polyp detection methods from colonoscopy videos use exclusively normal (i.e., healthy) training images, which i) ignore the importance of temporal information in consecutive video frames, and ii) lack knowledge about the polyps. Consequently, they often have high detection errors, especially on challenging polyp cases (e.g., small, flat, or partially visible polyps). In this work, we formulate polyp detection as a weakly-supervised anomaly detection task that uses video-level labelled training data to detect frame-level polyps. In particular, we propose a novel convolutional transformer-based multiple instance learning method designed to identify abnormal frames (i.e., frames with polyps) from anomalous videos (i.e., …

The Intergenerational Mortality Tradeoff Of Covid-19 Lockdown Policies, Lin Ma, Gil Shapira, Damien De Walque, Quy-Toan Do, Jed Friedman, Andrei A. Levchenko

Research Collection School Of Economics

In lower-income countries, the economic contractions that accompany lockdowns to contain COVID-19 transmission can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, we build a macro-susceptible-infected-recovered model that features heterogeneous agents and a country-group-specific relationship between economic downturns and child mortality and calibrate it to data for 85 countries across all income levels. We find that in some low-income countries, a lockdown can produce net increases in mortality. The optimal lockdown that maximizes the present value of aggregate social welfare is shorter and milder in poorer countries than in rich ones.

How Does Parents' Social Support Impact Children's Health Practice? Examining A Mediating Role Of Health Knowledge, Paulin Tay Straughan, Chengwei Xu

Research Collection School of Social Sciences

Background: Many existing studies have found that social support and health knowledge positively affect an individual's health status. However, it is still unclear how parents’ social support and health knowledge influence their children’s obesity. The present study hypothesizes that parents’ health knowledge has a mediating effect on the relationship between social support and children’s health practice regarding weight management. Methods: To test the hypothesis, we conducted a questionnaire survey in Singapore and collected a nationally representative sample of 1488 household responses. Structural equation modeling (SEM) via Stata was used to examine the indirect effects of parents’ social support on children’s …

Clocking Out: Nurses Refusing To Work In A Time Of Pandemic, Yasmin Y. Ortiga, Michael Joseph S. Dino, Romeo Luis A. Macabasag

Research Collection School of Social Sciences

Social science research has long critiqued how professional ideals of public service can ignore chronic problems within the healthcare industry, placing unfair burden on the "heroism" of individual workers. Yet, fewer studies investigate how healthcare professionals actively negotiate such demands for service, amidst increasing workplace pressures and risks. This paper studies Filipino nurses' response to a government policy that banned them from working overseas in order to channel their labor to local hospitals during the COVID-19 pandemic. Based on 51 in-depth interviews, we argue that nurses' willingness to serve in the Philippines' COVID-19 hospitals hinged on the point at which …
