Influence Of Rapid Covid-19 Vaccine Development On Vaccine Hesitancy, Sonny Rosenthal, Christopher L. Cummings Dec 2021

Influence Of Rapid Covid-19 Vaccine Development On Vaccine Hesitancy, Sonny Rosenthal, Christopher L. Cummings

Research Collection College of Integrative Studies

Introduction: In the race to deploy vaccines to prevent COVID-19, there is a need to understand factors influencing vaccine hesitancy. Secondary risk theory is a useful framework to explain this, accounting for concerns about vaccine efficacy and safety. Methods: During the first week of July, 2020, participants (N = 216) evaluated one of three different hypothetical vaccine scenarios describing an FDA-approved vaccine becoming available “next week,” “in one year,” or “in two years.” Dependent variables were perceived vaccine efficacy, self-efficacy, perceived vaccine risk, and vaccination willingness. Covariates included vaccine conspiracy beliefs, science pessimism, media dependency, and perceived COVID-19 risk. Data …


Channel Integration Services In Online Healthcare Communities, Anqi Zhao, Qian Tang Dec 2021

Channel Integration Services In Online Healthcare Communities, Anqi Zhao, Qian Tang

Research Collection School Of Computing and Information Systems

In online healthcare communities, channel integration services have become the bridge between online and offline channels, enabling patients to easily migrate across channels. Different from pure online services, online-to-offline (On2Off) and offline-to-online (Off2On) channel integration services involve both channels. This study examines the interrelationships between pure online services and channel integration services. Using a panel dataset composed of data from an online healthcare community, we find that pure online services decrease patients’ demand for On2Off integration services but increase their use of Off2On integration services. Our findings suggest that providing healthcare services online can reduce online patients’ needs to visit …


Does Precise Case Disclosure Limit Precautionary Behavior? Evidence From Covid-19 In Singapore, Aljoscha Janssen, Matthew H. Shapiro Dec 2021

Does Precise Case Disclosure Limit Precautionary Behavior? Evidence From Covid-19 In Singapore, Aljoscha Janssen, Matthew H. Shapiro

Research Collection School Of Economics

Limiting the spread of contagious diseases can involve both government-managed and voluntary efforts. Governments have a number of policy options beyond direct intervention that can shape individuals’ responses to a pandemic and its associated costs. During its first wave of COVID-19 cases, Singapore was among a few countries that attempted to adjust behavior through the announcement of detailed case information. Singapore's Ministry of Health maintained and shared precise, daily information detailing local travel behavior and residences of COVID-19 cases. We use this policy along with device-level cellphone data to quantify how local and national COVID-19 case announcements trigger differential behavioral …


Economic Impact Of Targeted Government Responses To Covid-19: Evidence From The Large-Scale Cluster In Seoul, Kim, Kanghyock Koh, Jinwook Shin Dec 2021

Economic Impact Of Targeted Government Responses To Covid-19: Evidence From The Large-Scale Cluster In Seoul, Kim, Kanghyock Koh, Jinwook Shin

Research Collection School Of Economics

We estimate the economic impact of South Korea's targeted responses to the first large-scale COVID-19 cluster in Seoul. We find that foot traffic and retail sales decreased only within a 300 meter radius of the cluster and recovered to its pre-outbreak level after four weeks. The reductions appear to be driven by temporary business closures rather than the risk avoidance behavior of the citizens. Our results imply that less intense, but more targeted COVID-19 interventions, such as pin-pointed, temporary closures of businesses, can be a low-cost alternative after lifting strict social distancing measures.


The Pandemic As Political Opportunity: Jokowi’S Indonesia In The Time Of Covid-19, Charlotte Setijadi Dec 2021

The Pandemic As Political Opportunity: Jokowi’S Indonesia In The Time Of Covid-19, Charlotte Setijadi

Research Collection School of Social Sciences

In mid-2021, the Delta strain of the Covid-19 virus caused a second wave of transmissions and deaths in Indonesia at a scale much greater than what was seen in 2020. In this paper, I examine what the Indonesian government’s handling of the Covid crisis in 2021 reveals about the priorities of President Joko Widodo (Jokowi), as well as his political agenda and attitude towards the country’s democracy, as he strives to cement his legacy. I argue that, while devastating, the Covid-19 pandemic has given Jokowi the opportunity to push through long-planned economic and political reforms. Furthermore, I contend that, under …

Effect Of Renin-Angiotensin System Inhibitors On Acute Kidney Injury Among Patients Undergoing Cardiac Surgery: A Review And Meta-Analysis, Han Zhou, Jingui Xie, Zhichao Zheng, Oon Cheong Ooi, Haidong Luo

Research Collection Lee Kong Chian School Of Business

Acute kidney injury (AKI) is a frequent complication of cardiac surgery, which can lead to higher mortality and long-term renal function impairment. The effect of perioperative renin-angiotensin system inhibitors (RASi) therapy on AKI incidence in patients undergoing cardiac surgery remains controversial. We reviewed related studies in PubMed, Scopus, and Cochrane Library from inception to February 2020. Two randomized controlled trials and 21 cohort studies were included in the meta-analysis, involving 76,321 participants. The pooled odds ratio and 95% confidence interval were calculated using the DerSimonian and Laird random-effects model. The results showed no significant association between perioperative RASi therapy and …


Navigating The Pandemic As It Enters Its Second Year, Havovi Joshi Nov 2021

Navigating The Pandemic As It Enters Its Second Year, Havovi Joshi

Asian Management Insights

Many countries, enabled by the rapid vaccine rollout, experienced some moments of relief from the Covid-19 pandemic as they embarked on their long and winding transition toward normalcy. However, despite the Herculean effort expended, achieving herd immunity remains a distant goal for many due to the emergence of the highly transmissible and lethal Delta variant and the persistence of vaccine hesitancy. As such, the coronavirus continues to upend lives, businesses, and society, and the playbook for survival will still be a work-in-progress

The global COVID-19 pandemic is now in its second year, and we are fast approaching the third. The year 2021 has brought some hope that vaccination will lead to the end of the pandemic. But it has also brought a more infectious variant of COVID-19 and multiple waves of surging cases that show no immediate sign of disappearing. As the pandemic continues to impact global societies and economies, it is imperative that we study its impact to try and understand how it will affect us in both the short-term and long-term. While the longer-term impacts are still unknown, there is …

Cognitive Barriers To Covid-19 Vaccine Uptake Among Older Adults, Jonathan L. Chia, Andree Hartanto

Research Collection School of Social Sciences

The COVID-19 pandemic has resulted in tremendous loss of life. As of late-July 2021, there have been more than 191 million confirmed cases and over 4.1 million deaths recorded (1). Although most nations have developed some competency in COVID-19 containment (2–4), there are new challenges. The continual spread of COVID-19 has resulted in new variants (5–7). These new variants are posited to have a significantly higher transmissibility (8–10), with higher fatality rates (11, 12).


Shifting Employabilities: Skilling Migrants In The Nation Of Emigration, Yasmin Y. Ortiga Oct 2021

Shifting Employabilities: Skilling Migrants In The Nation Of Emigration, Yasmin Y. Ortiga

Research Collection School of Social Sciences

This paper examines how Philippine state agencies sustain its labour-exporting strategies by encouraging aspiring migrants to invest in their own training and education, taking on the responsibility of turning themselves into desirable workers for employers overseas. Based on a document analysis of newspaper articles and Philippine government reports, this paper uses the case of Philippine nursing education to show how the Philippine state alters these discourses of skill when overseas opportunities decline, channelling aspiring migrants sideways to other sectors of the labour market. Discourses of employability justified these career detours to aspiring migrants by assuring them that such experiences will …

Constrained Contrastive Distribution Learning For Unsupervised Anomaly Detection And Localisation In Medical Images, Yu Tian, Guansong Pang, Fengbei Liu, Yuanhong Chen, Seon Ho Shin, Johan W. Verjans, Rajvinder Singh Oct 2021

Constrained Contrastive Distribution Learning For Unsupervised Anomaly Detection And Localisation In Medical Images, Yu Tian, Guansong Pang, Fengbei Liu, Yuanhong Chen, Seon Ho Shin, Johan W. Verjans, Rajvinder Singh

Research Collection School Of Computing and Information Systems

Unsupervised anomaly detection (UAD) learns one-class classifiers exclusively with normal (i.e., healthy) images to detect any abnormal (i.e., unhealthy) samples that do not conform to the expected normal patterns. UAD has two main advantages over its fully supervised counterpart. Firstly, it is able to directly leverage large datasets available from health screening programs that contain mostly normal image samples, avoiding the costly manual labelling of abnormal samples and the subsequent issues involved in training with extremely class-imbalanced data. Further, UAD approaches can potentially detect and localise any type of lesions that deviate from the normal patterns. One significant challenge faced …

We build on recent examinations questioning the quality of online information about probiotic products by studying the themes of content, detecting virtual communities and identifying key influencers in social media using data science techniques. We conducted topic modelling (n = 36,715 tweets) and longitudinal social network analysis (n = 17,834 tweets) of probiotic chatter on Twitter from 2009–17. We used Latent Dirichlet Allocation (LDA) to build the topic models and network analysis tool Gephi for building yearly graphs. We identified the top 10 topics of probiotics-related communication on Twitter and a constant rise in communication activity. However the number of …


Prediction Of Synthetic Lethal Interactions In Human Cancers Using Multi-View Graph Auto-Encoder, Zhifeng Hao, Di Wu, Yuan Fang, Min Wu, Ruichu Cai, Xiaoli Li Oct 2021

Prediction Of Synthetic Lethal Interactions In Human Cancers Using Multi-View Graph Auto-Encoder, Zhifeng Hao, Di Wu, Yuan Fang, Min Wu, Ruichu Cai, Xiaoli Li

Research Collection School Of Computing and Information Systems

Synthetic lethality (SL) is a very important concept for the development of targeted anticancer drugs. However, experimental methods for SL detection often suffer from various issues like high cost and low consistency across cell lines. Hence, computational methods for predicting novel SLs have recently emerged as complements for wet-lab experiments. In addition, SL data can be represented as a graph where nodes are genes and edges are the SL interactions. It is thus motivated to design advanced graph-based machine learning algorithms for SL prediction. In this paper, we propose a novel SL prediction method using Multi-view Graph Auto-Encoder (SLMGAE). We …

Precision Public Health Campaign: Delivering Persuasive Messages To Relevant Segments Through Targeted Advertisements On Social Media, Jisun An, Haewoon Kwak, Hanya M. Qureshi, Ingmar Weber

Research Collection School Of Computing and Information Systems

Although established marketing techniques have been applied to design more effective health campaigns, more often than not, the same message is broadcasted to large populations, irrespective of unique characteristics. As individual digital device use has increased, so have individual digital footprints, creating potential opportunities for targeted digital health interventions. We propose a novel precision public health campaign framework to structure and standardize the process of designing and delivering tailored health messages to target particular population segments using social media–targeted advertising tools. Our framework consists of five stages: defining a campaign goal, priority audience, and evaluation metrics; splitting the target audience …

Psychology And The Threat Of Contagion: Feeling Vulnerable To A Disease Moderates The Link Between Xenophobic Thoughts And Support For Ingroup-Protective Actions, Heejung S. Kim, Kimin Eom, Roxie Chuang, David K. Sherman

Research Collection School of Social Sciences

The widespread threat of contagious disease disrupts not only everyday life but also psychological experience. Building on findings regarding xenophobic responses to contagious diseases, this research investigates how perceived vulnerability to a disease moderates the psychological link between people’s xenophobic thoughts and support for ingroup-protective actions. Three datasets collected during the time of Ebola (N = 867) and COVID-19 (Ns = 992 and 926) measured perceived disease risk, group-serving biases (i.e., xenophobic thoughts), and support for restrictive travel policies (i.e., ingroup-protective actions). Using correlational and quasi-experimental analyses, results indicated that for people who perceive greater disease risk, the association between …

A Multi-Country Test Of Brief Reappraisal Interventions On Emotions During The Covid-19 Pandemic, Ka Wang, Amit Goldenberg, Charles Dorison, Et Al., Nadyanna Mohamed Majeed, Andree Hartanto

Research Collection School of Social Sciences

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across …

When A Pandemic Disrupts The Export Of People, Yasmin Y. Ortiga, Karen Anne S. Liao

Research Collection School of Social Sciences

Yasmin Ortiga and Karen Anne S. Liao conducted research supported by the SSRC on the dramatic disruptions that Filipino labor migrants experienced as a result of the Covid-19 pandemic, and the support (or lack thereof) of their plight by the Filipino state. Arguing that labor as well as commodity supply chains have been thrown in upheaval, the authors describe the limits of the Philippines’ labor export strategy. In particular, they focus on two sets of labor migrants—nurses unable to take jobs abroad, and repatriated cruise ship workers—for whom dignified work at home was unavailable. Ortiga and Liao conclude that treating …

Media In A Time Of Crisis: Newspaper Coverage Of Covid-19 In East Asia;, Colm A. Fox

Research Collection School of Social Sciences

How have newspapers covered Covid-19 in Asia? To answer this question, I studied East Asian English-language newspapers published between January and July 2020. First, I measured the level of news media attention on Covid-19 among all reports. Second, I analyzed the tone and content of 330 editorials. I divided the analysis into two time periods: the initial crisis breakout period, when the number of infections was rising or high, and the crisis abatement period, when new infections declined to manageable levels. Findings show that although newspapers were slow to begin addressing the pandemic, their early editorials carried an alarming tone, …

COVID-19 has reshaped our lives, the global economy, and the geopolitical landscape in unimaginable ways. Socio-economic disruptions are keenly felt across every sector in every country and irreversible damage has been done to our collective health and livelihood opportunities. From a health crisis, the pandemic has insidiously unfolded into a human one - where efforts taken to contain the virus have resulted in the targeting and/or neglect of vulnerable populations, the exacerbation of structural inequalities, and the pushback against fundamental rights and freedoms. The prolonging of this health crisis has also accentuated the need for better governance as questions of …


Tracetogether And Safeentry Were Never Foolproof In Averting Recent Fishery Port And Ktv Clusters, Mark Findlay Jul 2021

Tracetogether And Safeentry Were Never Foolproof In Averting Recent Fishery Port And Ktv Clusters, Mark Findlay

Research Collection Yong Pung How School Of Law

Don’t blame the technology. COVID-19 control technology depends on the cooperation of people to be fully effective, says SMU Professor Mark Findlay. Singapore has one of the best subscribed COVID-19 tracing, tracking and safe entry apps worldwide. Then how is it that we are back to Phase 2 (Heightened Alert)? It would be tempting but wrong to blame the technology as being insufficiently intrusive or robust. A look at the recent outbreak suggests we should avoid an over-reliance on tech solutions when incompatible human behaviours are at work.

Special Report On Covid-19 Vaccination Trends Among Older Adults In Singapore, Micah Tan, Paulin T. Straughan, Wensi Lim, Grace Cheong

ROSA Research Briefs

This report examines trends in vaccination among older adults in Singapore to better understand why segments of older adults continue to resist vaccination against COVID-19. We find that individuals who were most likely to still be waiting to vaccinate or to not want to be vaccinated as of June 2021; are relatively older (aged 71-75), are of lower socioeconomic status (lower education levels and living in 1-3 room HDB flats), were the least likely to rely on Newspapers and Government Sources as sources of information for COVID-19 related news in November 2020, were least trusting of all sources of information, …

Research Collection School Of Computing and Information Systems

Disease-gene association through Genome-wide association study (GWAS) is an arduous task for researchers. Investigating single nucleotide polymorphisms (SNPs) that correlate with specific diseases needs statistical analysis of associations. Considering the huge number of possible mutations, in addition to its high cost, another important drawback of GWAS analysis is the large number of false-positives. Thus, researchers search for more evidence to cross-check their results through different sources. To provide the researchers with alternative and complementary low-cost disease-gene association evidence, computational approaches come into play. Since molecular networks are able to capture complex interplay among molecules in diseases, they become one of …


Religion, Social Connectedness, And Xenophobic Responses To Ebola, Roxie Chuang, Kimin Eom, Heejung S. Kim Jul 2021

Religion, Social Connectedness, And Xenophobic Responses To Ebola, Roxie Chuang, Kimin Eom, Heejung S. Kim

Research Collection School of Social Sciences

This study examined the role of religion in xenophobic responses to the threat of Ebola. Religious communities often offer members strong social ties and social support, which may help members cope with psychological and physical threat, including global threats like Ebola. Our analysis of a nationally representative sample in the U.S. (N = 1,000) found that overall, the more vulnerable to Ebola people felt, the more they exhibited xenophobic responses, but this relationship was moderated by importance of religion. Those who perceived religion as more important in their lives exhibited weaker xenophobic reactions than those who perceived religion as less …

Information Avoidance And Medical Screening: A Field Experiment In China, Yufeng Li, Juanjuan Meng, Changcheng Song, Kai Zheng

Research Collection Lee Kong Chian School Of Business

Will individuals, especially high-risk individuals, avoid a disease test because of information avoidance? We conduct a field experiment to investigate this issue. We vary the price of a diabetes test (price experiment) and offer both a diabetes test and a cancer test (disease experiment) after eliciting participants’ subjective beliefs about their disease risk. We find evidence that, first, some people avoid the test even when there is neither a monetary nor a transaction cost, and second, both low- and high-risk individuals select out of the test as the price increases. We explain our findings using three classes of models of …
