Estimating E-Scooter Traffic Flow Using Big Data To Support Planning For Micromobility, Feng Chen, Junfeng Jiao, Haofeng Wang

Research Collection College of Integrative Studies

Dockless e-scooter sharing, as a new shared micromobility service, has quickly gained popularity in recent years. In this paper, we present a practical approach to estimating e-scooter flow patterns without knowing the actual routes taken by the e-scooter riders. Our method takes advantage of a huge open dataset that contains the origins and destinations of millions of trips. We show that our models can help cities better support the emerging shared micromobility service. The additional information generated in the modeling process can also be useful for a more refined analysis of e-scooter trips.

Beem: Data-Driven Building Energy Benchmarking For Singapore, Pandarasamy Arjunan, Kameshwar Poolla, Clayton Miller

Research Collection College of Integrative Studies

Building energy use benchmarking is the process of measuring the energy performance of buildings relative to their peer group for creating awareness and identifying energy-saving opportunities. In this paper, we present the design and implementation of BEEM, a data-driven energy use benchmarking system for buildings in Singapore. The peer groups for comparison are established using a public energy disclosure data set. We use an ensemble tree algorithm for accurately modeling building energy use and for identifying the most influential factors. Our models reduce the prediction error from 24.39% to 6.04%, on average, when compared to the baseline linear regression models, …

Testing Theoretical Assumptions Underlying The Relation Between Anxiety, Mind Wandering, And Task-Switching: A Diffusion Model Analysis, Andree Hartanto, Hwajin Yang

Research Collection School of Social Sciences

Despite the well-documented negative effects of anxiety on task-switching (switch costs), few studies have directly tested major theoretical assumptions about (a) the specific processing component of task-switching that is impaired by anxiety, (b) anxious individuals’ strategies during task-switching, and (c) the mediating role of mind wandering in the relation between anxiety and task-switching. We addressed these issues using a stochastic diffusion model analysis and novel thought-probe technique in the task-switching paradigm. Our results suggest that the locus of impaired switch costs under state anxiety lies in the efficiency of task-set reconfiguration and not in proactive interference processing. Moreover, state anxiety …

Investor Sentiment And Paradigm Shifts In Equity Premium Forecasting, Liya Chu, Kai Li, Tony Xue-Zhong He, Jun Tu

Research Collection Lee Kong Chian School Of Business

This study investigates the impact of investor sentiment on excess equity return forecasting. A high (low) investor sentiment may weaken the connection between fundamental economic (behavioral-based non-fundamental) predictors and market returns. We find that although fundamental variables can be strong predictors when sentiment is low, they tend to lose their predictive power when investor sentiment is high. Non-fundamental predictors perform well during high-sentiment periods while their predictive ability deteriorates when investor sentiment is low. These paradigm shifts in equity return forecasting provide a key to understanding and resolving the lack of predictive power for both fundamental and non-fundamental variables debated …

Do Underwriters Short-Change Corporations Issuing Bonds?, Choo Yong, Jeremy Goh, Lisa Yang

Research Collection Lee Kong Chian School Of Business

We confirm prior evidence that bonds on average are offered at prices below their immediate post-offer secondary market prices. However, in cases where banks lead-manage their own bond offerings the underpricing is significantly less as compared to other non-self-marketed offerings. These findings are robust across various matched samples and selection models. Our results suggest that the bond offering process is characterized by substantive agency conflicts between shareholders of corporations (issuers) and underwriters.

Unconventional Monetary Policy And Disaster Risk: Evidence From The Subprime And Covid–19 Crises, Gustavo S. Cortes, George P. Gao, Felipe B. G. Silva, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

We compare the interventions conducted by the Federal Reserve in response to the subprime and COVID–19 crises with respect to their effectiveness in reducing disaster risk. Using model-free measures of disaster risk derived from daily options data, we document that interventions in response to both crises reduced tail risks in domestic equity markets. The spillover effects of the two crises have been markedly dissimilar. While subprime interventions are generally characterized by negative spillovers to international equity markets, policy responses to the COVID–19 crisis are generally associated with positive spillovers. We interpret these results as consistent with the different degrees of …

Making Universal Digital Access Universal: Lessons From Covid-19 In Singapore, Irene Y. H. Ng, Sun Sun Lim, Natalie Pang

Research Collection College of Integrative Studies

Digital resources—which include devices, internet connection and digital literacy—have become basic needs. Thus with the global COVID-19 pandemic having accelerated digitalization, the urgency for universal digital inclusion has hastened. Otherwise, digital inequality will lead to social inequality and impede social mobility. Using Singapore as a case study, this article applies the insights learned from a participatory action research to recommend a policy framework for universal digital access, with practical humanistic steps towards full digital inclusion. Singapore is a digitally advanced nation with almost universal digital availability, yet when COVID-19 forced rapid digital adoption, gaps in access by vulnerable groups such …

A Survey On Modern Deep Neural Network For Traffic Prediction: Trends, Methods And Challenges, David Alexander Tedjopumomo, Zhifeng Bao, Baihua Zheng, Farhana Murtaza Choudhury, Kai Qin

Research Collection School Of Computing and Information Systems

In this modern era, traffic congestion has become a major source of negative economic and environmental impact for urban areas worldwide. One of the most efficient ways to mitigate traffic congestion is through future traffic prediction. The field of traffic prediction has evolved greatly ever since its inception in the late 70s. Earlier studies mainly use classical statistical models such as ARIMA and its variants. Then, researchers started to focus on machine learning models due to their power and flexibility. As theoretical and technological advances emerge, we enter the era of deep neural network, which gained popularity due to its …

Regional Mapping: Digital Provisions Play A Key Role In Asia Pacific Agreements, Henry S. Gao

Research Collection Yong Pung How School Of Law

This mapping covers all free trade agreements (FTAs) with chapters on e-commerce or digital trade since 2000 by the main players in the region-China, South Korea, Japan, India, Australia, New Zealand, Singapore, Vietnam and Malaysia.

Whither Privacy Protection In The Law Of Nuisance, Cheng Lim Saw, Aaron Yoong

Research Collection Yong Pung How School Of Law

Privacy-related concerns often feature in disputes involving the tort of private nuisance. Despite the growing importance ascribed to the protection of an individual’s privacy in the modern world, English law has tended to shy away from allowing such concerns to influence the thinking behind the more traditional areas of law (like nuisance). This article examines and questions the various notions that underpin this English approach. Using the recent decisions of Giles Duncan Fearn v The Board of Trustees of the Tate Gallery [2019] EWHC 246 (Ch) and Giles Fearn v The Board of Trustees of the Tate Gallery [2020] EWCA …

Executive Function Moderates The Effect Of Reappraisal On Life Satisfaction: A Latent Variable Analysis, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

Emotion regulation strategies, such as reappraisal and suppression, have been shown to dissimilarly affect life satisfaction. Specifically, reappraisal is linked to higher life satisfaction, while suppression is associated with lower life satisfaction. Less is known, however, about the potential moderators of these established relations. Given that reappraisal and suppression are contingent, in part, on executive function (EF), which comprises a group of adaptive, goal-orientated control processes (i.e., inhibitory control, working memory, and shifting), we explored whether different components of EF could moderate the impact of reappraisal and suppression on life satisfaction. Using latent moderated structural equation analyses, we found that …

Borderline Personality Traits And Romantic Relationship Dissolution, Kenneth Tan, Samantha H. Ingram, Laura Anne Lau, Susan South

Research Collection School of Social Sciences

Many studies have found that borderline personality disorder (BPD) is associated with romantic relationship instability, with relationship dissolution being a recurring theme. Scant research, however, has examined the dissolution strategies and post-breakup outcomes for individuals with elevated levels of borderline traits. Findings from two studies revealed that there was an association between BPD criteria and tendency to employ less adaptive dissolution strategies when terminating a relationship. Furthermore, elevated levels of BPD traits were associated with less self-concept clarity and more unwanted pursuit of ex-partners. These findings both provide insight into how individuals with BPD traits experience relationship dissolution and suggest …

Perceptions Of Emotional Functionality: Similarities And Differences Among Dignity, Face, And Honor Cultures, Maitner A.T., Decoster J., Andersson P.A., Eriksson K., Sherbaji S., Giner-Sorolla R., Mackie D.M., Aveyard M., Claypool H.M., Crisp R.J., Gritskov V., Habjan K., Andree Hartanto, Kiyonari T., Kuzminska A.O., Manesi Z., Molho C., Munasinghe A., Peperkoorn L.S., Shiramizu V.

Research Collection School of Social Sciences

Emotions are linked to wide sets of action tendencies, and it can be difficult to predict which specific action tendency will be motivated or indulged in response to individual experiences of emotion. Building on a functional perspective of emotion, we investigate whether anger and shame connect to different behavioral intentions in dignity, face, and honor cultures. Using simple animations that showed perpetrators taking resources from victims, we conducted two studies across eleven countries investigating the extent to which participants expected victims to feel anger and shame, how they thought victims should respond to such violations, and how expectations of emotions …

Socializing Targets Of Older Adults’ Sns Use: Social Strain Mediates The Relations Between Older Adults’ Sns Use With Friends And Well-Being Outcomes, Yue Qi Germaine Tng, Hwajin Yang

Research Collection School of Social Sciences

Studies have yielded mixed findings regarding the relation between older adults’ social networking site (SNS) use and well-being. Drawing on socioemotional selectivity theory, we sought to examine whether older adults’ SNS use with different socializing targets (i.e., family vs friends) would differentially predict global, social, and mental well-being outcomes indexed by life satisfaction, loneliness, and depressive symptoms, respectively. Furthermore, we examined whether social support and social strain would mediate, in parallel, the relations between SNS use and well-being outcomes. We recruited healthy, community-dwelling older adults (ages 60–93 years, N = 69). Using the PROCESS macro, we found that SNS use …

Geopolitics And Ballpark Estimates, Thomas Lam, David Fernandez

Sim Kee Boon Institute for Financial Economics

Most economist commenced 2022 with 3 key assumptions on the global economy:

1) Some policy normalisation and reversal, though cautious and uneven, are likely to occur in economies with above-average growth and inflation;

2) The Covid-19 infection wave, while presumably asymmetric and recurrent across countries, appears to have less of an imprint on cyclical activity on balance;

3) The lingering supply disruptions resulting from the pandemic, albeit still intense and widespread, should be easing gradually.

Note To Self: How I Can Be A Better Reviewer?, Reddi Kotha

Research Collection Lee Kong Chian School of Business

In this article I review some of the common errors I have made as a reviewer and suggest ways to avoid them.The progress of science depends on reviewers as much as it depends upon researchers developing new science. Reviewers provide impartial, anonymous, and expert advice to researchers, and they screen which research gets published in scientific journals. When the review process works well, it acts as an effective filter and enables dissemination of high-quality and rigorous scientific work. As so much of scientific progress depends upon review, it is surprising that reviewers learn this science by doing. Of course, there …

Reflection On Wise Cities And Ai In Community: Sustainable Life Spaces And Kampung Storytelling, Mark Findlay, Li Min Ong

Centre for Commercial Law in Asia

This short paper is a reflection following our presentation made at the ASEAN Law Research Network’s conference on Sustainable Development and Commerce in ASEAN Cities. We had wanted to introduce our thinking, given the strong interest in developing smart cities in the region. We want to emphasise the importance of multidisciplinary approaches in the sustainable development of cities, particularly the voice of social scientists which tends to get left out in discussions over technology. In the race towards “smart” urbanisation, there is a real risk that history and culture – things that give a city “life” – could get decimated …

Toward An Environmentally Sustainable City In The Light Of Industrial Revolution 4.0: A Case Study Of Ho Chi Minh City, Tran Viet Dung

Centre for Commercial Law in Asia

Like other large cities in ASEAN, Vietnamese cities have been facing serious urban environment problems such as air pollution, land degradation, weak water drainage and lack of green spaces. These problems are caused by unsustainable patterns of development. City governments have failed to coordinate and integrate city planning consistently. Trends show that governments prefer to take short-term economic profit rather than focus on environmental protection.

Legal Challenges And Opportunities For Peer-To-Peer Electricity Trading In Thailand, Piti Eiamchamroonlarp

Centre for Commercial Law in Asia

Electricity is a critical resource for a country as it powers devices and enables modern living with digital transactions, crypto mining, deployment of electric vehicles (EV) etc. Given these emerging activities, electricity demand is forecasted to keep rising. The peak electricity load in Thailand for 2018, 29,969 MW, will likely increase to 53,997 MW by 2037. However, Thailand, as a party to the United Nations Framework Convention on Climate Change, must consider negative impacts on the environment from electricity generation. To meet these challenges, renewable resources are needed for cleaner electricity generation and ensuring security of electricity supply, while simultaneously …

Indonesia's Termination Of Bilateral Investment Treaties, Lucas Jun Hao Wong

Centre for Commercial Law in Asia

Indonesia holds a vast source of untapped potential in terms of its ability to influence global trade. While Indonesia has been a member of the World Trade Organization (WTO) since 1 January 1995, its integration into global value chains remains relatively weak, with the ratio of its trade in goods and services to GDP falling from 48.6% in 2013 to below 40% in 2019. Nonetheless, as Southeast Asia’s largest economy and a member of the G20, Indonesia possesses the capacity to become a key player on the world stage.

Trust In Robotics: A Multi-Staged Decision-Making Approach To Robots In Community, Wenxi Zhang, Willow Wong, Mark Findlay

Centre for AI & Data Governance (2019-2025)

Pivoting on the desired outcome of social good within the wider robotics ecosystem, trust is identified as the central adhesive of the HRI interface. However, building trust between humans and robots involves more than improving the machine’s technical reliability or trustworthiness in function. This paper presents a holistic, community-based approach to trust-building, where trust is understood as a multifaceted and multi-staged looped relation that depends heavily on context and human perceptions. Building on past literature that identifies dispositional and learned stages of trust, our proposed Decision to Trust model considers more extensively the human and situational factors influencing how trust …

Volunteerism Among Older Adults In Singapore, Micah Tan, John Frederic Pedro Ortega, Nur Syafiqah Abdullah, Mindy Eiko Tadai, Rachel Wen Yi Ngu

ROSA Research Briefs

Volunteerism is recognised as a beneficial activity for individuals for many reasons. Beyond the potential of volunteerism to create new and meaningful communities (Hodge et al., 2013), it offers numerous benefits including improvement to one’s mental health (Willigen, 2000), self-esteem (Russell et al., 2018), and social connectedness (Hodge et al., 2013). Volunteering has also been found to provide a sense of purpose in one’s life (Schwingel et al., 2009). For these reasons and more, voluntary work among older adults may be a meaningful and effective pathway towards successful ageing, particularly for those in retirement. In Singapore, the National Volunteer and …
