Lawbreaker: An Approach For Specifying Traffic Laws And Fuzzing Autonomous Vehicles, Yang Sun, Christopher M. Poskitt, Jun Sun, Yuqi Chen, Zijiang Yang

Research Collection School Of Computing and Information Systems

Autonomous driving systems (ADSs) must be tested thoroughly before they can be deployed in autonomous vehicles. High-fidelity simulators allow them to be tested against diverse scenarios, including those that are difficult to recreate in real-world testing grounds. While previous approaches have shown that test cases can be generated automatically, they tend to focus on weak oracles (e.g. reaching the destination without collisions) without assessing whether the journey itself was undertaken safely and satisfied the law. In this work, we propose LawBreaker, an automated framework for testing ADSs against real-world traffic laws, which is designed to be compatible with different scenario …

Local, Yet Global: Implications Of Caste For Mnes And International Business, Hari Bapuji, Snehanjali Chrispal, Balagopal Vissa, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

Caste is an informal institution that influences socioeconomic action in many contexts. It is becoming increasingly evident that international business research, practice, and policy need to programmatically address caste. To facilitate this endeavour, we review the limited research in IB that has addressed caste, and theorize caste as a distinct informal institution by distinguishing it from systems of stratification like race, class, and gender. In addition, we propose a parsimonious framework to highlight the implications of caste for Indian and non-Indian MNEsin their Indian and global operations. In doing this, we focus on implications with respect to the internal organization …

Two Singapore Public Healthcare Ai Applications For National Screening Programs And Other Examples, Andy Wee An Ta, Han Leong Goh, Christine Ang, Lian Yeow Koh, Ken Poon, Steven M. Miller

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 …

People believe they should consider how their behavior might negatively impact other people, Yet their behavior often increases others’ health risks. This creates challenges for managing public health crises like the COVID-19 pandemic. We examined a procedure wherein people reflect on their personal criteria regarding how their behavior impacts others’ health risks. We expected structured reflection to increase people's intentions and decisions to reduce others’ health risks. Structured reflection increases attention to others’ health risks and the correspondence between people's personal criteria and behavioral intentions. In four experiments during COVID-19, people (N = 12,995) reported their personal criteria about how …

Looking Beyond The 'Middle Class' For Other Chinas, Qian Forrest Zhang

Research Collection School of Social Sciences

There are high hopes for China’s middle class. Thanks to their rising disposable income, this group of Chinese is expected to unleash a consumer revolution in the domestic market. However, I argue that the ‘middle class’ as a concept provides at best a partial understanding of the Chinese consumer population; at worst, it can even provide a misleading perspective that brings us to erroneous conclusions about its profile and size. Instead, I propose the notion of ‘three Chinas’ as an alternative way to make sense of China’s consumers. ‘First China’ comprises residents in medium and large-sized cities, ‘Second China’ consists …

Sense Of Control Mediates The Relation Between Discrimination And Executive Functions In Middle-Aged And Older Adults: A Structural Equation Modeling Approach, Wee Qin Ng, Gilaine Rui Ng, Hwajin Yang

Research Collection School of Social Sciences

Background Despite previous findings of a negative association between everyday discrimination and executive functions (EF) - a set of domain-general cognitive control processes - in middle-aged and older adults, less is known about the underlying mechanism. Thus, we focused on sense on control and its two facets - perceived constraints and personal mastery - as potential psychosocial mediators of this relation. Methods By analyzing a nationally representative adult cohort from the Midlife Development in the United States (MIDUS) 2 study, we examined two mediational models: a single mediation model with sense of control and a parallel mediation model with perceived …

Outdoor Thermal Comfort Research In Transient Conditions: A Narrative Literature Review, Yuliya Dzyuban, Graces N. Y. Ching, Sin Kang Yik, Adrian J. Tan, Shreya Banerjee, Peter Jay Crank, Winston T. L. Chow

Research Collection College of Integrative Studies

In recent years, urban planners and designers are paying greater attention to Outdoor Thermal Comfort (OTC) studies due to the imminent threat of the Urban Heat Island and climate change on human health. Historically, indoor thermal comfort research assumed steady-state conditions, centralizing on the concept of thermal neutrality to determine optimal environmental parameters. Such research pivoted to investigating how non-steady-state, transient environmental conditions influence comfort. Recent studies underscore the usefulness of positive alliesthesia in providing a productive framework for OTC evaluation. In this article we first clarify the concepts related to thermal comfort-related terms, scales, and models in the literature. …

An Est Approach To Entrepreneurial Exit In Chinese Family Business: A Case Study Of H Company, Lidian Zhang

Dissertations and Theses Collection (Open Access)

Previous entrepreneurial exit literature has mostly followed a feature-oriented logic by summarizing the impact of industry and company characteristics and entrepreneurs’ personal traits on entrepreneurial exit decisions, disregarding the decision-making process of entrepreneurial exit and the role of key events in advancing the process. This thesis endeavors to explore the determining factors behind entrepreneurial exit decisions of family businesses and the dynamic decision-making process based on Event System Theory (EST) with a single-case study method and a feature-oriented and process-oriented approach.

This study has conducted an in-depth investigation into Company H, which possesses typical features of Chinese private family businesses. …

Dissertations and Theses Collection (Open Access)

As a major sport country, China’s football is facing tricky problems of insufficient reserve players and football culture alienation. Improving the quality of youth football training not only can supplement a large number of reserve players, but also shape a sound football culture, which is a good approach to the current problems of China’s football. Based on the theory of customer engagement, this dissertation starts from the reality of Chinese youth football training, analyzes the problems existing in current youth football training in depth, and proposes that convenience, interest and empathy can improve the customer engagement of youth trainees. Outland …

Analysing Impacts Of Urban Morphological Variables And Density On Outdoor Microclimate For Tropical Cities: A Review And A Framework Proposal For Future Research Directions, Shreya Banerjee, Ngai Yan Ching, Sin Kang Yik, Yuliya Dzyuban, Peter Jay Crank, Xin Yi Pek, Winston T. L. Chow

Research Collection College of Integrative Studies

Modifying urban morphology, defined as mass, density, and orientation of building stock in cities, are well-known heat mitigation strategies addressing urban heat islands (UHI) at various scales and consequent thermal discomfort. However, varying morphological aspects may have divergent effects on Outdoor Thermal Comfort (OTC) in cities. Unlike UHI, which is derived from urban-rural temperature differences, OTC can be quantified by thermal comfort indices considering the objective assessment of microclimatic variables including air temperature (Ta), relative humidity (RH), mean radiant temperature (TMRT), and wind speed (Va), as well as a subjective assessment of individual perception. In Singapore and other tropical cities, …

The Sun Is Rising In The East: Dual-Class Shares And The Competitive Landscape Of Technological Industries In Asia, Hao Liang, Tran Bao Phuong Nguyen, Wei Zhang

Research Collection Lee Kong Chian School Of Business

There has recently been a relaxation of listing regulations to accommodate and attract firms going public with dual-class shares (DCS), notably in Asia. We examine the value implications of DCS adoption by employing an event study around a regulatory change allowing DCS listings in Hong Kong. We find negative market reactions around these regulatory discussions for firms already listed in Hong Kong, especially for firms in technology (tech) sectors. However, the market reaction turned positive for tech firms during Hong Kong’s first DCS listing. We identify two distinct channels that influenced shareholders’ perspectives on DCS: the competition channel, which dominated …

When Tensions Become Opportunities: Managing Accountability Demands In Collaborative Governance, Seulki Lee

Research Collection School of Social Sciences

Accountability in collaborative governance comprises a tangled web of vertical and horizontal accountability relationships. While different accountability mechanisms are apparently complementary, they also clash with each other, producing serious accountability tensions. This study explores how actors in collaborative governance experience and manage conflicting accountability demands in the context of a Korean interorganizational network. Using qualitative data based on in-depth interviews with 32 personnel across 10 organizations and document analysis, the study identifies different types of accountability tensions and actors’ strategic responses to them. The analysis reveals that accountability tensions vary across the sources of the demand, and they are more …

A Daily Diary Investigation Of The Fear Of Missing Out And Diminishing Daily Emotional Well-Being: The Moderating Role Of Cognitive Reappraisal, Andree Hartanto, Joax Wong, Verity Yu Qing Lua, Yue Qi Germaine Tng, K. T. A. Sandeeshwara Kasturiratna, Nadyanna M. Majeed

Research Collection School of Social Sciences

With modern societies becoming ever-increasingly interconnected due to technology and media, we have gained unprecedented access and exposure to other people’s lives. This has resulted in a greater desire to constantly be socially connected with the activities of others, or the fear of missing out (FoMO). While much of the present available research has established the association between FoMO and diminished emotional well-being, little has been done to identify protective factors that can help one cope with the negative psychological consequences of FoMO. Utilizing data from a 7-day diary study of a large sample of young adults (N = 261), …

From Pulau To Pulo: Archipelagic Perspectives On Southeast Asian Chinese Ethnicity From The Philippines And Indonesia, Josh Stenberg, Chien-Wen Kung, Charlotte Setijadi

Research Collection School of Social Sciences

Southeast Asia is an important region for working through ques-tions of Chineseness. It is, however, a notoriously heterogeneous region, and conclusions derived from some parts of it can be of limited applicability elsewhere. This special issue offering empiri-cally-grounded, multi-disciplinary research engages with and expands on existing scholarship on Southeast Asia’s Chinese. By focusing on Indonesia and the Philippines, the articles in this special issue investigate diverse models of being Chinese in Southeast Asia and depart from the familiar paradigms offered by Singapore and Malaysia, where ethnic Chinese populations are in the highest proportions and hold significant political power, and where …

Made In Singapore, Pao-Li Chang, Tran Bao Phuong Nguyen

Research Collection School Of Economics

In this paper, we characterize the position of Singapore in global value chains and identify Singapore’s key upstream and downstream trade partners. We trace how the position of Singapore in global value chains has changed in the past two decades: whether it has moved upstream or downstream, how involved it is in global value chains, how its trend compares with the other major Asian exporters (China, Japan, Korea, Taiwan and Hong Kong), and which key sectors of Singapore play a major role in these global trade networks.

Good Names Beget Favors: The Impact Of Country Image On Trade Flows And Welfare, Pao-Li Chang, Tomoki Fujii, Wei Jin

Research Collection School Of Economics

This paper estimates the effects of time-varying consumer preference bias on trade flows and welfare. We use a unique data set from the BBC World Service Poll, which surveys (annually during 2005–2017 with some gaps) the populations of a wide array of countries on their views of whether an evaluated country is having a mainly positive or negative influence in the world. We identify the effects on consumer preference parameters due to shifts in these country image perceptions and quantify their general equilibrium effects on bilateral exports and welfare (each time for an evaluated exporting country, holding the exporting country’s …

Disentangling The Effects Of Gatt/Wto On Variable And Fixed Trade Costs: Trade Status, Trade Margins, And Export Sales Distribution, Pao-Li Chang, Renjing Chen, Wei Jin

Research Collection School Of Economics

In this paper, we develop an estimation procedure to identify the partial (direct) effects of the GATT/WTO membership on the variable and the fixed trade cost, re-spectively. This extends the techniques of Anderson and Van Wincoop (2003) on the structural relationship of multilateral resistance terms and of Helpman, Melitz and Rubinstein (2008) on the structural modelling of trade incidence. We then develop a general equilibrium framework (that allows the presence of zero trade) to simulate the impact of variable, fixed, and total trade cost changes on the firm-level trade structure (including bilateral export productivity cutoff, weighted/unweighted extensive margin of export, …

Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yiu Lim Lui, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A heteroskedasticity-autocorrelation robust (HAR) test statistic is proposed to test for the presence of explosive roots in financial or real asset prices when the equation errors are strongly dependent. Limit theory for the test statistic is developed and extended to heteroskedastic models. The new test has stable size properties unlike conventional test statistics that typically lead to size distortion and inconsistency in the presence of strongly dependent equation errors. The new procedure can be used to consistently time-stamp the origination and termination of an explosive episode under similar conditions of long memory errors. Simulations are conducted to assess the finite …

On The Optimal Forecast With The Fractional Brownian Motion, Xiaohu Wang, Chen Zhang, Jun Yu

Research Collection School Of Economics

This paper examines the performance of alternative forecasting formulae with the fractional Brownian motion based on a discrete and finite sample. One formula gives the optimal forecast when a continuous record over the infinite past is available. Another formula gives the optimal forecast when a continuous record over the finite past is available. Alternative discretiza-tion schemes are proposed to approximate these formulae. These alternative discretization schemes are then compared with the conditional expectation of the target variable on the vector of the discrete and finite sample. It is shown that the conditional expectation delivers more accurate forecasts than the discretization-based …

Low-Rank Panel Quantile Regression: Estimation And Inference, Yiren Wang, Yichong Zhang, Yichong Zhang

Research Collection School Of Economics

In this paper, we propose a class of low-rank panel quantile regression models which allow for unobserved slope heterogeneity over both individuals and time. We estimate the heterogeneous intercept and slope matrices via nuclear norm regularization followed by sample splitting, row- and column-wise quantile regressions and debiasing. We show that the estimators of the factors and factor loadings associated with the intercept and slope matrices are asymptotically normally distributed. In addition, we develop two specification tests: one for the null hypothesis that the slope coefficient is a constant over time and/or individuals under the case that true rank of slope …
