Of Facts And Falsehoods, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan shared his views on the proposed Protection from Online Falsehoods and Manipulation Bill (POFMB). He surmised that POFMB is “a necessary but insufficient tool” against the scourge of “fake news” and that it must be applied sensitively in order not to undermine but enhance Singaporeans’ resilience and bottom-up drive to fight deliberate harmful falsehoods.

Looking Beyond The Vague Terms In Singapore's Fake News Laws, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

Protection from Online Falsehoods andManipulation Act (Pofma), some criticised it for being too vague. Pofma contains words and phrases whose meaning is not explicitlyclear, e.g. statements that are “falseor misleading”, but does not define “misleading”. But case law gives us aclearer understanding of what “misleading” means

An Improved Bayesian Unit Root Test In Stochastic Volatility Models, Yong Li, Jun Yu

Research Collection School Of Economics

A new posterior odds analysis is developed to test for a unit root in volatilitydynamics in the context of stochastic volatility models. Our analysis extendsthe Bayesian unit root test of So and Li (1999) in two important ways. First,a mixed informative prior distribution with a random weight is introducedfor the Bayesian unit root testing in volatility. Second, a numerically morestable algorithm is introduced to compute Bayes factor, taking into accountthe special structure of the competing models. It can be shown that theapproach introduced overcomes the problem of the diverging “size” in themarginal likelihood approach by So and Li (1999) and …

Does India's Growth Matter? Evidence From The Saarc Nations, Rohan Ray, Cledwyn Fernandez

Research Collection School Of Economics

The study estimates the extent of spillover effects that India's real per capita gross domestic product (GDP) growth rate has on the growth rates of other countries in the South Asian Association for Regional Cooperation (SAARC) region for the period 2003–2016. It also identifies whether the conventional trade channel is the means through which growth is transmitted from India to her neighboring countries. Using a random effects model, we conclude that on average, a 1 percentage point increase in India's real per capita GDP growth rate results in 0.46 percentage point increase in the per capita GDP growth rates of …

Editorial Introduction To The Special Issue Entitled: Spatial Econometrics: New Methods And Applications, Zhenlin Yang

Research Collection School Of Economics

Spatial econometrics is a fast growing research area, with the theories and methods developed over the past five decades or so being applied more and more widely, not only in the specialized fields such as regional science, real estate, economic geography, and urban economics, but also increasingly in the general fields such as economics, finance and social networks, in particular in the recent decade. One of the driving forces is perhaps the formation of the Spatial Econometrics Association (SEA) at Rome in 2006 and its subsequent annul conference started in 2007 at the Cambridge University, which have helped greatly the …

Wage-Vacancy Contracts And Multiplicity Of Equilibria In A Directed Search Model Of The Labor Market, Nicolas L. Jacquet, John Kennes, Serene Tan

Research Collection School Of Economics

This paper studies a directed search model of the labour market, which is standard in all aspects except two. First, we allow firms to post wage–vacancy contracts advertising the number of workers they would pay as well as the payment all will receive. Second, we consider two cases: one where workers are risk neutral and one where workers are risk averse, both in finite and large economies. Our paper shows that when firms post wage–vacancy contracts, whether workers are modelled as risk neutral or risk averse matters: the types of symmetric equilibria and the nature of multiplicity of equilibria are …

Housing Equity And Household Consumption In Retirement: Evidence From The Singapore Life Panel, Lipeng Chen, Liang Jiang, Sock Yong Phang, Jun Yu

Research Collection School Of Economics

We utilize data from the Singapore Life Panel© survey to empirically investigate the impact of housing equity on consumption of elderly households. Based on panel analysis, we find housing equity value has no significant impact on non-durable consumption for elderly people. The conclusion holds for a battery of robustness check. Moreover, heterogeneity analyses based on subsamples by age of household head, house type, and number of property possessed also show no significant impact of housing equity on consumption in general. Finally, we use scenario analysis to study the Lease Buyback Scheme (LBS), a novel housing equity monetization scheme which allows …

Equal-Quantile Rules In Resource Allocation With Uncertain Needs, Yan Long, Jay Sethuraman, Jingyi Xue

Research Collection School Of Economics

A group of agents have uncertain needs on a resource, and the resource has to be divided before uncertainty resolves. We propose a class of division rules we call equal-quantile rules, parameterized by λ ∈ (0, 1]. The parameter λ is a common maximal probability of satisfaction — the probability that an agent’s realized need is no more than his assignment — imposed on all agents. Thus, the maximal assignment of each agent is his λ-quantile assignment. If the endowment of the resource exceeds the sum of the agents’ λ-quantile assignments, each agent receives his λ-quantile assignment and the resource …

Jump Factor Models In Large Cross-Sections, Jia Li, Viktor Todorov, George. Tauchen

Research Collection School Of Economics

We develop tests for deciding whether a large cross-section of asset prices obey an exact factor structure at the times of factor jumps. Such jump dependence is implied by standard linear factor models. Our inference is based on a panel of asset returns with asymptotically increasing cross-sectional dimension and sampling frequency, and essentially no restriction on the relative magnitude of these two dimensions of the panel. The test is formed from the high-frequency returns at the times when the risk factors are detected to have a jump. The test statistic is a cross-sectional average of a measure of discrepancy in …

Making Ethnic Tourism Good For The Poor, Jean Junying Lor, Shelly Kwa, John A. Donaldson

Research Collection School of Social Sciences

How can ethnic tourism alleviate rural poverty? Due to the difficulty of simultaneously expanding tourism while promoting pro-poor tourism, most villages traverse one of two developmental pathways: 1) ensuring an inclusive structure before expanding, or 2) expanding before building an inclusive structure. This study compares four comparable cases in Southwestern China to understand the politics behind the decision to choose different pathways, and the impact each pathways has on local residents. While the first pathway requires a careful balance to maintain a pro-poor structure as tourism volume expands, the second pathway presents apparently insurmountable barriers to poverty reduction due to …

Mixed Bayesian Implementation In General Environments, Takashi Kunimoto

Research Collection School Of Economics

A social choice rule is said to be mixed Bayesian implementable if one can design a mechanism (or institution) in which the set of all mixed Bayesian Nash equilibrium outcomes coincides with that specified by the rule. The objective of this paper is to generalize the results of mixed Bayesian implementation. By means of example, I first assess the implication of common priors in Bayesian implementation. Second, I identify a mild condition that fills the gap between the necessity and sufficiency for mixed Bayesian implementation in general environments including non-economic ones. Third, I establish some new results to unify the …

Our main result connects therevealed preference analysis to the well-known lattice structure of the set of stablematchings, and tests the rationalizability of a data set by analyzing the joins andmeets of matchings.

Neo-Daoism In Stanford Encyclopedia Of Philosophy, Alan Kam Leung Chan

Research Collection College of Integrative Studies

The term “Neo-Daoism” (or “Neo-Taoism”) seeks to capture the focal development in early medieval Chinese philosophy, roughly from the third to the sixth century C.E. Chinese sources generally identify this development as Xuanxue, or “Learning (xue) in the Profound (xuan).”

When Essentialism Facilitates Intergroup Conflict Resolution: The Positive Role Of Perspective-Taking, Donna J. Yao, Melody M. Chao, Angela K. Y. Leung

Research Collection School of Social Sciences

Essentialism, a fundamental belief of the fixedness of social group essences, is often associated with negative intergroup outcomes. However, research is yet to explore the role of essentialism in intergroup conflicts, despite their prevalence. To address this gap, we conducted the first direct examination on how essentialism influences conflict management toward out-group members. Moreover, we examined perspective-taking as a positive factor in improving conflict management among essentialist individuals relative to their non-essentialist counterparts in intergroup contexts. Results across three experiments provided little support to the negative effect of essentialism on intergroup (vs. intragroup) conflict management. Yet, we found that perspective-taking …

Mobilising Dissent In A Digital Age: The Curious Case Of Amos Yee, Orlando Woods

Research Collection School of Social Sciences

Political containers frame opinions. They play a formative role in establishing the terms ofinterpretation, in distinguishing between assent and dissent, and in determining the extent towhich dissent is publicly tolerated. Whilst it is by now widely acknowledged that the powerand influence of political containers has been relativised by interconnection, the effects ofmoving within and between containers – and thus mediating between different framings ofopinion – is undertheorised. Also, the enabling role of digital media in disseminating dissent,and in bringing about disproportionate reach and impact, remains understudied. Addressingthese lacunae, this paper explores the ways in which dissent can be reproduced, reframed, …

Dumbing Down?: Trends In The Complexity Of Political Communication, Kenneth Benoit, Kevin Munger, Arthur Spirling

Research Collection School of Social Sciences

Commentators and some political scholars claim to have observed a “dumbing down” in the level of sophistication of political language, leading to anxiety over the quality of democratic deliberation, knowledge, policy design, and implementation. This work typically focuses on the president’s State of the Union addresses. Using quantitative indicators of textual complexity, we measure trends since 1790 in that and other key political corpora, including rulings of the Supreme Court, the Congressional Record, and presidential executive orders. To draw comparative lessons, we also study political texts from the United Kingdom, in the form of party broadcasts and manifestos. Not only …

Adaptive Resonance Theory (Art) For Social Media Analytics, Lei Meng, Ah-Hwee Tan, Donald C. Ii Wunsch

Research Collection School Of Computing and Information Systems

The last decade has witnessed how social media in the era of Web 2.0 reshapes the way people communicate, interact, and entertain in daily life and incubates the prosperity of various user-centric platforms, such as social networking, question answering, massive open online courses (MOOC), and e-commerce platforms. The available rich user-generated multimedia data on the web has evolved traditional ways of understanding multimedia research and has led to numerous emerging topics on human-centric analytics and services, such as user profiling, social network mining, crowd behavior analysis, and personalized recommendation. Clustering, as an important tool for mining information groups and in-group …

Personalized Web Image Organization, Lei Meng, Ah-Hwee Tan, Donald C. Wunsch

Research Collection School Of Computing and Information Systems

Due to the problem of semantic gap, i.e. the visual content of an image may not represent its semantics well, existing efforts on web image organization usually transform this task to clustering the surrounding text. However, because the surrounding text is usually short and the words therein usually appear only once, existing text clustering algorithms can hardly use the statistical information for image representation and may achieve downgraded performance with higher computational cost caused by learning from noisy tags. This chapter presents using the Probabilistic ART with user preference architecture, as introduced in Sects. 3.5 and 3.4, for personalized web …

Online Multimodal Co-Indexing And Retrieval Of Social Media Data, Lei Meng, Ah-Hwee Tan, Donald C. Wunsch

Research Collection School Of Computing and Information Systems

Effective indexing of social media data is key to searching for information on the social Web. However, the characteristics of social media data make it a challenging task. The large-scale and streaming nature is the first challenge, which requires the indexing algorithm to be able to efficiently update the indexing structure when receiving data streams. The second challenge is utilizing the rich meta-information of social media data for a better evaluation of the similarity between data objects and for a more semantically meaningful indexing of the data, which may allow the users to search for them using the different types …

Socially-Enriched Multimedia Data Co-Clustering, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Heterogeneous data co-clustering is a commonly used technique for tapping the rich meta-information of multimedia web documents, including category, annotation, and description, for associative discovery. However, most co-clustering methods proposed for heterogeneous data do not consider the representation problem of short and noisy text and their performance is limited by the empirical weighting of the multimodal features. This chapter explains how to use the Generalized Heterogeneous Fusion Adaptive Resonance Theory (GHF-ART) generalized heterogeneous fusion adaptive resonance theory for clustering large-scale web multimedia documents. Specifically, GHF-ART is designed to handle multimedia data with an arbitrarily rich level of meta-information. For handling …

Project Sidewalk: A Web-Based Crowdsourcing Tool For Collecting Sidewalk Accessibility Data At Scale, Manaswi Saha, Michael Saugstad, Hanuma Maddali, Aileen Zeng, Ryan Holland, Steven Bower, Aditya Dash, Sage Chen, Anthony Li, Kotaro Hara, Jon Froehlich

Research Collection School Of Computing and Information Systems

We introduce Project Sidewalk, a new web-based tool that enables online crowdworkers to remotely label pedestrian-related accessibility problems by virtually walking through city streets in Google Street View. To train, engage, and sustain users, we apply basic game design principles such as interactive onboarding, mission-based tasks, and progress dashboards. In an 18-month deployment study, 797 online users contributed 205,385 labels and audited 2,941 miles of Washington DC streets. We compare behavioral and labeling quality differences between paid crowdworkers and volunteers, investigate the effects of label type, label severity, and majority vote on accuracy, and analyze common labeling errors. To complement …

Perspectives On The 21st Century Urban University From Singapore: A Viewpoint Forum, Jean-Paul D. Addie, Michele Acuto, K. C. Ho, Stephan Cairns, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

In this Cities viewpoint forum, we argue that there is a need to rethink U.S./U.K.-centric approaches to the urban university in policy and practice. Gathering three critical commentaries by practitioners from within the Singaporean higher education system, the forum responds to the challenges of: (1) broadened expectation placed on higher education institutions; (2) the pressures and possibilities of global urbanization; and (3) the provocation to theorize the urban, and thus the urban university, from beyond the 'Global North'. Following an introduction detailing the history and relevance of the Singaporean case, the three viewpoints seek to illustrate the various dimensions of …
