Transnational Mobilities And The Making Of Creative Cities, Lily Kong
Transnational Mobilities And The Making Of Creative Cities, Lily Kong
Research Collection School of Social Sciences
This review essay on the literature on creative cities pays particular attention to the ways in which transnational mobilities contribute significantly to the making of such cities. The paper reviews critically both the literature and phenomena of creative cities and their transnational flows by framing the discussion around the mobility of ideas (creative economy/creative city discourse), the mobility of people (the migration of the creative class), the mobility of technology (the travel of the creative cluster and architectural iconism phenomena), the mobility of finances (capital and investment flows), and the mobility of images (transnational artistic collaborations and products).
Historical Traffic-Tolerant Paths In Road Networks, Pui Hang Li, Man Lung Yiu, Kyriakos Mouratidis
Historical Traffic-Tolerant Paths In Road Networks, Pui Hang Li, Man Lung Yiu, Kyriakos Mouratidis
Research Collection School Of Computing and Information Systems
Historical traffic information is valuable for transportation analysis and planning, as well as for route search services. In view of these applications, we propose the k traffic-tolerant paths problem (TTP) on road networks, which takes a source-destination pair and historical traffic information as input, and returns k paths that minimize the aggregate (historical) travel time. Unlike the shortest path problem, the TTP problem has a combinatorial search space that renders the optimal solution expensive to compute. We propose an exact algorithm and a heuristic algorithm for this problem. Experiments on real traffic data demonstrate the effectiveness of TTP paths and …
Policy Design And Non-Design: Towards A Spectrum Of Policy Formulation Types, Michael Howlett, Ishani Mukherjee
Policy Design And Non-Design: Towards A Spectrum Of Policy Formulation Types, Michael Howlett, Ishani Mukherjee
Research Collection School of Social Sciences
Public policies are the result of efforts made by governments to alter aspects of behaviour—both that of their ownagents and of society at large—in order to carry out some end or purpose. They are comprised of arrangements of policygoals and policy means matched through some decision-making process. These policy-making efforts can be more,or less, systematic in attempting to match ends and means in a logical fashion or can result from much less systematicprocesses. “Policy design” implies a knowledge-based process in which the choice of means or mechanisms throughwhich policy goals are given effect follows a logical process of inference from …
The Evolution Of Research On Multimedia Travel Guide Search And Recommender Systems, Junge Shen, Zhiyong Cheng, Jialie Shen, Tao Mei, Xinbo Gao
The Evolution Of Research On Multimedia Travel Guide Search And Recommender Systems, Junge Shen, Zhiyong Cheng, Jialie Shen, Tao Mei, Xinbo Gao
Research Collection School Of Computing and Information Systems
The importance of multimedia travel guide search and recommender systems has led to a substantial amount of research spanning different computer science and information system disciplines in recent years. The five core research streams we identify here incorporate a few multimedia computing and information retrieval problems that relate to the alternative perspectives of algorithm design for optimizing search/recommendation quality and different methodological paradigms to assess system performance at large scale. They include (1) query analysis, (2) diversification based on different criteria, (3) ranking and reranking, (4) personalization and (5) evaluation. Based on a comprehensive discussion and analysis of these streams, …
From Cultural Industries To Creative Industries And Back? Towards Clarifying Theory And Rethinking Policy, Lily Kong
Research Collection School of Social Sciences
In this paper, I draw attention to the complexities and confusions in the shift in discourse and praxis from "culture industry" to "cultural industries" and then "creative industries." I examine how this "creative turn" is fraught with challenges, highlighting seven issues in particular: (i) the difficulties in defining and scoping the creative industries; (ii) the challenges in measuring the economic benefits creative industries bring; (iii) the risk that creative industries neglect genuine creativity/culture; (iv) the utopianization of "creative labour"; (v) the risk of valorizing and promoting external expertise over local small- and medium-scale enterprises in the building of "creative industries"; …
Time-Series Data Mining In Transportation: A Case Study On Singapore Public Train Commuter Travel Patterns, Roy Ka Wei Lee, Tin Seong Kam
Time-Series Data Mining In Transportation: A Case Study On Singapore Public Train Commuter Travel Patterns, Roy Ka Wei Lee, Tin Seong Kam
Research Collection School Of Computing and Information Systems
The adoption of smart cards technologies and automated data collection systems (ADCS) in transportation domain had provided public transport planners opportunities to amass a huge and continuously increasing amount of time-series data about the behaviors and travel patterns of commuters. However the explosive growth of temporal related databases has far outpaced the transport planners’ ability to interpret these data using conventional statistical techniques, creating an urgent need for new techniques to support the analyst in transforming the data into actionable information and knowledge. This research study thus explores and discusses the potential use of time-series data mining, a relatively new …

Press: A Novel Framework Of Trajectory Compression In Road Networks, Renchu Song, Weiwei Sun, Baihua Zheng, Yu Zheng
Press: A Novel Framework Of Trajectory Compression In Road Networks, Renchu Song, Weiwei Sun, Baihua Zheng, Yu Zheng
Research Collection School Of Computing and Information Systems
Location data becomes more and more important. In this paper, we focus on the trajectory data, and propose a new framework, namely PRESS (Paralleled Road-Network-Based Trajectory Compression), to effectively compress trajectory data under road network constraints. Different from existing work, PRESS proposes a novel representation for trajectories to separate the spatial representation of a trajectory from the temporal representation, and proposes a Hybrid Spatial Compression (HSC) algorithm and error Bounded Temporal Compression (BTC) algorithm to compress the spatial and temporal information of trajectories respectively. PRESS also supports common spatial-temporal queries without fully decompressing the data. Through an extensive experimental study …
Experiments On Crowdsourcing Policy Assessment, John Prpić, Araz Taeihagh, James Melton
Experiments On Crowdsourcing Policy Assessment, John Prpić, Araz Taeihagh, James Melton
Research Collection School of Social Sciences
Can Crowds serve as useful allies in policy design? How do non-expert Crowds perform relative to experts in the assessment of policy measures? Does the geographic location of non-expert Crowds, with relevance to the policy context, alter the performance of non-experts Crowds in the assessment of policy measures? In this work, we investigate these questions by undertaking experiments designed to replicate expert policy assessments with non-expert Crowds recruited from Virtual Labor Markets. We use a set of ninety-six climate change adaptation policy measures previously evaluated by experts in the Netherlands as our control condition to conduct experiments using two discrete …
A Framework For Policy Crowdsourcing, John Prpić, Araz Taeihagh, James Melton
A Framework For Policy Crowdsourcing, John Prpić, Araz Taeihagh, James Melton
Research Collection School of Social Sciences
What is the state of the literature in respect to Crowdsourcing for policy making? This work attempts to answer this question by collecting, categorizing, and situating the extant research investigating Crowdsourcing for policy, within the broader Crowdsourcing literature. To do so, the work first extends the Crowdsourcing literature by introducing, defining, explaining, and using seven universal characteristics of all general Crowdsourcing techniques, to vividly draw-out the relative trade-offs of each mode of Crowdsourcing. From this beginning, the work systematically and explicitly weds the three types of Crowdsourcing to the stages of the Policy cycle as a method of situating the …

Housing Policies In Singapore: Evaluation Of Recent Proposals And Recommendations For Reform, Sock Yong Phang, David K. C. Lee, Alan Cheong, Kok Fai Phoon, Karol Wee
Research Collection Lee Kong Chian School Of Business
The Singapore housing market is unusual in its high homeownership rate, the dominance of HDB housing, and the extensive intervention of the government in regulating housing supply and demand in both the HDB and private housing sectors. Recent rapid population increases in a low interest rate and high global liquidity environment has resulted in accelerated house prices increases in Singapore. Earlier this year, the government launched “Our Singapore Conversation” of which discussion on housing policies constitutes one major component. This “conversation” comes in the wake of several consecutive rounds of measures to stabilize housing prices using various instruments. This paper …
How To Boost Spain’S Business Presence In Singapore: Opportunities In The Wake Of The Free Trade Agreement With The Eu, Maria Garcia, Clara Portela
How To Boost Spain’S Business Presence In Singapore: Opportunities In The Wake Of The Free Trade Agreement With The Eu, Maria Garcia, Clara Portela
Research Collection School of Social Sciences
The recently signed Free Trade Agreement between the EU and Singapore opens up new business opportunities for Spanish companies on the island, which is already Spain’s top trading partner in South-East Asia. One highlight of the accord is the elimination of restrictions on the percentage of foreign investment in financial services and sectors such telecommunications, engineering and shipping. At the same time, the possibility of being able to bid on more government contracts can help companies involved in environmental protection and construction firms. The food industry will benefit from the novel creation of a registry of geographical indications.

Recently, Early Warning Signals (EWS) have been developed to predict tipping points in Earth Systems. This discussion highlights the potential to apply EWS to human social and economic systems, which may also undergo similar critical transitions. Social tipping points are particularly difficult to predict, however, and the current formulation of EWS, based on a physical system analogy, may be insufficient. As an alternative set of EWS for social systems, we join with other authors encouraging a focus on heterogeneity, connectivity through social networks and individual thresholds to change.
A Paradoxical Approach To Policymaking, David Chan
A Paradoxical Approach To Policymaking, David Chan
Research Collection School of Social Sciences
In an invited commentary, SMU Behavioural Sciences Institute Director Professor David Chan discussed the tensions between Singapore’s goals to become a global city and maintain national solidarity. Building on Prime Minister Lee Hsien Loong’s recent speech in London which emphasised that Singapore “must get the balance just right”, Professor Chan noted the limitations of adopting a “give-and-take” mindset to the city-country paradox. He suggested several strategic principles for dynamic balancing between city and country goals. He provided the example of building Singapore’s cultural capital and policy adaptations to illustrate the issues.

Unilateral Emissions Mitigation, Spillovers, And Global Learning, Shurojit Chatterji, Sayantan Ghosal, Sean Walsh, John Whalley
Research Collection School Of Economics
What's the role of unilateral measures in global climate change mitigation in a post-Durban, post 2012 global policy regime? We argue that under conditions of preference heterogeneity, unilateral emissions mitigation at a subnational level may exist even when a nation is unwilling to commit to emission cuts. We establish that under certain assumptions, in a global strongly connected network of countries, learning the costs of switching to a low emissions activity can result in a universal adoption of such activities. We analyze the features of a policy proposal that could accelerate convergence to a low carbon world in the presence …

Crowdsourcing The Policy Cycle, John Prpić, Araz Taeihagh, James Melton
Crowdsourcing The Policy Cycle, John Prpić, Araz Taeihagh, James Melton
Research Collection School of Social Sciences
Crowdsourcing is beginning to be used for policymaking. The “wisdom of crowds” [Surowiecki 2005], and crowdsourcing [Brabham 2008], are seen as new avenues that can shape all kinds of policy, from transportation policy [Nash 2009] to urban planning [Seltzer and Mahmoudi 2013], to climate policy. In general, many have high expectations for positive outcomes with crowdsourcing, and based on both anecdotal and empirical evidence, some of these expectations seem justified [Majchrzak and Malhotra 2013]. Yet, to our knowledge, research has yet to emerge that unpacks the different forms of crowdsourcing in light of each stage of the well-established policy cycle. …
Managing Private Vehicles In Asian Cities, Sock-Yong Phang
Managing Private Vehicles In Asian Cities, Sock-Yong Phang
Research Collection School Of Economics
Asia's rapid urbanization and growing incomes have resulted in a corresponding booming market in motor vehicle sales. In 2013, an estimated 18 million new passenger cars were sold in China. Motor vehicle users generate congestion, pollution, accidents, noise and road damage. Yet, in most cities motor vehicle users often do not pay the full social costs and are therefore implicitly subsidized by non-users. According to the Tom Tom Traffic Index, which is based on GPS data, motorists in the worst congested cities in developed countries spend up to 40% more time for peak hour commutes. This level of delay is …
The Elements Of Effective Program Design: A Two-Level Analysis, Michael Howlett, Ishani Mukherjee, Jeremy Rayner
The Elements Of Effective Program Design: A Two-Level Analysis, Michael Howlett, Ishani Mukherjee, Jeremy Rayner
Research Collection School of Social Sciences
Policy and program design is a major theme of contemporary policy research, aimed at improving the understanding of how the processes, methods and tools of policy-making are employed to better formulate effective policies and pro-grams, and to understand the reasons why such designs are not forthcoming. However while many efforts have been made to evaluate policy design, less work has focused on program designs. This article sets out to fill this gap in knowledge of design practices in policy-making. It outlines the nature of the study of policy design with a particular focus on the nature of programs and the …

An Air Index For Spatial Query Processing In Road Networks, Weiwei Sun, Chunan Chen, Baihua Zheng, Chong Chen, Peng Liu
Research Collection School Of Computing and Information Systems
Spatial queries such as range query and kNN query in road networks have received a growing number of attention in real life. Considering the large population of the users and the high overhead of network distance computation, it is extremely important to guarantee the efficiency and scalability of query processing. Motivated by the scalable and secure properties of wireless broadcast model, this paper presents an air index called Network Partition Index (NPI) to support efficient spatial query processing in road networks via wireless broadcast. The main idea is to partition the road network into a number of regions and then …
Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh
Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh
Research Collection Lee Kong Chian School Of Business
Research shows that exposure to heat-related cues (e.g., warm temperatures, “fry” and “boil”) influences the belief that global warming exists and poses a serious threat to humans. Drawing on social-cognitive principles of concept accessibility and applicability, we hypothesized that these effects may depend on how the issue is framed, given that heat-related concepts are more compatible with “global warming” than “climate change.” Exploring this possibility, we asked campus passersby about their belief in global warming or climate change shortly after a real-life unseasonably cold weather event (i.e., snowfall during Spring; Study 1). A controlled Web experiment …

Mechanisms For Arranging Ride Sharing And Fare Splitting For Last-Mile Travel Demands, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau
Research Collection School Of Computing and Information Systems
A great challenge of city planners is to provide efficient and effective connection service to travelers using public transportation system. This is commonly known as the last-mile problem and is critical in promoting the utilization of public transportation system. In this paper, we address the last-mile problem by considering a dynamic and demand-responsive mechanism for arranging ride sharing on a non-dedicated commercial fleet (such as taxis or passenger vans). Our approach has the benefits of being dynamic, flexible, and with low setup cost. A critical issue in such ride-sharing service is how riders should be grouped and serviced, and how …
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang
Research Collection School Of Economics
The fundamental law of highway congestion states that when congested, the travel speed on an expanded expressway reverts to its previous level before the capacity expansion. In this paper, we propose a theory that generalizes this statement and finds that if there exists a coverage effect, that is, the effect of longer road length on traffic conditional on capacity, then the new equilibrium travel speed could be lower than its previous level. Given the fundamental law, the theory predicts that the elasticity of traffic to road capacity is at least 1. We estimate this elasticity for national expressways in Japan …

The New Capitalism: Asia And The Future Of Business, Government, And Society, Ann Florini, Bindu Sharma
Research Collection School of Social Sciences
To have a conversation, the appropriate language is needed. The language is just starting to emerge in both Asia and the West for one of the most important conversations the world is now having—the discussion about the future of business and capitalism. Thailand’s King Bhumibol refers to the sufficiency economy. Harvard’s Michael Porter speaks of shared value. Ellen MacArthur’s eponymous foundation supports the transition to the circular economy. John Elkington proposes breakthrough capitalism. Bhutan’s call to measure progress by gross national happiness (GNH), rather than the narrow metric of gross domestic product (GDP), is now attracting attention around the globe. …

Media Frames And Cognitive Accessibility: What Do "Global Warming" And "Climate Change" Evoke Partisan Minds?, Jonathon P. Schuldt, Sungjong Roh
Research Collection Lee Kong Chian School Of Business
Decades of research demonstrate that how the public thinks about a given issue is affected by how it is framed by the media. Typically, studies of framing vary how an issue is portrayed (often, by altering the text of written communication) and compare subsequent beliefs, attitudes, or preferences—taking a framing effect as evidence that a media frame (or frame in communication) instantiated a particular audience frame (or frame in thought). Less work, however, has attempted to measure frames in thought directly, which may illuminate cognitive mechanisms that underlie framing effects. In this vein, we describe a Web experiment (n = …
