Free Articles And Accounting For The Timing Effect, Nursyeha Yahaya, Chee Hsien Aaron (Zheng Zhixian) Tay Dec 2016

Free Articles And Accounting For The Timing Effect, Nursyeha Yahaya, Chee Hsien Aaron (Zheng Zhixian) Tay

Research Collection Library

Various studies have attempted to assess the amount of free full text available on the web and recent work have suggested that we are close to the 50% mark for freely available articles (Archambault et al. 2013; Bjork et al. 2010; Jamali and Nabavi 2015). It is natural to wonder if this might reduce researchers' reliance on library subscriptions for access. To do so, we need to determine not just what papers researchers are citing to that are free today, but to estimate if the papers they were citing were freely available at the time they were citing it. We …

Weak Convergence To Stochastic Integrals For Econometric Applications, Hanying Liang, Peter C. B. Phillips, Hanchao Wang, Qiying Wang Dec 2016

Weak Convergence To Stochastic Integrals For Econometric Applications, Hanying Liang, Peter C. B. Phillips, Hanchao Wang, Qiying Wang

Research Collection School Of Economics

Limit theory involving stochastic integrals is now widespread in time series econometrics and relies on a few key results on functional weak convergence. In establishing such convergence, the literature commonly uses martingale and semimartingale structures. While these structures have wide relevance, many applications involve a cointegration framework where endogeneity and nonlinearity play major roles and complicate the limit theory. This paper explores weak convergence limit theory to stochastic integral functionals in such settings. We use a novel decomposition of sample covariances of functions of I (1) and I (0) time series that simplifies the asymptotics and our limit results for …

Endogenous Quality Choice, Signaling, And Welfare, Gea M. Lee, Seung Han Yoo Dec 2016

Endogenous Quality Choice, Signaling, And Welfare, Gea M. Lee, Seung Han Yoo

Research Collection School Of Economics

We consider a model in which each worker endogenously selects his own type through aprivate investment decision and selects a public signal in the labor market. Signaling thencontributes to social welfare through its influence on the quality choice. We offer a rationalefor the argument that there are too many high-type workers from a welfare perspective,identifying circumstances under which separating equilibrium generates too many high-typeworkers while having to use the incentive-compatible signal and treat high-type workersdifferently in the market. The inefficiency can then be reduced in pooling equilibrium.

Online Detection Of Behavioral Change Using Unobtrusive Eldercare Monitoring System, Thanh Tam La, Alvin Cerdena Valera, Hwee-Pink Tan, Cheryl Li Fang Koh Dec 2016

Online Detection Of Behavioral Change Using Unobtrusive Eldercare Monitoring System, Thanh Tam La, Alvin Cerdena Valera, Hwee-Pink Tan, Cheryl Li Fang Koh

Research Collection School Of Computing and Information Systems

The rapid ageing population is posing challenges to many countries all over the world, particularly in the provision of care to the growing number of elderly who are living alone. Allowing the elderly to age-in-place, i.e., live safely and independently in the comfort of their own homes is a model that can potentially address the resource constraint in health and community care faced by many nations. To make this model a reality and provide appropriate and timely care to the elderly, unobtrusive eldercare monitoring systems (EMS) are being deployed in real homes to continuously monitor the activity of the elderly. …

Cast2face: Assigning Character Names Onto Faces In Movie With Actor-Character Correspondence, Guangyu Gao, Mengdi Xu, Jialie Shen, Huangdong Ma, Shuicheng Yan Dec 2016

Cast2face: Assigning Character Names Onto Faces In Movie With Actor-Character Correspondence, Guangyu Gao, Mengdi Xu, Jialie Shen, Huangdong Ma, Shuicheng Yan

Research Collection School Of Computing and Information Systems

Automatically identifying characters in movies has attracted researchers' interest and led to several significant and interesting applications. However, due to the vast variation in character appearance as well as the weakness and ambiguity of available annotation, it is still a challenging problem. In this paper, we investigate this problem with the supervision of actor-character name correspondence provided by the movie cast. Our proposed framework, namely, Cast2Face, is featured by: 1) we restrict the assigned names within the set of character names in the cast; 2) for each character, by using the corresponding actor and movie name as keywords, we retrieve …

2016 – A Tumultuous Year Of The Revolt Against The Elites, Tan K. B. Eugene Dec 2016

2016 – A Tumultuous Year Of The Revolt Against The Elites, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan noted that 2016 will probably be remembered as the year of the populist revolt against the elites, against the backdrop of bewildering disruptions and an abiding sense of displacement and control accentuated by technological advancements. He highlighted that the critical challenge is to bring trust back into the core of the relationship between those in power and the masses, adding that governments need to purposively deal with people's resentments, fury and fears.

Orienteering Problem: A Survey Of Recent Variants, Solution Approaches And Applications, Aldy Gunawan, Hoong Chuin Lau, Pieter Vansteenwegen

Research Collection School Of Computing and Information Systems

The Orienteering Problem (OP) has received a lot of attention in the past few decades. The OP is a routing problem in which the goal is to determine a subset of nodes to visit, and in which order, so that the total collected score is maximized and a given time budget is not exceeded. A number of typical variants has been studied, such as the Team OP, the (Team) OP with Time Windows and the Time Dependent OP. Recently, a number of new variants of the OP was introduced, such as the Stochastic OP, the Generalized OP, the Arc OP, …

Understanding The Law Of Torts In China: A Political Economy Perspective, Wei Zhang Dec 2016

Understanding The Law Of Torts In China: A Political Economy Perspective, Wei Zhang

Research Collection Yong Pung How School Of Law

In this paper, I tried to connect the text of the Chinese tort law with the institutional context of lawmaking in China from a political economy perspective. Two determinants, political influence and populist pressure, were identified for the tort law legislation in China, and a simple spatial model was presented to demonstrate the mechanism through which these determinants might have affected the text of the law. In particular, my research suggested that, when injurers’ political influence kept constant, the populist pressure on the injurer group tended to push the tort law rules toward the pro-victim end. On the contrary, with …

The Use Of Scenarios In Legal Education To Develop Futures Thinking And Sustainability Competencies, Michelle Mei Ling Lim, Andrew Allan Dec 2016

The Use Of Scenarios In Legal Education To Develop Futures Thinking And Sustainability Competencies, Michelle Mei Ling Lim, Andrew Allan

Research Collection Yong Pung How School Of Law

Achieving sustainability requires a populace equipped to deal with complex, interacting and ever-changing realities as well as uncertain futures. There is however a significant lack of focus on developing sustainability competencies within legal and governance education. Legal education plays a key role in shaping sustainable futures. Long-term sustainability relies on lawyers, judges and policy-makers being able to make optimal decisions in the present when faced with significant uncertainty about the future. This paper discusses how the combination of problem-based learning (PBL) and scenario-based pedagogical approaches can provide an authentic contextualised learning environment to empower law students to deal with the …

Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia Kong, Chung-Yee Lee, Chung-Piaw Teo, Zhichao Zheng Dec 2016

Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia Kong, Chung-Yee Lee, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

We study the design of a healthcare appointment system with a single physician and a group of patients whose service durations are stochastic. The challenge is to find the optimal arrival sequence for a group of mixed patients such that the expected total cost of patient waiting time and physician overtime is minimized. While numerous simulation studies report that sequencing patients by increasing order of variance of service duration (Smallest-Variance-First or SVF rule) performs extremely well in many environments, analytical results on optimal sequencing are known only for two patients. In this paper, we shed light on why it is …

Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong Yang, Cayirli Tugba, Mei Wan Low Dec 2016

Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong Yang, Cayirli Tugba, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Existing models of multi-server queues with system transience and non-standard assumptions are either too complex or restricted in their assumptions to be used broadly in practice. This paper proposes using data analytics, combining computer simulation to generate the data and an advanced non-linear regression technique called the Alternating Conditional Expectation (ACE) to construct a set of easy-to-use equations to predict the performance of queues with a scheduled start and end time. Our results show that the equations can accurately predict the queue performance as a function of the number of servers, mean arrival load, session length and service time variability. …

Increase In Takeover Protection And Firm Knowledge Accumulation Strategy, Heli Wang, Shan Zhao, Jinyu He Dec 2016

Increase In Takeover Protection And Firm Knowledge Accumulation Strategy, Heli Wang, Shan Zhao, Jinyu He

Research Collection Lee Kong Chian School Of Business

Research summary: We argue that the extent to which a firm faces takeover threats affects its knowledge structure. In particular, takeover threats may lead to managers' reluctance to adopt a strategy toward firm-specific knowledge accumulation because implementing this strategy requires them to acquire specialized skills, which are at risk under takeover threats. Conversely, takeover protection leads to an increase in firm-specific knowledge. Further, the relationship between takeover protection and firm-specific knowledge is positively moderated by managerial ownership, which helps align managerial interests with those of shareholders. But the relationship is negatively moderated by managerial tenure, as long-tenured managers have already …

Management Research In Amj: Celebrating Impact While Striving For More, Gerard George Dec 2016

Management Research In Amj: Celebrating Impact While Striving For More, Gerard George

Research Collection Lee Kong Chian School Of Business

Over the years, I have read articles or listened to panel discussions that question the value of management scholarship, and often critiqued its relevance or insightfulness for an applied profession. On occasion, I have sided with those who are more pessimistic of our future as a field. While there are many truths in these commentaries, they might not give adequate credit to the robust knowledge production ecosystem that generates applied insight with scientific rigor. Yes, there is a lot more we can do but we should also celebrate the work we do well. Having read over 4000 manuscripts as an …

Understanding And Tackling Societal Grand Challenges Through Management Research, Gerard George, Jennifer Howard-Grenville, Aparna Joshi, Laszlo Tihanyi Dec 2016

Understanding And Tackling Societal Grand Challenges Through Management Research, Gerard George, Jennifer Howard-Grenville, Aparna Joshi, Laszlo Tihanyi

Research Collection Lee Kong Chian School Of Business

“Grand challenges” are formulations of global problems that can be plausibly addressed through coordinated and collaborative effort. In this Special Research Forum, we showcase management research that examines societal problems that individuals, organizations, communities, and nations face around the world. We develop a framework to guide future research to provide systematic empirical evidence on the formulation, articulation, and implementation of grand challenges. We highlight several factors that likely enhance or suppress the attainment of collective goals, and identify representative research questions for future empirical work. In so doing, we aspire to encourage management scholars to engage in tackling broader societal …

Limited Attention, Marital Events And Hedge Funds, Yan Lu, Sugata Ray, Melvyn Teo Dec 2016

Limited Attention, Marital Events And Hedge Funds, Yan Lu, Sugata Ray, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

We explore the impact of limited attention by analyzing the performance of hedge fund managers who are distracted by marital events. We find that marriages and divorces are associated with significantly lower fund alpha, during the six-month period surrounding and the two-year period after the event. Busy managers who manage multiple funds and who are not part of a team are more affected by marital transitions. Inattentive managers place fewer active bets relative to their style peers, load more on index stocks, exhibit higher R-squareds with respect to systematic factors, and are more prone to the disposition effect.

The Effect Of Monetary Policy On Bank Wholesale Funding, Hyunsoo Choi, Hyun Soo Choi Dec 2016

The Effect Of Monetary Policy On Bank Wholesale Funding, Hyunsoo Choi, Hyun Soo Choi

Research Collection Lee Kong Chian School Of Business

We study how monetary policy affects the funding composition of the banking sector. When monetary tightening reduces the retail deposit supply due to, for example, a decrease in bank reserves or in money demand, banks try to substitute the deposit outflows with more wholesale funding in order to mitigate the policy impact on their lending. Banks have varying degrees of accessibility to wholesale funding sources because of financial frictions, and those banks that are large or that have a greater reliance on wholesale funding increase their wholesale funding more. As a result, monetary tightening increases both the reliance on and …

Validating Social Media Data For Automatic Persona Generation, Jisun An, Haewoon Kwak, Bernard J Jansen

Research Collection School Of Computing and Information Systems

Using personas during interactive design has considerable potential for product and content development. Unfortunately, personas have typically been a fairly static technique. In this research, we validate an approach for creating personas in real time, based on analysis of actual social media data in an effort to automate the generation of personas. We validate that social media data can be implemented as an approach for automating generating personas in real time using actual YouTube social media data from a global media corporation that produces online digital content. Using the organization's YouTube channel, we collect demographic data, customer interactions, and topical …

Managing Egress Of Crowd During Infrastructure Disruption, Teck Hou Teng, Shih-Fen Cheng, Trong-Nghia Truong, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

In a large indoor environment such as a sports arena or convention center, smooth egress of crowd after an event can be seriously affected if infrastructure such as elevators and escalators break down. In this paper, we propose a novel crowd simulator known as SIM-DISRUPT for simulating egress scenarios in non-emergency situations. To surface the impact of disrupted infrastructure on the egress of crowd, SIM-DISRUPT includes features that allow users to specify selective disruptions as well as strategies for controlling the distribution and egress choices of crowd. Using SIM-DISRUPT, we investigate effects of crowd distribution, egress choices and infrastructure disruptions …

A Privacy-Preserving Outsourced Functional Computation Framework Across Large-Scale Multiple Encrypted Domains, Ximeng Liu, Baodong Qin, Robert H. Deng, Rongxing Lu, Jianfeng Ma Dec 2016

A Privacy-Preserving Outsourced Functional Computation Framework Across Large-Scale Multiple Encrypted Domains, Ximeng Liu, Baodong Qin, Robert H. Deng, Rongxing Lu, Jianfeng Ma

Research Collection School Of Computing and Information Systems

In this paper, we propose a framework for privacy-preserving outsourced functional computation across large-scale multiple encrypted domains, which we refer to as POFD. With POFD, a user can obtain the output of a function computed over encrypted data from multiple domains while protecting the privacy of the function itself, its input and its output. Specifically, we introduce two notions of POFD, the basic POFD and its enhanced version, in order to tradeoff the levels of privacy protection and performance. We present three protocols, named Multi-domain Secure Multiplication protocol (MSM), Secure Exponent Calculation protocol with private Base (SECB), and Secure Exponent …

Traffic Simulation Model For Port Planning And Congestion Prevention, Baoxiang Li, Kar Way Tan, Trong Khiem Tran

Research Collection School Of Computing and Information Systems

Effective management of land-side transportation provides the competitive advantage to port terminal operators in improving services and efficient use of limited space in an urban port. We present a hybrid simulation model that combines traffic-flow modeling and discrete-event simulation for land-side port planning and evaluation of traffic conditions for a number of what-if scenarios. We design our model based on a real-world case of a bulk cargo port. The problem is interesting due to complexity of heterogeneous closed-looped internal vehicles and external vehicles traveling in spaces with very limited traffic regulation (no traffic lights, no traffic wardens) and the traffic …

Efficient Online Summarization Of Large-Scale Dynamic Networks, Qiang Qu, Siyuan Liu, Feida Zhu, Christian S. Jensen Dec 2016

Efficient Online Summarization Of Large-Scale Dynamic Networks, Qiang Qu, Siyuan Liu, Feida Zhu, Christian S. Jensen

Research Collection School Of Computing and Information Systems

Information diffusion in social networks is often characterized by huge participating communities and viral cascades of high dynamicity. To observe, summarize, and understand the evolution of dynamic diffusion processes in an informative and insightful way is a challenge of high practical value. However, few existing studies aim to summarize networks for interesting dynamic patterns. Dynamic networks raise new challenges not found in static settings, including time sensitivity, online interestingness evaluation, and summary traceability, which render existing techniques inadequate. We propose dynamic network summarization to summarize dynamic networks with millions of nodes by only capturing the few most interesting nodes or …

Demystifying And Puncturing The Inflated Delay In Smartphone-Based Wifi Network Measurement, Weichao Li, Daoyuan Wu, Rocky K. C. Chang, Ricky K. P. Mok Dec 2016

Demystifying And Puncturing The Inflated Delay In Smartphone-Based Wifi Network Measurement, Weichao Li, Daoyuan Wu, Rocky K. C. Chang, Ricky K. P. Mok

Research Collection School Of Computing and Information Systems

Using network measurement apps has become a very effective approach to crowdsourcing WiFi network performance data. However, these apps usually measure the user-level performancemetrics instead of the network-level performance which is important for diagnosing performance problems. In this paper we report for the first time that a major source of measurement noises comes from the periodical SDIO (Secure Digital Input Output) bus sleep inside the phone. The additional latency introduced by SDIO and Power Saving Mode can inflate and unstablize network delay measurement significantly. We carefully design and implement a scheme to wake up the phone for delay measurement by …

Unauthorised Fiduciary Gains And The Constructive Trust, Alvin W. L. See Dec 2016

Unauthorised Fiduciary Gains And The Constructive Trust, Alvin W. L. See

Research Collection Yong Pung How School Of Law

This article challenges the traditional assumption that all cases of unauthorised fiduciary gain warrant the same legal treatment, in particular the imposition of a constructive trust as a disgorgement remedy. It proposes a method of categorising the cases and ranking them based on the strength of the principal’s interest. It is suggested that in cases where the principal’s interest is not particularly strong, there is room for taking into account the interests of innocent third parties and affording them the necessary protection. For this purpose, the remedial constructive trust supplies the needed flexibility.
