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
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
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.
Targets Tax Shelter Participation And Takeover Premiums, Travis Chow, Kenneth J. Klassen, Yanju Liu
Targets Tax Shelter Participation And Takeover Premiums, Travis Chow, Kenneth J. Klassen, Yanju Liu
Research Collection School Of Accountancy
This paper examines the effect of targets' participation in tax shelters on takeover premiums in mergers and acquisitions. Using a novel data set in which targets disclose that they have not participated in tax shelters, we find that targets that make this statement in their merger filings are associated with 4.6 percent higher takeover premiums, on average. These findings suggest that acquirers are concerned about the potential future liabilities when targets have engaged in tax sheltering. Consistent with this interpretation, the results also indicate that the positive association between targets' nonsheltering disclosure and acquisition premiums is stronger for less tax-aggressive …

Theory And Practice Of The Proposed Conceptual Framework: Evidence From The Field, Kevin Ow Yong, Chu Yeong Lim, Pearl Hock-Neo Tan
Research Collection School Of Accountancy
We provide survey evidence of chartered accountants' perspectives on the proposed conceptual framework of the International Accounting Standards Board. Our survey obtains their views on the changes in the definitions of assets and liabilities, recognition criterion, and additional guidance in these areas, as well as issues relating to other comprehensive income, business model-based accounting, and choice of measurement basis. Our field evidence suggests broad consensus with respect to most of these changes. The areas that generate the most disagreement among our respondents relate to the removal of economic benefits in the proposed asset definition, the proposal to remove the minimum …
The Benefits Of Specific Risk-Factor Disclosures, Ole-Kristian Hope, Danqi Hu, Hai Lu
The Benefits Of Specific Risk-Factor Disclosures, Ole-Kristian Hope, Danqi Hu, Hai Lu
Research Collection School Of Accountancy
Practitioners have long criticized risk-factor disclosures in the 10-K as generic and boilerplate. In response, regulators emphasize the importance of being specific. By using a computing algorithm, this paper establishes a new measure (Specificity) to quantify the level of specificity of firms’ qualitative risk-factor disclosures. We first examine determinants of variations in Specificity, and document that firms with high proprietary costs provide less specific risk-factor disclosures. More importantly, we find that, controlling for numerous determinants, the market reaction to the 10-K filing is positively and significantly associated with Specificity. In addition, our results suggest that analysts are better able to …

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. …

An Agent-Based Approach To Human Migration Movement, Larry Lin, Kathleen M. Carley, Shih-Fen Cheng
Research Collection School Of Computing and Information Systems
How are the populations of the world likely to shift? Which countries will be impacted by sea-level rise? This paper uses a country-level agent-based dynamic network model to examine shifts in population given network relations among countries, which influences overall population change. Some of the networks considered include: alliance networks, shared language networks, economic influence networks, and proximity networks. Validation of model is done for migration probabilities between countries, as well as for country populations and distributions. The proposed framework provides a way to explore the interaction between climate change and policy factors at a global scale.

This paper reports experiences made at an Asian university in developing a social media platform based on Twitter in the context of a final year capstone project where information systems management students get an opportunity to solve ‘a real-world problem for a real client’. In this case study, the challenge was provided by a faculty member’s request for an interactive social media application which engages less outspoken students in class via a social medium they are familiar with: Twitter. We reconstruct the project’s evolution; describe the main features of the application called ‘TweetBoard’ and share lessons learned in developing a …
Pairwise Relation Classification With Mirror Instances And A Combined Convolutional Neural Network, Jianfei Yu, Jing Jiang
Pairwise Relation Classification With Mirror Instances And A Combined Convolutional Neural Network, Jianfei Yu, Jing Jiang
Research Collection School Of Computing and Information Systems
Relation classification is the task of classifying the semantic relations between entity pairs in text. Observing that existing work has not fully explored using different representations for relation instances, especially in order to better handle the asymmetry of relation types, in this paper, we propose a neural network based method for relation classification that combines the raw sequence and the shortest dependency path representations of relation instances and uses mirror instances to perform pairwise relation classification. We evaluate our proposed models on two widely used datasets: SemEval-2010 Task 8 and ACE-2005. The empirical results show that our combined model together …

With the booming popularity of online social networks like Twitter and Weibo, online user footprints are accumulating rapidly on the social web. Simultaneously, the question of how to leverage the large-scale user-generated social media data for personal credit scoring comes into the sight of both researchers and practitioners. It has also become a topic of great importance and growing interest in the P2P lending industry. However, compared with traditional financial data, heterogeneous social data presents both opportunities and challenges for personal credit scoring. In this article, we seek a deep understanding of how to learn users’ credit labels from social …

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 …

Ciphertext-Policy Attribute-Based Encryption With Partially Hidden Access Structure And Its Application To Privacy-Preserving Electronic Medical Record System In Cloud Environment, Lixian Liu, Junzuo Lai, Robert H. Deng, Yingjiu Li
Research Collection School Of Computing and Information Systems
With the development of cloud computing, more and more sensitive data are uploaded to cloud by companies or individuals, which brings forth new challenges for outsourced data security and privacy. Ciphertext-policy attribute-based encryption (CP-ABE) provides fine-grained access control of encrypted data in the cloud; in a CP-ABE scheme, an access structure, also referred to as ciphertext-policy, is sent along with a ciphertext explicitly, and anyone who obtains a ciphertext can know the access structure associated with the ciphertext. In certain applications, access structures contain very sensitive information and must be protected from everyone except the users whose private key attributes …

Semi-Automated Tool For Providing Effective Feedback On Programming Assignments, Min Yan Beh, Swapna Gottipati, David Lo, Venky Shankararaman
Research Collection School Of Computing and Information Systems
Human grading of introductory programming assignments is tedious and error-prone, hence researchers have attempted to develop tools that support automatic assessment of programming code. However, most such efforts often focus only on scoring solutions, rather than assessing whether students correctly understand the problems. To aid the students improve programming skills, effective feedback on programming assignments plays an important role. Individual feedback generation is tedious and painstaking process. We present a tool that not only automatically generates the static and dynamic program analysis outcomes, but also clusters similar code submissions to provide scalable and effective feedback to the students. We studied …

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.
From Context To Text In Contractual Interpretation: Is There Really A Problem With The Plain Meaning Rule?, Yihan Goh
Research Collection Yong Pung How School Of Law
Much of the contemporary scholarship on contractual interpretation is staunchly against a textual analysis, by which a court can only depart from the plain meaning of a contract exceptionally. It is therefore no surprise that scholars have reacted negatively to the spate of recent cases where the English courts have re-emphasized the plain meaning of the text in contractual interpretation. Yet one cannot help but wonder whether a textual analysis is really so problematic when courts across the common law world have re-embraced it. Drawing from both theoretical and comparative perspectives, this paper suggests that a focus on the text …

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
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
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 …

Metro has become the first choice of traveling for tourists and citizens in metropolis due to its efficiency and convenience. Yet passengers have to rely on metro broadcasts to know their locations because popular localization services (e.g. GPS and wireless localization technologies) are often inaccessible underground. To this end, we propose MetroEye, an intelligent smartphone-based tracking system for metro passengers underground. MetroEye leverages low-power sensors embedded in modern smartphones to record ambient contextual features, and infers the state of passengers (Stop, Running, and Interchange) during an entire metro trip using a Conditional Random Field (CRF) model. MetroEye further provides arrival …

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
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
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 …

Socially Responsible Firms, Allen Ferrell, Hao Liang, Luc Renneboog
Research Collection Lee Kong Chian School Of Business
In the corporate finance tradition, starting with Berle and Means (1932), corporations should generally be run to maximize shareholder value. The agency view of corporate social responsibility (CSR) considers CSR an agency problem and a waste of corporate resources. Given our identification strategy by means of an instrumental variable approach, we find that well-governed firms that suffer less from agency concerns (less cash abundance, positive pay-for-performance, small control wedge, strong minority protection) engage more in CSR. We also find that a positive relation exists between CSR and value and that CSR attenuates the negative relation between managerial entrenchment and value.

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 …

“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 …
