Using Student-Generated Videos To Learn Internal Control In Accounting Information Systems Courses, Poh Sun Seow, Gary Pan

Research Collection School Of Accountancy

Educators consider the video learning approach an effective method to deliver educational content as compared to the traditional method of books and written materials. This paper presents a project that involves student-generated videos to learn internal control in an undergraduate accounting information systems course. We believe that this video learning approach is an engaging way for students to be self-directed learners in learning internal control and complements the written materials in the textbook. The survey results show that most of the respondents viewed the learning experience of the video project positively. The results also indicate that the video project was …

Why Do Publicly Listed Firms Evade Taxes: Evidence From China, Travis Chow, Bin Ke, Hongqi Yuan, Yao Zhang

Research Collection School Of Accountancy

Taking advantage of the mandatory disclosure of detected corporate tax evasions in China, we examine why publicly listed firms evade taxes. Different from most prior studies that focus on corporate income tax avoidance, we consider tax evasions related to both income taxes and non-income taxes. We also use a bivariate probit model to account for the partial observability of corporate tax evasion. Many of our regression results using the bivariate probit model are different from the results using the reduced form probit model that ignores the partial observability of tax evasion. Many of our results are also different from those …

Dynamic Nearest Neighbor Queries In Euclidean Space, Sarana Nutanong, Mohammed Eunus Ali, Egemen Tanin, Kyriakos Mouratidis

Research Collection School Of Computing and Information Systems

Given a query point q and a set D of data points, a nearest neighbor (NN) query returns the data point p in D that minimizes the distance DIST(q,p), where the distance function DIST(,) is the L₂norm. One important variant of this query type is kNN query, which returns k data points with the minimum distances. When taking the temporal dimension into account, the k NN query result may change over a period of time due to changes in locations of the query point and/or data points.

Exploiting Contextual Information For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The problem of fine-grained tweet geolocation is to link tweets to their posting venues. We solve this in a learning to rank framework by ranking candidate venues given a test tweet. The problem is challenging as tweets are short and the vast majority are non-geocoded, meaning information is sparse for building models. Nonetheless, although only a small fraction of tweets are geocoded, we find that they are posted by a substantial proportion of users. Essentially, such users have location history data. Along with tweet posting time, these serve as additional contextual information for geolocation. In designing our geolocation models, we …

A Multi-Agent System For Coordinating Vessel Traffic, Teck-Hou Teng, Hoong Chuin Lau, Akshat Kumar

Research Collection School Of Computing and Information Systems

Environmental, regulatory and resource constraints affects the safety and efficiency of vessels navigating in and out of the ports. Movement of vessels under such constraints must be coordinated for improving safety and efficiency. Thus, we frame the vessel coordination problem as a multi-agent path-finding (MAPF) problem. We solve this MAPF problem using a Coordinated Path-Finding (CPF) algorithm. Based on the local search paradigm, the CPF algorithm improves on the aggregated path quality of the vessels iteratively. Outputs of the CPF algorithm are the coordinated trajectories. The Vessel Coordination Module (VCM) described here is the module encapsulating our MAPF-based approach for …

Discovering Your Selling Points: Personalized Social Influential Tags Exploration, Yuchen Li, Kian-Lee Tan, Ju Fan, Dongxiang Zhang

Research Collection School Of Computing and Information Systems

Social influence has attracted significant attention owing to the prevalence of social networks (SNs). In this paper, we study a new social influence problem, called personalized social influential tags exploration (PITEX), to help any user in the SN explore how she influences the network. Given a target user, it finds a size-k tag set that maximizes this user’s social influence. We prove the problem is NP-hard to be approximated within any constant ratio. To solve it, we introduce a sampling-based framework, which has an approximation ratio of 1−ǫ 1+ǫ with high probabilistic guarantee. To speedup the computation, we devise more …

Stop Nuclear Smuggling Through Efficient Container Inspection, Xinrun Wang, Qingyu Guo, Bo An

Research Collection School Of Computing and Information Systems

Since 2003, the U.S. government has spent $850 million on the Megaport Initiative which aims at stopping the nuclear smuggling in international container shipping through advanced inspection facilities including Non-Intrusive Inspection (NII) and Mobile Radiation Detection and Identification System (MRDIS). Unfortunately, it remains a significant challenge to efficiently inspect more than 11.7 million containers imported to the U.S. due to the limited inspection resources. Moreover, existing work in container inspection neglects the sophisticated behavior of the smuggler who can surveil the inspector’s strategy and decide the optimal (sequential) smuggling plan. This paper is the first to tackle this challenging container …

South Africa And Sexual Orientation Rights At The United Nations: Batting For Both Sides, Eduard Jordaan

Research Collection School of Social Sciences

In 2011 South Africa led the UN Human Rights Council to adopt the first-ever UN resolution on sexual orientation. In 2014, South Africa was the only African state to support the follow-up to the 2011 resolution. These actions create the impression that South Africa is strongly committed to the international advancement of sexual orientation rights. However, this article scrutinises South Africa’s actions on sexual orientation rights at the UN for the period 1995–2015 and will demonstrate South Africa’s inconsistency, its frequent failures to support sexual orientation rights internationally, and its various actions against the advancement of these rights. The article …

Sector-Specific Development And Policy Vulnerability In The Philippines, Jacob I. Ricks

Research Collection School of Social Sciences

Why does a state build institutional capacity in certain sectors rather than others? Despite having gained leverage explaining the emergence of institutions in the developmental states of East Asia, we have comparatively weak accounts for sub‐national variation in institutional strength, a much more common phenomenon. Investigating the surprising achievements of the Philippines’ National Irrigation Administration, this article advances a theory of sectoral success in the face of a generally poor developmental record. The author demonstrates that executives will only construct institutional capacity when facing strong political pressure combined with resource scarcity. Such vulnerability permits politicians to exercise discretion in choosing …

Policy Learning And Policy Networks In Theory And Practice: The Role Of Policy Brokers In The Indonesian Biodiesel Policy Network, Michael Howlett, Ishani Mukherjee, Joop Koppenjan

Research Collection School of Social Sciences

This paper examines how learning has been treated, generally, in policy network theories and what questions have been posed, and answered, about this phenomenon to date. We examine to what extent network characteristics and especially the presence of various types of brokers impede or facilitate policy learning. Next, a case study of the policy network surrounding the sustainability of palm oil biodiesel in Indonesia over the past two decades is presented using social network analysis. This case study focuses on sustainability-oriented policy learning in the Indonesian biodiesel governance network and illustrates how network features and especially forms of brokerage influence …

Attention To Context During Evaluative Learning And Context-Dependent Automatic Evaluation: A Cross-Cultural Analysis, Yang Ye, Yuk-Yue Tong, Chi-Yue Chiu, Bertram Gawronski

Research Collection School of Social Sciences

Previous research has shown that changes in automatic evaluations can be limited to the context in which counterattitudinal information was acquired. This effect has been attributed to enhanced attention to context cues during the encoding of expectancy-violating counterattitudinal information. Drawing on previous evidence for cultural differences in attention to context and tolerance for inconsistency, the present research examined cultural differences in responses to conflicting evaluative information and the resulting context-effects on automatic evaluation. Study 1 revealed that both Canadian and Singaporean participants showed enhanced attention to context during exposure to counterattitudinal information. In a reanalysis of studies with Singaporean participants, …

Signs Of Social Class: The Experience Of Economic Inequality In Everyday Life, Michael W. Kraus, Jun Won Park, Jacinth J. X. Tan

Research Collection School of Social Sciences

By some accounts, global economic inequality is at its highest point on record. The pernicious effects of this broad societal trend are striking: Rising inequality is linked to poorer health and well-being across countries, continents, and cultures. The economic and psychological forces that perpetuate inequality continue to be studied, and in this theoretical review, we examine the role of daily experiences of economic inequality—the communication of social class signals between interaction partners—in this process. We theorize that social class signals activate social comparison processes that strengthen group boundaries between the haves and have nots in society. In particular, we argue …

Messaging Without A Message: Executive Value And Social Media Activity, Ru Gao, Gilles Hilary, Rencheng Wang

Research Collection School Of Accountancy

We show that executives who start tweeting benefit from better career options. We motivate this finding using the well-established theory of limited attention. Consistent with this explanation, we find that content is irrelevant. Comparative statics are also consistent with our framework. In particular, the effect of Twitter is greater for executives who were largely unrecognized and who were underpaid before they started tweeting, who garner greater public attention from their social media activity, who enjoy higher professional mobility, and who operate in environments where compensation setting is less structured.

The Value Of Trading Relations In Turbulent Times, Marco Di Maggio, Amir Kermani, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

This paper investigates how dealers’ trading relations shape their trading behavior in the corporate bond market. Dealers charge lower spreads to dealers with whom they have the strongest ties and more so during periods of market turmoil. Systemically important dealers exploit their connections at the expense of peripheral dealers as well as clients, charging higher markups than to other core dealers. Also, intermediation chains lengthened by 20% following the collapse of a flagship dealer in 2008 and even more for institutions strongly connected to this dealer. Finally, dealers drastically reduced their inventory during the crisis.

The Four Horsemen Of Power At The Bargaining Table, Adam D. Galinsky, Michael Schaerer, Joe C. Magee

Research Collection Lee Kong Chian School Of Business

This paper aims to identify and discuss four major sources of power in negotiations. Findings: The four sources of power are alternatives, information, status and social capital. Each of these sources of power can enhance a negotiator’s likelihood of obtaining their ideal outcome because power allows negotiators to be more confident and proactive, and it shields them from the bargaining tactics of their opponents. Practical implications: The paper discusses how negotiators can utilize each source of power to improve their negotiation outcomes. Originality/value: The paper provides a parsimonious definition of power in negotiations, identifies the four major sources of negotiator …

Moral Traps: When Self-Serving Attributions Backfire In Prosocial Behavior, Stephanie C. Lin, Julian J. Zlatev, Dale T. Miller

Research Collection Lee Kong Chian School Of Business

Two assumptions guide the current research. First, people's desire to see themselves as moral disposes them to make attributions that enhance or protect their moral self-image: When approached with a prosocial request, people are inclined to attribute their own noncompliance to external factors, while attributing their own compliance to internal factors. Second, these attributions can backfire when put to a material test. Studies 1 and 2 demonstrate that people who attribute their refusal of a prosocial request to an external factor (e.g., having an appointment), but then have that excuse removed, are more likely to engage in prosocial behavior than …

Passing The Baton: Getting The 4g Leadership Ready, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan discussed the latest Cabinet changes and what it means for the fourth-generation (4G) leadership. He noted that given the demands and vagaries of politics and public office, it is advantageous for the 4G leadership to be adequately staffed, and to possess sufficient depth and breadth in their ranks. As it stands, the 4G leadership has a predominantly public sector or military background prior to entering politics. He also added that next year’s reshuffle is likely to see most, if not all, of the 4G leadership being reassigned ministerial portfolios, to …

Managing The Inter-Cultural Dimensions Of A Mediation Effectively: A Proposed Pre-Mediation Intake Instrument, Dorcas Quek Anderson, Diana Knight

Research Collection Yong Pung How School Of Law

Being a culturally responsive mediator has become increasingly challenging amidst the growing cultural complexity within many societies. Drawing on the existing research on culture and the authors’ experiences of mediating disputes amongst diverse disputants in Australia and Singapore, this paper proposes an emic-constructivist approach for the mediator to understand the individual disputant’s unique cultural preferences. It also recommends bringing forward the exercise of understanding cultural preferences through conducting pre-mediation intake interviews. It is argued that this approach enables the mediator to embrace the parties’ cultural complexity and to design the mediation process based on their rich milieu of preferences. Finally, …

The Asian Perspective On Smes In International Economic Law: Opportunities And Challenges Arising From The Tpp, Heng Wang

Research Collection Yong Pung How School Of Law

The Trans-Pacific Partnership (TPP) is likely to have profound implications for small and medium-sized enterprises (SMEs) within and beyond the free trade area. The key question will be analysed: what are the challenges and opportunities that the TPP hold for SMEs? It is argued that, first, the key benefits the TPP can be expected to bring for SMEs are enhanced market liberalization and a more predictable regulatory environment. Second, the TPP poses serious challenges for SMEs (eg insufficiency of the opportunities to SMEs, the complexity of rules, difficulties in rule interpretation and implementation, and remaining regulatory differences), but different types …

Navigating The New Terrain Of A Reserved Election, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan discussed the workings of the upcoming Singapore presidential election. He noted that as the next election is a reserved one, all the more voters should specially consider a candidate’s commitment and contributions to multiracialism. On the reserved election mechanism, Associate Prof Tan noted that it helps ensure that the presidency is not only accessible, but is seen to be accessible to all the major racial communities in Singapore.“It functions as an inter-generational safeguard for minority representation, while not going as far as mechanically rotating the presidency among the major races, …

A Tale Of Two Chinese Cultural Centres, 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 opening of the Singapore Chinese Cultural Centre (SCCC), located in the financial district. He noted that the opening of the SCCC, established by the Singapore Federation of Chinese Clan Associations, marks another milestone in Singapore’s multiracialism, adding that Chinese Singaporeans can also manifest their identity and culture without being perceived to be exclusive or domineering.Comparing the SCCC to the Chinese Cultural Centre (CCC), established by China’s government during China’s President Xi Jinping’s state visit to Singapore in November 2015, Associate Prof Tan said although Singapore …

Future Directions In Personality, Occupational And Medical Selection: Myths, Misunderstandings, Measurement, And Suggestions, Eamonn Ferguson, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This paper has two objectives: (1) presenting recent advances in personality theory whereby personality traits are conceptualized within a framework that focuses on the dynamic interactions of behaviour, biology, context, and states, and (2) discussing the implications of these developments for measurement and medical selection. We start by presenting evidence that traits are no longer regarded as stable deterministic predictors of behaviour. Instead, traits are found to change across generations, the life span, and in response to environmental contingencies. Thus, there is an urgent need to explore how traits change as function of medical education. Second, drawing on recent theory …

Construct-Driven Sjts: Toward An Agenda For Future Research, Filip Lievens

Research Collection Lee Kong Chian School Of Business

A common theme running through recent research on Situational Judgment Tests (SJTs) and this special issue is the aim to improve the measurement of constructs via SJTs. Construct-driven SJTs differ from traditional SJTs in that they present a trait activating situation to test-takers and a more unidimensional set of response options that depict different trait levels. In this commentary, I frame the different papers of this special issue into a research agenda related to construct-driven SJTs. Specifically, I posit that future research should examine whether construct-driven SJTs lead to more unidimensionality at the item level, cleaner measurement of the constructs, …

On Time-Varying Factor Models: Estimation And Testing, Liangjun Su, Xia Wang

Research Collection School Of Economics

Conventional factor models assume that factor loadings are fixed over a long horizon of time, which appears overly restrictive and unrealistic in applications. In this paper, we introduce a time-varying factor model where factor loadings are allowed to change smoothly over time. We propose a local version of the principal component method to estimate the latent factors and time-varying factor loadings simultaneously. We establish the limiting distributions of the estimated factors and factor loadings in the standard large N and large T framework. We also propose a BIC-type information criterion to determine the number of factors, which can be used …

A Specification Test Based On The Mcmc Output, Yong Li, Jun Yu, Tao Zeng

Research Collection School Of Economics

A test statistic is proposed to assess themodel specification after the model is estimated by Bayesian MCMC methods. Thenew test is motivated from the power enhancement technique of Fan, Liao and Yao(2015). It combines a component (J1) that tests anull point hypothesis in an expanded model and a power enhancement component (J0) obtained from the null model. It is shown that J0 converges to zero when the null model is correctly specified anddiverges when the null model is misspecified. Also shown is that J1 is asymptotically X2-distributed, suggesting that theproposed test is asymptotically pivotal, when the null model is correctlyspecified. …

In-Fill Asymptotic Theory For Structural Break Point In Autoregression: A Unified Theory, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

This paper obtains the exact distribution of the maximum likelihood estimatorof structural break point in the OrnsteinñUhlenbeck process when a continuousrecord is available. The exact distribution is asymmetric, tri-modal, dependenton the initial condition. These three properties are also found in the önite sampledistribution of the least squares (LS) estimator of structural break point inautoregressive (AR) models. Motivated by these observations, the paper then developsan in-öll asymptotic theory for the LS estimator of structural break point inthe AR(1) coe¢ cient. The in-öll asymptotic distribution is also asymmetric, trimodal,dependent on the initial condition, and delivers excellent approximationsto the önite sample distribution. Unlike …
