Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson Jan 2011

Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson

Research Collection School Of Economics

Prior to the crisis the consensus amongst central bankers in advanced economies was that price stability, in the form of low and stable price inflation, was a top priority for monetary policy and could best be achieved by targeting interest rates (usually overnight) or monetary aggregates, such as Narrow Money (M1) and Broad Money (M2). Liquidity in the banking system could be flexibly adjusted on a daily basis through open market operations to increase or decrease the monetary base which would be transmitted to the rest of the economy through financial intermediation. Financial markets would then adjust longer-term interest rates …

International Entrepreneurship And Capability Development: Qualitative Evidence And Future Research Directions, Erkko Autio, Gerard George, Oliver Alexy Jan 2011

International Entrepreneurship And Capability Development: Qualitative Evidence And Future Research Directions, Erkko Autio, Gerard George, Oliver Alexy

Research Collection Lee Kong Chian School Of Business

In this article, we explore how new capabilities emerge and solidify in new ventures that are faced with fundamental uncertainty from their environment. To do so, we draw from the organizational and entrepreneurial literature on cognition and capabilities. Using initial qualitative evidence from a multi-firm study in the context of new venture internationalization, we develop a cognition-based model of capability emergence in new ventures. Our findings extend the capability development and learning implications of internationalization to the fundamental character of organizing processes in start-ups. Moreover, we derive avenues for future entrepreneurship research on the origins and evolution of capabilities in …

Applicant Versus Employee Scores On Self-Report Emotional Intelligence Measures, Filip Lievens, Ute-Christine Klehe, Nele Libbrecht Jan 2011

Applicant Versus Employee Scores On Self-Report Emotional Intelligence Measures, Filip Lievens, Ute-Christine Klehe, Nele Libbrecht

Research Collection Lee Kong Chian School Of Business

There exists growing interest to assess applicants' emotional intelligence (EI) via self-report trait-based measures of EI as part of the selection process. However, some studies that experimentally manipulated applicant conditions have cautioned that in these conditions use of self-report measures for assessing EI might lead to considerably higher scores than current norm scores suggest. So far, no studies have scrutinized self-reported EI scores among a sample of actual job applicants. Therefore, this study compares the scores of actual applicants at a large ICT organization (n = 109) on a well-known self-report measure of EI to the scores of employees already …

The Law Of Abandonment And The Passing Of Property In Trash, Cheng Lim Saw Jan 2011

The Law Of Abandonment And The Passing Of Property In Trash, Cheng Lim Saw

Research Collection Yong Pung How School Of Law

This article examines the law of abandonment – primarily in the context of rubbish disposal – from a comparative perspective. It will, in particular, consider whether the owner of moveable property can, in theory, divest himself of ownership rights therein by simply abandoning the chattel in question, and whether the common law recognises such a concept of (unilateral) divesting abandonment. Additionally, the article will examine how, if at all, the notion of abandonment – as it is understood and applied in relation to physical property – may also operate in the realm of intangible property.

The Fundamental Question When Applying The Welfare Principle: "Who Will Be The Better Parent Or Guardian"?, Siyuan Chen Jan 2011

The Fundamental Question When Applying The Welfare Principle: "Who Will Be The Better Parent Or Guardian"?, Siyuan Chen

Research Collection Yong Pung How School Of Law

The welfare principle – that is, when making a custody-related decision, the best interests of the child form the first and paramount consideration – is probably one of the cardinal principles of family law in many common law jurisdictions. While the welfare principle is generally considered a wide concept with no exhaustive definition or list of factors, it is submitted that there is an important question – sometimes neglected or misunderstood – that should actually feature most prominently when applying the welfare principle, particularly when joint or no order custody orders seem impossible. The question is simply that of “who …

Some Technological Implications For Ascertaining The Contents Of Contracts In Web-Based Transactions, Eliza Mik Jan 2011

Some Technological Implications For Ascertaining The Contents Of Contracts In Web-Based Transactions, Eliza Mik

Research Collection Yong Pung How School Of Law

This paper points out some unexpected relationships between specific aspects of contract law and specific Internet-related technologies. The discussion is not about the interplay between “Law” and “Technology,” or the “Law” and the “Internet.” The aim is modest: to identify some theoretical chokepoints created by the technologies involved in web-based commerce and to point out the legal uncertainties persisting in this area. The analysis is confined to the process of contract formation, not to matters of substantive law. It is during this process that parties assume their contractual obligations and the contents of a contract crystallize.

The Shareholder’S Personal Claim: Allowing Recovery For Reflective Loss, Pearlie Koh Jan 2011

The Shareholder’S Personal Claim: Allowing Recovery For Reflective Loss, Pearlie Koh

Research Collection Yong Pung How School Of Law

An absolute application of the no reflective loss principle can result in unfairness. As such, retaining judicial discretion in the area will do much to ensure that genuine causes are not denied remedy. However, even as our courts appear prepared to allow a shareholder to recover for reflective loss, it is important that corporate autonomy is accorded due respect, and not be obscured by an overconsideration of policy concerns. To ensure this, the courts should allow recovery only if the right asserted by the shareholder is one that is separate and independent of the company’s right.

Contractual Interpretation In Singapore After Zurich Insurance: Continued Refinement, Yihan Goh Jan 2011

Contractual Interpretation In Singapore After Zurich Insurance: Continued Refinement, Yihan Goh

Research Collection Yong Pung How School Of Law

Ever since Lord Hoffmann’s authoritative restatement of the principles relating to the interpretation of contracts in Investors Compensation Scheme v West Bromwich Building Society, various common law courts and academics have weighed in with their views on two main issues: whether the contextual approach articulated in Investors in fact represents a step forward from the traditional literal approach; and, accepting the operation of the contextual approach, whether there remains room for the exclusion of certain extrinsic evidence in interpreting contracts. But the foremost consideration underpinning these issues is that of the perceived uncertainty which the contextual approach brings. The Singapore …

Markowitz Meets Talmud: A Combination Of Sophisticated And Naive Diversification Strategies, Jun Tu, Guofu Zhou Jan 2011

Markowitz Meets Talmud: A Combination Of Sophisticated And Naive Diversification Strategies, Jun Tu, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

The modern portfolio theory pioneered by Markowitz (1952) is widely used in practice and extensively taught to MBAs. However, the estimated Markowitz portfolio rule and most of its extensions not only underperform the naive 1/N rule (that invests equally across N assets) in simulations, but also lose money on a risk-adjusted basis in many real data sets. In this paper, we propose an optimal combination of the naive 1/N rule with one of the four sophisticated strategies—the Markowitz rule, the Jorion (1986) rule, the MacKinlay and Pástor (2000) rule, and the Kan and Zhou (2007) rule—as a way to improve …

Integrating Ioob And Jdm Through Process-Oriented Research, Jochen Reb Dec 2010

Integrating Ioob And Jdm Through Process-Oriented Research, Jochen Reb

Research Collection Lee Kong Chian School Of Business

One of the most fascinating and counterintuitive insights from negotiation theory is that differences, rather than similarities, open up opportunities for value creation (Raiffa, 2002). Because of different values, beliefs, and perspectives, parties can benefit from their complementarities. Ironically though, negotiators tend to prefer negotiating with similar others, with others they like, presumably because negotiators expect interactions to proceed more smoothly. Differences make interaction more difficult but also potentially more rewarding, if managed correctly.

Measurement Equivalence Of The Wong And Law Emotional Intelligence Scale Across Self And Other Ratings, Nele Libbrecht, Filip Lievens, Eveline Schollaert Dec 2010

Measurement Equivalence Of The Wong And Law Emotional Intelligence Scale Across Self And Other Ratings, Nele Libbrecht, Filip Lievens, Eveline Schollaert

Research Collection Lee Kong Chian School Of Business

There exist a variety of measurement instruments for assessing emotional intelligence (EI). One approach is the use of other reports wherein knowledgeable informants indicate how well the scale items describe the assessed person's behavior. In other reports, the same EI scales are typically used as in self-reports. However, it is not known whether the measurement structure underlying EI ratings is equivalent across self and other ratings. In this study, the measurement equivalence of an extant EI measure (Wong and Law Emotional Intelligence Scale [WLEIS]) across self and other ratings was tested. Using multiple group confirmatory factor analysis, the authors conducted …

3-D Virtual World Education: An Empirical Comparison With Face-To-Face Classroom, Xiaofeng Chen, Keng Siau, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

3-D virtual worlds are increasing in popularity as a means of pedagogical delivery in higher education. In this research, we assess the relative effectiveness of a 3-D virtual world learning environment, Second Life, and traditional face-to-face learning environment. We also assess the efficacy of instructional strategies in these two learning environments and their effects on interactivity, perceived learning, and satisfaction. Our findings suggest that there is an interaction effect of learning environment and instructional strategy. Pair-wise comparisons indicate that when interactive instructional strategy is used, there is no significant difference for perceived learning and satisfaction between 3-D virtual world and …

Dynamic Group Key Exchange Revisited, Guomin Yang, Chik How Tan Dec 2010

Dynamic Group Key Exchange Revisited, Guomin Yang, Chik How Tan

Research Collection School Of Computing and Information Systems

In a dynamic group key exchange protocol, besides the basic group setup protocol, there are also a join protocol and a leave protocol, which allow the membership of an existing group to be changed more efficiently than rerunning the group setup protocol. The join and leave protocols should ensure that the session key is updated upon every membership change so that the subsequent sessions are protected from leaving members (backward security) and the previous sessions are protected from joining members (forward security). In this paper, we present a new security model for dynamic group key exchange. Comparing to existing models, …

Time Cost Evaluation For Executing Rfid Authentication Protocols, Kevin Chiew, Yingjiu Li, Tieyan Li, Robert H. Deng, Manfred Aigner Dec 2010

Time Cost Evaluation For Executing Rfid Authentication Protocols, Kevin Chiew, Yingjiu Li, Tieyan Li, Robert H. Deng, Manfred Aigner

Research Collection School Of Computing and Information Systems

There are various reader/tag authentication protocols proposed for the security of RFID systems. Such a protocol normally contains several rounds of conversations between a tag and a reader and involves cryptographic operations at both reader and tag sides. Currently there is a lack of benchmarks that provide a fair comparison platform for (a) the time cost of cryptographic operations at the tag side and (b) the time cost of data exchange between a reader and a tag, making it impossible to evaluate the total time cost for executing a protocol. Based on our experiments implemented on IAIK UHF tag emulators …

Opportunistic Routing In Wireless Sensor Networks Powered By Ambient Energy Harvesting, Zhi Ang Eu, Hwee-Pink Tan, Winston K. G. Seah Dec 2010

Opportunistic Routing In Wireless Sensor Networks Powered By Ambient Energy Harvesting, Zhi Ang Eu, Hwee-Pink Tan, Winston K. G. Seah

Research Collection School Of Computing and Information Systems

Energy consumption is an important issue in the design of wireless sensor networks (WSNs) which typically rely on portable energy sources like batteries for power. Recent advances in ambient energy harvesting technologies have made it possible for sensor nodes to be powered by ambient energy entirely without the use of batteries. However, since the energy harvesting process is stochastic, exact sleep-and-wakeup schedules cannot be determined in WSNs Powered solely using Ambient Energy Harvesters (WSN–HEAP). Therefore, many existing WSN routing protocols cannot be used in WSN–HEAP. In this paper, we design an opportunistic routing protocol (EHOR) for multi-hop WSN–HEAP. Unlike traditional …

A Multi-User Steganographic File System On Untrusted Shared Storage, Jin Han, Meng Pan, Debin Gao, Hwee Hwa Pang Dec 2010

A Multi-User Steganographic File System On Untrusted Shared Storage, Jin Han, Meng Pan, Debin Gao, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

Existing steganographic file systems enable a user to hide the existence of his secret data by claiming that they are (static) dummy data created during disk initialization. Such a claim is plausible if the adversary only sees the disk content at the point of attack. In a multi-user computing environment that employs untrusted shared storage, however, the adversary could have taken multiple snapshots of the disk content over time. Since the dummy data are static, the differences across snapshots thus disclose the locations of user data, and could even reveal the user passwords. In this paper, we introduce a Dummy-Relocatable …

The Amicus Curiae: Friends No More?, S. Chandra Mohan Dec 2010

The Amicus Curiae: Friends No More?, S. Chandra Mohan

Research Collection Yong Pung How School Of Law

A term commonly used in both common law and civil law jurisdictions and in domestic and international tribunals is the Latin term amicus curiae or a 'friend of the court'. Who is this friend of the court and what is his role in legal proceedings? Largely because of the remarkable manner in which this ancient institution has developed in different legal systems and been used differently even in countries sharing a common legal tradition, such as the United States and the Commonwealth countries, the important question is whether the amicus curiae can still be considered a 'friend' of any tribunal …

Topical Summarization Of Web Videos By Visual-Text Time-Dependent Alignment, Song Tan, Hung-Khoon Tan, Chong-Wah Ngo Dec 2010

Topical Summarization Of Web Videos By Visual-Text Time-Dependent Alignment, Song Tan, Hung-Khoon Tan, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Search engines are used to return a long list of hundreds or even thousands of videos in response to a query topic. Efficient navigation of videos becomes difficult and users often need to painstakingly explore the search list for a gist of the search result. This paper addresses the challenge of topical summarization by providing a timeline-based visualization of videos through matching of heterogeneous sources. To overcome the so called sparse-text problem of web videos, auxiliary information from Google context is exploited. Google Trends is used to predict the milestone events of a topic. Meanwhile, the typical scenes of web …

Optimized Algorithms For Predictive Range And Knn Queries On Moving Objects, Rui Zhang, H.V. Jagadish, Bing Tian Dai, Kotagiri Ramamohanarao Dec 2010

Optimized Algorithms For Predictive Range And Knn Queries On Moving Objects, Rui Zhang, H.V. Jagadish, Bing Tian Dai, Kotagiri Ramamohanarao

Research Collection School Of Computing and Information Systems

There have been many studies on management of moving objects recently. Most of them try to optimize the performance of predictive window queries. However, not much attention is paid to two other important query types: the predictive range query and the predictive k nearest neighbor query. In this article, we focus on these two types of queries. The novelty of our work mainly lies in the introduction of the Transformed Minkowski Sum, which can be used to determine whether a moving bounding rectangle intersects a moving circular query region. This enables us to use the traditional tree traversal algorithms to …

Evaluation Of Protein Backbone Alphabets : Using Predicted Local Structure For Fold Recognition, Kyong Jin Shim Dec 2010

Evaluation Of Protein Backbone Alphabets : Using Predicted Local Structure For Fold Recognition, Kyong Jin Shim

Research Collection School Of Computing and Information Systems

Optimally combining available information is one of the key challenges in knowledge-driven prediction techniques. In this study, we evaluate six Phi and Psi-based backbone alphabets. We show that the addition of predicted backbone conformations to SVM classifiers can improve fold recognition. Our experimental results show that the inclusion of predicted backbone conformations in our feature representation leads to higher overall accuracy compared to when using amino acid residues alone.

Our Country Right Or Wrong: A Pragmatic Response To Anti-Democratic Cultural Nationalism In China, Sor-Hoon Tan Dec 2010

Our Country Right Or Wrong: A Pragmatic Response To Anti-Democratic Cultural Nationalism In China, Sor-Hoon Tan

Research Collection School of Social Sciences

Since Deng Xiaoping came into power, China has been described as pragmatic in its approach to politics and development, and in the nineties there has been a revival of interest in Chinese cultural tradition. What is the relation between these two phenomena? Do they coexist, separately in mutual indifference, or in tension? Has there been constructive engagement, or at the very least does the potential for such engagement exist? More specifically, what roles, if any, do they play in China's quest for democracy? Does Dewey's pragmatism have any relevance to China in the twenty-first century? The issue of cultural tradition …
