Dtd-Miner: A Tool For Mining Dtds From Xml Documents, Moh Chuang Hue, Ee Peng Lim, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

XML documents are semistructured and the structure of the documents is embedded in the tags. Although XML documents can be accompanied by a DTD that defines the structure of the documents, the presence of a DTD is not mandatory. The difficulty in deriving the DTD for XML documents lies in the fact that DTDs are of different syntax as XML and that prior knowledge of the structure of the documents is required. In this paper, we introduce DTD-Miner, an automatic structure-mining tool for XML documents. Using a Web-based interface, the user will be able to submit a set of similarly …

A Model Of Relational Leadership: The Integration Of Trust And Leader-Member Exchange, Holly H. Brower, F. David Schoorman, Hwee Hoon Tan

Research Collection Lee Kong Chian School Of Business

This article presents a model of relational leadership based on a review of leader-member exchange (LMX) and interpersonal trust. This model asserts that the LMX relationship is built through interpersonal exchanges in which parties to the relationship evaluate the ability, benevolence, and integrity of each other. These perceptions, in turn, influence the behaviors predicted by LMX researchers. This integrated model of relational leadership provides insights into the dynamics of leader-subordinate relationships and resolves some of the inconsistencies in the LMX research without losing the richness and uniqueness of the exchange theory. A number of propositions for future research in relational …

Achieving Growth Through Corporate Partnerships And Joint Ventures: Will Singapore's Strategic Leap Into The Region Work?, Ravinder K. Zutshi, Wee Liang Tan

Research Collection Lee Kong Chian School Of Business

One of the characteristic features of the East Asian economic development strategy has been the interventionist role of the government in the economic sphere (Amsden 1989; Kwon 1994; Wade 1990; Zutshi and Gibbons 1998). Governments in East Asia have traditionally, worked closely with the private sector. As a result unique business systems embedded in networks and alliances have evolved in countries like Taiwan, Japan, Korea and Singapore (Hamilton and Biggard 1988). Singapore has attempted to extend this model of strategic cooperation beyond its borders into the region. Schein (1996) identifies a number of major development eras in the evolution of …

A New Statistic For Regression Transformation, Zhenlin Yang

Research Collection School Of Economics

A new statistic for testing a regression transformation is proposed based on a result of Yang (1999). This statistic is shown to be stable, having a null distribution almost independent of model type and parameter values, accurate and easy to implement. The statistic is of the Wald-type and thus is compared with the Wald statistic given by Lawrence (1987) in terms of size, null distribution and power using simulation. The simulation results show that the new statistic generally outperforms that of Lawrence.

Justifying Electronic Banking Network Expansion Using Real Option Pricing: An Empirical Illustration, Michel Benaroch, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

The application of real options analysis to information technology investment evaluation problems recently has been proposed in the IS literature (Chalasani et al. 1997; Dos Santos 1991; Kambil et al. 1993; Kumar 1996; Taudes 1998). The research reported on in this paper illustrates the value of applying real options analysis in the context of a case study involving the deployment of point-of-sale (POS) debit services by the Yankee 24 shared electronic banking network of New England. In the course of so doing, the paper also attempts to operationalize real options analysis concepts by examining claimed strengths of this analysis approach …

Re-Engineering Structures From Web Documents, Moh Chuang Hue, Ee Peng Lim, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

To realize a wide range of applications (including digital libraries) on the Web, a more structured way of accessing the Web is required and such requirement can be facilitated by the use of XML standard. In this paper, we propose a general framework for reverse engineering (or re-engineering) the underlying structures i.e.,the DTD from a collection of similarly structured XML documents when they share some common but unknown DTDs. The essential data structures and algorithms for the DTD generation have been delveloped and experiments on real Web collections have been conducted to demonstrate their feasibilty. In addition, we also proposed …

Multicast Internet Protocol, X. K. Wang, Robert H. Deng, Feng Bao

Research Collection School Of Computing and Information Systems

In this paper, we first review the existing IPv4 based multicast protocols and identify their shortcomings. We then proposed a new multicast protocol, called Multicast Internet Protocol (MIP), which is both scalable and flexible. The design principle of MIP is fundamentally different from the existing IPv4 based multicast protocols. The issues related to MIP routing and implementations are also studied in this paper.

Decision Support Methods In Diabetic Patient Management By Insulin Administration Neural Network Vs. Induction Methods For Knowledge Classification, B. V. Ambrosiadou, S. Vadera, Venky Shankaraman, D. Goulis, G. Gogou

Research Collection School Of Computing and Information Systems

Diabetes mellitus is now recognised as a major worldwide public health problem. At present, about 100 million people are registered as diabetic patients. Many clinical, social and economic problems occur as a consequence of insulin-dependent diabetes. Treatment attempts to prevent or delay complications by applying ‘optimal’ glycaemic control. Therefore, there is a continuous need for effective monitoring of the patient. Given the popularity of decision tree learning algorithms as well as neural networks for knowledge classification which is further used for decision support, this paper examines their relative merits by applying one algorithm from each family on a medical problem; …

Predictive Adaptive Resonance Theory And Knowledge Discovery In Databases, Ah-Hwee Tan, Hui-Shin Vivien Soon

Research Collection School Of Computing and Information Systems

This paper investigates the scalability of predictive Adaptive Resonance Theory (ART) networks for knowledge discovery in very large databases. Although predictive ART performs fast and incremental learning, the number of recognition categories or rules that it creates during learning may become substantially large and cause the learning speed to slow down. To tackle this problem, we introduce an on-line algorithm for evaluating and pruning categories during learning. Benchmark experiments on a large scale data set show that on-line pruning has been effective in reducing the number of the recognition categories and the time for convergence. Interestingly, the pruned networks also …

The Trusted General Manager And Unit Performance: Empirical Evidence Of A Competitive Advantage, James H. Davis, F. David Schoorman, Roger C. Mayer, Hwee Hoon Tan

Research Collection Lee Kong Chian School Of Business

Employee trust for the general manager is proposed as an internal organizational characteristic that provides a competitive advantage for the firm. This paper empirically examines the relationship between trust for a business unit's general manager and organizational performance. Trust was found to be significantly related to sales, profits and employee turnover in the restaurant industry. Managers who were either more or less trusted differed significantly in perceptions of their ability, benevolence and integrity.

Toward The Differentiation Of Trust In Supervisor And Trust In Organization, Hwee Hoon Tan, Christy S. F. Tan

Research Collection Lee Kong Chian School Of Business

Trust in supervisor and trust in organization are argued to be distinct but related constructs, each with its own set of antecedents and outcomes. Empirical field results supported the proposition. Although trust in supervisor and trust in organization were positively and significantly correlated, trust in supervisor was more strongly associated with proximal variables (ability, benevolence, and integrity of supervisor), whereas trust in organization was more strongly correlated with global variables (perceived organizational support and justice). This conclusion held despite the inclusion of proximal variables in the regression on trust in organization and the inclusion of global variables in the regression …

Laminar Entry Flow Of Herschel-Bulkley Fluids In A Circular Pipe, R. C. Gupta, Yibao Zhao

Research Collection Lee Kong Chian School Of Business

Fargie and Martin used an elegant approach to obtain the entry region flow of Newtonian fluids in a circular pipe. They combined the differential and integral momentum equation in such a way that elimination of pressure gradient leads to a closed form solution. In this paper we extend this procedure to study the laminar entry region flow of Herschel-Bulkley fluids in a circular pipe. The solution procedure involves certain approximations. Applicability of these approximations to Herschel-Bulkley fluids has been discussed and the flow description has been obtained for various values of the flow behavior index and the Herschel-Bulkley number. Results …

Virtual Auditing Agents: The Edgar Agent Challenge, Kay M. Nelson, Alex Kogan, Rajendra P. Srivastava, Miklos Vasarhelyi, Hai Lu

Research Collection School Of Accountancy

Intelligent agents can be used as agents of organizational change. This potential exists in the domain of accounting audit, where much of what is currently done manually in batch mode could be done continuously and on-line. We discuss the use of intelligent Internet agents as a way of changing and expanding audit practices in the virtual world. A quality/service framework is presented that suggests ways that accounting firms can evolve in this era of on-line opportunities. The EDGAR Agent is presented as an example of an intelligent Internet agent that gathers financial information. The challenges involved in the development of …

Load Sharing In Distributed Multimedia-On-Demand Systems, Y. C. Tay, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

Service providers have begun to offer multimedia-on-demand services to residential estates by installing isolated, small-scale multimedia servers at individual estates. Such an arrangement allows the service providers to operate without relying on a highspeed, large-capacity metropolitan area network, which is still not available in many countries. Unfortunately, installing isolated servers can incur very high server costs, as each server requires spare bandwidth to cope with fluctuations in user demand. The authors explore the feasibility of linking up several small multimedia servers to a (limited-capacity) network, and allowing servers with idle retrieval bandwidth to help out servers that are temporarily overloaded; …

Downsizing, Debürokratisierung Und Krisenmanagement: Neuere Entwicklungstendenzen In Malaysias Öffentlicher Verwaltung, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

Der Beitrag analysiert mit Blick auf die Asienkrise Entwicklungsaspekte und ausgewählte Strukturmerkmale der öffentlichen Verwaltung in Malaysia, an die nicht zuletzt im Rahmen des derzeitigen Krisenmanagements hohe Anforderungen hinsichtlich Effizienz, Professionalität und Kundenorientiertheit gestellt werden. Besonderes Interesse gilt den vor einigen Jahren eingeleiteten Reform- und Debürokratisierungsmaßnahmen, durch die die Leistungskraft der öffentlichen Verwaltung und der in ihr Tätigen erhöht werden soll. Der Beitrag verdeutlicht die Hintergründe der anhaltenden Restrukturierungsanstrengungen, zeigt interne Schwachstellen auf und untersucht, inwieweit die öffentliche Verwaltung in der Lage ist, die an sie gestellten Erwartungen einzulösen.

From Market Driven To Market Driving, Nirmalya Kumar, Lisa Scheer, Philip Kotler

Research Collection Lee Kong Chian School Of Business

Firms are constantly exhorted to become more market driven. However, our study of 25 pioneering companies (e.g. Body Shop, IKEA, Tetra Pak) whose success has been based on radical business innovation indicates that such companies are better described as market driving. While market driven processes are excellent in generating incremental innovation, they rarely produce the type of radical innovation which underlies market driving companies. Market driving companies, who are generally new entrants into an industry, gain a more sustainable competitive advantage by delivering a leap in customer value through a unique business system. Market driving strategies entail high risk, but …

Assessing Export Platforms: The Case Of Singapore, Kong Weng Ho, Hian Teck Hoon

Research Collection School Of Economics

The aim of this paper is to try to understand how Singapore was generally successful in its export promoting strategy. Historically, Singapore experimented with an import-substituting strategy in the first half of the sixties in anticipation of forming a common market with Malaysia and also briefly after its independence in 1965. The level of protection, however, was relatively low during its import-substituting phase.

Jotmail: A Voicemail Interface That Enables You To See What Was Said, Steve Whittaker, Richard C. Davis, Julia Hirschberg, Urs Muller

Research Collection School Of Computing and Information Systems

Voicemail is a pervasive, but under-researched tool for workplace communication. Despite potential advantages of voicemail over email, current phone-based voicemail UIs are highly problematic for users. We present a novel, Web-based, voicemail interface, Jotmail. The design was based on data from several studies of voicemail tasks and user strategies. The GUI has two main elements: (a) personal annotations that serve as a visual analogue to underlying speech; (b) automatically derived message header information. We evaluated Jotmail in an 8-week field trial, where people used it as their only means for accessing voicemail. Jotmail was successful in supporting most key voicemail …

On The Validity Of Digital Signatures, Jianying Zhou, Robert H. Deng

Research Collection School Of Computing and Information Systems

An important feature of digital signatures is to serve as non-repudiation evidence. To be eligible as non-repudiation evidence, a digital signature on an electronic document should remain valid until its expiry date which is specified by some non-repudiation policy. As signature keys may be compromised and the validity of signatures may become questionable, additional security mechanisms need to be imposed on digital signatures. This paper examines the mechanisms for maintaining the validity of digital signatures, and provides a guideline on the use of these mechanisms in various context of applications.

Enhancing Economic Cooperation: A Regional Arbitration Centre For Asean?, Pearlie Koh

Research Collection Yong Pung How School Of Law

Economic co-operation within ASEAN can be said to have seriously begun only at the beginning of the nineties. Prior to that, it was well known that, ASEAN as a co-operative grouping, had existed mainly with a political and strategic focus. It is with this focus that ASEAN managed to establish and maintain cohesiveness through the years despite the shaky beginnings of what has been described as a 'brittle alliance' borne of a common fear of communism. And it is with this focus that ASEAN, as a regional grouping, has generally been hailed as a success.

A Framework For Acquiring Domain Semantics And Knowledge For Database Integration, Roger Hsiang-Li Chiang, Ee Peng Lim, Veda C. Storey

Research Collection School Of Computing and Information Systems

Database integration research has traditionally focused on understanding integration issues from the schema and instance perspectives. As a result, database integration approaches tend to rely on a direct comparison of schema and instance elements. However, when the integration of heterogeneous databases is performed without considering the domain semantics and knowledge of local databases such as context information and requirement specifications, an incorrect integrated database may be produced. In this research, a framework for carrying out database integration tasks using the above knowledge is proposed. The framework provides a thorough foundation to: 1. analyze database integration issues from a broad scope, …

Research Collection School of Social Sciences

Patients remanded over a two-year period to Woodbridge Hospital by Court Order were studied retrospectively. Schizophrenia was the most common diagnosis, theft and robbery the most prevalent offences. Males greatly outnumbered females. There were important gender differences, with males tending to commit sexual offences and females, theft and mischief. Males were less likely to be acquainted with their victims but those who caused hurt were more likely to know their victims. Outrage of modesty and theft were more likely to be committed against strangers. The reconviction rate was 26%, with repeat offenders more likely to commit sexual offences and theft. …

Treatment Of Multi-Courts Jurisdiction Agreements, Seow Hon Tan

Research Collection Yong Pung How School Of Law

An increasingly popular manner of drafting jurisdiction clauses in cross-border contracts involves the selection of the courts of more than one jurisdiction. Traditionally, parties would submit all disputes to the courts of a particular country under an exclusive jurisdiction agreement or agree that the transaction is subject to a particular jurisdiction without intending to create an obligation to proceed there and nowhere else. Of late, the Singapore courts have encountered litigation over multi-courts jurisdiction agreements. A common form involves the naming of a particular court with one of the parties being given the option to proceed anywhere else.

Sources Of Work-Family Conflict: A Sino-U.S. Comparison Of The Effects Of Work And Family Demands, Nini Yang, Chao C. Chen, Jaepil Choi, Yimin Zou

Research Collection Lee Kong Chian School Of Business

Given differences in values about work and family time, it is hypothesized that Americans will experience greater family demand, which will have greater impact on work-family conflict, whereas the Chinese will experience greater work demand, which will have the greater impact on work-family conflict. The results of a survey of working men and women in the 2 countries generally support the hypotheses; however, work demand did not differ significantly between the 2 countries and did not have a greater effect than family demand on work-family conflict in China.

Singapore Management University Report To Stakeholders 2000 - 2001, Singapore Management University

Report to Stakeholders

It has been an extremely gratifying first year for SMU. From scratch, we saw a curriculum developed, a more than credible faculty assembled, a campus bloom from the ground in record time, and a small group of bright and very promising young individuals set the standard as the historic pioneer intake of students. How did we even begin to persuade sponsors or students to come on board with us? We had no track record, no alumni, not even an existing undergraduate population. Yet, industry support was unabashedly warm from the time Singapore’s third university was announced. First year application for …
