Study Of Fermion Pair Production In E+E- Collisions At 130-183 Gev, R. Barate, M. Thulasidas Jan 2000

Study Of Fermion Pair Production In E+E- Collisions At 130-183 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The cross sections and forward-backward asymmetries of hadronic and leptonic events produced in e+e−e+e− collisions at centre-of-mass energies from 130 to 183 GeV are presented. Results for e+e−e+e−, μ+μ−μ+μ−, τ+τ−τ+τ−, qq¯qq¯, bb¯bb¯ and cc¯cc¯ production show no significant deviation from the Standard Model predictions. This enables constraints to be set upon physics beyond the Standard Model such as four-fermion contact interactions, leptoquarks, Z′Z′ bosons and R-parity violating squarks and sneutrinos. Limits on the energy scale ΛΛ of e+e−ff¯e+e−ff¯ contact interactions are typically in the range from 2 to 10 TeV. Limits on R-parity violating sneutrinos reach masses of a few …

Evaluating A Change To Seminar-Style Teaching, Kirsten Anker, Catherine Dauvergne, Mark Findlay, Jenni Millbank Jan 2000

Evaluating A Change To Seminar-Style Teaching, Kirsten Anker, Catherine Dauvergne, Mark Findlay, Jenni Millbank

Research Collection Yong Pung How School Of Law

While the use of small to medium-sized seminar-style groups has long been a feature of some Australian law faculties, such as the University of New South Wales, it is a recent innovation in others, including the University of Western Australia and the University of Adelaide. In March 1996 the Faculty of Law at the University of Sydney made a decision to move from a traditional lecture and tutorial structure to seminar-style classes of limited size. This article discusses the reasons for the move away from a traditional lecture/ tutorial format to an interactive seminar-style model of teaching. The paper explains …

The Singapore Legal System – History, Theory And Practice, Andrew B.L. Phang Jan 2000

The Singapore Legal System – History, Theory And Practice, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

Law is central to order and stability and, without order and stability, societal as well as economic viability (let alone progress) are impossible The alternative is 'rule of man', and all the dangers of fallibility and (consequently) despotism that that entails. One central difficulty has, of course, been the maintenance of the argument that law is consonant with objective truth for if the law does not in fact possess this quality, then the 'rule of law' turns out to be the 'rule of man' after all. However, it is difficult, on rational grounds at least, to reject the concept of …

Contract Law At Century's End: Some Personal Reflections, Andrew B.L. Phang Jan 2000

Contract Law At Century's End: Some Personal Reflections, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

As we approach the end of the second millennium, the common law of contract-transplanted via colonialism into many lands and climes-has indeed flourished. It has certainly developed apace in the land of its origin, England, but has also evolved in distinct directions elsewhere, particularly in Australia and New Zealand.2 But this development is simply part of a continuous process and a great many interesting issues remain to be considered at the commencement of the next millennium and beyond. This is due, in part, to the very diversity that has been briefly alluded to. However, even on a more general level, …

Some Remarks On Fair Exchange Protocol, Jianying Zhou, Robert H. Deng, Feng Bao Jan 2000

Some Remarks On Fair Exchange Protocol, Jianying Zhou, Robert H. Deng, Feng Bao

Research Collection School Of Computing and Information Systems

Fair exchange turns out to be an increasingly important topic due to the rapid growth of electronic commerce. An exchange is deemed to be fair if at the end of exchange, either each party receives the expected item or neither party receives any useful information about the other’s item. Several protocols for fair exchange have been proposed in recent years. In this paper, we first examine a newly published fair exchange protocol and point out its flaws and weaknesses. We then put forward a more efficient and secure protocol and give an informal analysis.

An Integrated Data Mining System To Automate Discovery, Cecil Chua, Roger Hsiang-Li Chiang, Ee Peng Lim Jan 2000

An Integrated Data Mining System To Automate Discovery, Cecil Chua, Roger Hsiang-Li Chiang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Many data analysts require tools which can integrate their database management packages (e.g. Microsoft Access) with their data analysis ones (e.g. SAS, SPSS), and provide guidance for the selection of appropriate mining algorithms. In addition, the analysts need to extract and validate statistical results to facilitate data mining. In this paper, we describe an integrated data mining system called the Linear Correlation Discovery System (LCDS) that meets the above requirement. LCDS consists of four major sub-components, two of which, the selection assistant and the statistics coupler, are discussed in this paper. The former examines the schema and instances to determine …

The Integration Of Relationship Instances From Heterogeneous Databases, Ee Peng Lim, Roger Hsiang-Li Chiang Jan 2000

The Integration Of Relationship Instances From Heterogeneous Databases, Ee Peng Lim, Roger Hsiang-Li Chiang

Research Collection School Of Computing and Information Systems

In the process of integrating legacy databases, one has to resolve inter-database conflicts at both the schema and instance levels. In this paper, we discuss relationship conflicts as a special type of conflicts to be resolved during the database integration. Relationships are properties that relate real world objects. So far, most inter-database relationship conflicts are addressed at the schema-level by various schema integration techniques. However, instance-level relationship conflicts are largely neglected. This paper therefore investigates the causes of instance-level relationship conflicts and proposes a taxonomy for classifying instance-level relationship conflicts. In addition, we develop a systematic process to resolve instance-level …

The Multi– Mode Resource– Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen Dec 1999

The Multi– Mode Resource– Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen

Research Collection Lee Kong Chian School Of Business

In this paper, we tackle the challenging problem of scheduling activities to minimize the project duration, in which the activities (a) are subject to generalized precedence relations, (b) require units of multiple renewable, non-renewable and doubly constrained resources for which a limited availability is imposed, and (c) can be performed in one of several different ways, reflected in multiple activity scenarios or modes. These multiple modes give rise to several kinds of tradeoffs (time/resource, time/cost and resource/resource trade-offs) which allow for a more effcient allocation and use of resources. We present a local search-based solution methodology which is able to …

A Different Look At Assessment Centers: Views Of Assessment Center Users, Filip Lievens, Hans Goemaere Dec 1999

A Different Look At Assessment Centers: Views Of Assessment Center Users, Filip Lievens, Hans Goemaere

Research Collection Lee Kong Chian School Of Business

This study aims to shed light on possible problems of assessment center users and designers when developing and implementing assessment centers. Semi-structured interviews with a representative sample of assessment center users in Flanders revealed that, besides a large variability in assessment center practice, practitioners experience problems with dimension selection and definition, exercise design, line/staff managers as assessors, distinguishing between observation and evaluation, and with the content of assessor training programs. Solutions for these problems are suggested.

Organizing Culture: Leader Roles, Behaviors, And Reinforcement Mechanisms, Gerard George, Randall G. Sleeth, Mark A. Siders Dec 1999

Organizing Culture: Leader Roles, Behaviors, And Reinforcement Mechanisms, Gerard George, Randall G. Sleeth, Mark A. Siders

Research Collection Lee Kong Chian School Of Business

Organizational leaders provide the primary impetus in defining, forming and shaping corporate culture. Leadership literature emphasizes on the leader's role in "articulating a vision" and the leader's pivotal role in establishing culture by setting objectives and then removing hurdles by smoothing the path for attaining those objectives. The model of corporate culture transmission focuses on behaviors that corporate leaders employ to create, communicate and manage corporate culture. However, the model does not emphasize interpretation and identification with leader behaviors in ways that would cause members to embrace the leader's values and beliefs. Improved focus over two decades does not yet …

The Persistent Competitive Advantage Of Traditional Food Retailers In Asia: Wet Markets' Continued Dominance In Hong Kong, Arieh Goldman, Robert E. Krider, Seshan Ramaswami Dec 1999

The Persistent Competitive Advantage Of Traditional Food Retailers In Asia: Wet Markets' Continued Dominance In Hong Kong, Arieh Goldman, Robert E. Krider, Seshan Ramaswami

Research Collection Lee Kong Chian School Of Business

The focus of this article is the persistent continued strength of wet markets in Hong Kong and the weakness of supermarkets in the fresh food area. This phenomenon is surprising because, based on the experiences in North America and Western Europe and given the well-developed economy of Hong Kong, one would have expected supermarkets to dominate fresh food retailing and wet markets to be in retreat. In this article, the authors explain the reasons for the continued dominance of wet markets. They argue that consumers’shopping and consumption culture, the effectiveness of wet markets in handling consumers’needs, and the appropriateness of …

Measuring Information Quality Of Web Site: Development Of Instrument, P. Katerattanakul, Keng Siau Dec 1999

Measuring Information Quality Of Web Site: Development Of Instrument, P. Katerattanakul, Keng Siau

Research Collection School Of Computing and Information Systems

Web sites have been extensively used to provide information to consumers. While practitioners and researchers have proposed different criteria for effective Web site design based on common sense, intuition, and rules-ofthumb, effective Web site design focusing on the quality of the information it provides has rarely been studied. In this research, we propose a framework and develop an instrument to measure the information quality of individual or personal Web sites. The theoretical foundation of this research is the information quality framework. The proposed framework and instrument were tested in an individual or personal Web site context.

An Investigation Of Price Discovery In Informationally-Linked Markets: Equity Trading In Malaysia And Singapore, David K. Ding, Frederick H. Harris, Sie Ting Lau, Thomas H. Mclnish

Research Collection Lee Kong Chian School Of Business

Using transactions data for the Kuala Lumpur Stock Exchange and the Stock Exchange of Singapore (SES) for a major Malaysian conglomerate, Sime Darby Berhad, and intraday exchange rate data, we investigate whether and to what extent each exchange contributes to price discovery. Results indicate that the price series are cointegrated. The raw data appear to indicate the presence of arbitrage opportunities, but none exist after taking exchange rate changes into account. Using the common long-memory factors of Gonzalo and Granger (1995, Journal of Business and Economic Statistics 13, 1-9), we show that while the majority of the price discovery (approximately …

Multivariate Density Forecast Evaluation And Calibration In Financial Risk Management: High-Frequency Returns On Foreign Exchange, Francis X. Diebold, Jinyong Hahn, Anthony S. Tay Nov 1999

Multivariate Density Forecast Evaluation And Calibration In Financial Risk Management: High-Frequency Returns On Foreign Exchange, Francis X. Diebold, Jinyong Hahn, Anthony S. Tay

Research Collection School Of Economics

We provide a framework for evaluating and improving multivariate density forecasts. Among other things, the multivariate framework lets us evaluate the adequacy of density forecasts involving cross-variable interactions, such as time-varying conditional correlations. We also provide conditions under which a technique of density forecast calibration can be used to improve deficient density forecasts, and we show how the calibration method can be used to generate good density forecasts from econometric models, even when the conditional density is unknown. Finally, motivated by recent advances in financial risk management, we provide a detailed application to multivariate high-frequency exchange rate density forecasts. © …

Research Collection School Of Computing and Information Systems

MPEG-4, under the auspices of the ISO, is specifying tools to enable object-based audio-visual presentations [3]. These include tools to encode individual objects, compose presentations with objects, store these object-based presentations and access these presentations in a distributed manner over networks. The main distinguishing feature of object-based audio-visual presentations is the scene composition at the user terminal. The objects that are part of a scene are composed and displayed at the user end as opposed to encoding the composed scenes as is done in the case of MPEG-2. Such object-based representation and presentation has several benefits including compression efficiency and …

Using Strategic Partnerships To Create A Sustainable Competitive Position For Hi-Tech Start-Up Firms, Arnoud De Meyer Oct 1999

Using Strategic Partnerships To Create A Sustainable Competitive Position For Hi-Tech Start-Up Firms, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

In most cases these companies chose or were forced to engage in a technology partnership in order to develop and survive. As one would expect, some of these partnerships succeeded whilst others failed. With hindsight it occurred to the author that success or failure was not necessarily a random event, or idiosyncratic to one particular company, but that there seemed to be a pattern. Some partnerships failed because they were a strategic misfit, others probably because they were badly implemented. Based on these clinical case studies, The author addresses these questions: when and under what conditions a partnership is needed; …

Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey Oct 1999

Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey

Research Collection Lee Kong Chian School Of Business

The authors develop a framework for understanding the integration of marketing with business processes and shareholder value. The framework redefines marketing phenomena as embedded in three core business processes that generate value for customers-product development management, supply chain management, and customer relationship management-which in turn creates shareholder value. Such a conceptualization of marketing has the potential to introduce dramatic shifts in the scope, content, and influence of marketing in the organization. The authors highlight the implications of an organizationally embedded view of marketing for the future of marketing theory and practice.

Manufacturing Strategy And New Venture Performance: A Comparison Of Independent And Corporate Ventures In The Biotechnology Industry, Shaker A. Zahra, Gerard George

Research Collection Lee Kong Chian School Of Business

Little empirical research has compared the manufacturing strategies of corporate and independent new ventures. This study explores these differences with data from the young, science-based biotechnology industry, and examines the performance effects of manufacturing strategy variables including scope, competitive thrust, and capabilities. The results show that the corporate and independent biotechnology new ventures pursue significantly different manufacturing strategies, and that different dimensions of manufacturing strategies affect the performance of corporate vs. independent ventures quite differently.

Is The Term Premium A Risk Premium?, Louis H. Ederington, Jeremy C. Goh Sep 1999

Is The Term Premium A Risk Premium?, Louis H. Ederington, Jeremy C. Goh

Research Collection Lee Kong Chian School Of Business

This paper explores whether excess holding period returns on long vis-a-vis short-term securities behave in a manner that is consistent with (1) market efficiency, (2) the time-varying-term-premium variant of the expectations hypothesis, and (3) theories of the term premium that view it as a reward for risk bearing. Both traditional and modern theories of the term premium imply that it should evolve fairly slowly over time as attitudes toward risk and/or perceived covariances with wealth or consumption change. This implies that this period's term premium should have some predictive ability for next period's. However, we find that this quarter's ex-post …

Internet, World Wide Web, And Creativity, Keng Siau

Research Collection School Of Computing and Information Systems

The growth of the Internet has been the most astonishing technological and social phenomenon of the last decade of this century. In 1990 only a few academics had heard of it; now, more than 50 million people use it. By the turn of the century, that figure could be 100–200 million. So far, the network's only constant has been that the number of new users has doubled almost every 12–18 months. Most organizations have or will soon have Internet access. The popularity of Internet provides a tremendous opportunity for individuals and organizations to explore its features and services for electronic …

Design Approaches To Model-Based Simulation In Intelligent Computer Assisted Instruction, Bjoern Helfesrieder, Venky Shankararaman

Research Collection School Of Computing and Information Systems

Model-based simulation systems have been created in various fields of engineering to train personnel or students in operation, maintenance and troubleshooting of complex devices and systems. A review of literature indicates a lack of good overviews of the approaches to system design of model-based training simulations in Intelligent Computer Assisted Instruction (ICAI). Though single systems have to some extent been evaluated with regard to their performance, an organised evaluation, especially a comparative evaluation of the systems that have been created within the field is lacking. To be able to successfully conduct an in-depth review under these conditions, we concentrate and …

Locating Web Information Using Web Checkpoints, Aik Kee Luah, Wee-Keong Ng, Ee Peng Lim, Wee Peng Lee, Yinyan Cao

Research Collection School Of Computing and Information Systems

Conventional search engines locate information by letting users establish a single web checkpoint1. By specifying one or more keywords, users direct search engines to return a set of documents that contain those keywords. From the documents (links) returned by search engines, user proceed to further probe the WWW from there. Hence, these initial set of documents (contingent upon the occurrence of keyword(s)) serve as a web checkpoint. Generally, these links are numerous and may not result in much fruitful searches. By establishing multiple web checkpoints, a richer and controllable search procedure can be constructed to obtain more relevant Web information. …

Non-Repudiation In An Agent-Based E-Commerce System, Chin Chuan Liew, Wee-Keong Ng, Ee Peng Lim, Beng Suang Tan, Kok-Leong Ong Sep 1999

Non-Repudiation In An Agent-Based E-Commerce System, Chin Chuan Liew, Wee-Keong Ng, Ee Peng Lim, Beng Suang Tan, Kok-Leong Ong

Research Collection School Of Computing and Information Systems

Abecos is an agent-based e-commerce system under development at the Nanyang Technological University. A key factor in making this system usable in practice is strict security controls. One aspect of security is the provision of non-repudiation services. As protocols for non-repudiation have focused on -message non-repudiation, its adaptation to afford non-repudiation in a communication session for two agents in Abecos is inefficient. In this work, we investigate and propose a protocol for enforcing non-repudiation in a session. The protocol is believed to be applicable in any e-commerce system; agent- or not agent-based.

Theory And Research In Strategic Management: Swings Of A Pendulum, Robert E. Hoskisson, William P. Wan, Daphne W. Yiu, William A. Hitt

Research Collection Lee Kong Chian School Of Business

The development of the field of strategic management within the last two decades has been dramatic. While its roots have been in a more applied area, often referred to as business policy, the current field of strategic management is strongly theory based, with substantial empirical research, and is eclectic in nature. This review of the development of the field and its current position examines the field’s early development and the primary theoretical and methodological bases through its history. Early developments include Chandler’s (1962) Strategy and Structure and Ansoff’s (1965) Corporate Strategy. These early works took on a contingency perspective (fit …
