Foreword, Chandran Kukathas

Research Collection School of Social Sciences

Hayek's essay 'Why I am not a Concervative' first appeared in 1960 as the final chapter of his treatise, The Constitution of Liberty. Strictly speaking, it was not really a concluding chapter; it was presented as a 'postscript' to the main text-a text whose concern was to articulate and elaborate upon the fundamental principles of classical liberalism. In this postscript Hayek attempted a task which the main treatise did not take up: to explain how the principles of classical liberalism set it apart from the conservatism with which it seemed to have so much in common.

Electronic Branching Ratio Of The Lepton, R. Ammar, Manoj Thulasidas Jan 1992

Electronic Branching Ratio Of The Lepton, R. Ammar, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

Using data accumulated by the CLEO I detector operating at the Cornell Electron Storage Ring, we have measured the ratio R=Γ(τ→eν¯eντ)Γ1 where Γ1 is the τ decay rate to final states with one charged particle. We find R=0.2231±0.0044±0.0073 where the first error is statistical and the second is systematic. Together with the measured topological one-charged-particle branching fraction, this yields the branching fraction of the τ lepton to electrons, Be=0.192±0.004±0.006.

Good Faith In English Law, Howard Hunter Jan 1992

Good Faith In English Law, Howard Hunter

Research Collection Yong Pung How School Of Law

'Good faith' is a term often used but rarely defined or analysed with care. In this short volume O'Connor has undertaken a formidable task: the development of a general principle of good faith that is applicable throughout English law. He begins with a proposed definition and then proceeds through brief analyses of the good faith concept in six areas of the law (administrative law, contracts, company law, criminal law, torts, trusts and property). He makes a quick excursion across the Channel to consider the civil law approach to the principle of good faith and then concludes with a chapter devoted …

Knowledge-Based Systems Approach For Offshore Safety Training, B. S. Lee, Venky Shankararaman Dec 1991

Knowledge-Based Systems Approach For Offshore Safety Training, B. S. Lee, Venky Shankararaman

Research Collection School Of Computing and Information Systems

A number of training methods has been used within the offshore industry to impart safety knowledge and safe operating skills. In this paper a Knowledge-Based Safety Training architecture is proposed. The architecture uses both expert system and hypertext methods and is also applicable to plants other than offshore platforms. Special attention is given to the types of knowledge dealt with in safety training and how to represent this knowledge and teach it using various teaching strategies.

Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen Dec 1991

Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen

Research Collection Lee Kong Chian School Of Business

Many authors have identified the hazards of ignoring event-induced variance in event studies. To determine the practical extent of the problem, we simulate an event with stochastic effects. We find that when an event causes even minor increases in variance, the most commonly-used methods reject the null hypothesis of zero average abnormal return too frequently when it is true, although they are reasonably powerful when it is false. We demonstrate that a simple adjustment to the cross-sectional techniques produces appropriate rejection rates when the null is true and equally powerful tests when it is false.

Implementing Corruption Prevention Strategies Through Codes Of Conduct, Mark Findlay, Andrew Stewart Nov 1991

Implementing Corruption Prevention Strategies Through Codes Of Conduct, Mark Findlay, Andrew Stewart

Research Collection Yong Pung How School Of Law

The concept of a code of conduct, as it appears in corruption prevention strategies, could be viewed as rather misleading. While dealing with conduct in some preferred or preemptive sense, these frameworks for "guidelines" bear little resemblance to prescriptive legal codes.

The Manufacturing Contribution To Innovation, Arnoud De Meyer Oct 1991

The Manufacturing Contribution To Innovation, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

The description of the contribution of manufacturing to the innovation process is often limited to the task of providing the necessary information to enable the development function to create a design which is easy to manufacture, and to be instrumental in the fast ramp-up of the production process. Though these are important tasks, it is argued in this paper that there is a third aspect of manufacturing’s contribution to innovation, namely the creation of a manufacturing system which is favorable to product innovation. This goes far beyond the design of an appropriate production process, but requires the creation of a …

Individual Differences In Response To Consumer Promotions, Gwen Ortmeyer, James M. Lattin, David B. Montgomery Sep 1991

Individual Differences In Response To Consumer Promotions, Gwen Ortmeyer, James M. Lattin, David B. Montgomery

Research Collection Lee Kong Chian School Of Business

This research hypothesizes important individual differences in response to promotions and tests for them using a cross-sectional multinomial logit choice model. Our hypotheses suggest interactions between individual brand preference and the effects of current promotion and past promotional purchase. To test for these interactions, we introduce a new method of measuring brand preference from past purchase data. The new method seeks to incorporate competitive purchase conditions as modifiers to observed brand purchase behavior in estimating consumer brand preference. We account for heterogeneity in the cross-sectional model by using two measures of loyalty: one to capture differences across individuals and one …

Connectionist Expert System With Adaptive Learning Capability, B. T. Low, Hochung Lui, Ah-Hwee Tan, Hoonheng Teh Jun 1991

Connectionist Expert System With Adaptive Learning Capability, B. T. Low, Hochung Lui, Ah-Hwee Tan, Hoonheng Teh

Research Collection School Of Computing and Information Systems

A neural network expert system called adaptive connectionist expert system (ACES) which will learn adaptively from past experience is described. ACES is based on the neural logic network, which is capable of doing both pattern processing and logical inferencing. The authors discuss two strategies, pattern matching ACES and rule inferencing ACES. The pattern matching ACES makes use of past examples to construct its neural logic network and fine-tunes itself adaptively during its use by further examples supplied. The rule inferencing ACES conceptualizes new rules based on the frequencies of use on the rule-based neural logic network. A new rule could …

Interpreting And Responding To Strategic Issues: The Impact Of National Culture, Susan C. Schneider, Arnoud De Meyer May 1991

Interpreting And Responding To Strategic Issues: The Impact Of National Culture, Susan C. Schneider, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

Perceptions of environmental uncertainty and organizational control influence strategic behavior. As national culture influences these perceptions we expect to find cultural differences in interpretation and response to strategic issues. Given a case describing an issue concerning deregulation of the U.S. banking industry, managers completed questionnaires rating interpretations and responses to that issue. National culture was found to influence interpretation and responses. In particular, Latin European managers when compared with other managers were more likely to interpret the issue as a crisis and as a threat. Latin Europeans were also more likely to recommend proactive behavior. This study indicates that different …

An Efficient Semantic Query Optimization Algorithm, Hwee Hwa Pang, Hongjun Lu, Beng Chin Lu Apr 1991

An Efficient Semantic Query Optimization Algorithm, Hwee Hwa Pang, Hongjun Lu, Beng Chin Lu

Research Collection School Of Computing and Information Systems

An efficient semantic query optimization algorithm is proposed, in which all possible transformations are tentatively applied to the query. Instead of physically modifying the query, the transformation process classifies the predicates into imperative, optional or redundant. At the end of the transformation process, all the imperative predicates are retained while the redundant predicates are eliminated. Optional predicates are retrained or discarded based on the estimated cost/benefit of retaining them. The issue of the grouping of semantic constraints to reduce the overhead of retrieving constraints and checking whether each constraint is relevant to the current query is also addressed. Based on …

Exclusive And Inclusive Semileptonic Decays Of B Mesons To D Mesons, R. Fulton, M. Thulasidas Jan 1991

Exclusive And Inclusive Semileptonic Decays Of B Mesons To D Mesons, R. Fulton, M. Thulasidas

Research Collection School Of Computing and Information Systems

We report new measurements of the branching fractions B ( B − → D 0 l − ¯ ν ) , B ( ¯ B 0 → D + l − ¯ ν ) , and B ( B − → D * 0 l − ¯ ν ) . Combining these results with our previous measurement of B ( ¯ B 0 → D * + l − ¯ ν ) , we find that the ratio of semileptonic widths for final states with a vector meson and pseudoscalar meson is ( 2.6 + 1.1 + 1.0 − 0.6 …

Fuzzy Neural Logic Network And Its Learning Algorithms, Fiona Fui-Hoon Nah, Nah Fiona Jan 1991

Fuzzy Neural Logic Network And Its Learning Algorithms, Fiona Fui-Hoon Nah, Nah Fiona

Research Collection School Of Computing and Information Systems

The paper introduces the basic features of fuzzy neural logic network. Each fuzzy neural logic network model is trained from a set of knowledge in the form of examples using one of the three learning algorithms introduced. These three learning algorithms are the delta rule controlled learning algorithm and two mathematical construction algorithms, namely, the local learning method and the global learning method. Once the fuzzy neural logic network model is constructed, it is ready to accept any unknown input from the user. With a low percentage of mismatched features, output solution can be obtained.

Inclusive Production Of The Charmed Baryon C+ From E+E- Annihilations At S=10.55 Gev, P. Avery, Manoj Thulasidas Jan 1991

Inclusive Production Of The Charmed Baryon C+ From E+E- Annihilations At S=10.55 Gev, P. Avery, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

We report results on inclusive production of the charmed baryon Λc+ from e+e− annihilations at √s=10.5 GeV. Measurements are presented of the inclusive cross section times branching fraction for the continuum production of Λc+ as observed in six different decay modes, and of a new, improved value of the Λc+ mass. The inclusive cross section times the branching fraction into pK−π+ is measured to be 10.0±1.5±1.5 pb summed over all xp. The branching fractions of Λc+ into p¯K0, p¯K0π+π−, Λπ+, Λπ+π−π+, and Ξ−K+π+ relative to that into pK−π+ are measured to be 0.44±0.07±0.05, 0.43±0.12±0.04, 0.18±0.03±0.03, 0.65±0.11±0.12, and 0.15±0.04±0.03, respectively.

The Fraternal Conceit: Individualist Versus Collectivist Ideas Of Community, Chandran Kukathas Jan 1991

The Fraternal Conceit: Individualist Versus Collectivist Ideas Of Community, Chandran Kukathas

Research Collection School of Social Sciences

In the modern world countless minorities press separate claims for recognition by their fellow countrymen, by their states and, in some cases, by the world. Many of these groups, such as the Australian Aborigines and New Zealand Maoris, describe themselves as indigenous peoples, while others identify themselves simply as ethnic or cultural minorities with legitimate grievances. The various demands made by such groups leave us in no doubt that there is a political problem. But there is also an important philosophical question to be addressed: a question about the terms of civil association. The modern world has seen two great …

The Hong Kong Jury: A Microcosm Of Society?, Peter Duff, Mark Findlay, Carla Howarth Oct 1990

The Hong Kong Jury: A Microcosm Of Society?, Peter Duff, Mark Findlay, Carla Howarth

Research Collection Yong Pung How School Of Law

The claim that the jury is a randomly chosen and representative sample of community is an important part of the ideology which currently underpins the institution. Supporters of the jury argue that both its impartiality and its independence from the State are bolstered by the fact that it represents a randomly selected cross-section of the populace. In most common law jurisdictions where the jury operates, various steps have been taken over recent years in order preserve and strengthen the perception of the jury as a "microcosm of democratic society". For example, in England the property qualification for jurors was removed …

How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer Jul 1990

How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

The large majority of modern production companies have at their disposal a multitude of computer systems. The immediate challenge for these companies consists of integrating these computer systems and databases. How will one arrive at this integration? On the basis of a questionnaire administered in 1985, 1986 and 1987 among a group of large European manufacturers, one comes to the conclusion that this integration is one of the immediate priorities for this group of companies. They do not intend to implement turnkey systems. but instead will integrate the different databases and computer systems gradually. One can see emerging islands of …

Reception Of English Law In Singapore: Problems And Proposed Solutions, Andrew B.L. Phang Jan 1990

Reception Of English Law In Singapore: Problems And Proposed Solutions, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

The problems pertaining to the reception of English law in Singapore are both numerous and complex. The academic literature generated in the local sphere alone is relatively large. It must, however, be conceded that, from apractical point of view, there has been very little interest or at least discussion. One cannot, of course, be sure about this observation, save for the very strong indication that takes the form of the overwhelming lack of litigation in the area, thus rendering it merely (so it appears) an academic monopoly. It should, however, be pointed out that this rather phlegmatic approach in practice …

A Commentary On Professor Fisher’S Thesis: Ideology, Religion, Private Property And The Supreme Court 1987-88, Howard Hunter Jan 1990

A Commentary On Professor Fisher’S Thesis: Ideology, Religion, Private Property And The Supreme Court 1987-88, Howard Hunter

Research Collection Yong Pung How School Of Law

The most important lessons to be learned from Professor Fisher's paper are that the ideologies central to American law have roots in religious thought and that the influence of ideologies can be found throughout American law, perhaps most especially in judicial decisions. To these lessons we can add a third: the ideologies embodied in judicial decisions concerning private property in the period from the American Revolution to the Civil War are still with us. Three recent decisions of the United States Supreme Court' illustrate the continuing importance of the constitutional and ideological protection of private property, while offering an interesting …

Trellis-Coded Multidimensional Phase Modulation, S. S. Pietrobon, Robert H. Deng Jan 1990

Trellis-Coded Multidimensional Phase Modulation, S. S. Pietrobon, Robert H. Deng

Research Collection School Of Computing and Information Systems

A 2L-dimensional multiple phase-shift keyed (L×MPSK) signal set is obtained by forming the Cartesian product of L two-dimensional MPSK signal sets. A systematic approach to partitioning L×MPSK signal sets that is based on block coding is used. An encoder system approach is developed. It incorporates the design of a differential precoder, a systematic convolutional encoder, and a signal set mapper. Trellis-coded L×4PSK, L×8PSK, and L×16PSK modulation schemes are found for 1⩽L⩽4 and a variety of code rates and decoder complexities, many of which are fully transparent to discrete phase rotations of the signal set. The new codes achieve asymptotic coding …

Jurisprudential Oaks From Mythical Acorns: The Hart‐Dworkin Debate Revisited, Andrew B.L. Phang Jan 1990

Jurisprudential Oaks From Mythical Acorns: The Hart‐Dworkin Debate Revisited, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

This article attempts to demonstrate, via the famous Hart-Dworkin debate on the nature and functions of judicial discretion, that substantial jurisprudential disputes as well as theories can, and do, arise from misconceived critiques, whether intended or otherwise. It also seeks to show that, whilst Dworkin's initial critique of Hart was misconceived, his theory of adjudication that arose as a result of responses to his initial views is a positive contribution to learning, although I argue that Dworkin's views are not, in the final analysis, sufficiently persuasive to constitute a radical departure from Hart's own views.

Icac And The Community, Mark Findlay Nov 1989

Icac And The Community, Mark Findlay

Research Collection Yong Pung How School Of Law

Recently the language of 'community' has been widely used in the official discourse of criminal justice administration in Australia, in an obvious effort to legitimate new developments away from more traditional crime control. Commentators are now asking, why all this 'community speak' about policing, mediation, and corrections? As regards the 'community' perspective of anti-corruption initiatives, it is an attempt to transfer to the new institutions and processes some of the more positive implications which are assumed to flow from community allegiance.

High Rate Concatenated Coding Systems Using Multidimensional Bandwidth Efficient Inner Codes, Robert H. Deng, Daniel J. Jr. Costello Oct 1989

High Rate Concatenated Coding Systems Using Multidimensional Bandwidth Efficient Inner Codes, Robert H. Deng, Daniel J. Jr. Costello

Research Collection School Of Computing and Information Systems

A concatenated coding system using two-dimensional trellis-coded MPSK inner codes and Reed-Solomon outer codes for application in high-speed satellite communication systems was proposed previously by the authors (ibid., vol.37, no.5, p.420-7, May 1989). The authors extend their results to systems using symbol-oriented, multidimensional, trellis-coded MPSK inner codes. The concatenated coding systems are divided into two classes according to their achievable effective information rates. The first class uses multidimensional trellis-coded 8-PSK inner codes and achieves effective information rates around 1 b/dimension (spectral efficiency 2 b/s/Hz). The second class employs multidimensional trellis-coded 16-PSK inner codes and provides effective information rates around 1.5 …

A Direct Test Of Rock's Model Of The Pricing Of Unseasoned Issues, Francis Koh, Terry Walter Aug 1989

A Direct Test Of Rock's Model Of The Pricing Of Unseasoned Issues, Francis Koh, Terry Walter

Research Collection Lee Kong Chian School Of Business

Unique data availability and institutional arrangements for new issues in Singapore allow a direct test of the empirical implications of Rock's model of pricing unseasoned new issues. Our empirical results are consistent with the model. Specifically we find that the unseasoned new issues' anomaly disappears when the rationing associated with new issues is incorporated into the analysis. The winner's curse is evident in allocation patterns used in Singapore.

Parity Retransmission Hybrid Arq Using Rate 1/2 Convolutional Codes On A Nonstationary Channel, L. R. Lugand, D. J. Costello, Jr., Robert H. Deng Jul 1989

Parity Retransmission Hybrid Arq Using Rate 1/2 Convolutional Codes On A Nonstationary Channel, L. R. Lugand, D. J. Costello, Jr., Robert H. Deng

Research Collection School Of Computing and Information Systems

A parity retransmission hybrid automatic repeat request (ARQ) scheme is proposed which uses rate 1/2 convolutional codes and Viterbi decoding. A protocol is described which is capable of achieving higher throughputs than previously proposed parity retransmission schemes. The performance analysis is based on a two-state Markov model of a nonstationary channel. This model constitutes a first approximation to a nonstationary channel. The two-state channel model is used to analyze the throughput and undetected error probability of the protocol presented when the receiver has both an infinite and a finite buffer size. It is shown that the throughput improves as the …

Competitive Groups As Cognitive Communities: The Case Of The Scottish Knitwear Manufacturers, Joseph F. Porac, Howard Thomas, Charles Baden-Fuller Jul 1989

Competitive Groups As Cognitive Communities: The Case Of The Scottish Knitwear Manufacturers, Joseph F. Porac, Howard Thomas, Charles Baden-Fuller

Research Collection Lee Kong Chian School Of Business

This article explores how the mental models of organizational strategists determine perceptions of competing organizations and responses to competitive conditions. We first outline a cognitive perspective for discussing competitive strategy, and then use this framework to analyse the particular case of the Scottish knitwear industry. We show how the structure of that industry both determines and is determined by managerial perceptions of the environment. We conclude by drawing out a few general implications of our framework for research and theory on competitive strategy.

High Rate Concatenated Coding Systems Using Bandwidth Efficient Trellis Inner Codes, Robert H. Deng, D. J. Costello, Jr.

Research Collection School Of Computing and Information Systems

High-rate concatenated coding systems with bandwidth-efficient trellis inner codes and Reed-Solomon (RS) outer codes are investigated for application in high-speed satellite communication systems. Two concatenated coding schemes are proposed. In one the inner code is decoded with soft-decision Viterbi decoding, and the outer RS code performs error-correction-only decoding (decoding without side information). In the other the inner code is decoded with a modified Viterbi algorithm, which produces reliability information along with the decoded output. In this algorithm, path metrics are used to estimate the entire information sequence, whereas branch metrics are used to provide reliability information on the decoded sequence. …

Measuring The Unjust Enrichment In A Restitution, Howard Hunter Mar 1989

Measuring The Unjust Enrichment In A Restitution, Howard Hunter

Research Collection Yong Pung How School Of Law

Unjust enrichment is a theme common to most restitution cases in the United States. The theory of recovery is based on a justice principle the disgorgement of an unfairly obtained gain. The goal, in general, is to require the defendant to give up his gain rather than to compensate the plaintiff for a loss, as in a tort case, or to substitute damages for an unfulfilled expectancy, as in a contract case. This paper examines some of the issues that surround the measurement of the unjust enrichment and the defendant's liability. There are a number of straightforward rules for the …
