Bargaining And Competition Revisited, Takashi Kunimoto, Roberto Serrano Mar 2004

Bargaining And Competition Revisited, Takashi Kunimoto, Roberto Serrano

Research Collection School Of Economics

We show the robustness of the Walrasian result obtained in models of bargaining in pairwise meetings. Restricting trade to take place only in pairs, most of the assumptions made in the literature are dispensed with. These include assumptions on preferences (differentiability, monotonicity, strict concavity, bounded curvature), on the set of agents (dispersed characteristics) or on the consumption set (allowing only divisible goods).

Prediction Of Rna-Binding Proteins From Primary Sequence By A Support Vector Machine Approach., Lian Yi Han, Cong Zhong Cai, Siaw Ling Lo, Maxey Chung, Yu Zong Chen Mar 2004

Prediction Of Rna-Binding Proteins From Primary Sequence By A Support Vector Machine Approach., Lian Yi Han, Cong Zhong Cai, Siaw Ling Lo, Maxey Chung, Yu Zong Chen

Research Collection School Of Computing and Information Systems

Elucidation of the interaction of proteins with different molecules is of significance in the understanding of cellular processes. Computational methods have been developed for the prediction of protein-protein interactions. But insufficient attention has been paid to the prediction of protein-RNA interactions, which play central roles in regulating gene expression and certain RNA-mediated enzymatic processes. This work explored the use of a machine learning method, support vector machines (SVM), for the prediction of RNA-binding proteins directly from their primary sequence. Based on the knowledge of known RNA-binding and non-RNA-binding proteins, an SVM system was trained to recognize RNA-binding proteins. A total …

Spatial Queries In The Presence Of Obstacles, Jun Zhang, Dimitris Papadias, Kyriakos Mouratidis, Manli Zhu Mar 2004

Spatial Queries In The Presence Of Obstacles, Jun Zhang, Dimitris Papadias, Kyriakos Mouratidis, Manli Zhu

Research Collection School Of Computing and Information Systems

Despite the existence of obstacles in many database applications, traditional spatial query processing utilizes the Euclidean distance metric assuming that points in space are directly reachable. In this paper, we study spatial queries in the presence of obstacles, where the obstructed distance between two points is defined as the length of the shortest path that connects them without crossing any obstacles. We propose efficient algorithms for the most important query types, namely, range search, nearest neighbors, e-distance joins and closest pairs, considering that both data objects and obstacles are indexed by R-trees. The effectiveness of the proposed solutions is verified …

An Automated Algorithm For Extracting Website Skeleton, Zehua Liu, Wee-Keong Ng, Ee Peng Lim Mar 2004

An Automated Algorithm For Extracting Website Skeleton, Zehua Liu, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The huge amount of information available on the Web has attracted many research efforts into developing wrappers that extract data from webpages. However, as most of the systems for generating wrappers focus on extracting data at page-level, data extraction at site-level remains a manual or semi-automatic process. In this paper, we study the problem of extracting website skeleton, i.e. extracting the underlying hyperlink structure that is used to organize the content pages in a given website. We propose an automated algorithm, called the Sew algorithm, to discover the skeleton of a website. Given a page, the algorithm examines hyperlinks in …

Security Analysis Of Some Proxy Signature, Guilin Wang, Feng Bao, Jianying Zhou, Robert H. Deng Mar 2004

Security Analysis Of Some Proxy Signature, Guilin Wang, Feng Bao, Jianying Zhou, Robert H. Deng

Research Collection School Of Computing and Information Systems

A proxy signature scheme allows an entity to delegate his/her signing capability to another entity in such a way that the latter can sign messages on behalf of the former. Such schemes have been suggested for use in a number of applications, particularly in distributed computing where delegation of rights is quite common. Followed by the first schemes introduced by Mambo, Usuda and Okamoto in 1996, a number of new schemes and improvements have been proposed. In this paper, we present a security analysis of four such schemes newly proposed. By successfully identifying several interesting forgery attacks, we show that …

Authenticating Query Results In Edge Computing, Hwee Hwa Pang, Kian-Lee Tan Mar 2004

Authenticating Query Results In Edge Computing, Hwee Hwa Pang, Kian-Lee Tan

Research Collection School Of Computing and Information Systems

Edge computing pushes application logic and the underlying data to the edge of the network, with the aim of improving availability and scalability. As the edge servers are not necessarily secure, there must be provisions for validating their outputs. This paper proposes a mechanism that creates a verification object (VO) for checking the integrity of each query result produced by an edge server - that values in the result tuples are not tampered with, and that no spurious tuples are introduced. The primary advantages of our proposed mechanism are that the VO is independent of the database size, and that …

Proprietary Relief Without Rescission, Hang Wu Tang Mar 2004

Proprietary Relief Without Rescission, Hang Wu Tang

Research Collection Yong Pung How School Of Law

The decision of the Court of Appeal in Halley v. The Law Society [2003] EWCA Civ 97 has the potential to muddy the waters of the law of rescission. It is a fundamental principle that a fraudulent misrepresentation renders a contract voidable at the instance of the representee (Bristol and West Building Society v. Mothew [1998] Ch. 1, 22). Modern authorities suggest that the representee does not have any proprietary interest in property transferred by him pursuant to the contract before rescission (see Bristol and West Building Society v. Mothew [1998] Ch. 1, 22-23; Twinsectra Ltd. v. Yardley [1999] Lloyd's …

An Empirical Investigation Of Interviewer-Related Factors That Discourage The Use Of High Structure Interviews, Filip Lievens, Anneleen De Paepe Feb 2004

An Empirical Investigation Of Interviewer-Related Factors That Discourage The Use Of High Structure Interviews, Filip Lievens, Anneleen De Paepe

Research Collection Lee Kong Chian School Of Business

High structure interviews appear to be less frequently used in personnel management practice than might be expected given their good reliability and validity. Although several authors have speculated on the factors of resistance to high structure interviews, empirical research is very scarce. Two studies are conducted among experienced human resources representatives who frequently conduct employment interviews. The first study provides a fine-grained description of the degree of structure used in interviews, showing that in most interviews constraints are placed only on the topical areas to be covered and that scoring is done only on multiple criteria. The second study tests …

Management Fashion As Image-Spectacle: The Production Of Best-Selling Management Books, Timothy Adrian Robert Clark, David Greatbatch Feb 2004

Management Fashion As Image-Spectacle: The Production Of Best-Selling Management Books, Timothy Adrian Robert Clark, David Greatbatch

Research Collection Lee Kong Chian School Of Business

Drawing on the work of Guy Debord's Society of the Spectacle and Daniel Boorstin's The Image, this article argues that aesthetic and management fashions are not separate forms, as both represent the preeminence of the image spectacle. Central to this is the increasing emergence of pseudoevents and synthetic products. Using empirical findings from a study of the production of six best-selling management books, it shows that they are manufactured coproductions that result from an intricate editorial process in which the original ideas are moulded in order for them to have a positive impact on the intended audience. Central to this …

Stochastic Analysis And Performance Evaluation Of Wireless Schedulers, R. Rom, Hwee-Pink Tan Feb 2004

Stochastic Analysis And Performance Evaluation Of Wireless Schedulers, R. Rom, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

In the last few years, wireless scheduling algorithms have been proposed by supplementing wireline scheduling algorithms with a wireless adaptation scheme. However, Quality of Service (QoS) bounds have either been derived for flows that perceive error-free conditions or a static worst-case channel condition. Such an assumption of the channel condition is unrealistic, since channel errors are known to be bursty in nature. Hence, these bounds are inadequate to characterize the scheduler's QoS performance. Our research focuses on performing an extensive analysis of wireless scheduling in order to derive statistical QoS performance bounds under realistic channel conditions. In this paper, we …

Thoughts And Propositions, Yoo Guan Tan Feb 2004

Thoughts And Propositions, Yoo Guan Tan

Research Collection School of Social Sciences

In "Reference and Contingency", Gareth Evans maintains that it is possible for an expression both to be a proper name and to have a descriptive sense. Evans calls such names descriptive names. He further claims that if ‘a’ is a name whose reference is fixed by a definite description ‘the φ‘, then ‘a’ will have the same sense as ‘the φ‘. Against Kripke’s objection that names and descriptions are not interchangeable salva veritate within modal contexts, Evans argues that the objection is based upon a false assumption about the connection between contents (thoughts in Frege’s sense) and propositions (sets of …

Cultural Geography: By Whom, For Whom?, Lily Kong Feb 2004

Cultural Geography: By Whom, For Whom?, Lily Kong

Research Collection School of Social Sciences

The "cultural turn," coupled by the "spatial turn" in recent years has drawn significant attention to cultural geography from those in other subdisciplines and disciplines. One might forgive those who sometimes mistake particular research as cultural geography which is in fact conducted by non-geographers or geographers who would not ordinarily identify themselves as cultural geographers. A pointed moment that illustrated this to me was when a sociology colleague insisted that he had read cultural geography, and when asked, indicated that he had read Nigel Thrift and Ash Amin. One interpretation of this is, as Shurmer-Smith (1996) offered through her title …

Local Coordination And Market Equilibria, Shurojit Chatterji, Sayantan Ghosal Feb 2004

Local Coordination And Market Equilibria, Shurojit Chatterji, Sayantan Ghosal

Research Collection School Of Economics

We reformulate the local stability analysis of market equilibria in a competitive market as a local coordination problem in a market game, where the map associating market prices to best-responses of all traders is common knowledge and well-defined both in and out of equilibrium. Initial expectations over market variables differ from their equilibrium values and are not common knowledge. This results in a coordination problem as traders use the structure of the market game to converge back to equilibrium. We analyse a simultaneous move and a sequential move version of the market game and explore the link with local rationalizability.

Closed-Loop Supply Chain Models With Product Remanufacturing, R. Canan Savaskan, Shantanu Bhattacharya, Luk N. Van Wassenhove Feb 2004

Closed-Loop Supply Chain Models With Product Remanufacturing, R. Canan Savaskan, Shantanu Bhattacharya, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

The importance of remanufacturing used products into new ones has been widely recognized in the literature and in practice. In this paper, we address the problem of choosing the appropriate reverse channel structure for the collection of used products from customers. Specifically, we consider a manufacturer who has three options for collecting such products: (1) she can collect them herself directly from the customers, (2) she can provide suitable incentives to an existing retailer (who already has a distribution channel) to induce the collection, or (3) she can subcontract the collection activity to a third party. Based on our observations …

Inventory Model With Seasonal Demand: A Specific Application To Haute Couture, Byung Joon Park, Yih-Long Chang, Johnny C. Ho Feb 2004

Inventory Model With Seasonal Demand: A Specific Application To Haute Couture, Byung Joon Park, Yih-Long Chang, Johnny C. Ho

Research Collection Lee Kong Chian School Of Business

In the stochastic multiperiod inventory problem, a vast majority of the literature deals with demand volume uncertainty. Other dimensions of uncertainty have generally been overlooked. In this paper, we develop a newsboy formulation for the aggregate multiperiod inventory problem intended for products of short sales season and without replenishments. A distinguishing characteristic of our formulation is that it takes a time dimension of demand uncertainty into account. The proposed model is particularly suitable for applications in haute couture, i.e., high fashion industry. The model determines the time of switching primary sales effort from one season to the next as well …

The Chameleon Mediator, Nadja Alexander Feb 2004

The Chameleon Mediator, Nadja Alexander

Research Collection Yong Pung How School Of Law

In the early phases of the Anglo-American mediation movement, certain models were promoted in theory and training and applied in practice. The models differed, depending on the background of the trainers/mediators, the cultural context and the jurisdiction in which the training and practice took place. In the mediation world of shared understandings and collaboration, there was often competition and sometimes even conflict among advocates of the various theories, models, approaches and styles.

Removing The Shadow Of Suspicion: The Effects Of Apology Versus Denial For Repairing Competence- Versus Integrity-Based Trust Violations, Peter H. Kim, Donald L. Ferrin, Cecily D. Cooper, Kurt T. Dirks Feb 2004

Removing The Shadow Of Suspicion: The Effects Of Apology Versus Denial For Repairing Competence- Versus Integrity-Based Trust Violations, Peter H. Kim, Donald L. Ferrin, Cecily D. Cooper, Kurt T. Dirks

Research Collection Lee Kong Chian School Of Business

Two studies were conducted to examine the implications of an apology versus a denial for repairing trust after an alleged violation. Results reveal that trust was repaired more successfully when mistrusted parties (a) apologized for violations concerning matters of competence but denied culpability for violations concerning matters of integrity, and (b) had apologized for violations when there was subsequent evidence of guilt but had denied culpability for violations when there was subsequent evidence of innocence. Supplementary analyses also revealed that the interactive effects of violation type and violation response on participants' trusting intentions were mediated by their trusting beliefs. Combined, …

Tool Support For Two-Tiered Architectural Design For Automotive Control Systems, Kevin Steppe, Greg Bylenok, David Garlan, Bradley Schmerl, Kanat Abirov, Nataliya Shevchenko Jan 2004

Tool Support For Two-Tiered Architectural Design For Automotive Control Systems, Kevin Steppe, Greg Bylenok, David Garlan, Bradley Schmerl, Kanat Abirov, Nataliya Shevchenko

Research Collection School Of Computing and Information Systems

An attractive approach to architecture-based design is to structure the development process into two tiers. The top tier represents the abstract design (or architecture) of a system in terms of abstract components. The bottom tier refines that design by making specific implementation decisions, such as platform, middleware, and component implementations. While attractive in principle, there has been relatively little industrial-based experience to shed light on problems and solutions involved in such an approach. In this paper we describe our experience in developing tools to introduce a two-tiered model-based approach to the design of Ford Motor Company’s automotive control systems, highlighting …

Operational Hedging: A Review With Discussion, Onur Boyabatli, L. Beril Toktay Jan 2004

Operational Hedging: A Review With Discussion, Onur Boyabatli, L. Beril Toktay

Research Collection Lee Kong Chian School Of Business

Motivated by the increasing prevalence of operational hedging in corporate-level risk management programs, this paper provides an extensive overview and synthesis of the existing literature on operational hedging. In particular, we focus on the treatment of operational hedging in the operations management literature. We then explore how the concept of operational hedging is studied in the fields of finance, strategy and international business. Finally, we discuss and critique the approaches adopted in the operations management literature in the context of the broader literature on the topic.

Heuristics For A Brokering Set Packing Problem, Yunso Guo, Andrew Lim, Brian Rodrigues, Yi Zhu

Research Collection Lee Kong Chian School Of Business

In this paper we formulate the combinatorial auction brokering problem as a Set Packing Problem (SPP) and apply a simulated annealing heuristic to solve SPP. Experimental results are compared with a recent heuristic algorithm and also with the CPLEX Integer Programming solver where we found that the simulated annealing approach outperforms the previous heuristic method and CPLEX obtaining results within smaller timescales.

Embedded Co-Operation In The Context Of Singapore's Regionalization Program: The Batamindo Experiment Revisited, Caroline Yeoh, Adeline Kwan, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

The development of Singapore-styled industrial parks has resided on the country’s ability to negotiate investment concessions at inter-government level, to provide superior infrastructure, and where existing, through the links to influential business groups in the investment location. Singapore’s first transborder industrialization project in Batam (Indonesia) reflects this stratagem. This paper revisits the debate on the attractiveness of the low-cost investment enclaves for multinational investments, with insights from Batamindo Industrial Park. Through evidence from on-site interviews and case studies, this paper concludes that while the project’s progress to date has been largely overshadowed by socio-political uncertainties in the host environment, its …

What Are The "Four Roots Of Capacity And Nature"?, Alan Kam Leung Chan Jan 2004

What Are The "Four Roots Of Capacity And Nature"?, Alan Kam Leung Chan

Research Collection College of Integrative Studies

During the third century C.E., a debate on the relationship between “capacity” (cai 才) and “nature” (xing 性) captured the imagination of the Chinese elite. Historical sources relate that four views were put forward on the subject, which continued to dominate the intellectual scene during the fourth and fifth centuries. Yin Hao 殷 浩 (306–356), a major statesman and leader of the literati, for example, was known especially for his expertise on the four views of “capacity and nature” (caixing) (Shishuo xinyu 1992, 4.34; cf. Mather 1976, 110).1 Writing in the fifth century, Wang Sengqian 王 僧 虔 (426–485) observed …

The Structuralist Perspective On Real Exchange Rate, Share Price Level And Employment Path: What Room Is Left For Money?, Edmund S. Phelps, Hian Teck Hoon, Gylfi Zoega

Research Collection School Of Economics

The current sluggish performance of the US economy follows one of the more remarkable booms in modern history. The late 1990s was a period of simultaneous output and productivity growth,1 low unemployment and stable inflation, culminating in an unemployment rate of only 3.9% in the fourth quarter of the year 2000. The absence of rising inflation during this period came as a surprise to many since the level of the natural rate of unemployment was commonly estimated to be in the range of 5-6% by the mid 1990s. The non-inflationary boom, however, reminds one of another episode where non-monetary forces …
