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 …

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 …

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, …

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 …

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.

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 …

Evaluating The Usability Of A Group Support System Using Co-Discovery, Keng Siau Jan 2004

Evaluating The Usability Of A Group Support System Using Co-Discovery, Keng Siau

Research Collection School Of Computing and Information Systems

Group Support Systems (GSSs) have emerged as a new type of information system to aid group decision-making. With the proliferation of such systems in organizations, evaluation of GSSs is becoming increasingly important. This paper reports the evaluation of an existing GSS. Our usability framework consists of nine dimensions: visual clarity, consistency, compatibility, informative feedback, explicitness, flexibility and control, error prevention and correction, ease of learning, and ease of use. We make use of the co-discovery method where teams of two participants perform tasks together while being observed. The study involves questionnaires and interview sessions. The strengths and weaknesses of the …

From Cannibalism To Empowerment: An Analects-Inspired Attempt To Balance Community And Liberty, Sor-Hoon Tan Jan 2004

From Cannibalism To Empowerment: An Analects-Inspired Attempt To Balance Community And Liberty, Sor-Hoon Tan

Research Collection School of Social Sciences

The Confucian tradition has often been credited with a strong allegiance to the value of community. It recognizes that certain goods might be attained through special forms of human association, but not by any solitary individual. Are such community goods attained at the expense of the liberty of individual members? Philosophers have struggled with the tension between liberty and community since the dawn of Western philosophy. Aristotle complained about the false idea of liberty as "doing what one likes," which is contradictory to the true interests of the polis.2 Such lib- erty, or rather license, is undoubtedly detrimental to any …

Challenges To Academic Marketing: Toward The Next Decade, David B. Montgomery Jan 2004

Challenges To Academic Marketing: Toward The Next Decade, David B. Montgomery

Research Collection Lee Kong Chian School Of Business

At the turn of the century and millennium, the Marketing Science Institute and the American Marketing Association undertook in a conference and a special issue of the Journal of Marketing to examine what were seen as fundamental issues and directions for marketing in the dawning millennium. A series of competitively commissioned papers addressed such questions as: How do customers and consumers really behave? How do markets function and evolve? How do firms relate to their markets? And what are the contributions of marketing to organizational performance and societal welfare? These questions were thought to best satisfy the criteria of differentiation, …

Metaheuristics With Local Search Techniques For Retail Shelf-Space Optimization, Andrew Lim, Brian Rodrigues, Xingwen Zhang Jan 2004

Metaheuristics With Local Search Techniques For Retail Shelf-Space Optimization, Andrew Lim, Brian Rodrigues, Xingwen Zhang

Research Collection Lee Kong Chian School Of Business

Efficient shelf-space allocation can provide retailers with a competitive edge. While there has been little study on this subject, there is great interest in improving product allocation in the retail industry. This paper examines a practicable linear allocation model for optimizing shelf-space allocation. It extends the model to address other requirements such as product groupings and nonlinear profit functions. Besides providing a network flow solution, we put forward a strategy that combines a strong local search with a metaheuristic approach to space allocation. This strategy is flexible and efficient, as it can address both linear and nonlinear problems of realistic …

Resource-Based Theory And Its Link To The Global Strategy, Structure And Performance Relationship: An Integrative Framework, Olivier Furrer, Jeffrey A. Krug, D. Sudharshan, Howard Thomas Jan 2004

Resource-Based Theory And Its Link To The Global Strategy, Structure And Performance Relationship: An Integrative Framework, Olivier Furrer, Jeffrey A. Krug, D. Sudharshan, Howard Thomas

Research Collection Lee Kong Chian School Of Business

The global strategy literature provides a basis for examining strategy, structure, and performance relationships in multinational firms. We develop a framework that examines these relationships and their linkages to the firm's intangible asset portfolio. Drawing on resource-based theory, this framework suggests that an on-going multinational firm's worldwide performance is dependent on the fit between its intangible asset portfolio, foreign market entry strategies, partner relationships, and worldwide organisational structure. Each of these dimensions can be linked back to the firm's worldwide strategy and the characteristics of its industry. Implications for research are discussed.

Privatizing Telecoms And Residual State Influence On Financial Performance, Burkhard N. Schrage, Paul M. Vaaler Jan 2004

Privatizing Telecoms And Residual State Influence On Financial Performance, Burkhard N. Schrage, Paul M. Vaaler

Research Collection Lee Kong Chian School Of Business

We test competing theoretical perspectives explaining likely shareholder returns from material investment decisions announced by privatizing telecommunications firms (telecoms) with varying levels of residual state ownership. A principal-agent perspective suggests that decrease in residual state ownership in privatizing telecoms leads to more positive shareholder returns. Over time, this effect increases. An alternative credible privatization perspective suggests that retention of substantial (though not controlling) residual state ownership leads to more positive shareholder returns, but only in the short run. Over time this ownership effect fades quickly. We examine empirical support for these competing perspectives with an event study analyzing cumulative abnormal …

Bias In The Correlated Uniqueness Model For Mtmm Data, James M. Conway, Filip Lievens, Steven E. Scullen, Charles E. Lance Jan 2004

Bias In The Correlated Uniqueness Model For Mtmm Data, James M. Conway, Filip Lievens, Steven E. Scullen, Charles E. Lance

Research Collection Lee Kong Chian School Of Business

This simulation investigates bias in trait factor loadings and intercorrelations when analyzing multitrait-multimethod (MTMM) data using the correlated uniqueness (CU) confirmatory factor analysis (CFA) model. A theoretical weakness of the CU model is the assumption of uncorrelated methods. However, previous simulation studies have shown little bias in trait estimates even when true method correlations are large. We hypothesized that there would be substantial bias when both method factor correlations and method factor loadings were large. We generated simulated sample data using population parameters based on our review of actual MTMM results. Results confirmed the prediction; substantial bias occurred in trait …

Book-Length Scholarly Essays As A Hybrid Genre In Science, Susheela Abraham Varghese, Sunita Anne Abraham Jan 2004

Book-Length Scholarly Essays As A Hybrid Genre In Science, Susheela Abraham Varghese, Sunita Anne Abraham

Research Collection Lee Kong Chian School Of Business

Drawing on existing work on popularizations, this investigation of book-length scholarly essays by practicing scientists across three disciplines reveals a hybrid genre that is neither popularization nor research report. The study utilizes both textual analysis and personal commentary from the writer-researchers to achieve a three-way comparison between the popularization, research article, and the book-length scholarly essay that clarifies how these essays contribute to the authors’ academic agendas. Writing for both a general audience and a jury of their peers, these academics employ an argumentative generic structure. Such argumentation develops a rhetoric of rational inquiry, where understanding how answers to perplexing …

Emotional Intelligence And Negotiation: The Tension Between Creating And Claiming Value, Maw Der Foo, Hillary Anger Elfenbein, Hwee Hoon Tan, Voon Chuan Aik Jan 2004

Emotional Intelligence And Negotiation: The Tension Between Creating And Claiming Value, Maw Der Foo, Hillary Anger Elfenbein, Hwee Hoon Tan, Voon Chuan Aik

Research Collection Lee Kong Chian School Of Business

As a departure from past research on emotional intelligence (EI), which generally examines the influence of an individual's level of EI on that individual's consequences, we examined relationships between the emotional intelligence (EI) of both members of dyads involved in a negotiation in order to explain objective and subjective outcomes. As expected, individuals high in EI reported a more positive experience. However, surprisingly, such individuals also achieved significantly lower objective scores than their counterparts. By contrast, having a partner high in El predicted greater objective gain, and a more positive negotiating experience. Thus, high EI individuals appeared to benefit in …

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 …

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 …

China’S Pragmatist Experiment: Hu Shih’S Pragmatism And Dewey’S Influence In China, Sor-Hoon Tan Jan 2004

China’S Pragmatist Experiment: Hu Shih’S Pragmatism And Dewey’S Influence In China, Sor-Hoon Tan

Research Collection School of Social Sciences

In the 1920s, John Dewey’s followers in China, led by his student HuShih, attempted to put his pragmatism into practice in their quest for democracy.This essay compares Hu Shih’s thought, especially his emphasis on pragmatism asmethod, with Dewey’s philosophical positions and evaluates Hu’s achievement asa pragmatist in the context of the tumultuous times he lived in. It assesses Hu’sclaim that the means to democracy lies in education rather than politics, sincedemocracy as a way of life requires a cultural renewal beyond institutionalchanges. It argues that a problem-centered approach to social change does notpreclude radical action, even revolution. But pragmatism is …

Moore's Paradox And Self-Knowledge, John N. Williams

Research Collection School of Social Sciences

What explanation is there of the source of my justification for my beliefs about my beliefs that respects the fact that I am normally the best authority on them? Moore's paradox demands an explanation of the absurdity of believing or asserting possible truths of the forms p but I don't believe that p or p but I believe that not-p. I argue for Evans principle that whatever justifies me in believing that p also justifies me in believing that I believe that p. This helps explain how I come to know my own beliefs and also shows that it is …

Does The Parliament Make A Difference? The Role Of The Italian Parliament In Financial Policy, Carolyn Forestiere, Riccardo Pelizzo Jan 2004

Does The Parliament Make A Difference? The Role Of The Italian Parliament In Financial Policy, Carolyn Forestiere, Riccardo Pelizzo

Research Collection School of Social Sciences

A recent survey conducted in a sample of 83 countries by the Inter-Parliamentary Union in collaboration with the World Bank Institute on the Relations between the Legislature and the Executive in the Context of Parliamentary Oversight allows cross-national comparison for the role of legislatures in the budgetary process. One of the survey’s most significant indications is that legislatures in presidential systems are generally more involved in the preparation of the budget than legislatures in either parliamentary or semi-presidential systems. The picture, however, is very different when we look at legislatures’ oversight of the budget. Parliaments are generally more involved in …

Tools For Legislative Oversight: An Empirical Investigation, Riccardo Pelizzo, Rick Stapenhurst Jan 2004

Tools For Legislative Oversight: An Empirical Investigation, Riccardo Pelizzo, Rick Stapenhurst

Research Collection School of Social Sciences

Parliaments are the institutions through which governments are held accountable to the electorate. They have a wide range of tools with which to carry out this oversight function, but until recently little analysis had been undertaken on the characteristics or use of such tools. This paper uses data for 83 countries that was collected in 2001 to investigate whether the oversight potential relates to three variables, namely the form of government (presidential, semi-presidential, or parliamentary), per capita income levels, and the level of democracy. The paper finds that oversight potential is greatly affected by the form of government, per capita …

The Great Divide: Considering Section 157a Of The Singapore Companies Act, Pearlie Koh Jan 2004

The Great Divide: Considering Section 157a Of The Singapore Companies Act, Pearlie Koh

Research Collection Yong Pung How School Of Law

The manner in which the powers of a company are carved out to be exercised by either the general meeting of shareholders or its board of directors is often a matter of interpretation of the constitution of the company. This approach retains a fair amount of flexibility in the differing models of power allocation that may be adopted by incorporators, but once carved out, the power allocation usually remains sacrosanct until such time as the constitution is validly altered. This was the position in Singapore before 2003. In 2003, the Companies Act of Singapore was amended to include s 157A, …

Prisons As Progressive Punishment? The State Of Corrective Services, Mark Findlay

Research Collection Yong Pung How School Of Law

In the early days of his third term as Premier of New South Wales, Bob Carr challenged his government to move away from current law and order politics and to come up with a more progressive approach to punishment. Central to this would be a reconsideration of the place of the prison in criminal justice. Prisons, by their nature and the communities they house, suffer more acutely from the factors of social exclusion that characterise the underprivileged sectors of Australian society. Without the exacerbation of a custodial experience, these characteristics alone militate against the successful reintegration of prisoners back into …

The Politics Of Wto Enforcement Mechanism, Pao-Li Chang Jan 2004

The Politics Of Wto Enforcement Mechanism, Pao-Li Chang

Research Collection School Of Economics

This paper attempts to develop a formal economic framework to analyze the influences of domestic political considerations by democratic governments in shaping the WTO enforcement outcomes in the wake of a violation ruling against the defendant. Since a different mix of import and export sectors in the defendant and complainant country will benefit from the various potential enforcement outcomes, they become competing forces which steer the strategic interactions between the disputing governments. The results of the paper illustrate the complainant’s strategy in selecting the retaliation list, and the likelihood of the defendant’s compliance or compensation in response to the proposed …
