Design Of Antiresonant-Reflecting Optical Waveguide-Type Vertical-Coupled Surface-Emitting Lasers Using Transfer Matrix Method, Chyng Wen Tee, C. C. Tan, S. F. Yu Sep 2003

Design Of Antiresonant-Reflecting Optical Waveguide-Type Vertical-Coupled Surface-Emitting Lasers Using Transfer Matrix Method, Chyng Wen Tee, C. C. Tan, S. F. Yu

Research Collection Lee Kong Chian School Of Business

A simple transfer matrix method is proposed to calculate the radiation losses of a cylindrical antiresonant-reflecting optical waveguide (ARROW). It is found that the planar approximation underestimates the radiation losses but overestimates the design tolerance of the ARROW-type vertical-cavity surface-emitting lasers (VCSELs). An iteration technique, which is incorporated with the transfer matrix method, is also developed to design ARROW-type VCSELs for minimum radiation losses in a more effective manner.

In Praise Of The Strange Virtue Of People-Smuggling, Chandran Kukathas Sep 2003

In Praise Of The Strange Virtue Of People-Smuggling, Chandran Kukathas

Research Collection School of Social Sciences

Almost everyone is against people-smuggling. The refugee advocate excoriating the government for its mistreatment of asylum seekers, no less than the departmental official bemoaning the numbers of boat people landing on Australian shores, feels well-justified in insisting that, somehow, something must be done to put an end to this 'evil trade'. On the scale of virtue, the people smuggler appears barely a notch above (and for many, several notches below) the drug dealer, the child molester, or the gangster.

Interorganizational Systems And Competitive Advantages – Lessons From History, Keng Siau Sep 2003

Interorganizational Systems And Competitive Advantages – Lessons From History, Keng Siau

Research Collection School Of Computing and Information Systems

Global business constantly faces radical transformations stemming from advances in information technology (IT). The concept of gaining competitive advantages by linking information systems across organizations (e.g., supply chain integration) has taken on an overtone of dogma in many business circles. Such electronic linkages are known as Interorganizational Systems (IOS). Lately, the growing importance and easy accessibility of the Internet have propelled IOS to a new height. Undoubtedly, IOS can have a great impact on organizational performance and industry structure. However, IT such as the Internet is readily available to all companies, and most IOS concepts can be easily replicated. Followers …

Re-Engaging Chineseness: Political, Economic And Cultural Imperatives Of Nation-Building In Singapore, Eugene K. B. Tan Sep 2003

Re-Engaging Chineseness: Political, Economic And Cultural Imperatives Of Nation-Building In Singapore, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

This article examines the management of Chinese identity and culture since Singapore attained independence in 1965. Due to the delicate regional environment, ethnic Chinese identity has been closely managed by the ruling elites, which have been dominated by the English-educated Chinese. There is the evolution from a deliberate policy of maintaining a low-key ethnic Chinese profile to the recent effort to re-sinicize--in form--the majority ethnic group. The article examines the policy impulses and implications for such a landmark change in reconceptualizing the Chinese-Singapore identity, which can be attributed to the needs of regime maintenance buttressed by Confucian ethos as well …

E-Ducation, J. Erickson, Keng Siau

Research Collection School Of Computing and Information Systems

Most educators are convinced Internet technology will sharply alter the educational landscape of the future, but considerable uncertainly still exists as to exactly how the classroom will evolve over the next decade. Many of the relevant technologies in development are a direct result of the Internet2 Project [1], a collaboration of more than 200 universities working closely with private industry and the National Science Foundation to build and promote an advanced network using state-of-the-art technology and applications. But how the classroom evolves depends not only on advanced Internet2 technologies, which are discussed later in the article, but also on issues …

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu Sep 2003

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu

Research Collection Lee Kong Chian School Of Business

We show that organization structure of a stock exchange matters by utilizing the unique setting prevailing in India. India has two major stock markets, the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). These two exchanges adopt similar trading systems, trade essentially identical stocks, and follow the same trading hours. However, these exchanges have different organizational structures: BSE is mutualized whereas NSE is demutualized. Using the Hasbrouck [Review of Financial Studies 6 (1993) 191] measure of market quality we show that NSE provides a better quality market than BSE. This result is consistent with the work of Domowitz …

For A Few Euros More: Campaign Spending Effects In The Irish Local Elections Of 1999, Kenneth Benoit, Michael Marsh Sep 2003

For A Few Euros More: Campaign Spending Effects In The Irish Local Elections Of 1999, Kenneth Benoit, Michael Marsh

Research Collection School of Social Sciences

Although perceived by candidates and parties as important in affecting political outcomes, the link between spending and success in multi-candidate, multiparty election campaigns remains unproven. Not only are there relatively few studies of campaign spending effects in multi-party systems, there are none examining the effect under the Single Transferable Vote (STV) electoral system. Our study examines spending effects in the Irish local elections of 1999 using STV with district magnitudes between 3 and 7 seats, contested by a median of 10 candidates in each district. Using detailed data on 1,838 candidates from 180 local constituencies and 30 councils, we provide …

An Issue Of Absolution: Section 391 Of The Companies Act, Pearlie Koh Sep 2003

An Issue Of Absolution: Section 391 Of The Companies Act, Pearlie Koh

Research Collection Yong Pung How School Of Law

There is an obvious tension in the imposition of directors’ duties. Whilst directors being the management, and therefore the eyes, ears and brain of the corporate person, must be given sufficient discretion to take on entrepreneurial (and hence risky) ventures with a view to profit maximisation, there is also the need to curb excesses, as the potential or opportunity for mismanagement, negligence and fraud is omnipresent. [T]his short article considers section 391 of the Companies Act (Cap 50), arguably the statutory nemesis of directors’ duties. Section 391 gives jurisdiction to the court hearing the case to relieve an officer from …

What To Do On Spring Break? The Role Of Predicted, On-Line, And Remembered Experience In Future Choice, Derrick Wirtz, Justin Kruger, Christie N. Scollon, Ed Diener Sep 2003

What To Do On Spring Break? The Role Of Predicted, On-Line, And Remembered Experience In Future Choice, Derrick Wirtz, Justin Kruger, Christie N. Scollon, Ed Diener

Research Collection School of Social Sciences

When individuals choose future activities on the basis of their past experiences, what guides those choices? The present study compared students' predicted, on-line, and remembered spring-break experiences, as well as the influence of these factors on students' desire to take a similar vacation in the future. Predicted and remembered experiences were both more positive—and, paradoxically, more negative—than on-line experiences. Of key importance, path analyses revealed that remembered experience, but neither on-line nor anticipated experience, directly predicted the desire to repeat the experience. These results suggest that although on-line measures may be superior to retrospective measures for approximating objective experience, retrospective …

The Effects Of Sexual Orientation On Hirability Ratings: An Experimental Study, Greet Van Hoye, Filip Lievens Sep 2003

The Effects Of Sexual Orientation On Hirability Ratings: An Experimental Study, Greet Van Hoye, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Despite its rising importance, empirical research about sexual orientation in the workplace is still scarce. This experimental study examined if gay candidates, with the same work-related qualities as heterosexual candidates, would be judged less favorably in a personnel selection context. Written candidate profiles were varied in a 3 x 3 between-subjects factorial design, with candidate quality and sexual orientation as experimental variables. Our results indicated that the hirability ratings of 135 selection professionals were based on candidate quality and that no discrimination on the basis of sexual orientation occurred. Implications of these findings and directions for future research are discussed.

Aggregated Causal Maps: An Approach To Elicit And Aggregate The Knowledge Of Multiple Experts, S. Nadkarni, Fiona Fui-Hoon Nah Sep 2003

Aggregated Causal Maps: An Approach To Elicit And Aggregate The Knowledge Of Multiple Experts, S. Nadkarni, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

This paper presents a systematic procedure to elicit and aggregate the knowledge of multiple individual experts and represent it in the form of an Aggregated Causal Map (ACM). This procedure differs from existing methods in two ways. First, unlike other methods, this method does not rely on group interaction in eliciting knowledge of multiple experts, and, therefore, is not fraught with biases associated with group dynamics. Second, this method uses both the idiographic and nomothetic approaches while existing methods focus on nomothetic approaches to knowledge elicitation. We draw on the strengths of both approaches by using the idiographic approach to …

The Role Of United Charities In Fundraising: The Case Of Singapore, Vincent Chua, Chung Ming Wong Sep 2003

The Role Of United Charities In Fundraising: The Case Of Singapore, Vincent Chua, Chung Ming Wong

Research Collection School Of Economics

Theory suggests that a united charity helps to economize on fundraising costs by reducing competition for donations among member charities. However, donors often cannot control the allocation of their donations, and charities may dislike the monitoring of their activities. This paper examines these and other issues relating to the Community Chest of Singapore. The results, based on analysis of financial positions and fundraising costs of a large number of charities, suggest that the Community Chest does possess important fundraising advantages. Thus charities in financial difficulties or in need of funds for additional programs tend to seek membership. However, organizations that …

Antecedents Of Consumer Trust In B-To-C Electronic Commerce, Dan J. Kim, Donald L. Ferrin, H. Raghav Rao Aug 2003

Antecedents Of Consumer Trust In B-To-C Electronic Commerce, Dan J. Kim, Donald L. Ferrin, H. Raghav Rao

Research Collection Lee Kong Chian School Of Business

Despite the importance of trust in electronic commerce, there is insufficient theory and evidence concerning the determinants of consumer trust about an Internet vendor’s trustworthiness, and the influence of consumer trust on the consumer’s purchasing intention. The purpose of this study is to: i) develop a theoretical framework identifying the antecedents of a consumer’s trust and purchase intention, ii) test the proposed model using Structural Equation Modeling, analyzing Internet consumer behavior data collected via a Web survey, and iii) provide theoretical and managerial implications. The results of the study show that consumers’ disposition to trust, privacy protection, security protection, consumers’ …

Operationalizing Technology Improvements In Product Development Decision-Making, Shantanu Bhattacharya, V. Krishnan, Vijay Mahajan Aug 2003

Operationalizing Technology Improvements In Product Development Decision-Making, Shantanu Bhattacharya, V. Krishnan, Vijay Mahajan

Research Collection Lee Kong Chian School Of Business

Achieving competitive advantage and price premiums in many technology-based markets requires the incorporation of current technology in new products. To do so, firms in hyper-competitive environments increasingly plan and design their products concurrent with the independent development and validation of underlying technologies. Simultaneous validation of a core technology has important implications for a company's product positioning and launch sequence decisions making these traditional marketing decisions relevant to operations managers. Prior research has shown that to minimize cannibalization in the absence of such improvements in technology, a firm should not launch low-end products before high-end products. However, concurrent evolution of technology …

A Study On Tolerable Waiting Time: How Long Are Web Users Willing To Wait?, Fiona Fui-Hoon Nah Aug 2003

A Study On Tolerable Waiting Time: How Long Are Web Users Willing To Wait?, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

The WWW has become an important channel for information access, electronic commerce, and publication. With an exponential increase in the number of Web users and the popularity of multimedia technology, users often face a long waiting time for downloading Web pages. Although various technologies and techniques have been implemented to alleviate the situation and to comfort the impatient users, little research has been done to assess what constitutes an acceptable and tolerable waiting time for Web users. This research reviews the literature on computer response time and users’ waiting time, and assesses Web users’ tolerable waiting time in information retrieval. …

Adrenocortical Adenoma And Carcinoma: Histopathological And Molecular Comparative Analysis, A. Stojadinovic, M. F. Brennan, A. Hoos, A. Omeroglu, Denis H. Y. Leung, M. Dudas, A. Nissan, C. Cordon-Cardo, R.A. Ghossein Aug 2003

Adrenocortical Adenoma And Carcinoma: Histopathological And Molecular Comparative Analysis, A. Stojadinovic, M. F. Brennan, A. Hoos, A. Omeroglu, Denis H. Y. Leung, M. Dudas, A. Nissan, C. Cordon-Cardo, R.A. Ghossein

Research Collection School Of Economics

We compared histomorphological features and molecular expression profiles of adrenocortical adenomas (ACAd) and carcinomas (ACCa). A critical histopathological review (mean, 11 slides per patient) was conducted of 37 ACAd and 67 ACCa. Paraffin-embedded tissue cores of ACAd (n = 33) and ACCa (n = 38) were arrayed in triplicate on tissue microarrays. Expression profiles of p53, mdm-2, p21, Bcl-2, cyclin D1, p27, and Ki-67 were investigated by immunohistochemistry and correlated with histopathology and patient outcome using standard statistical methodology. Median follow-up period was 5 years. Tumor necrosis, atypical mitoses, and >1 mitosis per 50 high-power fields were factors that were …

Analysis Of Private Transfers With Panel Fixed Effect Censored Model Estimator, Sung Jin Kang, Myoung-Jae Lee Aug 2003

Analysis Of Private Transfers With Panel Fixed Effect Censored Model Estimator, Sung Jin Kang, Myoung-Jae Lee

Research Collection School Of Economics

Understanding private transfer is important for safety-net policies because private transfer provides economic benefits similar to those of public programs such as unemployment insurance and pension. Applying Honoré’s [Econometrica 60 (1992) 533] panel fixed-effect censored model estimator to Korean data, we show that private transfer is altruistically motivated and there is a strong crowding-out effect of public transfer on private transfer. We also find that low-income people suffered to different degrees during the financial crisis period of 1997 to 1998. This finding and the crowding-out effect may be taken as failures of the Korean public transfer programs during the period.

Open Versus Sealed-Bid Auctions: Testing For Revenue Equivalence Under Singapore's Vehicle Quota System, Winston T. H. Koh, Roberto S. Mariano, Yiu Kuen Tse Aug 2003

Open Versus Sealed-Bid Auctions: Testing For Revenue Equivalence Under Singapore's Vehicle Quota System, Winston T. H. Koh, Roberto S. Mariano, Yiu Kuen Tse

Research Collection School Of Economics

Using data from the auction of vehicle quota licenses in Singapore, we study if revenue equivalence holds when the auction format was switched from a sealed-bid format (May 1990 to June 2001) to an open bidding format since July 2001. Our econometric analysis indicates the change in auction format led to a change in bidding behavior. On average, the quota license premium under the open bidding format is about US$1,000 (about 7.5% of the Category E license price in June 2001) lower, compared to the forecast level that would have prevailed if there had been no change in the auction …

Dictatorial Domains, Navin Aswal, Shurojit Chatterji, Arunava Sen Aug 2003

Dictatorial Domains, Navin Aswal, Shurojit Chatterji, Arunava Sen

Research Collection School Of Economics

In this paper, we introduce the notion of a linked domain and prove that a non-manipulable social choice function defined on such a domain must be dictatorial. This result not only generalizes the Gibbard-Satterthwaite Theorem but also demonstrates that the equivalence between dictatorship and non-manipulability is far more robust than suggested by that theorem. We provide an application of this result in a particular model of voting. We also provide a necessary condition for a domain to be dictatorial and use it to characterize dictatorial domains in the cases where the number of alternatives is three.

Broadcast Scheduling For Mobile Advertising, Bert De Reyck, Zeger Degraeve

Research Collection Lee Kong Chian School Of Business

We describe a broadcast scheduling system developed for a precision marketing firm specialized in location-sensitive permission-based mobile advertising using SMS (Short Message Service) text messaging. Text messages containing advertisements were sent to registered customers when they were shopping in one of two shopping centers in the vicinity of London. The ads typically contained a limited-time promotional offer. The company's problem was deciding which ads to send out to which customers at what particular time, given a limited capacity of broadcast time slots, while maximizing customer response and revenues from retailers paying for each ad broadcast. We solved the problem using …

Information Systems Requirements Determination And Analysis: A Mental Modeling Approach, Keng Siau, X. Tan Aug 2003

Information Systems Requirements Determination And Analysis: A Mental Modeling Approach, Keng Siau, X. Tan

Research Collection School Of Computing and Information Systems

Regardless of the system development methodology adopted, being able to understand users’ informationrequirements is vital to the success of an information systems project. The intrinsic communications obstaclesexist within an individual user, among users, and between users and systems analysts. Different requirementsdetermination and analysis (RDA) techniques have been widely used with different outcomes. Some limitations of these techniques can be identified. In this paper, we propose a mental modeling approach to support RDA. Popular in other disciplines, mental modeling techniques have some distinct advantages to overcome some intrinsic communication obstacles in RDA, and to complement other techniques.

A Generic Object-Oriented Tabu Search Framework, Hoong Chuin Lau, Wee Chong Wan, Xiaomin Jia Aug 2003

A Generic Object-Oriented Tabu Search Framework, Hoong Chuin Lau, Wee Chong Wan, Xiaomin Jia

Research Collection School Of Computing and Information Systems

Presently, most tabu search designers devise their applications without considering the potential of design and code reuse, which consequently prolong the development of subsequent applications. In this paper, we propose a software solution known as Tabu Search Framework (TSF), which is a generic C++ software framework for tabu search implementation. The framework excels in code recycling through the use of a welldesigned set of generic abstract classes that clearly define their collaborative roles in the algorithm. Additionally, the framework incorporates a centralized process and control mechanism that enhances the search with intelligence. This results in a generic framework that is …

Performance Sensitivity And Fairness Of Ecn-Aware 'Modified Tcp', Archan Misra, Teunis Ott Aug 2003

Performance Sensitivity And Fairness Of Ecn-Aware 'Modified Tcp', Archan Misra, Teunis Ott

Research Collection School Of Computing and Information Systems

The paper discusses how Explicit Congestion Notification (ECN) can be used to devise a congestion control mechanism for the Internet, which is more rapidly reactive and allows best-effort flows to rapidly adjust to fluctuations in available capacity. Our ECN-mod protocol involves simple modifications to TCP behavior and leverages more aggressive marking-based router feedback.Simulations show that ECN-mod is better than TCP NewReno even for Web-style intermittent traffic sources, and makes the link utilization significantly less sensitive to the variation in the number of active flows. Simulations also show that, while ECN-mod flows obtain a larger portion of the available capacity than …

What Has Luck Got To Do With Economic Development? An Interpretation Of Resurgent Asia's Growth Experience, Hing-Man Leung, Swee Liang Tan, Zhenlin Yang Jul 2003

What Has Luck Got To Do With Economic Development? An Interpretation Of Resurgent Asia's Growth Experience, Hing-Man Leung, Swee Liang Tan, Zhenlin Yang

Research Collection School Of Economics

This paper critically reexamines the belief, currently gathering strength in the literature, that economic development depends on good luck rather than on good policy, and that Prometheus is “unchained by chance”. While it is impossible to disprove the role of luck in growth, we argue that luck is endogenous, and good luck is a function of good policy. Luck favours those who strive. Again contrary to common belief, we show that resurgent Asian economies have endured more, not less, than their fair share of economic volatility. They learned their lessons by success and failures, and luck is endogenous through learning-by-investing.
