Foreign Country Priorities In The Internationalization Process: A Measure And An Exploratory Test On British Firms, Timothy Adrian Robert Clark, Derek S. Pugh Jun 2001

Foreign Country Priorities In The Internationalization Process: A Measure And An Exploratory Test On British Firms, Timothy Adrian Robert Clark, Derek S. Pugh

Research Collection Lee Kong Chian School Of Business

After a critical analysis of the psychic distance aspect of the Uppsala model of internationalization and empirical studies to test it, this paper proposes a measure to enable comparison between target foreign countries in the priority given them in the internationalization process. An International Priority Index is developed for each target country, and used as the dependent variable in a model to analyze the effects of the independent variables of size of market, affluence of market, geographical distance and cultural distance on foreign country priority choice of home country firms. The measure and the model are given a first test …

An Investigation Of Goodwill Accounting Policy Choice Within A Specific Knowledge Framework, Pearl H. N. Tan Jun 2001

An Investigation Of Goodwill Accounting Policy Choice Within A Specific Knowledge Framework, Pearl H. N. Tan

Research Collection School Of Accountancy

This study, using Singapore data, investigates the relationship between Chief Executive Officers' (CEO) specific knowledge and the accounting method choice on capitalisation of goodwill. International Accounting Standard 22 (1987), applicable in Singapore in 1996, the year of the study, permits a choice between capitalisation with subsequent amortisation and immediate write-off of goodwill to reserves. This study proposes a positive relationship between human capital specificity of CEOs and the recognition of purchased goodwill on the balance sheet. Specific knowledge is unique to firms and is acquired through experience. Given that specialised assets arise from firm-specific circumstances, firm-specific knowledge potentially explains the …

Intelligent Island Discourse: Singapore’S Discursive Negotiation With Technology, Alwyn Lim Jun 2001

Intelligent Island Discourse: Singapore’S Discursive Negotiation With Technology, Alwyn Lim

Research Collection School of Social Sciences

The small nation-state of Singapore has increasingly been referred to in the popular media as the Intelligent Island of the future. With significant state investment in the promotion and dissemination of information-communications technology and attendant social ramifications, this has become an area that can no longer be ignored or taken for granted. This article intends to map the conditions of possibility on which Singapore can be conceived of as an Intelligent Island, in situating the role of information technology and Intelligent Island discourse within the discourses of postcoloniality, technocapitalism, late modernity, and globalization. In particular, this article attempts to show …

Idmp-Based Fast Handoffs And Paging In Ip-Based Cellular Networks, Archan Misra, Subir Das, Ashutosh Dutta, Sajal K. Das May 2001

Idmp-Based Fast Handoffs And Paging In Ip-Based Cellular Networks, Archan Misra, Subir Das, Ashutosh Dutta, Sajal K. Das

Research Collection School Of Computing and Information Systems

We consider the use of our previously proposed Intra-Domain Mobility Management Protocol (IDMP) in fourth-generation mobile networks. On evaluating the heterogeneous access technologies, cellular layouts, and application characteristics of 4G environments, we realize a need to reduce both handoff latency and the frequency of mobility-related signaling. We first present IDMP's fast intradomain handoff mechanism that uses a duration-limited proactive packet multicasting solution. We quantify the expected buffering requirements of our proposed multicasting scheme for typical 4G network characteristics and compare it with alternative IP-based fast handoff solutions. We also present a paging scheme under IDMP that replicates the current cellular …

Is Feminism Bad For Multiculturalism?, Chandran Kukathas Apr 2001

Is Feminism Bad For Multiculturalism?, Chandran Kukathas

Research Collection School of Social Sciences

Multiculturalism and feminism are in tension to the extent that multiculturalism is a doctrine that condones the tolera- tion of cultural communities which might not respect or value women's concerns or interests. This has led some feminist think- ers, notably Susan Okin, to ask whether multiculturalism is bad for women. This paper agrees with Okin that there is a tension between feminism and multiculturalism - some of her critics to the contrary notwithstanding - but argues that multiculturalism should take preceden

Understanding The Assessment Center Process: Where Are We Now?, Filip Lievens, Richard J Klimoski Apr 2001

Understanding The Assessment Center Process: Where Are We Now?, Filip Lievens, Richard J Klimoski

Research Collection Lee Kong Chian School Of Business

Assessment centers have become widespread in Western Europe, Northern America, and Australia (Newell & Shackleton, 1994). The Task Force on Assessment Center Guidelines (1989) defined assessment centers as “a standardized evaluation of behavior based on multiple inputs. Multiple trained observers and techniques are used. Judgments about behaviors are made, in major part, from specifically developed assessment simulations. These judgments are pooled in a meeting among the assessors or by a statistical integration process” (p. 460).

Predictive Self-Organizing Networks For Text Categorization, Ah-Hwee Tan Apr 2001

Predictive Self-Organizing Networks For Text Categorization, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

This paper introduces a class of predictive self-organizing neural networks known as Adaptive Resonance Associative Map (ARAM) for classification of free-text documents. Whereas most sta- tistical approaches to text categorization derive classification knowledge based on training examples alone, ARAM performs supervised learn- ing and integrates user-defined classification knowledge in the form of IF-THEN rules. Through our experiments on the Reuters-21578 news database, we showed that ARAM performed reasonably well in mining categorization knowledge from sparse and high dimensional document feature space. In addition, ARAM predictive accuracy and learning efficiency can be improved by incorporating a set of rules derived from …

Tcp Hack: Tcp Header Checksum Option To Improve Performance Over Lossy Links, Rajesh Krishna Balan, Boon Peng Lee, Renjish Kumar, Jacob Lillykutty, Winston Seah, A. L. Ananda Apr 2001

Tcp Hack: Tcp Header Checksum Option To Improve Performance Over Lossy Links, Rajesh Krishna Balan, Boon Peng Lee, Renjish Kumar, Jacob Lillykutty, Winston Seah, A. L. Ananda

Research Collection School Of Computing and Information Systems

Wireless networks have become increasingly common and an increasing number of devices are communicating with each other over lossy links. Unfortunately, TCP performs poorly over lossy links as it is unable to differentiate the loss due to packet corruption from that due to congestion. We present an extension to TCP which enables TCP to distinguish packet corruption from congestion in lossy environments resulting in improved performance. We refer to this extension as the HeAder ChecKsum option (HACK). We implemented our algorithm in the Linux kernel and performed various tests to determine its effectiveness. Our results have shown that HACK performs …

District Magnitude, Electoral Formula, And The Number Of Parties, Kenneth Benoit Mar 2001

District Magnitude, Electoral Formula, And The Number Of Parties, Kenneth Benoit

Research Collection School of Social Sciences

Duverger's propositions concerning the psychologicaland mechanical consequences of electoral rules have previously beenexamined mainly through the lens of district magnitude,comparing the properties of single-member district pluralityelections with those of multimember proportional representationelections. The empirical consequences of multi-member plurality(MMP) rules, on the other hand, have received scant attention.Theory suggests that the effect of district magnitude on the numberand concentration of parties will differ with regard to whether theallocation rules are plurality-based or proportional. I test thistheory by drawing on a uniquely large-sample dataset where districtmagnitude and electoral formula vary but the basic universe ofpolitical parties is held constant, applying regression analysis …

Examining The Impact Of Destructive Acts In Marketing Channel Relationships, Jonathan D. Hibbard, Nirmalya Kumar, Lisa W. Stern Feb 2001

Examining The Impact Of Destructive Acts In Marketing Channel Relationships, Jonathan D. Hibbard, Nirmalya Kumar, Lisa W. Stern

Research Collection Lee Kong Chian School Of Business

In virtually all marketing channel relationships, one of the parties eventually will engage in an action that another channel member considers potentially destructive for the relationship. How a particular channel member reacts to such an act has implications for the long-term viability and success of the relationship. On the basis of a large data set collected from both a focal supplier and its independent dealers, the authors classify dealers' responses to a supplier's destructive acts by extending the response 'typology of exit, voice, and loyalty, which is based on Hirschman's seminal writings on responses to decline in organizations and states. …

Forecasting Volatility: Evidence From The German Stock Market, Hagen H. W. Bluhm, Jun Yu Feb 2001

Forecasting Volatility: Evidence From The German Stock Market, Hagen H. W. Bluhm, Jun Yu

Research Collection School Of Economics

In this paper we compare two basic approaches to forecast volatility in the German stock market. The first approach uses various univariate time series techniques while the second approach makes use of volatility implied in option prices. The time series models include the historical mean model, the exponentially weighted moving average (EWMA) model, four ARCH-type models and a stochastic volatility (SV) model. Based on the utilization of volatility forecasts in option pricing and Value-at-Risk (VaR), various forecast horizons and forecast error measurements are used to assess the ability of volatility forecasts. We show that the mode lrankings are sensitive to …

Social Logic As Business Logic: Guanxi, Trustworthiness And The Embeddedness Of Chinese Business Practices, Wai Keung Chung, Gary Hamilton Jan 2001

Social Logic As Business Logic: Guanxi, Trustworthiness And The Embeddedness Of Chinese Business Practices, Wai Keung Chung, Gary Hamilton

Research Collection School of Social Sciences

This chapter explores the nature of Chinese business practices by looking at their social foundations. We argue that the use of an inter-subjective logic based on the norms of social relationships provides an institutional foundation for economic transactions in Chinese business settings. The logic of social relationships-or what we call guanxi logic-is embedded in daily practices of the Chinese business community. Rather than making economic decisions less "economic", relational rules embedded in guanxi places interpersonal business transactions within a prescriptive framework, thereby increasing the calculability of economic outcomes. Guanxi logic is, therefore, a socially meaningful way to enhance economic rationality. …

Mentors Or Friends: Confucius And Aristotle On Equality And Ethical Development In Friendship, Sor-Hoon Tan Jan 2001

Mentors Or Friends: Confucius And Aristotle On Equality And Ethical Development In Friendship, Sor-Hoon Tan

Research Collection School of Social Sciences

In Thinking from the Han, David Hall and Roger Ames compare Plato's - and Confucius's views of friendship in relation to the question of transcendence and arrive at the sad conclusion that Socrates and Confucius could not be friends. "Socratic irony would not allow the inequality Confucius requires as a means of self-betterment. Confucius would not permit he and Socrates to hold all things in common." Along the way, they articulate an understanding of Confucius’ view of friendship as "a one-directional relationship in which one extends oneself by association with one who has attained a higher level of realization." Hall …

Psychological Mechanisms Underlying Individual Knowledge And Contribution In Learning Organizations, Bin Zhao, Hwee Hoon Tan Jan 2001

Psychological Mechanisms Underlying Individual Knowledge And Contribution In Learning Organizations, Bin Zhao, Hwee Hoon Tan

Research Collection Lee Kong Chian School Of Business

Although much has been written about how to set up learning organizations, there is a paucity of research on understanding employees’ willingness to learn or contribute knowledge in such activities, a key element in the success of organizational learning. This paper presents models for understanding individuals’ willingness to learn and individuals’ willingness to contribute in organizational settings. Through the examination of the psychological mechanisms underlying individuals’ willingness to learn and to contribute, we will further our understanding on the individual and contextual factors that affect employees’ decision to learn and contribute in organizational learning activities. Drawing from the literature, we …

Organizational Attractiveness For Prospective Applicants: A Person-Organisation Fit Perspective, Filip Lievens, Christoph Decaesteker, Pol Coetsier, Jo Geimaert Jan 2001

Organizational Attractiveness For Prospective Applicants: A Person-Organisation Fit Perspective, Filip Lievens, Christoph Decaesteker, Pol Coetsier, Jo Geimaert

Research Collection Lee Kong Chian School Of Business

This study investigates which of four objective organisational characteristics determine the attractiveness of organisations for prospective applicants and the degree to which the Big Five personality factors moderate the effects of some of these organisational attributes. To this end, 359 final-year students (engineering and business majors, 71% men, mean age = 22.4 years) read short descriptions of organisations. These descriptions varied on four organisational characteristics (i.e. organisation size, level of internationalisation, pay mix, and level of centralisation). The students had to indicate their attraction to the organisation. Additionally, they provided self-ratings on a personality inventory. The results show that prospective …

An Empirical Investigation Into Long- And Short-Term Indebtedness, Hing-Man Leung Jan 2001

An Empirical Investigation Into Long- And Short-Term Indebtedness, Hing-Man Leung

Research Collection School Of Economics

The external debt position of a country often lies at the heart of her financial crisis. While it is well-known that indebtedness and in particular a surge in short-term debts often precipitate a debt crisis that is often made worse by runs on a country’s foreign exchange, the reasons why a country takes a particular debt position is rarely formally explained. This paper investigates the long-term determinants of international indebtedness, the time-rates of change of indebtedness, and a nation’s short- to long term debt ratio. The data set used is the World Data CD-ROM. Six potential explanatory variables are: size, …

Probabilistic Principles In Unsupervised Learning Of Visual Structure: Human Data And A Model, Shimon Edelman, Benjamin P. Hiles, Hwajin Yang, Nathan Intrator Jan 2001

Probabilistic Principles In Unsupervised Learning Of Visual Structure: Human Data And A Model, Shimon Edelman, Benjamin P. Hiles, Hwajin Yang, Nathan Intrator

Research Collection School of Social Sciences

To find out how the representations of structured visual objects depend on the co-occurrence statistics of their constituents, we exposed subjects to a set of composite images with tight control exerted over (1) the conditional probabilities of the constituent fragments, and (2) the value of Barlow's criterion of "suspicious coincidence" (the ratio of joint probability to the product of marginals). We then compared the part verification response times for various probe/target combinations before and after the exposure. For composite probes, the speedup was much larger for targets that contained pairs of fragments perfectly predictive of each other, compared to those …

Evaluating Hungary's Mixed-Member Electoral System, Kenneth Benoit Jan 2001

Evaluating Hungary's Mixed-Member Electoral System, Kenneth Benoit

Research Collection School of Social Sciences

The electoral system adopted by Hungary in 1989 represents a monument to the potential for institutional design through bargaining to produce complex yet stable institutions. The key compromise reached during this bargaining process was the decision to use a mixed-member system, electing a roughly even number of representatives from both majoritarian single-seat districts (SSDs) and from multi-seat, list proportional representation (PR) districts. This decision established Eastern Europe's first mixed-member electoral system, a format that was to become common in post-communist electoral systems. In its ten-year existence, Hungary's mixed-member system has operated in three elections and seen three different governments come …

Education And Citizenship In Diverse Societies, Chandran Kukathas Jan 2001

Education And Citizenship In Diverse Societies, Chandran Kukathas

Research Collection School of Social Sciences

The question of the state's role in the control of sponsorship of education is addressed in the light of liberal political principles designed to keep peace and enforce toleration in culturally diverse societies. Some contemporary, self-described liberal philosophers argue for a much more substantial educational role for the state than liberal principles will really allow. Brian Barry's argument for that role assumes that the state can prescribe answers to controversial questions regarding the truth and the good life in which a truly liberal state would take no interest. Stephen Macedo is more accommodating to religious diversity than Barry, but his …

A Framework For Performance And Value Assessment Of E-Business Systems In Corporate Travel Distribution, A.M. Chircu, Robert J. Kauffman Jan 2001

A Framework For Performance And Value Assessment Of E-Business Systems In Corporate Travel Distribution, A.M. Chircu, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

This chapter proposes and illustrates a framework that the authors call the value life cycle for e-commerce systems. Based on recent research results that relate to technology investments in the corporate travel industry and related theoretical and empirical perspectives, the authors lay out the corporate travel e-commerce system solutions value life cycle. The perspective involves estimating the maximum value that that an organization can obtain by implementing an e-commerce system in a specific industry and competitive environment. It also considers multiple factors that act as value contingencies for the implementation process. These create barriers to value accrual and to …

Juror Comprehension And Complexity: Strategies To Enhance Understanding, Mark Findlay Jan 2001

Juror Comprehension And Complexity: Strategies To Enhance Understanding, Mark Findlay

Research Collection Yong Pung How School Of Law

Recent law reform debate proposes the complexity of trials as generally reducing juror comprehension. This in turn is said to impact on the accuracy of the verdict. The empirical studies of three very different jury systems examined in detail in the paper challenge these assumptions against problematic measures of complexity. Critics of the jury, particularly in commercial fraud trials, often take the issue of trial complexity as a given. The studies demonstrate that features of the trial which trouble jurors in terms of concentration, comprehension and decision making are consistent, while often specific to the trial and interrelated. The paper …

Rationalising Restitutionary Damages In Contract Law: An Elusive Or Illusory Ques, Andrew Phang, Pey Woan Lee Jan 2001

Rationalising Restitutionary Damages In Contract Law: An Elusive Or Illusory Ques, Andrew Phang, Pey Woan Lee

Research Collection Yong Pung How School Of Law

The present article surveys various issues in the law relating to the award of restitutionary damages in contract law, utilising as its point of focus the recent House of Lords decision in Attorney-General v Blake. It explores, in particular, two possible (albeit quite different) routes towards the recovery of such damages; the first based on the (more traditional) compensatory basis and the second on the (more controversial) restitutionary basis for disgorgement of the defendant's gain. While we argue that there is, on a more general level, no overriding objection in principle to the award of restitutionary damages for cynical breach …

The Statutory Derivative Action In Singapore: A Critical And Comparative Examination, Pearlie Koh Jan 2001

The Statutory Derivative Action In Singapore: A Critical And Comparative Examination, Pearlie Koh

Research Collection Yong Pung How School Of Law

As a mechanism for shareholder control of corporate wrongs and thus as a tool of corporate governance, the statutory derivative action has had much international attention given to it, particularly in the last 10 years. Singapore introduced its statutory derivative action in 1993 and since then, there have been two reported cases in which the action was invoked. In this paper, I consider the Singapore derivative action as contained in sections 216A and 216B of the Singapore Companies Act. The approach taken is a comparative one as I also look at the statutory derivative actions in Australia and other common …

Collaborative Model And Algorithms For Supporting Real-Time Distribution Logistics Systems, Hoong Chuin Lau, Qi Zhang Liu Dec 2000

Collaborative Model And Algorithms For Supporting Real-Time Distribution Logistics Systems, Hoong Chuin Lau, Qi Zhang Liu

Research Collection School Of Computing and Information Systems

We study a complex optimization problem that arises due to an emerging trend in distribution logistics. The problem involves the integration of an inventory management problem and the vehicle routing problem with time windows, both of which are known to be NP-hard. We describe a collaborative approach to solve this problem in real-time. The novelty of our approach lies in the tight algorithmic integration between two sub-problems, and suggests an elegant scheme to deal with other integrated optimization problems of the same nature. For first sub-problem, we will present two algorithms: a complete mathematical model integrating integer programming with constraint …

A Monte Carlo Investigation Of Some Tests For Stochastic Dominance, Yiu Kuen Tse, Xibin Zhang Dec 2000

A Monte Carlo Investigation Of Some Tests For Stochastic Dominance, Yiu Kuen Tse, Xibin Zhang

Research Collection School Of Economics

This paper compares the performance of several tests for stochastic dominance up to order three using Monte Carlo methods. The tests considered are the Davidson and Duclos (2000) test, the Anderson test (1996) and the Kaur, Rao and Singh (1994) test. We find that the Davidson-Duclos test appears to be the best. The Kaur-Rao-Singh test is overly conservative and does not compare favorably against the Davidson-Duclos and Anderson tests in terms of power.

An Efficient And Practical Scheme For Privacy Protection In E-Commerce Of Digital Goods, Feng Bao, Robert H. Deng, Peirong Feng Dec 2000

An Efficient And Practical Scheme For Privacy Protection In E-Commerce Of Digital Goods, Feng Bao, Robert H. Deng, Peirong Feng

Research Collection School Of Computing and Information Systems

It is commonly acknowledged that customers’ privacy in electronic commerce should be well protected. The solutions may come not only from the ethics education and legislation, but also from cryptographic technologies. In this paper we propose and analyze a privacy protection scheme for e-commerce of digital goods. The scheme takes cryptography as its technical means to realize privacy protection for online customers. It is efficient in both computational cost and communication cost. It is very practical for real e-commerce systems compared with previous solutions. The cryptographic technique presented in this paper is rather simple. But the scheme has great application …
