Developmental Financial Institutions As Technology Policy Instruments: Implications For Innovation And Entrepreneurship In Emerging Economies, Gerard George, Ganesh N. Prabhu Jan 2003

Developmental Financial Institutions As Technology Policy Instruments: Implications For Innovation And Entrepreneurship In Emerging Economies, Gerard George, Ganesh N. Prabhu

Research Collection Lee Kong Chian School Of Business

Developmental financial institutions (DFIs) in emerging economies regularly assess new technology platforms to support their investments in new ventures, established firms, and technology institutions (TIs). Their financing decisions are guided by national priorities such as achieving technological self-reliance. By providing attractive financing options and related support, DFIs are well placed to consciously channel finance into designated priority technology areas. To better understand DFI roles, we conducted multiple interviews with participants affiliated with DFIs, firms and TIs in India. From data gathered from these interviews and secondary data on DFIs in emerging economies, we develop a preliminary framework to suggest that …

Is Ricardo's Essay On Profits A Precursor Of The New Trade Theory?, Hian Teck Hoon Dec 2002

Is Ricardo's Essay On Profits A Precursor Of The New Trade Theory?, Hian Teck Hoon

Research Collection School Of Economics

This paper carefully analyzes a passage of Ricardo’s Essay on Profits ([1815] 1923), which suggests that he clearly understood the effects of both interindustry as well as intraindustry trade. In the context of the Essay model, Ricardo argues that free interindustry trade involving an exchange of manufactures for agricultural good (from England’s point of view) raises the rate of profit through lowering the relative price of the agricultural good. On the other hand, where trade involves simply an exchange of manufactures for manufactures, these being produced under conditions of economies of scale (division of labour in manufactures (pg. 25 of …

Situational Tests In Student Selection: An Examination Of Predictive Validity, Adverse Impact, And Construct Validity, Filip Lievens, Pol Coetsier Dec 2002

Situational Tests In Student Selection: An Examination Of Predictive Validity, Adverse Impact, And Construct Validity, Filip Lievens, Pol Coetsier

Research Collection Lee Kong Chian School Of Business

The Flemish Admission Exam 'Medical and Dental Studies' is comprised of four cognitive ability tests and four situational tests, namely two work samples (i.e., a lecture and a medical text) and two video-based situational judgement tests (i.e., a physician-patient interaction and a medical expert discussion). On the basis of the Admission Exam scores of 941 candidates (359 men, 582 women) this study shows that situational tests significantly can predict better than cognitive ability tests, with lecture and text emerging as significant predictors. When situational tests are combined with cognitive ability tests, there are no mean gender differences. Situational tests also …

Crystalclear: Active Visualization Of Association Rules, Hian-Huat Ong, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim Dec 2002

Crystalclear: Active Visualization Of Association Rules, Hian-Huat Ong, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Effective visualization is an important aspect of active data mining. In the context of association rules, this need has been driven by the large amount of rules produced from a run of the algorithm. To be able to address real user needs, the rules need to be summarized and organized so that it can be interpreted and applied in a timely manner. In this paper, we propose two visualization techniques that is an improvement over those used by existing data mining packages. In particular, we address the visualization of "differences" in the set of rules due to incremental changes in …

Vdl: A Language For Active Mining Variants Of Association Rules, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim Dec 2002

Vdl: A Language For Active Mining Variants Of Association Rules, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The popularity of association rules has resulted in several variations being proposed. In each case, additional attributes in the data are considered so as to produce more informative rules. In the context of active mining, different types of rules may be required over a period of time due to knowledge needs or the availability of new attributes. The present approach is the ad-hoc development of algorithms for each variant of rules. This is time consuming and costly, and is a stumping block to the vision of active mining. We argue that knowledge needs and the changing characteristics of the data …

Managing Project Uncertainty: From Variation To Chaos, Arnoud De Meyer, Christoph H. Loch, Michael T. Pich Dec 2002

Managing Project Uncertainty: From Variation To Chaos, Arnoud De Meyer, Christoph H. Loch, Michael T. Pich

Research Collection Lee Kong Chian School Of Business

The article cites a study finding that accurately gauging the degree of uncertainty inherent in the projects can help project managers quickly adapt to it. Researchers studied 16 projects in areas including personal-computer development, telecommunications, Internet startups, pharmaceutical development, iron-ore processing, airship development, and building construction, to examine risk management and project outcomes. They found that most managers failed to recognize that there are different types of uncertainty, each requiring a different management approach. This paper explores uncertainty-based management, which derives planning, monitoring and management style from an uncertainty profile comprising four types of uncertainty: variation, foreseen uncertainty, unforeseen uncertainty, …

A Data Mining Approach To Library New Book Recommendations, San-Yih Hwang, Ee Peng Lim Dec 2002

A Data Mining Approach To Library New Book Recommendations, San-Yih Hwang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

In this paper, we propose a data mining approach to recommending new library books that have never been rated or borrowed by users. In our problem context, users are characterized by their demographic attributes, and concept hierarchies can be defined for some of these demographic attributes. Books are assigned to the base categories of a taxonomy. Our goal is therefore to identify the type of users interested in some specific type of books. We call such knowledge generalized profile association rules. In this paper, we propose a new definition of rule interestingness to prune away rules that are redundant and …

Like Deja Vu All Over Again: The Hungarian Parliamentary Elections Of 2002, Kenneth Benoit Dec 2002

Like Deja Vu All Over Again: The Hungarian Parliamentary Elections Of 2002, Kenneth Benoit

Research Collection School of Social Sciences

On 7 and 21 April 2002, Hungary went to the polls to vote in its fourth competitive election since the transition to a multi-party system in 1989. Voting took place in two rounds, first on 7 April in 176 single-member districts and 20 proportional list districts, and then on 21 April in a run-off in the 131 single-member districts that had not yielded a majority candidate in the first round. The result was a surprise to nearly everyone. First, surpassing all expectations, turnout exceeded 70 per cent of the registered electorate, higher than in any previous election in Hungary. Second, …

The Culture Of Technology Of Singapore, Alwyn Lim Dec 2002

The Culture Of Technology Of Singapore, Alwyn Lim

Research Collection School of Social Sciences

The objective of this paper is to map the sociological context in which the cultural economy of technology of Singapore exists. Taking a socio-histori cal perspective, this paper argues that the development of Singapore as a technological 'intelligent island' must take centre stage in relation to the soci ological analysis of modern Singapore's political, economic, and socio-cultural structure. This involves a critique of theories of the information society and empirical research on East Asian developmental states. The aim is to chart the development of technology in Singapore, from its founding as a colonial port-city to its current status as an …

Survey Article: Multiculturalism As Fairness: Will Kymlicka's Multicultural Citizenship, Chandran Kukathas Dec 2002

Survey Article: Multiculturalism As Fairness: Will Kymlicka's Multicultural Citizenship, Chandran Kukathas

Research Collection School of Social Sciences

According to Will Kymlicka's book Multicultural Citizenship: A Liberal Theory of Minority Rights, `the liberal ideal is a society of free and equalindividuals'.1 But what, he goes on to ask, is the relevant `society'? The answer he says most people would give is `their nation'. `The sort of freedom and equality they most value, and can make use of is freedom and equality within their own societal culture'. Indeed, most people `are willing to forgo a wider freedom and equality to ensure the continued existence of their nation' (93). Thus few favour open borders which allow people freely to settle, …

Semantic Exploration Of Lecture Videos, Edward Altman, Yu Chen, Wai Chong Low Dec 2002

Semantic Exploration Of Lecture Videos, Edward Altman, Yu Chen, Wai Chong Low

Research Collection School Of Computing and Information Systems

E-Learning is rapidly changing the way that universities and corporations offer education and training. In recent years, the acquisition and distribution of rich media content has been largely automated, However, existing applications are functionally and visually static and remain organized around the delivery media, rather than the knowledge representation and learning tasks of the student. The innovative approach of this system is the extraction of semantically meaningful structures in the lecture combined with text analysis to support task based queries. In this demonstration we will show this combination of pedagogical and content descriptions leads to novel forms of visualization and …

A Model Of Industrialization And International Wage Convergence Based On Multi-Plant Foreign Direct Investment, Hian Teck Hoon, Irene Ng Dec 2002

A Model Of Industrialization And International Wage Convergence Based On Multi-Plant Foreign Direct Investment, Hian Teck Hoon, Irene Ng

Research Collection School Of Economics

We show that for industrialization and international wage convergence through multi-plant foreign direct investment (FDI) to occur, the measure of the quality of the social infrastructure in the South relative to that in the North must be at least as large as the South-North wage ratio. We also show that if profitable FDI flows already take place from the North to the most productive economy in the South, then less productive Southern economies can also become recipients of FDI, provided that they are integrated into the world trading system, and there are no impediments to the decline of their wage …

Residual-Based Diagnostics For Conditional Heteroscedasticity Models, Yiu Kuen Tse Dec 2002

Residual-Based Diagnostics For Conditional Heteroscedasticity Models, Yiu Kuen Tse

Research Collection School Of Economics

We examine the residual–based diagnostics for univariate and multivariate conditional heteroscedasticity models. The tests are based on the parameter estimates of an autoregression with the squared standardized residuals or the cross products of the standardized residuals as dependent variables. As the regression involves estimated regressors the standard distribution theories of the ordinary least squares estimates do not apply. We provide the asymptotic variance of the regression estimates. Diagnostic statistics, which are asymptotically distributed as ?[sup 2], are constructed. A Monte Carlo experiment is conducted to investigate the finite–sample properties of the residual–based tests for both univariate and multivariate models. The …

On Clustering And Retrieval Of Video Shots Through Temporal Slices Analysis, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang Dec 2002

On Clustering And Retrieval Of Video Shots Through Temporal Slices Analysis, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang

Research Collection School Of Computing and Information Systems

Based on the analysis of temporal slices, we propose novel approaches for clustering and retrieval of video shots. Temporal slices are a set of two-dimensional (2-D) images extracted along the time dimension of an image volume. They encode rich set of visual patterns for similarity measure. In this paper, we first demonstrate that tensor histogram features extracted from temporal slices are suitable for motion retrieval. Subsequently, we integrate both tensor and color histograms for constructing a two-level hierarchical clustering structure. Each cluster in the top level contains shots with similar color while each cluster in bottom level consists of shots …

Motion Retrieval By Temporal Slices Analysis, Chong-Wah Ngo, Chong-Wah Ngo, Hong-Jiang Zhang Dec 2002

Motion Retrieval By Temporal Slices Analysis, Chong-Wah Ngo, Chong-Wah Ngo, Hong-Jiang Zhang

Research Collection School Of Computing and Information Systems

In this papel; we investigate video shots retrieval based on the analysis of temporal slice images. Temporal slices are a set of2D images extracted along the time dimension of image sequences. They encode rich set of motion clues for shot similarity measure. Because motion is depicted as texture orientation in temporal slices, we utilize various texture features such as tensor histogram, Gabor feature, and the statistical feature of co-occurrence matrix extracted directly from slices for motion description and retrieval. In this way, motion retrieval can be treated in a similar way as texture retrieval problem. Experimental results indicate that the …

Legal Environment For Technology Transfer In Taiwan, Kung-Chung Liu Dec 2002

Legal Environment For Technology Transfer In Taiwan, Kung-Chung Liu

Research Collection Yong Pung How School Of Law

In an effort to become an industrialized country, Taiwan, the Republic of China (ROC) has relied heavily on technology transfers and investment from abroad. The Taiwanese government adopted a heavy-handed policy of regulating investments made by foreigners and overseas Chinese in 1954. These policies include the Foreigner Investment Act (FIA) and the Overseas Chinese Investment Act (OCIA), which require all foreigners and overseas Chinese to obtain the Ministry of Economic Affairs (MOEA) approval prior to making any investments.1 Such investments may also be in the form of patents, trademarks, copyright, know-how, and other intellectual property (IP).2 In 1962, the Technology …

The Choice Between Joint Venture And Wholly Owned Subsidiary: An Institutional Perspective, Daphne W. Yiu, Shige Makino Nov 2002

The Choice Between Joint Venture And Wholly Owned Subsidiary: An Institutional Perspective, Daphne W. Yiu, Shige Makino

Research Collection Lee Kong Chian School Of Business

The study of foreign entry-mode choice has been based almost exclusively on transaction-cost theory. This theory focuses mainly on the impacts of firm- and industry-specific factors on the choice of entry mode, taking the effects of country-specific contextual factors as constant or less important. In contrast, the institutional perspective emphasizes the importance of the influence of both institutional forces embedded in national environments and decision makers' cognitive constraints on the founding conditions of new ventures. Still, this theoretical perspective has yet to provide insights into how institutional factors influence the choice of foreign entry mode. The primary goal of the …

Dynamical Evolutionary Psychology: Mapping The Domains Of The New Interactionist Paradigm, Douglas T. Kenrick, Jon K. Maner, Jon Butner, Norman P. Li, D. Vaughn Becker, Mark Schaller Nov 2002

Dynamical Evolutionary Psychology: Mapping The Domains Of The New Interactionist Paradigm, Douglas T. Kenrick, Jon K. Maner, Jon Butner, Norman P. Li, D. Vaughn Becker, Mark Schaller

Research Collection School of Social Sciences

Dynamical systems and evolutionary theories have both been proposed as integrative approaches to psychology. These approaches are typically applied to different sets of questions. Dynamical systems models address the properties of psychological systems as they emerge and change over time; evolutionary models address the specific functions and contents of psychological structures. New insights can be achieved by integrating these two paradigms, and we propose a framework to begin doing so. The framework specifies a set of six evolutionarily fundamental social goals that place predictable constraints on emergent processes within and between individuals, influencing their dynamics over the short-term, and across …

Defending Against Redirect Attacks In Mobile Ip, Robert H. Deng, Jianying Zhou, Feng Bao Nov 2002

Defending Against Redirect Attacks In Mobile Ip, Robert H. Deng, Jianying Zhou, Feng Bao

Research Collection School Of Computing and Information Systems

The route optimization operation in Mobile IP Version 6 (MIPv6) allows direct routing from any correspondent node to any mobile node and thus eliminates the problem of "triangle routing" present in the base Mobile IP Version 4 (MIPv4) protocol. Route optimization, however, requires that a mobile node constantly inform its correspondent nodes about its new care-of addresses by sending them binding update messages. Unauthenticated or malicious binding updates open the door for intruders to perform redirect attacks, i.e., malicious acts which redirect traffic from correspondent nodes to locations chosen by intruders. How to protect binding update messages to defend against …

Predicting Bottleneck Bandwidth Sharing By Generalized Tcp Flows, Archan Misra, Teunis Ott, John Baras Nov 2002

Predicting Bottleneck Bandwidth Sharing By Generalized Tcp Flows, Archan Misra, Teunis Ott, John Baras

Research Collection School Of Computing and Information Systems

The paper presents a technique for computing the individual throughputs and the average queue occupancy when multiple TCP connections share a single bottleneck buffer. The bottleneck buffer is assumed to perform congestion feedback via randomized packet marking or drops. We first present a fixed point-based analytical technique to compute the mean congestion window sizes, the mean queue occupancy and the individual throughputs when the TCP flows perform idealized congestion avoidance. We subsequently extend the technique to analyze the case where TCP flows perform generalized congestion avoidance and demonstrate the use of this technique under the Assured Service model, where each …

The Capacity Of Multi-Hop Wireless Networks With Tcp Regulated Traffic, Sorav Bansal, Rajeev Shorey, Shobhit Chugh, Anurag Goel, Kapil Kumar, Archan Misra Nov 2002

The Capacity Of Multi-Hop Wireless Networks With Tcp Regulated Traffic, Sorav Bansal, Rajeev Shorey, Shobhit Chugh, Anurag Goel, Kapil Kumar, Archan Misra

Research Collection School Of Computing and Information Systems

We study the dependence of the capacity of multi-hop wireless networks on the transmission range of nodes in the network with TCP regulated traffic. Specifically, we examine the sensitivity of the capacity to the speed of the nodes and the number of TCP connections in an ad hoc network. By incorporating the notion of a minimal acceptable QoS metric (loss) for an individual session, we argue that the QoS-aware capacity is a more accurate model of the TCP-centric capacity of an ad-hoc network. We study the dependence of capacity on the source application (Telnet or FTP) and on the choice …

Lay Theories And Evaluation-Based Organization Of Impressions: An Application Of The Memory Search Paradigm, Yuk-Yue Tong, Chi-Yue Chiu Nov 2002

Lay Theories And Evaluation-Based Organization Of Impressions: An Application Of The Memory Search Paradigm, Yuk-Yue Tong, Chi-Yue Chiu

Research Collection School of Social Sciences

People may believe that personal attributes are fixed entities that cannot be changed (hold an entity theory). Alternatively, they may believe that qualities of a person are malleable (hold an incremental theory). In the present research, the authors used Sternberg's (1966) memory search task to examine entity and incremental theorists' cognitive strategies in memory search. It was hypothesized that entity theorists, who have a greater tendency to make spontaneous evaluation of people, would organize impressions in short-term memory according to whether the stimulus persons are positively or negatively evaluated. Next, they might compare the probe only to the stimulus persons …

Web Classification Using Support Vector Machine, Aixin Sun, Ee Peng Lim Nov 2002

Web Classification Using Support Vector Machine, Aixin Sun, Ee Peng Lim

Research Collection School Of Computing and Information Systems

In web classification, web pages from one or more web sites are assigned to pre-defined categories according to their content. Since web pages are more than just plain text documents, web classification methods have to consider using other context features of web pages, such as hyperlinks and HTML tags. In this paper, we propose the use of Support Vector Machine (SVM) classifiers to classify web pages using both their text and context feature sets. We have experimented our web classification method on the WebKB data set. Compared with earlier Foil-Pilfs method on the same data set, our method has been …

A Visual Tool For Building Logical Data Models Of Websites, Zehua Liu, Wee-Keong Ng, Feifei Li, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Information sources over the WWW contain a large amount of data organized according to different interests and values. Thus, it is important that facilities are there to enable users to extract information of interest in a simple and effective manner. To do this, We propose the Wiccap Data Model, an XML data model that maps Web information sources into commonly perceived logical models, so that information can be extracted automatically according to users' interests. To accelerate the creation of data models, we have implemented a visual tool, called the Mapping Wizard, to facilitate and automate the process of producing Wiccap …
