Community Banking In The E-Business Era, Peter Southard, Keng Siau Jan 2002

Community Banking In The E-Business Era, Peter Southard, Keng Siau

Research Collection School Of Computing and Information Systems

This paper reviews how existing and potential uses of Internet technology can generate a competitive advantage for rural community banks. To do so, it offers a framework for analyzing Internet technology investment decisions. Organizations in this segment of the banking industry are often more removed from centers of technology and have traditionally been more conservative in their approaches to information technology (among other things). Banking Associations have developed in the U.S., such as the Independent Bankers Association, to try and help community banks coordinate marketing, legislative, and other issues that they have in common. The use of Internet technology can …

Enhancing Profiles For Anomaly Detection Using Time Granularities, Yingjiu Li, Ningning Wu, X. Sean Wang, Sushil Jajodia Jan 2002

Enhancing Profiles For Anomaly Detection Using Time Granularities, Yingjiu Li, Ningning Wu, X. Sean Wang, Sushil Jajodia

Research Collection School Of Computing and Information Systems

Recently, association rules have been used to generate profiles of normal behavior for anomaly detection. However, the time factor (especially in terms of multiple time granularities) has not been utilized extensively in generation of these profiles. In reality, user behavior during different time intervals may be very different. For example, the normal number and duration of FTP connections may vary from working hours to midnight, from business day to weekend or holiday. Furthermore, these variations may depend on the day of the month or the week. This paper proposes to build profiles using temporal association rules in terms of multiple …

Scale-Invariant Behavior In A Spatial Game Of Prisoners’ Dilemma, Yun Fong Lim, Kan Chen, Ciriyam Jayaprakash Jan 2002

Scale-Invariant Behavior In A Spatial Game Of Prisoners’ Dilemma, Yun Fong Lim, Kan Chen, Ciriyam Jayaprakash

Research Collection Lee Kong Chian School Of Business

A spatially extended version of the game of prisoner’s dilemma, originally proposed by Nowak and May, is modified to include stochastic updating and found to exhibit scale-invariant behavior. Two critical regimes with different scaling behaviors are found; the corresponding exponents have been determined numerically. Spatially, the critical states are characterized by the existence of delicately balanced networks of defectors separating domains of cooperators; temporally, the evolution of the critical states following local perturbations is characterized by avalanches of various magnitudes, which cause restructuring of the networks of defectors on all scales.

Purpose: A specific TLS-CHOP fusion gene resulting from the t(12;16) is present in at least 95% of myxoid liposarcomas (MLS). Three common forms of the TLS-CHOP fusion have been described, differing by the presence or absence of TLS exons 6-8 in the fusion product. Type 5-2 (also known as type II) consists of TLS exons 1-5 fused to CHOP exon 2; type 7-2 (also known as type I) also includes TLS exons 6 and 7 in the fusion, whereas type 8-2 (also known as type III) fuses TLS exons 1-8 to CHOP exon 2. We sought to determine the impact …

Scripted Thought: Processing Korean Hancha And Hangul In A Multimedia Context, Nader T. Tavassoli, Jin K. Han Dec 2001

Scripted Thought: Processing Korean Hancha And Hangul In A Multimedia Context, Nader T. Tavassoli, Jin K. Han

Research Collection Lee Kong Chian School Of Business

We compare the cognitive processing of words written in alphabetic scripts with the cognitive processing of words written in logographic scripts. We suggest that the processing of words written in alphabetic scripts relies more heavily on the storage of--and the serial rehearsal properties of--short-term memory's phonological loop. In contrast, the processing of words written in logographic scripts relies more on the storage of--and the spatial-relational rehearsal properties of--visual short-term memory. A series of three experiments investigates implications of these processing differences within a single language, Korean, where words can be written in the alphabetic Hangul or in the logographic Han-cha. …

Dimension And Exercise Variance In Assessment Center Scores: A Large-Scale Evaluation Of Multitrait-Multimethod Studies, Filip Lievens, James M. Conway Dec 2001

Dimension And Exercise Variance In Assessment Center Scores: A Large-Scale Evaluation Of Multitrait-Multimethod Studies, Filip Lievens, James M. Conway

Research Collection Lee Kong Chian School Of Business

This study addresses 3 questions regarding assessment center construct validity: (a) Are assessment center ratings best thought of is reflecting dimension constructs (dimension model). exercises (exercise model). or a combination? (b) To what extent do dimensions or exercises account for variance? (c) Which design characteristics increase dimension variance? To this end, a large set of multitrait-multimethod studies (N = 34) were analyzed, showing that assessment center ratings were best represented (i.e., in terms of fit and admissible solutions) by a model with correlated dimensions and exercises specified a correlated uniquenesses. In this model, dimension variance equals exercise variance. Significantly more …

Management Research On Fashion: A Review And Evaluation, Timothy Adrian Robert Clark

Research Collection Lee Kong Chian School Of Business

In recentyears there has been growing interest and debate amongst scholars with respectto the notion that management ideas are subject to recurrent swings in fashionin the same way that aesthetic aspects of life, such as clothing styles andmusical tastes, are characterized by surges of popularity and then decline. A numberof reasons for the increasing importance of management fashion as an area ofresearch have been identified. First, each wave of fashionable thinking inmanagement is seen as altering accepted definitions of the character of themodern organizational ideal with the consequence that few people who work inorganizations remain untouched by the consequence of …

Discrete Singular Convolution For The Prediction Of High Frequency Vibration Of Plates, Yibao Zhao, G. W. Wei, Y. Xiang Dec 2001

Discrete Singular Convolution For The Prediction Of High Frequency Vibration Of Plates, Yibao Zhao, G. W. Wei, Y. Xiang

Research Collection Lee Kong Chian School Of Business

Theoretical analysis of high frequency vibrations is indispensable in a variety of engineering designs. Much effort has been made on this subject in the past few decades. However, there is no single technique which can be applied with confidence to various engineering structures for high frequency predictions at present. This paper introduces a novel computational approach, the discrete singular convolution (DSC) algorithm, for high frequency vibration analysis of plate structures. Square plates with six distinct boundary conditions are considered. To validate the proposed method, a completely independent approach, the Levy method, is employed to provide exact solutions for a comparison. …

Assessors' Use Of Personality Traits In Descriptions Of Assessment Centre Candidates: A Five-Factor Model Perspective, Filip Lievens, Filip De Fruyt, Karen Van Dam Dec 2001

Assessors' Use Of Personality Traits In Descriptions Of Assessment Centre Candidates: A Five-Factor Model Perspective, Filip Lievens, Filip De Fruyt, Karen Van Dam

Research Collection Lee Kong Chian School Of Business

In assessment centres assessors are typically taught to note down behavioural observations. However, previous studies have shown that about 20% of assessor notes contain trait descriptors. Instead of regarding these descriptors as errors, this study examines their position in a personality descriptive taxonomy (i.e. the AB5C taxonomy, see Hofstee, De Raad, & Goldberg, 1992) and relates them to employment recommendations. To this end, assessor notes of 403 assessees (214 men, 189 women; mean age 33 years) were scrutinized for personality descriptors. Results show that assessors, as a group, use descriptors referring to all five personality domains with a preference for …

Factor Substitution And Endogenous Growth, Hing-Man Leung Dec 2001

Factor Substitution And Endogenous Growth, Hing-Man Leung

Research Collection School Of Economics

We argue that the degree of substitutability between skilled and unskilled workers in production increases long-term income growth rate. Growth rate reaches its maximum when such factors are perfect substitutes, but falls to zero when they are perfect complements. This model brings together the diverging relative wage and the human-capital-growth literature. Easier substitution absorbs more workers into the skilled profession, and their training fuels human capital accumulation and growth. Our result implies, among other things, that growth is positively related to between-and within-group inequality.

Research Collection Lee Kong Chian School Of Business

Global airline strategic alliances have emerged since the late 1980s, and their number has slowly risen through the years. Will the number of such alliances continue to proliferate? Or will airlines consolidate with one another to form mega-carriers? In this paper, the likelihood of various airline consolidation and alliance development possibilities was examined based on a number of high-level trends and forces. The most probable near-term industry alliance and consolidation structure is described, accompanied with a probable path of evolution. These predictions have important implications for managers of strategic alliances, carriers who are currently in an alliance as well as …

Privacy Protection For Transactions Of Digital Goods, Feng Bao, Robert H. Deng Nov 2001

Privacy Protection For Transactions Of Digital Goods, Feng Bao, Robert H. Deng

Research Collection School Of Computing and Information Systems

In this paper we study the problem of how to protect users’ privacy in web transactions of digital goods. In particular, we introduce a system which allows a user to disclose his/her identity information (such as user account or credit card number) to a web site in exchange for a digital item, but prevents the web site from learning which specific item the user intends to obtain. The problem concerned here is orthogonal to the problem of anonymous transactions [RSG98], [RR98] but commensurate with the general problem of PIR (private information retrieval) [CGK95]

Foskett V. Mckeown – Hard-Nosed Property Rights Or Unjust Enrichment?, Hang Wu Tang Nov 2001

Foskett V. Mckeown – Hard-Nosed Property Rights Or Unjust Enrichment?, Hang Wu Tang

Research Collection Yong Pung How School Of Law

The recent judgment of the House of Lords in Foskett is extremely important as it straddles insurance law, property law, tracing and unjust enrichment. First, it establishes the proposition that it is possible to trace misappropriated moneys wrongfully paid as premiums into the proceeds of a policy. Second, two of the Law Lords contemplated the abolition of the distinction between the rules for tracing in law and tracing in equity. Third, the judgments of the Law Lords contain valuable guidance as to the context in which equitable ownership and the law of unjust enrichment should be viewed.

Pickup And Delivery Problem With Time Windows: Algorithms And Test Case Generation, Hoong Chuin Lau, Zhe Liang

Research Collection School Of Computing and Information Systems

In the pickup and delivery problem with time windows (PDPTW), vehicles have to transport loads from origins to destinations respecting capacity and time constraints. In this paper, we present a two-phase method to solve the PDPTW. In the first phase, we apply a novel construction heuristics to generate an initial solution. In the second phase, a tabu search method is proposed to improve the solution. Another contribution of this paper is a strategy to generate good problem instances and benchmarking solutions for PDPTW, based on Solomon's benchmark test cases for VRPTW. Experimental results show that our approach yields very good …

On Clustering And Retrieval Of Video Shots, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang Oct 2001

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

Research Collection School Of Computing and Information Systems

Clustering of video data is an important issue in video abstraction, browsing and retrieval. In this paper, we propose a two-level hierarchical clustering approach by aggregating shots with similar motion and color features. Motion features are computed directly from 20 tensor histograms, while color features are represented by 30 color histograms. Cluster validity analysis is further applied to automatically determine the number of clusters at each level. Video retrieval can then be done directly based on the result of clustering. The proposed approach is found to be useful particularly for sports games, where motion and color are important visual cues …

The Construct Validity Of A Belgian Assessment Centre: A Comparison Of Different Models, Filip Lievens, Etienne Van Keer Sep 2001

The Construct Validity Of A Belgian Assessment Centre: A Comparison Of Different Models, Filip Lievens, Etienne Van Keer

Research Collection Lee Kong Chian School Of Business

This study investigates the construct validity of a Belgian assessment centre through a comprehensive set of confirmatory factor analysis models. In particular, the general confirmatory factor analysis approach as well as the correlated uniqueness approach are fitted to the same data. Results replicate Sagie and Magnezy's (1997) finding that the correlated uniqueness model is appropriate to represent exercise effects in assessment centres, as a good fit and no estimation problems are obtained. In this model the dimensions explain 36% of variance, revealing evidence of convergent validity. Possibly, this is due to the careful design of this assessment centre. Evidence of …

The Effects Of Alliance Portfolio Characteristics And Absorptive Capacity On Performance: A Study Of Biotechnology Firms, Gerard George, Shaker A. Zahra, Kathleen K. Wheatley, Raihan Khan Sep 2001

The Effects Of Alliance Portfolio Characteristics And Absorptive Capacity On Performance: A Study Of Biotechnology Firms, Gerard George, Shaker A. Zahra, Kathleen K. Wheatley, Raihan Khan

Research Collection Lee Kong Chian School Of Business

In many high technology industries, strategic alliances have become important for improving a firm's financial performance by providing knowledge that can be used to develop the capabilities needed to introduce new products. Therefore, researchers have examined those characteristics of alliances that can contribute to the performance of high technology companies. There is agreement that the structure and knowledge flows within alliances can affect a firm's innovativeness. However, to date, researchers have studied alliances as individual events or transactions, failing to recognize their synergistic effects as a coherent portfolio. Viewing alliances as a portfolio of strategic agreements, we suggest that portfolio …

Consumer Decision Making In A Multi-Generational Choice Set Context, Namwoon Kim, Rajendra K. Srivastava, Jin K. Han Sep 2001

Consumer Decision Making In A Multi-Generational Choice Set Context, Namwoon Kim, Rajendra K. Srivastava, Jin K. Han

Research Collection Lee Kong Chian School Of Business

Most new product adoption models have focused on single-generation products. Only recently have researchers begun to focus on the importance of analyzing consumers' purchase demands in multi-generation products. This paper proposes a model that incorporates both initial and repeat purchases and allows for leap-frogging behavior for multi-generation technological products. Whereas most new product adoption models are based on aggregate market sales, the proposed model is estimated and validated on individual consumer data. Within a logistical modeling framework, the model combines a purchase incidence (buy/not buy) component and generation choice components for each time period. These model components allow for individual …

Exploiting Image Indexing Techniques In Dct Domain, Chong-Wah Ngo, Ting-Chuen Pong, Ronald T. Chin Sep 2001

Exploiting Image Indexing Techniques In Dct Domain, Chong-Wah Ngo, Ting-Chuen Pong, Ronald T. Chin

Research Collection School Of Computing and Information Systems

This paper is concerned with the indexing and retrieval of images based on features extracted directly from the JPEG discrete cosine transform (DCT) domain. We examine possible ways of manipulating DCT coefficients by standard image analysis approaches to describe image shape, texture, and color. Through the Mandala transformation, our approach groups a subset of DCT coefficients to form ten blocks. Each block represents a particular frequency content of the original image. Two blocks are used to model rough object shape; nine blocks to describe subband properties; and one block to compute color distribution. As a result, the amount of data …

The Integration Of The East And South-East Asian Equity Markets, K. B. Tan, Yiu Kuen Tse Sep 2001

The Integration Of The East And South-East Asian Equity Markets, K. B. Tan, Yiu Kuen Tse

Research Collection School Of Economics

This study examines how the degree of capital-market integration of the East and South-East Asian (ESEA) economies varied over the period 1988–2000 following the deregulation of these markets. The deregulation process varied across the countries both in terms of intensity and timing. A greater degree of co-movements in stock prices is a reflection of greater stock-market integration. We employ Geweke’s (1982) measure of feedback for different pairs of markets. For each pair of markets, the Geweke measure shows how co-movements in daily returns of stock prices varied over time. This is followed by the vector autoregression (VAR) analysis to examine …
