Religion And Technology: Refiguring Place, Space, Identity And Community, Lily Kong
Religion And Technology: Refiguring Place, Space, Identity And Community, Lily Kong
Research Collection School of Social Sciences
This paper reviews the literature on the religion-technology nexus, drawing up a research agenda and offering preliminary empirical insights. Firsts I stress the need to explore the new politics of space as a consequence of technological development, emphasizing questions about the role of religion in effecting a form of religious (neo)imperialism, and uneven access to techno-religious spaces. Second, I highlight the need to examine the politics of identity and community, since cyberspace is not an isotropic surface. Third, I underscore the need to engage with questions about the poetics of religious community as social relations become mediated by technology. Finally, …
Automated Online News Classification With Personalization, Chee-Hong Chan, Aixin Sun, Ee Peng Lim
Automated Online News Classification With Personalization, Chee-Hong Chan, Aixin Sun, Ee Peng Lim
Research Collection School Of Computing and Information Systems
Classification of online news, in the past, has often been done manually. In our proposed Categorizor system, we have experimented an automated approach to classify online news using the Support Vector Machine (SVM). SVM has been shown to deliver good classification results when ample training documents are given. In our research, we have applied SVM to personalized classification of online news.
From Common Law To Civil Law Jurisdictions: Court Adr On The Move In Germany, Nadja Alexander
From Common Law To Civil Law Jurisdictions: Court Adr On The Move In Germany, Nadja Alexander
Research Collection Yong Pung How School Of Law
In Australia today, ADR processes are recognised not only as a distinct system of dispute resolution, but also as a system that interacts interdependently with the legal system. This is most clearly demonstrated in the context of court-related mediation, which is increasingly seen as an effective way to increase access to, participation in, and satisfaction with the way legal disputes are resolved. Cappelletti categorises ADR as the third wave in the worldwide access-to-justice movement. ADR provides a different approach and a different sort of justice for solving disputes — what Cappelletti labels ‘co-existential justice’.
Factor Substitution And Endogenous Growth, Hing-Man Leung
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.
Characteristics Of Erp Software Maintenance: A Multiple Case Study, Fiona Fui-Hoon Nah, Silvana Faja, Teuta Cata
Characteristics Of Erp Software Maintenance: A Multiple Case Study, Fiona Fui-Hoon Nah, Silvana Faja, Teuta Cata
Research Collection School Of Computing and Information Systems
A multiple case study approach was employed to identify maintenance activities pertaining to enterprise resource planning (ERP) implementation, classify them into maintenance categories, and assess their relative frequency at various stages of the ERP maintenance lifecycle. Five maintenance categories (corrective, adaptive, perfective, preventive, user support) were identified from a review of the literature on software maintenance. A new category pertaining to ‘communication, coordination and knowledge exchange with external parties’ and herein labeled ‘external parties’ is introduced to highlight the supporting role of external parties in ERP maintenance. This category includes reporting problems to vendors and consultants, tracking their progress towards …
Persistence In Style-Adjusted Mutual Fund Returns, Melvyn Teo, Sung-Jun Woo
Persistence In Style-Adjusted Mutual Fund Returns, Melvyn Teo, Sung-Jun Woo
Research Collection Lee Kong Chian School Of Business
The literature on mutual fund persistence took a hit with the finding that one-year stock momentum and expense ratios account for most of the persistence in mutual fund performance (Carhart, 1992; Carhart, 1997). However, since equity mutual funds are grouped into styles (e.g., large value, small growth, mid-cap growth, etc.) and are often confined to trading stocks within their style, one should measure fund performance relative to style when investigating managerial ability. Using CRSP mutual fund data and a methodology similar to Carhart (1997), we find that differences in style-adjusted fund returns persist for up to six years. Neither one-year …
Evolution Of Global Airline Strategic Alliance And Consolidation In The Twenty-First Century, Terence P. C. Fan, Laurence Vigeant-Langlois, Christine Geissler, Björn Bosler, Jan Wilmking
Evolution Of Global Airline Strategic Alliance And Consolidation In The Twenty-First Century, Terence P. C. Fan, Laurence Vigeant-Langlois, Christine Geissler, Björn Bosler, Jan Wilmking
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 …
Foskett V. Mckeown – Hard-Nosed Property Rights Or Unjust Enrichment?, Hang Wu Tang
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.
Hierarchical Text Classification And Evaluation, Aixin Sun, Ee Peng Lim
Hierarchical Text Classification And Evaluation, Aixin Sun, Ee Peng Lim
Research Collection School Of Computing and Information Systems
Hierarchical Classification refers to assigning of one or more suitable categories from a hierarchical category space to a document. While previous work in hierarchical classification focused on virtual category trees where documents are assigned only to the leaf categories, we propose atop-down level-based classification method that can classify documents to both leaf and internal categories. As the standard performance measures assume independence between categories, they have not considered the documents incorrectly classified into categories that are similar or not far from the correct ones in the category tree. We therefore propose the Category-Similarity Measures and Distance-Based Measures to consider the …
Privacy Protection For Transactions Of Digital Goods, Feng Bao, Robert H. Deng
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]
Pickup And Delivery Problem With Time Windows: Algorithms And Test Case Generation, Hoong Chuin Lau, Zhe Liang
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 …

Foci: Flexible Organizer For Competitive Intelligence, Hwee-Leng Ong, Ah-Hwee Tan, Jamie Ng, Hong Pan, Qiu-Xiang Li
Research Collection School Of Computing and Information Systems
This paper describes how an integrated web-based application, code-named FOCI (Flexible Organizer for Competitive Intelligence), can help the knowledge worker in the gathering, organizing, tracking, and dissemination of competitive intelligence or knowledge bases on the web. It shows how text mining techniques including a novel user-configurable clustering, trend analysis and visualization techniques can be used synergistically to address the problem of managing information gathered from the web. FOCI allows a user to define and personalize the organization of the information clusters according to their needs and preferences into portfolios. Predefined sections for organizing information in specific domains is also supported. …
Modeling And Simulation Of Steady State And Transient Behaviors For Emergent Socs, Joann M. Paul, Arne Suppe, Donald E. Thomas
Modeling And Simulation Of Steady State And Transient Behaviors For Emergent Socs, Joann M. Paul, Arne Suppe, Donald E. Thomas
Research Collection School Of Computing and Information Systems
We introduce a formal basis for viewing computer systems as mixed steady state and non-steady state (transient) behaviors to motivate novel design strategies resulting from simultaneous consideration of function, scheduling and architecture. We relate three design styles: Hierarchical decomposition, static mapping and directed platform that have traditionally been separate. By considering them together, we reason that once a steady state system is mapped to an architecture, the unused processing and communication power may be viewed as a platform for a transient system, ultimately resulting in more effective design approaches that ease the static mapping problem while still allowing for effective …
On Clustering And Retrieval Of Video Shots, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang
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 …
Jointly Coordinating Ecn And Tcp For Rapid Adaptation To Varying Bandwidth, Archan Misra, Teunis Ott
Jointly Coordinating Ecn And Tcp For Rapid Adaptation To Varying Bandwidth, Archan Misra, Teunis Ott
Research Collection School Of Computing and Information Systems
The introduction of service differentiation in the Internet implies that the residual bandwidth available to best-effort traffic becomes highly variable. We explore the design of a rapidly-reactive congestion control framework, where the ECN-aware best-effort flows aggressively go after any unused capacity. By making routers mark packets in a much more aggressive manner, we are able to achieve fast backoff in the network without resorting to the TCP's current drastic step of halving the congestion window. Simulations indicate that our ECN-mod protocol is better than ECN-NewReno in exploiting rapid variations in the available bandwidth. Moreover, the milder backoff policy of ECN-mod …

Overhauling The Wto: Opportunity At Doha And Beyond, John Audley, Ann Florini
Research Collection School of Social Sciences
The world's trade ministers, who will meet at a WTOministerial in November 2001 in Doha, Qatar, are wrong to think that only a newround of negotiations will save the much-maligned international trade system.Carnegie senior associates John Audley and Ann M. Florini argue that theyshould, instead, simultaneously tackle internal and external reform of the WTOto make it a truly equitable institution. Internally, industrial countries muststart treating developing countries as equal partners in making the rules thatgovern global trade, and where necessary provide technical assistance to makethat equality possible. Externally, to satisfy legitimate public demands,members should improve the transparency of WTO proceedings …

Integrating Color And Spatial Features For Content-Based Video Retrieval, Tong Lin, Chong-Wah Ngo, Hong-Jiang Zhang, Qing-Yun Shi
Research Collection School Of Computing and Information Systems
In this paper, we present a novel and efficient scheme for extracting, indexing and retrieving color images. Our motivation was to reduce the space overhead of partition-based approaches taking advantage of the fact that only a relatively low number of distinct values of a particular visual feature is present in most images. To extract color feature and build indices into our image database we take into consideration factors such as human color perception and perceptual range, and the image is partitioned into a set of regions by using a simple classifying scheme. The compact color feature vector and the spatial …

Mining Multi-Level Rules With Recurrent Items Using Fp'-Tree, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim
Research Collection School Of Computing and Information Systems
Association rule mining has received broad research in the academic and wide application in the real world. As a result, many variations exist and one such variant is the mining of multi-level rules. The mining of multi-level rules has proved to be useful in discovering important knowledge that conventional algorithms such as Apriori, SETM, DIC etc., miss. However, existing techniques for mining multi-level rules have failed to take into account the recurrence relationship that can occur in a transaction during the translation of an atomic item to a higher level representation. As a result, rules containing recurrent items go unnoticed. …
Hierarchical Mobility Management For Voip Traffic, Archan Misra, Subir Das, Anthony J. Mcauley
Hierarchical Mobility Management For Voip Traffic, Archan Misra, Subir Das, Anthony J. Mcauley
Research Collection School Of Computing and Information Systems
A hierarchical IP-based mobility management mechanism is proposed for VoIP applications. The suggested mechanism uses the DMA (dynamic mobility agent) architecture, based on IDMP (intra-domain mobility management protocol), for managing intra-domain mobility and the dynamic binding mechanism of SIP (session initiation protocol) for managing global mobility. This combination of network and application layer mobility management reduces the global signaling load, provides fast handoff for ongoing conversations, enables efficient global transport and supports IP-layer paging.

Consumer Decision Making In A Multi-Generational Choice Set Context, Namwoon Kim, Rajendra K. Srivastava, Jin K. Han
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 …
Nonparametric Techniques To Extract Fuzzy Rules For Breast Cancer Diagnosis Problem, Manish Sarkar, Tze-Yun Leong
Nonparametric Techniques To Extract Fuzzy Rules For Breast Cancer Diagnosis Problem, Manish Sarkar, Tze-Yun Leong
Research Collection School Of Computing and Information Systems
This paper addresses breast cancer diagnosis problem as a pattern classification problem. Specifically, the problem is studied using Wisconsin-Madison breast cancer data set. Fuzzy rules are generated from the input-output relationship so that the diagnosis becomes easier and transparent for both patients and physicians. For each class, at least one training pattern is chosen as the prototype, provided (a) the maximum membership of the training pattern is in the given class, and (b) among all the training patterns, the neighborhood of this training pattern has the least fuzzy-rough uncertainty in the given class. Using the fuzzy-rough uncertainty, a cluster is …

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 …
The Construct Validity Of A Belgian Assessment Centre: A Comparison Of Different Models, Filip Lievens, Etienne Van Keer
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 …
Exploiting Image Indexing Techniques In Dct Domain, Chong-Wah Ngo, Ting-Chuen Pong, Ronald T. Chin
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
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 …

Research Collection School Of Computing and Information Systems
With the rapid growth of information on the Web, a means to combat information overload is critical. In this paper, we present ViDE (Visual Data Extraction), an interactive web data extraction environment that supports efficient hierarchical data wrapping of multiple web pages. ViDE has two unique features that differentiate it from other extraction mechanisms. First, data extraction rules can be easily specified in a graphical user interface that is seamlessly integrated with a web browser. Second, ViDE introduces the concept of grouping which unites the extraction rules for a set of documents with the navigational patterns that exist among them. …

The Determination Of Natural Frequencies Of Rectangular Plates With Mixed Boundary Conditions By Discrete Singular Convolution, G. W. Wei, Yibao Zhao, Y. Xiang
Research Collection Lee Kong Chian School Of Business
This paper introduces the discrete singular convolution algorithm for vibration analysis of rectangular plates with mixed boundary conditions. A unified scheme is proposed for the treatment of simply supported, clamped and transversely supported (with nonuniform elastic rotational restraint) boundary conditions. The robustness and reliability of the present approach are tested by a number of numerical experiments. All results agree well with those in the literature.
