Mediating In The Shadow Of Australian Law: Structural Influences On Adr, Nadja Alexander Jan 2006

Mediating In The Shadow Of Australian Law: Structural Influences On Adr, Nadja Alexander

Research Collection Yong Pung How School Of Law

Mediation has grown rapidly in many Anglophone jurisdictions such as USA, Australia, Canada, New Zealand and England. The current state of mediation practice in many of these jurisdictions can be traced back to the establishment of community justice centres in the 1970s and 1980s. Mediation is practised in the private sector as well as in a wide range of court-referred programs. In many common law jurisdictions mediation is no longer a form of alternative dispute resolution, it has become primary dispute resolution.

Numerus Clausus: An Economic Perspective, Wei Zhang Jan 2006

Numerus Clausus: An Economic Perspective, Wei Zhang

Research Collection Yong Pung How School Of Law

Numerus clausus refers to the principle that both the form and the substance of a property right shall be prescribed by the law, which essentially restricts the freedom to “customize” the legally enforceable property interests.2 It has long been regarded as a basic principle in Civil Law countries, while the recent studies of U.S. scholars suggest that its essence exists in the Anglo-American law as well.

Latin America Bets On Chinese Lessons, Knowledge@Smu Dec 2005

Latin America Bets On Chinese Lessons, Knowledge@Smu

Knowledge@SMU

These days, all roads in international trade seem to lead to China, even in the case of a small country like Chile, which recently signed a free-trade agreement with the Asian giant. It was China’s first free trade treaty with a Western country, and it opens new international routes for its products. In addition, Chinese authorities say the agreement will make Chile a bridge for investments from China into the rest of Latin America. This much is certain: Both China and the dynamic Southeast Asia region are the focal point for Latin American exports. However, the road to Asia is …

Retest Effects In Operational Selection Settings: Development And Test Of A Framework, Filip Lievens, Tine Buyse, Paul R. Sackett Dec 2005

Retest Effects In Operational Selection Settings: Development And Test Of A Framework, Filip Lievens, Tine Buyse, Paul R. Sackett

Research Collection Lee Kong Chian School Of Business

This study proposes a framework for examining the effects of retaking tests in operational selection settings. A central feature of this framework is the distinction between within-person and between-person retest effects. This framework is used to develop hypotheses about retest effects for exemplars of 3 types of tests (knowledge tests, cognitive ability tests, and situational judgment tests) and to test these hypotheses in a high stakes selection setting (admission to medical studies in Belgium). Analyses of within-person retest effects showed that mean scores of repeat test takers were one-third of a standard deviation higher for the knowledge test and situational …

E-Government Capabilities And Crisis Management: Lessons From Combating Sars In Singapore, Shan Ling Pan, Gary Pan, Paul R. Devadoss Dec 2005

E-Government Capabilities And Crisis Management: Lessons From Combating Sars In Singapore, Shan Ling Pan, Gary Pan, Paul R. Devadoss

Research Collection School Of Accountancy

The city-state of Singapore has been highly ranked for its e-government services. Over the past two decades, it has leveraged its IT infrastructure for economic development and transformed its public services. The SARS outbreak in 2004 turned into a national health crisis because it spread rapidly and the medical community had little knowledge of how to treat the new mutation of the corona virus. Yet, several Singaporean government agencies utilized the e-Government infrastructure and related resources to quickly bring the outbreak under control. In particular, the government?s IT infrastructure streamlined communications, information exchange, and data flow, and significantly eased collaboration …

Tailored Watermarking Schemes For Authentication Of Electronic Clinical Atlases, Feng Bao, Robert H. Deng, Beng-Chin Ooi, Yanjiang Yang Dec 2005

Tailored Watermarking Schemes For Authentication Of Electronic Clinical Atlases, Feng Bao, Robert H. Deng, Beng-Chin Ooi, Yanjiang Yang

Research Collection School Of Computing and Information Systems

It is accepted that digital watermarking is quite relevant in medical imaging. However, due to the special nature of clinical practice, it is often required that watermarking not introduce irreversible distortions to medical images. The electronic clinical atlas has such a need of "lossless" watermarking. We present two tailored reversible watermarking schemes for the clinical atlas by exploiting its inherent characteristics. We have implemented the schemes and our experimental results look very promising.

Giving Users The Steering Wheel For Guiding Resource-Adaptive Systems, Joao Sousa, Rajesh Krishna Balan, Vahe Poladian, David Garlan, Mahadev Satyanarayanan Dec 2005

Giving Users The Steering Wheel For Guiding Resource-Adaptive Systems, Joao Sousa, Rajesh Krishna Balan, Vahe Poladian, David Garlan, Mahadev Satyanarayanan

Research Collection School Of Computing and Information Systems

Addressing resource variation plays an increasingly important role in engineering today's software systems. Research in resource-adaptive applications takes an important step towards addressing this problem. However, existing solutions stop short of addressing the fact that different user tasks often have specific goals of quality of service, and that such goals often entail multiple aspects of quality of service. This paper presents a framework for engineering software systems capable of adapting to resource variations in ways that are specific to the quality goals of each user task. For that, users are empowered to specify their task-specific preferences with respect to multiple …

Improving The Quality Of Conceptual Modeling Using Cognitive Mapping Techniques, Keng Siau, X. Tan Dec 2005

Improving The Quality Of Conceptual Modeling Using Cognitive Mapping Techniques, Keng Siau, X. Tan

Research Collection School Of Computing and Information Systems

Conceptual modeling involves the understanding and communication between system analysts and end-users. Many factors may affect the quality of conceptual modeling processes as well as the models per se. Human cognition plays a pivotal role in understanding these factors and cognitive mapping techniques are effective tools to elicit and represent human cognition. In this paper, we look at the use of cognitive mapping techniques to improve the quality of conceptual modeling. We review frameworks on quality in conceptual modeling and examine the role of human cognition in conceptual modeling. The paper also discusses how human cognition is related to quality …

Matrix: Adaptive Middleware For Distributed Multiplayer Games, Rajesh Krishna Balan, Maria Ebling, Paul Castro, Archan Misra Dec 2005

Matrix: Adaptive Middleware For Distributed Multiplayer Games, Rajesh Krishna Balan, Maria Ebling, Paul Castro, Archan Misra

Research Collection School Of Computing and Information Systems

Building a distributed middleware infrastructure that provides the low latency required for massively multiplayer games while still maintaining consistency is non-trivial. Previous attempts have used static partitioning or client-based peer-to-peer techniques that do not scale well to a large number of players, perform poorly under dynamic workloads or hotspots, and impose significant programming burdens on game developers. We show that it is possible to build a scalable distributed system, called Matrix, that is easily usable by game developers. We show experimentally that Matrix provides good performance, especially when hotspots occur.

A Framework To Learn Bayesian Network From Changing, Multiple-Source Biomedical Data, Li G., Tze-Yun Leong Dec 2005

A Framework To Learn Bayesian Network From Changing, Multiple-Source Biomedical Data, Li G., Tze-Yun Leong

Research Collection School Of Computing and Information Systems

Structure learning in Bayesian network is a big issue. Many efforts have tried to solve this problem and quite a few algorithms have been proposed. However, when we attempt to apply the existing methods to microarray data, there are three main challenges: 1) there are many variables in the data set, 2) the sample size is small, and 3) microarray data are changing from experiment to experiment and new data are available quickly. To address these three problems, we assume that the major functions of a kind of cells do not change too much in different experiments, and propose a …

Integration Of Probabilistic Graphic Models For Decision Support, Jiang C., Poh K., Tze-Yun Leong Dec 2005

Integration Of Probabilistic Graphic Models For Decision Support, Jiang C., Poh K., Tze-Yun Leong

Research Collection School Of Computing and Information Systems

It is a frequently encountered problem that new knowledge arrived when making decisions in a dynamic world. Usually, domain experts cannot afford enough time and knowledge to effectively assess and combine both qualitative and quantitative information in these models. Existing approaches can solve only one of two tasks instead of both. We propose a four-step algorithm to integrate multiple probabilistic graphic models, which can effectively update existing models with newly acquired models. In this algorithm, the qualitative part of model integration is performed first, followed by the quantitative combination. We illustrate our method with an example of combining three models. …

The Internet And Civil Society: Environmental And Labour Organizations In Hong Kong, Yin-Wah Chu, James T. H. Tang

Research Collection School of Social Sciences

To what extent has the Internet strengthened civil society? In which ways have civil society organizations (CSOs) used the internet to communicate their missions, enhance the discussion of public issues, extend networks and mobilize collective actions? This article seeks to answer these and related questions by reporting on an empirical study in Hong Kong. The study involves an analysis of the web pages launched by 14 environmental groups and 22 labour organizations on the one hand, and in-depth interviews with representatives of five of these organizations on the other. Due to the lack of resources and low level of e-readiness …

Examining The Relationship Between Employer Knowledge Dimensions And Organizational Attractiveness: An Application In A Military Context, Filip Lievens, Greet Van Hoye, Bert Schreurs Dec 2005

Examining The Relationship Between Employer Knowledge Dimensions And Organizational Attractiveness: An Application In A Military Context, Filip Lievens, Greet Van Hoye, Bert Schreurs

Research Collection Lee Kong Chian School Of Business

This study uses Cable and Turban's (2001) employer knowledge framework as a conceptual model to formulate hypotheses about a broad range of possible factors affecting the attractiveness of an organization (i.e. armed forces) among potential applicants (576 high-school seniors). Results show that gender, familiarity with military organizations, perceptions of job and organizational attributes (task diversity and social/team activities), and trait inferences (excitement, prestige, and cheerfulness) explained potential applicants' attraction to military organizations. Relative importance analyses showed that trait inferences contributed most to the variance, followed by job and organizational attributes, and employer familiarity. Finally, we found some evidence of interactions …

Consumer Preferences For High-Tech Product Forms: Converged Or Separate? Evolution Of Technology & Reversal Of Preferences, Jin K. Han, Seh-Woong Chung, Seok Sohn Yong Dec 2005

Consumer Preferences For High-Tech Product Forms: Converged Or Separate? Evolution Of Technology & Reversal Of Preferences, Jin K. Han, Seh-Woong Chung, Seok Sohn Yong

Research Collection Lee Kong Chian School Of Business

With the surging popularity and growing availability of convergence products (e.g., camera phones, all-in-one PDAs) in high-tech product categories, consumers now face another dilemma in their purchase consideration: which product form converged, stand-alone, or both? This study sets out to investigate pattern(s) of consumer preferences for product form along the evolution of technology trajectories. In two experiments, we find that, at low levels of technological performance, consumers show an overwhelming preference for the converged product form over the dedicated counterpart; whereas, at a higher technological performance level, the pattern of preferences is reversed. Furthermore, we observe that a preannouncement of …

Review Of Unity Of Knowledge And Action: Toward A Nonrepresentational Theory Of Knowledge, Sor-Hoon Tan Dec 2005

Review Of Unity Of Knowledge And Action: Toward A Nonrepresentational Theory Of Knowledge, Sor-Hoon Tan

Research Collection School of Social Sciences

The title of this book is inspired by the Neo-Confucian scholar, Wang Yangming (1472-1529). However, the volume is not devoted solely to Wang Yangming's philosophy about the unity of knowledge and action. Wang is only one of several thinkers brought into this philosophical conversation and does not even receive the most attention (Richard Rorty has that honor). The conver- sation is interesting and occasionally illuminating, although one is not sure at the end whether it is moving toward one particular nonrepresentation theory of knowledge or whether the conversation partners who share an aversion to representational theories might disagree profoundly about …

Cultural Crossings Against Ethnocentric Currents: Toward A Confucian Ethics Of Communicative Virtues, Sor-Hoon Tan Dec 2005

Cultural Crossings Against Ethnocentric Currents: Toward A Confucian Ethics Of Communicative Virtues, Sor-Hoon Tan

Research Collection School of Social Sciences

Despite contemporary Confucianism's aspirations to be a world philosophy, there is an ethnocentric strand within the Confucian tradition, most glaringly exemplified in Han Yu's attacks on Buddhism. This paper re-assesses Confucian ethnocentrism in the context of contrary practices that indicate a more pragmatic attitude among Confucians toward cross-cultural interactions. It argues that while the ethnocentric tendency serves as constant reminder of the need for vigilance, and recognition of the difficulties of crossing cultural boundaries, there are nevertheless resources within Confucianism for constructing an ethics of communication that is urgently needed to deal with the moral problems of cultural pluralism. The …

A Generic Object-Oriented Tabu Search Framework, Hoong Chuin Lau, Xiaomin Jia, Wee Chong Wan Dec 2005

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

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 well- designed 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 …

Determinants Of Intra-Day Stock Price Change And Asymmetric Information, Christopher Hian Ann Ting Dec 2005

Determinants Of Intra-Day Stock Price Change And Asymmetric Information, Christopher Hian Ann Ting

Research Collection Lee Kong Chian School Of Business

This paper presents a synthesized model of asymmetric information. An empirical analysis of more than 1,400 NYSE common stocks shows that trade direction is more important than volume in revealing the asymmetry. There is also evidence to suggest that signed duration reflects informed trading activity. We use the proposed measure of information asymmetry to study daily changes in the level of informed trading and find that earnings announcements narrow the information gap between the informed and the uninformed. On average, information asymmetry is largest at the beginning of the trading day and it decreases monotonically toward the closing bell. More …

Fostering Total Wellness Through Peer Helping: Reflections On The Smu Experiences, Gilbert Tan, Timothy Hsi Dec 2005

Fostering Total Wellness Through Peer Helping: Reflections On The Smu Experiences, Gilbert Tan, Timothy Hsi

Research Collection Lee Kong Chian School Of Business

Peer Helping is widely implemented in Colleges and Universities in the United States and Canada. Despite the popularity of these programs, very little has been researched on peer helping in the Asian context. This paper traces the theoretical foundations of peer helping and the nascent development of a peer helping program in the Singapore Management University and how this program has developed since the beginning of 2004. The initial focus of the program was based on the model of paraprofessional student counselors assisting their fellow peers through difficult moments in their lives. Over time, the program was fine-tuned to embrace …

Using Community Service Projects To Teach Leadership And Team-Building: Theoretical Foundations, Students' Reactions And Practical Considerations, Gilbert Tan Dec 2005

Using Community Service Projects To Teach Leadership And Team-Building: Theoretical Foundations, Students' Reactions And Practical Considerations, Gilbert Tan

Research Collection Lee Kong Chian School Of Business

This paper discusses the theoretical foundations of utilizing Community Service Project (CSP) or service-learning to teach Leadership and Team-Building. It examines the students’ reactions to this innovative method of instruction. This is done through conducting a content analysis of students’ learning journals, in which students reflect on their CSP learning experiences. Two themes emerged from the data: (a) variety of learning experiences, and (b) impact of CSP experience. The data suggested that students derived a variety of learning experiences from the CSP. In addition, there were attitudinal and learning impacts associated with the CSP experiences. The paper also outlines some …

Natural Forum And The Elusive Significance Of Jurisdiction Agreements, Tiong Min Yeo Dec 2005

Natural Forum And The Elusive Significance Of Jurisdiction Agreements, Tiong Min Yeo

Research Collection Yong Pung How School Of Law

The Singapore court's power to stay its proceedings by reason of its not being the appropriate forum the proceedings ought not to be continued is underpinned by the common law principle enunciated in The Spiliada that generally a trial should be heard in its natural forum. The Rainbow Joy adds significantly to Singapore law on forum non conveniens on two important points. First, it establishes that it is not necessary to show that the alternative forum abroad is constituted as a court of law. Secondly, the case establishes that whether there is a defense claim on the merits is an …

A Block Oriented Fingerprinting Scheme In Relational Database, Siyuan Liu, Shuhong Wang, Robert H. Deng, Weizhong Shao Dec 2005

A Block Oriented Fingerprinting Scheme In Relational Database, Siyuan Liu, Shuhong Wang, Robert H. Deng, Weizhong Shao

Research Collection School Of Computing and Information Systems

The need for protecting rights over relational data is of ever increasing concern. There have recently been some pioneering works in this area. In this paper, we propose an effective fingerprinting scheme based on the idea of block method in the area of multimedia fingerprinting. The scheme ensures that certain bit positions of the data contain specific values. The bit positions are determined by the keys known only to the owner of the data and different buyers of the database have different bit positions and different specific values for those bit positions. The detection of the fingerprint can be completed …

Cryptanalysis Of A Forward Secure Blind Signature Scheme With Provable Security, Shuhong Wang, Feng Bao, Robert H. Deng Dec 2005

Cryptanalysis Of A Forward Secure Blind Signature Scheme With Provable Security, Shuhong Wang, Feng Bao, Robert H. Deng

Research Collection School Of Computing and Information Systems

A forward secure blind signature scheme was proposed by Duc, Cheon and Kim, in ICICS 2003. The security of the scheme was proved to be equivalent to the strong RSA assumption in the random oracle model. In this paper we present an attack to the scheme by forging valid signatures with public keys only. The attack is so efficient that forging a valid signature needs less computation than legally generating a signature, even considering only the user side. Our result implies that the security proof of the scheme must be invalid. Furthermore we point out the fault of the proof …

Authenticating Query Results In Data Publishing, Di Ma, Robert H. Deng, Hwee Hwa Pang, Jianying Zhou Dec 2005

Authenticating Query Results In Data Publishing, Di Ma, Robert H. Deng, Hwee Hwa Pang, Jianying Zhou

Research Collection School Of Computing and Information Systems

We propose a communication-efficient authentication scheme to authenticate query results disseminated by untrusted data publishing servers. In our scheme, signatures of multiple tuples in the result set are aggregated into one and thus the communication overhead incurred by the signature keeps constant. Next attr-MHTs (tuple based Merkle Hash Tree) are built to further reduce the communication overhead incurred by auxiliary authentication information (AAI). Besides the property of communication-efficiency, our scheme also supports dynamic SET operations (UNION, INTERSECTION) and dynamic JOIN with immunity to reordering attack.

An Efficient And Robust Computational Framework For Studying Lifetime And Information Capacity In Sensor Networks, Enrique J. Duarte-Melo, Mingyan Liu, Archan Misra Dec 2005

An Efficient And Robust Computational Framework For Studying Lifetime And Information Capacity In Sensor Networks, Enrique J. Duarte-Melo, Mingyan Liu, Archan Misra

Research Collection School Of Computing and Information Systems

In this paper we investigate the expected lifetime and information capacity, defined as the maximum amount of data (bits) transferred before the first sensor node death due to energy depletion, of a data-gathering wireless sensor network. We develop a fluid-flow based computational framework that extends the existing approach, which requires precise knowledge of the layout/deployment of the network, i.e., exact sensor positions. Our method, on the other hand, views a specific network deployment as a particular instance (sample path) from an underlying distribution of sensor node layouts and sensor data rates. To compute the expected information capacity under this distribution-based …

Webarc: Website Archival Using A Structured Approach, Ee Peng Lim, Maria Marissa

Research Collection School Of Computing and Information Systems

Website archival refers to the task of monitoring and storing snapshots of website(s) for future retrieval and analysis. This task is particularly important for websites that have content changing over time with older information constantly overwritten by newer one. In this paper, we propose WEBARC as a set of software tools to allow users to construct a logical structure for a website to be archived. Classifiers are trained to. determine relevant web pages and their categories, and subsequently used in website downloading. The archival schedule can be specified and executed by a scheduler. A website viewer is also developed to …

A Grapheme To Phoneme Converter For Standard Malay, Haizhou Li, Mahani Aljunied, Boon Seong Teoh Dec 2005

A Grapheme To Phoneme Converter For Standard Malay, Haizhou Li, Mahani Aljunied, Boon Seong Teoh

Research Collection Lee Kong Chian School Of Business

This paper describes the process of creating a grapheme-to-phoneme (G2P) converter for Standard Malay (SM). A fundamental step to building TTS and ASR engines, is to build a good G2P system that can automatically generate accurate phonemic representations for words. Our goal is to generate phonemes that reflect real speech, thereby facilitating more accurate phoneme alignment with actual waveforms (obtained from voice-data collection), keeping human intervention to the minimum. Here we discuss the key areas in SM that require considerable phonemic alterations including letter elisions, consonant insertions, multiple ways of uttering a letter/diagraph – areas that any good G2P system …

Mri-Assessed Volume Of Left And Right Hippocampi In Females Correlates With The Relative Length Of The Second And Fourth Fingers (The 2d : 4d Ratio), Janos Kallai, Arpad Csatho, Ferenc Kover, Tamas Makany, Janos Nemes, Krisztina Horvath, Norbert Kovacs, John T. Manning, Lynn Nadel, Ferenc Nagy Nov 2005

Mri-Assessed Volume Of Left And Right Hippocampi In Females Correlates With The Relative Length Of The Second And Fourth Fingers (The 2d : 4d Ratio), Janos Kallai, Arpad Csatho, Ferenc Kover, Tamas Makany, Janos Nemes, Krisztina Horvath, Norbert Kovacs, John T. Manning, Lynn Nadel, Ferenc Nagy

Research Collection Lee Kong Chian School Of Business

Atrophy of the left or right side of the hippocampus has been related to cognitive deficits and psychiatric disease. In this study, we examined the correlation between the hippocampal volume laterality index and the relative lengths of the second (index finger) and fourth (ring finger) digits (2D:4D) in healthy female subjects. The 2D:4D ratio is fixed in utero, and the ratio is higher in women than in men. There is evidence that this ratio is an indicator of the intrauterine concentration of testosterone, which influences the development of different regions of the brain. Assessing the volume of different parts of …
