Tourism, Development And Poverty Reduction In Guizhou And Yunnan, John A. Donaldson Jun 2007

Tourism, Development And Poverty Reduction In Guizhou And Yunnan, John A. Donaldson

Research Collection School of Social Sciences

How did the differing strategies adopted to develop tourism in Guizhou and Yunnan affect patterns of economic development and poverty reduction? The answer is paradoxical. Both provincial governments incorporated tourism as part of their overall development strategies, but their tourism sites were distributed and structured strikingly differently. In Yunnan, although tourism contributed to rapid economic growth, it did not reduce rural poverty as much as might be expected from a large rural-based industry. By contrast, Guizhou's relatively small-scale tourism industry, although not contributing significantly to growth, was distributed largely in poor areas and was structured to allow poor people to …


Riau Vegetables For Singapore Consumers: A Collaborative Knowledge-Transfer Project Across The Straits Of Malacca, Thomas Menkhoff, Patrick H. M. Loh, Sin Bin Chua, Hans-Dieter Evers Jun 2007

Riau Vegetables For Singapore Consumers: A Collaborative Knowledge-Transfer Project Across The Straits Of Malacca, Thomas Menkhoff, Patrick H. M. Loh, Sin Bin Chua, Hans-Dieter Evers

Research Collection Lee Kong Chian School Of Business

The paper analyses a recent collaborative knowledge transfer project between the Republic of Singapore and the Republic of Indonesia across the Straits of Malacca. The initiative was aimed at supplying the city state at the southern tip of the Malay Peninsula with green vegetables from Riau, Indonesia, and to provide technical assistance to Riau farmers on protected cultivation and post-harvest technologies. We reconstruct the bilateral evolution of the vegetable project in the context of the long-standing relationships between both countries vis-à-vis Singapore’s reliance on food imports; identify the strategic partner organizations on both sides and their motivations to engage in …


Researching Situated Learning: Participation, Identity And Practices In Client-Consultant Relationships, Karen Handley, Timothy Adrian Robert Clark, Robin Fincham, Andrew Sturdy Jun 2007

Researching Situated Learning: Participation, Identity And Practices In Client-Consultant Relationships, Karen Handley, Timothy Adrian Robert Clark, Robin Fincham, Andrew Sturdy

Research Collection Lee Kong Chian School Of Business

Situated learning theory has emerged as a radical alternative to conventional cognitivist theories of knowledge and learning, emphasizing the relational and structural aspects of learning as well as the dynamics of identity construction. However, although many researchers have embraced the theoretical strengths of this perspective, methodological and operational issues remain undeveloped in the literature. This article seeks to address these deficiencies by developing a conceptual framework informed by situated learning theory and by investigating the methodological implications. The framework is applied in the context of an empirical study of how management consultants learn the practices and identities appropriate to clientconsultant …


A Structuralist Model Of The Small Open Economy In The Short, Medium And Long Run, Hian Teck Hoon, Edmund S. Phelps Jun 2007

A Structuralist Model Of The Small Open Economy In The Short, Medium And Long Run, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

Open-economy macroeconomics contains a monetary model in the Keynesian tradition that is deemed serviceable for analyzing the short run and a nonmonetary neoclassical model thought capable of handling the long run. But do the Keynesian and neoclassical models meet the challenges thrown out by the main events of the past few decades—the ’80s shock to Europe from the sharp increase of external real interest rates; the kind of speculative shock experienced in the U.S. and parts of northern Europe in the second half of the ’90s: the prospect of new industries emerging in the future with needs for new capital; …


Characterizing Exchange Rate Policy In East Asia: A Reconsideration, Hwee Kwan Chow, Yoonbai Kim, Wei Sun Jun 2007

Characterizing Exchange Rate Policy In East Asia: A Reconsideration, Hwee Kwan Chow, Yoonbai Kim, Wei Sun

Research Collection School Of Economics

Frankel and Wei (1994) developed and popularized a method for uncovering the implicit weights assigned to major international currencies constituting a currency basket. We extend the methodology in two dimensions: include regional competitive pressure and employ a vector autoregressive (VAR) model to overcome simultaneity bias. With these modifications, we confirm the prominent role of the US dollar in the exchange rate policy of East Asian economies beyond the short run. However, despite the high degree of commitment to nominal exchange rate stability prior to the crisis, fluctuations in most East Asian currencies are also significantly influenced by country specific shocks. …


A Structuralist Model Of The Small Open Economy In The Short, Medium And Long Run, Hian Teck Hoon, Edmund S. Phelps Jun 2007

A Structuralist Model Of The Small Open Economy In The Short, Medium And Long Run, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

Open-economy macroeconomics contains a monetary model in the Keynesian tradition that is deemed serviceable for analyzing the short run and a nonmonetary neoclassical model thought capable of handling the long run. But do the Keynesian and neoclassical models meet the challenges thrown out by the main events of the past few decades? We first indicate that the effects of these shocks on the open economy are not well captured by either the standard Keynesian model or the standard neoclassical theory. Next we provide a careful development of a nonmonetary model of the equilibrium path of the real exchange rate, share …


Nonlinear Filters Based On Taylor Series Expansions, Hisashi Tanizaki, Roberto S. Mariano Jun 2007

Nonlinear Filters Based On Taylor Series Expansions, Hisashi Tanizaki, Roberto S. Mariano

Research Collection School Of Economics

The nonlinear filters based on Taylor series approximation are broadly used for computational simplicity, even though their filtering estimates are clearly biased. In this paper, first, we analyze what is approximated when we apply the expanded nonlinear functions to the standard linear recursive Kalman filter algorithm. Next, since the state variable αt and αt-t are approximated as a conditional normal distribution given information up to time t - 1 (i.e., It-1) in approximation of the Taylor series expansion, it might be appropriate to evaluate each expectation by generating normal random numbers of αt and α …

Continuous Nearest Neighbor Queries Over Sliding Windows, Kyriakos Mouratidis, Dimitris Papadias Jun 2007

Continuous Nearest Neighbor Queries Over Sliding Windows, Kyriakos Mouratidis, Dimitris Papadias

Research Collection School Of Computing and Information Systems

Recent research has focused on continuous monitoring of nearest neighbors (NN) in highly dynamic scenarios, where the queries and the data objects move frequently and arbitrarily. All existing methods, however, assume the Euclidean distance metric. In this paper we study k-NN monitoring in road networks, where the distance between a query and a data object is determined by the length of the shortest path connecting them. We propose two methods that can handle arbitrary object and query moving patterns, as well as fluctuations of edge weights. The first one maintains the query results by processing only updates that may invalidate …


Simplifying Cyber Foraging For Mobile Devices, Rajesh Krishna Balan, Darren Gergle, Mahadev Satyanarayanan, James Herbsleb Jun 2007

Simplifying Cyber Foraging For Mobile Devices, Rajesh Krishna Balan, Darren Gergle, Mahadev Satyanarayanan, James Herbsleb

Research Collection School Of Computing and Information Systems

Cyber foraging is the transient and opportunistic use of compute servers by mobile devices. The short market life of such devices makes rapid modification of applications for remote execution an important problem. We describe a solution that combines a "little language" for cyber foraging with an adaptive runtime system. We report results from a user study showing that even novice developers are able to successfully modify large, unfamiliar applications in just a few hours. We also show that the quality of novice-modified and expert-modified applications are comparable in most cases.


Maximizing Broadcast And Multicast Traffic Load Through Link-Rate Diversity In Wireless Mesh Networks, Chun Tung Chou, Bao Hua Liu, Archan Misra Jun 2007

Maximizing Broadcast And Multicast Traffic Load Through Link-Rate Diversity In Wireless Mesh Networks, Chun Tung Chou, Bao Hua Liu, Archan Misra

Research Collection School Of Computing and Information Systems

This paper studies some of the fundamental challenges and opportunities associated with the network-layer broadcast and multicast in a multihop multirate wireless mesh network (WMN). In particular, we focus on exploiting the ability of nodes to perform link-layer broadcasts at different rates (with correspondingly different coverage areas). We first show how, in the broadcast wireless medium, the available capacity at a mesh node for a multicast transmission is not just a function of the aggregate pre-existing traffic load of other interfering nodes, but intricately coupled to the actual (sender, receiver) set and the link-layer rate of each individual transmission. We …


Misunderstanding Corruption And Community: Comparative Politics Of Corruption Regulation In The Pacific, Mark Findlay Jun 2007

Misunderstanding Corruption And Community: Comparative Politics Of Corruption Regulation In The Pacific, Mark Findlay

Research Collection Yong Pung How School Of Law

This paper will take as its empirical foundation the author’s experience of corruption and regulation in small Pacific island states. The argument is that notions of corruption and strategies for its regulation suitable for modernized societies, which lack cultural specificity and community engagement, may in fact stimulate corruption relationships in transitional cultures. The other consequence of the imposition of inappropriate definitions and regulation strategies is a profound misunderstanding of communities of dependence. In fact, corruption control can misconstrue and exacerbate economic and political dependence environments, fostering the conditions for corruption which accompany socio-economic development. Two remedies are suggested. First, corruption …

This paper describes a meta-model for innovation using an automobile engine as a metaphor. This innovation meta-model is used to manage a collection of innovation models. We develop an algorithm to identify innovations with potential for success using this meta-model. This meta-model can be used by corporations and individuals to identify plausible innovations at any given point in time.


Zhong Hui (Chung Hui, 225–264 C.E.) In Internet Encyclopedia Of Philosophy, Alan Kam Leung Chan Jun 2007

Zhong Hui (Chung Hui, 225–264 C.E.) In Internet Encyclopedia Of Philosophy, Alan Kam Leung Chan

Research Collection College of Integrative Studies

Zhong Hui (Chung Hui) was a major philosophical figure during China’s early medieval period (220-589 CE). An accomplished interpreter of the Laozi and the Yijing, Zhong Hui contributed significantly to the early development of xuanxue—literally “learning” (xue) of the “dark” or “mysterious” (xuan) Dao (“Way”), but sometimes translated as “Neo-Daoism“. He also was a major political figure whose ambition eventually led to his untimely demise. Virtually all of Zhong Hui’s writings have been lost, which perhaps explains why he has been given scant attention by students of Chinese philosophy. Had he not failed in his attempt to overthrow the regime …


Can Uml Be Simplified? Practitioner Use Of Uml In Separate Domains, J. Erickson, Keng Siau Jun 2007

Can Uml Be Simplified? Practitioner Use Of Uml In Separate Domains, J. Erickson, Keng Siau

Research Collection School Of Computing and Information Systems

UML’s complexity is regularly criticized by practitioners and researchers alike, who argue that such complexity is a considerable detriment to the adoption and use of UML in the field. Attempts have been made to assess and/or measure UML’s complexity in a number of ways. Erickson and Siau proposed that a subset (kernel) of UML, composed of the most important constructs, could be equated with the complexity that practitioners face when using the modeling language. This research extends Erickson and Siau’s work by proposing a UML kernel in three application areas, real-time, webbased and enterprise systems. Compared to other modeling methods …


Intelligence Through Interaction: Towards A Unified Theory For Learning, Ah-Hwee Tan, Gail A. Carpenter, Stephen Grossberg Jun 2007

Intelligence Through Interaction: Towards A Unified Theory For Learning, Ah-Hwee Tan, Gail A. Carpenter, Stephen Grossberg

Research Collection School Of Computing and Information Systems

Machine learning, a cornerstone of intelligent systems, has typically been studied in the context of specific tasks, including clustering (unsupervised learning), classification (supervised learning), and control (reinforcement learning). This paper presents a learning architecture within which a universal adaptation mechanism unifies a rich set of traditionally distinct learning paradigms, including learning by matching, learning by association, learning by instruction, and learning by reinforcement. In accordance with the notion of embodied intelligence, such a learning theory provides a computational account of how an autonomous agent may acquire the knowledge of its environment in a real-time, incremental, and continuous manner. Through a …


The Multi-Agent Data Collection In Hla-Based Simulation System, Heng-Jie Song, Zhi-Qi Shen, Chunyan Miao, Ah-Hwee Tan, Guo-Peng Zhao Jun 2007

The Multi-Agent Data Collection In Hla-Based Simulation System, Heng-Jie Song, Zhi-Qi Shen, Chunyan Miao, Ah-Hwee Tan, Guo-Peng Zhao

Research Collection School Of Computing and Information Systems

The High Level Architecture (HLA) for distributed simulation was proposed by the Defense Modeling and Simulation Office of the Department of Defense (DOD) in order to support interoperability among simulations as well as reuse of simulation models. One aspect of reusability is to collect and analyze data generated in simulation exercises, including a record of events that occur during the execution, and the states of simulation objects. In order to improve the performance of existing data collection mechanisms in the HLA simulation system, the paper proposes a multi-agent data collection system. The proposed approach adopts the hierarchical data management/organization mechanism …


A Hybrid Of Plot-Based And Character-Based Interactive Storytelling, Yundong Cai, Chunyan Miao, Ah-Hwee Tan, Zhiqi Shen Jun 2007

A Hybrid Of Plot-Based And Character-Based Interactive Storytelling, Yundong Cai, Chunyan Miao, Ah-Hwee Tan, Zhiqi Shen

Research Collection School Of Computing and Information Systems

Interactive storytelling in the virtual environment attracts a lot of research interests in recent years. Story plot and character are two most important elements of a story. Based on these two elements, currently there are two research directions: plot-based and character-based interactive storytelling. However, plot-based approach lacks the refinement of character behaviors as character-based approach. On the other side, character-based approach does not follow a well organized story plot so that the moral of the story might be distorted. Therefore, there is a need to develop an integrated framework to achieve the balance between conveying story moral and enhancing the …


An Efficient Identity-Based Key Exchange Protocol With Kgs Forward Secrecy For Low-Power Devices, Robert W. Zhu, Guomin Yang, Duncan S. Wong Jun 2007

An Efficient Identity-Based Key Exchange Protocol With Kgs Forward Secrecy For Low-Power Devices, Robert W. Zhu, Guomin Yang, Duncan S. Wong

Research Collection School Of Computing and Information Systems

For an ID-based key exchange (KE) protocol, KGS forward secrecy is about the protection of previously established session keys after the master secret key of the Key Generation Server (KGS) is compromised. This is the strongest notion of forward secrecy that one can provide for an ID-based KE protocol. Among all the comparable protocols, there are only a few of them that provide this level of forward secrecy, and all of these protocols require expensive bilinear pairing operations and map-to-point hash operations that may not be suitable for implementation on low-power devices such as sensors. In this paper, we propose …


Time Capsule Signature: Efficient And Provably Secure Constructions, Bessie C. Hu, Duncan S. Wong, Qiong Huang, Guomin Yang, Xiaotie Deng Jun 2007

Time Capsule Signature: Efficient And Provably Secure Constructions, Bessie C. Hu, Duncan S. Wong, Qiong Huang, Guomin Yang, Xiaotie Deng

Research Collection School Of Computing and Information Systems

Time Capsule Signature, first formalized by Dodis and Yum in Financial Cryptography 2005, is a digital signature scheme which allows a signature to bear a (future) time t so that the signature will only be valid at time t or later, when a trusted third party called time server releases time-dependent information for checking the validity of a time capsule signature. Also, the actual signer of a time capsule signature has the privilege to make the signature valid before time t.In this paper, we provide a new security model of time capsule signature such that time server is not required …


A More Natural Way To Construct Identity-Based Identification Schemes, Guomin Yang, Jing Chen, Duncan S. Wong, Xiaotie Deng, Dongsheng Wang Jun 2007

A More Natural Way To Construct Identity-Based Identification Schemes, Guomin Yang, Jing Chen, Duncan S. Wong, Xiaotie Deng, Dongsheng Wang

Research Collection School Of Computing and Information Systems

Constructing identification schemes is one of the fundamental problems in cryptography, and is very useful in practice. An identity-based identification (IBI) scheme allows a prover to identify itself to a public verifier who knows only the claimed identity of the prover and some common information. In this paper, we propose a simple and efficient framework for constructing IBI schemes. Unlike some related framework which constructs IBI schemes from some standard identification schemes, our framework is based on some more fundamental assumptions on intractable problems. Depending on the features of the underlying intractable problems presumed in our framework, we can derive …

A Time-And-Value Centric Provenance Model And Architecture For Medical Event Streams, Marion Bllount, John Davis, Archan Misra, Daby Sow, Min Wang Jun 2007

A Time-And-Value Centric Provenance Model And Architecture For Medical Event Streams, Marion Bllount, John Davis, Archan Misra, Daby Sow, Min Wang

Research Collection School Of Computing and Information Systems

Provenance becomes a critical requirement for healthcare IT infrastructures, especially when pervasive biomedical sensors act as a source of raw medical streams for large-scale, automated clinical decision support systems. Medical and legal requirements will make it obligatory for such systems to answer queries regarding the underlying data samples from which output alerts are derived, the IDs of the processing components used and the privileges of the individuals and software components accessing the medical data. Unfortunately, existing models of either annotation or process based provenance are designed for transaction-oriented systems and do not satisfy the unique requirements for systems processing high-volume, …

Learning Nonparametric Kernel Matrices From Pairwise Constraints, Steven C. H. Hoi, Rong Jin, Michael R. Lyu Jun 2007

Learning Nonparametric Kernel Matrices From Pairwise Constraints, Steven C. H. Hoi, Rong Jin, Michael R. Lyu

Research Collection School Of Computing and Information Systems

Many kernel learning methods have to assume parametric forms for the target kernel functions, which significantly limits the capability of kernels in fitting diverse patterns. Some kernel learning methods assume the target kernel matrix to be a linear combination of parametric kernel matrices. This assumption again importantly limits the flexibility of the target kernel matrices. The key challenge with nonparametric kernel learning arises from the difficulty in linking the nonparametric kernels to the input patterns. In this paper, we resolve this problem by introducing the graph Laplacian of the observed data as a regularizer when optimizing the kernel matrix with …
