Cosign: A Parallel Algorithm For Coordinated Traffic Signal Control, Shih-Fen Cheng, Marina A. Epelman, Robert L. Smith Dec 2006

Cosign: A Parallel Algorithm For Coordinated Traffic Signal Control, Shih-Fen Cheng, Marina A. Epelman, Robert L. Smith

Research Collection School Of Computing and Information Systems

The problem of finding optimal coordinated signal timing plans for a large number of traffic signals is a challenging problem because of the exponential growth in the number of joint timing plans that need to be explored as the network size grows. In this paper, the game-theoretic paradigm of fictitious play to iteratively search for a coordinated signal timing plan is employed, which improves a system-wide performance criterion for a traffic network. The algorithm is robustly scalable to realistic-size networks modeled with high-fidelity simulations. Results of a case study for the city of Troy, MI, where there are 75 signalized …


Reiterated Commemoration: Hiroshima As National Trauma, Hiro Saito Dec 2006

Reiterated Commemoration: Hiroshima As National Trauma, Hiro Saito

Research Collection School of Social Sciences

This article examines historical transformations of Japanese collective memory of the atomic bombing of Hiroshima by utilizing a theoretical framework that combines a model of reiterated problem solving and a theory of cultural trauma. I illustrate how the event of the nuclear fallout in March 1954 allowed actors to consolidate previously fragmented commemorative practices into a master frame to define the postwar Japanese identity in terms of transnational commemoration of "Hiroshima." I also show that nationalization of trauma of "Hiroshima" involved a shift from pity to sympathy in structures of feeling about the event. This historical study suggests that a …


With The Grain Or Against The Grain? Energy Security And Chinese Foreign Policy In The Hu Jintao Era, James T. H. Tang Oct 2006

With The Grain Or Against The Grain? Energy Security And Chinese Foreign Policy In The Hu Jintao Era, James T. H. Tang

Research Collection School of Social Sciences

Are China’s growing energy needs insatiable, and is a resource war between China and other major energy-consuming countries, such as the United States, inevitable? China’s pursuit of overseas energy resources to feed its fast-growing economy has given rise to observations that energy is now the driving force behind Chinese foreign policy and predictions that potential conflicts between China and other countries are likely to arise as China becomes more aggressive internationally in search of resources.


Knowledges Of The Creative Economy: Towards A Relational Geography Of Diffusion And Adaptation In Asia, Lily Kong, Chris Gibson, Louisa-May Khoo, Anne-Louise Semple Aug 2006

Knowledges Of The Creative Economy: Towards A Relational Geography Of Diffusion And Adaptation In Asia, Lily Kong, Chris Gibson, Louisa-May Khoo, Anne-Louise Semple

Research Collection School of Social Sciences

Recent dialogues in geography and the social sciences have reminded researchers of the extent to which academic and policy knowledges are socially and spatially embedded-that is, they circulate through formal and informal systems of publishing, exchange, commodification and cultural influence. Academic and policy knowledges are, in short, very much a part of the creative economy. In light of this, our paper surveys knowledges of the creative economy itself, as reflected in a geography of industry reports and government policy statements in selected Asian countries. Using a post-positivist framework adapted from diffusion theory, we critically interpret the circulation, mutation and adaptation …


Do We Stand On Common Ground? A Threat Appraisal Model For Terror Alerts Issued By The Department Of Homeland Security, Augustine Pang, Jin Yan, Glen T. Cameron Jun 2006

Do We Stand On Common Ground? A Threat Appraisal Model For Terror Alerts Issued By The Department Of Homeland Security, Augustine Pang, Jin Yan, Glen T. Cameron

Research Collection Lee Kong Chian School Of Business

The fabric and faces of threat, and the expediency and efficiency in the communication of threat, are examined with a threat appraisal model. This model is empirically tested on an ongoing communication challenge, the issuance of terror alerts by the United States' Department of Homeland Security (DHS), focusing on how threat is appraised by both the conservative and liberal audiences. Findings showed a shared view by the DHS and conservative audiences on the levels and nature of threats; liberal audiences thought otherwise. Though there appeared to be a consensus between the conservative and liberal audiences on the efficacy of threat …


The Transition From Relational To Legal Contract Enforcement, Fali Huang Jun 2006

The Transition From Relational To Legal Contract Enforcement, Fali Huang

Research Collection School Of Economics

This paper studies the transition of contract enforcement institutions. The prevalence of relational contracts, low legal quality, strong cultural preference for personalistic relationships, low social mobility, and highly unequal endowment form a cluster of mutually reinforcing institutions that hinder economic development. The cultural element per se does not necessarily reduce social welfare though it may slow down the legal development, while the real problem lies in endowment inequality and low social mobility. Thus a more equal distribution of resources may be the ultimate key to unravel the above interlocking institutions. These results are generally consistent with the empirical evidence.


Religion And Spaces Of Technology: Constructing And Contesting Nation, Transnation, And Place, Lily Kong May 2006

Religion And Spaces Of Technology: Constructing And Contesting Nation, Transnation, And Place, Lily Kong

Research Collection School of Social Sciences

In this paper, I focus on one particular technological development that has come to influence religious practice in significant ways-religious broadcasting. Whereas computer-mediated communications now garner growing research attention, I have chosen to remember the influence of the older technology of broadcasting for its continued influence on myriad lives. In bringing this focus to bear on another major phenomenon, that of trans nationalism, I have come to understand how religious broadcasting does not contribute in a straightforward, linear fashion to perpetuating transnational identities and communities, but is instead implicated in the assertion of the national in the face of transnational …


The Public Policy And Mandatory Rules Of Third Countries In International Contracts, Adeline Chong Apr 2006

The Public Policy And Mandatory Rules Of Third Countries In International Contracts, Adeline Chong

Research Collection Yong Pung How School Of Law

While party autonomy has risen in the field of contract, this autonomy is not unfettered. Parties are allowed to choose the governing law of the contract but limitations on party choice can be seen through the operation of public policy and mandatory rules. The public policy and mandatory rules of three laws may be imposed onto the contract: that of the lex fori, the governing law of the contract and the law of a third country with a connection to the contract. It is generally accepted that the public policy and mandatory rules of the forum have a legitimate role …


How Well Can We Target Resources With Quick-And-Dirty Data?: Empirical Results From Cambodia, Tomoki Fujii Feb 2006

How Well Can We Target Resources With Quick-And-Dirty Data?: Empirical Results From Cambodia, Tomoki Fujii

Research Collection School Of Economics

Proverty reduction is a top priority for international organizations, governments and non-gorvernmental organizations. The aid resources available for poverty reduction are, however, severely constrained in many countries. Minimizing the leakage of aid resources to the non-poor is a key to maximize poverty reduction with the limited amount of resources available. One Way to minimize such leakage to to target resources geographically. That is, policmakers can move resources to the poorest parts of the country. Geographic taregting can quite effective when poverty is unevenly distributed across the country, and this proves to be the case in many countries.

Commune-Level Estimation Of Poverty Measure And Its Application In Cambodia, Tomoki Fujii Jan 2006

Commune-Level Estimation Of Poverty Measure And Its Application In Cambodia, Tomoki Fujii

Research Collection School Of Economics

Cambodia is still suffering from the legacy of civil conflict after more than a decade. With over one-third of the population living below the poverty line, poverty remains one of the most serious problems in Cambodia. A number of governmental bodies, local and international nongovernmental organizations (NGOs), and international organizations operating in Cambodia have made eradicating poverty a priority and have established many social programmes to this end. In designing such programmes, the efficient allocation of resources is essential for making poverty alleviation more cost-effective. Targeting is often helpful for this purpose because one can avoid wasting resources on the …


The Role Of European Governments In The Digital Economy, Arnoud Cyriel Leo De Meyer Jan 2006

The Role Of European Governments In The Digital Economy, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

What is the role of government in the digital economy? It is not our intention to go into an in-depth ideological debate on whether governments should intervene in the business sector. We will try to adopt a pragmatic approach and explore what already happens in practice. It is up to the reader to make a judgment to what extent the governments should be involved in the ICT sector. There is enough indication that, due to network externality effects, governments need to take on an active role in stimulating an e-environment to jump-start the move toward a higher level of e-readiness.In …


A Code Of Conduct For Indonesia: Problems And Perspectives, Riccardo Pelizzo, Bernice Ang Jan 2006

A Code Of Conduct For Indonesia: Problems And Perspectives, Riccardo Pelizzo, Bernice Ang

Research Collection School of Social Sciences

The purpose of the present paper is fairly straightforward. We want to show that institutional reforms, such as the adoption of a conduct code, represent a necessary albeit insufficient condition to curb corruption and promote good governance. As several scholars have pointed out the success of institutional reform in general and the success of codes of conduct in particular depends, among other things, on ideational conditions. With regard to codes of conduct, parliamentary ethics experts believe in fact that the success of a code of conduct depends on whether the individuals who are supposed to be regulated by the disposition …
