Rearrangement Of The Bcl-6 Gene As A Prognostic Marker In Diffuse Large-Cell Lymphoma, K. Offit, D.C. Louie, N. Z. Parsa, Denis H. Y. Leung, C. Portlock, B.H. Ye, F. Lista, D.A. Filippa, A. Rosenbaum, M. Ladanyi, S. Jhanwar, R. Dalla-Favera, R.S.K. Changanti

Current therapy can induce a long-term remission in half the patients with diffuse lymphomas with a large-cell component (DLLC), but more intensive treatment has the potential to improve outcome. Rearrangement of a novel candidate proto-oncogene, bcl-6, correlates with a favorable clinical outcome in DLLC and may thus serve as a prognostic marker.
Fallibility And Sequential Decision-Making, Winston T. H. Koh
Fallibility And Sequential Decision-Making, Winston T. H. Koh
Research Collection School Of Economics
Individuals typically make errors in evaluating information. In this paper, we consider a project selection problem, where fallible managers screen projects sequentially, and provide independent opinions on its quality. We compare the relative performance of the hierarchy and polyarchy when η (n > 2) managers are employed to evaluate projects. In addition to generalizing the existing results on the optimal screening standards, I discuss and characterize the optimal organizational size, and how the relative desirability of the two sequential decision processes are affected by changing the project quality. Finally, I also discuss the effect of variable evaluation costs on the optimal …
Policies To Promote Shipping Registration In Singapore, Sock Yong Phang, Rex S. Toh
Policies To Promote Shipping Registration In Singapore, Sock Yong Phang, Rex S. Toh
Research Collection School Of Economics
An analysis traces the development of ship registration in Singapore and examines the underlying motivation behind changes in policies over the last 3 decades. For the better part of the 1970s Singapore was classified as a flag of convenience (FOC) country as it pursued an FOC policy that emphasized the quantitative growth of its merchant fleet. Beginning in 1979 Singapore tightened maritime standards as well as ownership disclosure rules, requiring a foreign shipowner to incorporate a company in Singapore. It is regarded today as a quasi-FOC country - a term associated favorably with countries offering tax incentives to shipowners. The …
Prediction, Filtering, And Smoothing In Nonlinear And Nonnormal Cases Using Monte-Carlo Integration, Hisashi Tanizaki, Roberto S. Mariano
Prediction, Filtering, And Smoothing In Nonlinear And Nonnormal Cases Using Monte-Carlo Integration, Hisashi Tanizaki, Roberto S. Mariano
Research Collection School Of Economics
A simulation-based non-linear filter is developed for prediction and smoothing in non-linear and/or nonnormal structural time-series models. Recursive algorithms of weighting functions are derived by applying Monte Carlo integration. Through Monte Carlo experiments, it is shown that (1) for a small number of random draws (or nodes) our simulation-based density estimator using Monte Carlo integration (SDE) performs better than Kitagawa's numerical integration procedure (KNI), and (2) SDE and KNI give less biased parameter estimates than the extended Kalman filter (EKF). Finally, an estimation of per capita final consumption data is taken as an application to the non-linear filtering problem.
The Vehicle Quota System In Singapore: An Assessment, Winston T. H. Koh, David K. C. Lee
The Vehicle Quota System In Singapore: An Assessment, Winston T. H. Koh, David K. C. Lee
Research Collection Lee Kong Chian School Of Business
This paper reviews the developments since the vehicle quota system was introduced in Singapore in May 1990. We discuss the bidding strategies for the certificates of entitlement (COE) under both the transferable and nontransferable auctions, as well as the equity of the present system and the desirability of transferable COEs. We argue that the COE auction should be made discriminatory and propose an alternative system of COE auction that we feel is both equitable and at the same time politically acceptable. We also survey developments in market competition in the car industry.
The Unctad Liner Code: A Dead Letter?, Sock-Yong Phang, Rex S. Toh
The Unctad Liner Code: A Dead Letter?, Sock-Yong Phang, Rex S. Toh
Research Collection School Of Economics
The UNCTAD Code of conduct for Liner Conferences entered into force in 1983. The Code's cargo allocation scheme or '40-40-20 rule' aims to provide shipping lines of developing countries with a fair change to compete for the carriage of their seabourne trade. However, the Code has not been effective in meeting its stated objectives for a variety of reasons. Amongst the administrative difficulties are (i) the complications introduced by the EEC's Brussels Package, (ii) the definition of national lines, (iii) the unit of measurement for cargo allocation purposes, and (iv) the monitoring of cargo movements. The tremendous growth in non-conference …
International Trade And The Equilibrium Rate Of Unemployment In A Heckscher-Ohlin World Economy, Hian Teck Hoon
International Trade And The Equilibrium Rate Of Unemployment In A Heckscher-Ohlin World Economy, Hian Teck Hoon
Research Collection School Of Economics
This paper develops a (stylized Asia-America) Heckscher-Ohlin world economy in which the equilibrium rate of unemployment is endogenous. We examine the impact of various economic shocks on unemployment in the global economy. Harrod-neutral or Hicks-neutral technical progress across all industries in Asia leads to a terms of trade improvement for America but raises America's unemployment rate. Introducing a third country such as the block of former socialist economies results in higher unemployment for both Asia and America. Protection in America lowers American equilibrium unemployment but raises Asia's unemployment.
