A Comparison Of The Perceptions Of Clients And Design Consultants Toward Corporate Identity Programs, Dae Ryun Chang, Don Ryun Chang, Kwon Soo Lee
Research Collection Lee Kong Chian School Of Business
Although much attention has been given to the importance of developing and using corporate and brand identity programs (from hereon essentially combined and referred to as CI), in the business literature in contrast academic treatment is less abundant and in particular there is little research on their actual implementation. While the motivation for the emergence of CI is easily understood, what is not clear is how effective these programs are after implementation. In this paper we focus on two communities responsible for the creation and implementation of identity programs, the clients and the designers. Even within client corporations of CI …

Organization Structure And Structural Change In European Manufacturing Organisations, Derek Pugh, Timothy Adrian Robert Clark, Geoff Mallory
Research Collection Lee Kong Chian School Of Business
The paper considers two approaches to thestudy of the impact of national cultures on thestructure of organizations; viz: culture free andculture bound approaches. Af ter a discussionof the problems of obtaining comparable datain cross-cultural research, the preliminary results of a comparative study of large manufacturing organizations in six countries in Europeare presented. The results suggest that whileformal organizational authority structures appear to be culture free reflecting the impact ofstrategic contingencies, use of coordinationtechniques, such as regular top managementmeetings and task forces, is more affected bycultural factors.

Temporary Equililibrium Dynamics With Learning: The Stability Of Random Walk Beliefs, Shurojit Chatterji
Temporary Equililibrium Dynamics With Learning: The Stability Of Random Walk Beliefs, Shurojit Chatterji
Research Collection School Of Economics
This paper examines the stability of deterministic steady-states with a one dimensional state-variable and a smooth, recursive updating rule. It is shown that the only possibly stable steady states are those associated with random walk beliefs, provided there is motion on a center manifold, which is the case when a key parameter is non-zero; In the extant literature, there is no motion on the center manifold (the parameter is zero), a consequence of the specific assumption that the expected value of the state variable next period determines its current value. The stability properties are seen to be robust with respect …
On The Complexity Of Manpower Shift Scheduling, Hoong Chuin Lau
On The Complexity Of Manpower Shift Scheduling, Hoong Chuin Lau
Research Collection School Of Computing and Information Systems
We consider the shift assignment problem in manpower scheduling, and show that a restricted version of it is NP-hard by a reduction from 3SAT. We then present polynomial algorithms to solve special cases of the problem and show how they can be deployed to solve more complex versions of the shift assignment problem. Our work formally defines the computational intractibility of manpower shift scheduling and thus justifies existing works in developing manpower scheduling systems using combinatorial and heuristic techniques.
Improved Measurement Of The B0 And B+ Meson Lifetimes, D. Buskulic, M. Thulasidas
Improved Measurement Of The B0 And B+ Meson Lifetimes, D. Buskulic, M. Thulasidas
Research Collection School Of Computing and Information Systems
Updated measurements of the B0 and B+ meson lifetimes are presented. From a data sample of 1.72 million hadronic Z0 decays recorded during the period 1991 to 1993, a sample of approximately 1000 semileptonic B meson decays containing a D0, D+ or D*+ has been isolated. From the distribution of decay times in the different samples the lifetimes of the B0 and B+ mesons are determined to be 1.53±0.12±0.08 ps and 1.52±0.14±0.09 ps, respectively, where the first error is statistical and the second systematic. The ratio of the B+ to B0 lifetimes is measured to be 0.99±0.14+0.05−0.04, confirming expectations that …
Making "Music At The Margins"? A Social And Cultural Analysis Of Xinyao In Singapore, Lily Kong
Making "Music At The Margins"? A Social And Cultural Analysis Of Xinyao In Singapore, Lily Kong
Research Collection School of Social Sciences
Formalist critics and aestheticians have argued that music does not possess any kind of "extra-musical" significance, that there is no meaning beyond the form and structural relations of the notes. For them, music exemplifies the laws of mathematical harmony and proportion rather than the social and political contexts within which it is produced, reproduced and consumed. This view has been challenged by a number of social theorists: Max Weber, Theodor Adorno and Edward Said have all argued for an understanding of music within its social, cultural, economic and political contexts. Such analysis of popular music is now unquestioned. Indeed, it …

Determination Of Sin2Θw Eff Using Jet Charge Measurements In Hadronic Z Decays, D. Buskulic, M. Thulasidas
Research Collection School Of Computing and Information Systems
The electroweak mixing angle is determined with high precision from measurements of the mean difference between forward and backward hemisphere charges in hadronic decays of the Z. A data sample of 2.5 million hadronic Z decays recorded over the period 1990 to 1994 in the ALEPH detector at LEP is used. The mean charge separation between event hemispheres containing the original quark and antiquark is measured forbb¯bb¯ andcc¯cc¯ events in subsamples selected by their long lifetimes or using fastD*’s. The corresponding average charge separation for light quarks is measured in an inclusive sample from the anticorrelation between charges of opposite …
Measurement Of The Λb Polarization In Z Decays, Buskulic, D.; Et Al., M. Thulasidas
Measurement Of The Λb Polarization In Z Decays, Buskulic, D.; Et Al., M. Thulasidas
Research Collection School Of Computing and Information Systems
The Λb polarization in hadronic Z decays is measured in semileptonic decays from the average energies of the charged lepton and the neutrino. In a data sample of approximately 3 million hadronic Z decays collected by the ALEPH detector at LEP between 1991 and 1994, 462 ± 31 Λb candidates are selected using (Λπ+)-lepton correlations. From this event sample, the Λb polarization is measured to be PΛb = −0.23−0.20+0.24(stat.)−0.07+0.08(syst.).
Combinatorial Approaches For Hard Problems In Manpower Scheduling, Hoong Chuin Lau
Combinatorial Approaches For Hard Problems In Manpower Scheduling, Hoong Chuin Lau
Research Collection School Of Computing and Information Systems
Manpower scheduling is concerned with the construction of a workers' schedule which meets demands while satisfying given constraints. We consider a manpower scheduling Problem, called the Change Shift Assignment Problem(CSAP). In previous work, we proved that CSAP is NP-hard and presented greedy methods to solve some restricted versions. In this paper, we present combinatorial algorithms to solve more general and realistic versions of CSAP which are unlikely solvable by greedy methods. First, we model CSAP as a fixed-charge network and show that a feasible schedule can be obtained by finding disjoint paths in the network, which can be derived from …
Randomized Approximation Of The Constraint Satisfaction Problem, Hoong Chuin Lau, Osamu Watanabe
Randomized Approximation Of The Constraint Satisfaction Problem, Hoong Chuin Lau, Osamu Watanabe
Research Collection School Of Computing and Information Systems
We consider the Weighted Constraint Satisfaction Problem (W-CSP) which is a fundamental problem in Artificial Intelligence and a generalization of important combinatorial problems such as MAX CUT and MAX SAT. In this paper, we prove non-approximability properties of W-CSP and give improved approximations of W-CSP via randomized rounding of linear programming and semidefinite programming relaxations. Our algorithms are simple to implement and experiments show that they are run-time efficient.

Medical Investigation Of Suspects By The Police, Jack Tsen-Ta Lee
Research Collection Yong Pung How School Of Law
Although medical examinations and samples taken from suspects' bodies in the course of police inquiries often lead to the discovery of important evidence, Singapore criminal procedure does not appear to empower the police to carry out such medical investigations. Neither does it safeguard the interests of suspects. It is submitted that the Criminal Procedure Code and other statutes should be brought up to date with modern science.

Research Collection Yong Pung How School Of Law
This article considers, from the perspectives of legal history and jurisprudence, longstanding controversy surrounding the interpretation of the phrase "wrong or contra to law" in section 84 of the Penal Code, and suggests that the evidence points to interpretation that "wrong" means "legally wrong" or "contrary to law". It also consid the practical implications that follow from such an interpretation, which implicatio would allow for some role, nevertheless, for extral

Temporary Equilibrium Dynamics With Bayesian Learning, Shurojit Chatterji
Temporary Equilibrium Dynamics With Bayesian Learning, Shurojit Chatterji
Research Collection School Of Economics
This paper examines the stability of deterministic steady states in a class of economies where the state variable is one dimensional and where agents use Bayesian techniques to form expectations. The dynamics with learning are locally convergent if the prior mean is close to a stable perfect-foresight root having modulus less than 1 and if the prior beliefs are held with enough confidence. The dynamics are, however, divergent if the prior mean or the variance of the prior distribution is sufficiently large
The Effects Of Conceptual And Logical Interfaces On Visual Query Performance Of End Users, Keng Siau, H. Chan, K. Wei
The Effects Of Conceptual And Logical Interfaces On Visual Query Performance Of End Users, Keng Siau, H. Chan, K. Wei
Research Collection School Of Computing and Information Systems
To the end users, the interface is the system. A better interface not only facilitates end user interaction with the database, it also enables them to formulate queries more efficiently and effectively. Two of the most important user-database interfaces are the conceptual and logical interfaces. With the conceptual interface, the user communicates with tile database system in terms ofentities, objects and relationships. On the other hand, the current user-database interaction is mainly based on the logical interface where the user expresses the queries in terms of relations and join operations. Because the concepts at the logical iliterface are abstract and …
Measurement Of The Bs0 Lifetime And Production Rate With Ds- ℓ+ Combinations In Z Decays, D. Buskulic, M. Thulasidas
Measurement Of The Bs0 Lifetime And Production Rate With Ds- ℓ+ Combinations In Z Decays, D. Buskulic, M. Thulasidas
Research Collection School Of Computing and Information Systems
A precise determination of the effective Bs0→K+K− lifetime can be used to constrain contributions from physics beyond the Standard Model in the Bs0 meson system. Conventional approaches select B meson decay products that are significantly displaced from the B meson production vertex. As a consequence, B mesons with low decay times are suppressed, introducing a bias to the decay time spectrum which must be corrected. This analysis uses a technique that explicitly avoids a lifetime bias by using a neural network based trigger and event selection. Using 1.0fb−1 of data recorded by the LHCb experiment, the effective Bs0→K+K− lifetime is …

Measurement Of The Effective B Quark Fragmentation Function At The Z Resonance, Buskulic, D.; Et Al., M. Thulasidas
Research Collection School Of Computing and Information Systems
Using a sample of about 1.46 million hadronic Z decays collected between 1991 and 1993 with the ALEPH detector at LEP, the energy distribution of the B0 and B± mesons produced at the Z resonance is measured by reconstructing semileptonic decays B → ℓνℓD(X) or B→ ℓνℓD∗+(X). The charmed mesons are reconstructed through the decay modes D0 → K−π+, D0 → K−π+π−π+, D+ → K−π+π+ and D∗+→ D0π+. The neutrino energy is estimated from the missing energy in the lepton hemisphere. Accounting for B∗ and B∗∗ production, the shape of the scaled energy distribution xE(b) for mesons containing a b …

Measurements Of The B Baryon Lifetime, D. Buskulic, Manoj Thulasidas
Research Collection School Of Computing and Information Systems
The average lifetime of b-flavoured baryons measured with the OPAL detector is updated to include data collected between 1990 and 1994 at LEP. Bottom-flavoured baryons that decay semileptonically and produce aΛ baryon are identified through the correlation of the baryon number of theΛ and the electric charge of the lepton. To measure the lifetime, the decay point of the b baryon is estimated by theΛ-lepton vertex, and the observed distribution of decay lengths is fitted simultaneously in 874 right-sign and 384 wrong-sign combinations. In a separate method, the impact parameter distribution of the leptons is fitted in a subset of …

Folktales And Reality: The Social Construction Of Race In Chinese Tales, Lily Kong, Elaine Goh
Research Collection School of Social Sciences
This paper illustrates how folktales are a repository of primary material for the geographer. Using the example of The Strange Tales of Liaozhai, we discuss how these tales are not purely fictive constructs but constitute instead fictive, historical and projected realities. As an example of the value of such analysis, we discuss Chinese constructions of race as revealed in the tales.
Group Creativity And Technology, Keng Siau
Group Creativity And Technology, Keng Siau
Research Collection School Of Computing and Information Systems
Despite the popularity of brainstorming, research has shown that verbal brainstorming is not always effective in increasing group creativity. On the other hand, its electronic counterpart, electronic brainstorming, appears to produce much better results. Is technology the panacea for group idea generation? This paper first reviews the theory of group creativity and then examines the characteristics of electronic brainstorming that makes it more effective than verbal brainstorming. From the success of electronic brainstorming, it then argues that the use of technology might be the key to overcome the space and time constraints that are commonly faced by creativity groups.

Measurement Of The D*± Cross Section In Two Photon Collisions At Lep, D. Buskulic, M. Thulasidas
Research Collection School Of Computing and Information Systems
The inclusive production of D∗± mesons in photon-photon collisions has been measured by the Aleph experiment at LEP with a beam energy of 45 GeV. The D∗+ are detected in their decay to D0π+ with the D0 observed in three separate decay modes: (1) K−π+, (2) K−π+π0 and (3) K−π+π−π+, and analagously for the D∗− modes. A total of 33 events was observed from an integrated luminosity of 73 pb−1 which corresponds to a cross section for Σ(e+e−→ e+e−D∗±X) of 155 ± 33 ± 21 pb. This result is compatible with both the direct production γγ → cc in the …
Limit On B0s Oscillation Using A Jet Charge Method, D. Buskulic, M. Thulasidas
Limit On B0s Oscillation Using A Jet Charge Method, D. Buskulic, M. Thulasidas
Research Collection School Of Computing and Information Systems
A lower limit is set on the Bs0 meson oscillation parameter Δms using data collected from 1991 to 1994 by the ALEPH detector. Events with a high transverse momentum lepton and a reconstructed secondary vertex are used. The high transverse momentum leptons are produced mainly by b hadron decays, and the sign of the lepton indicates the particle/antiparticle final state in decays of neutral B mesons. The initial state is determined by a jet charge technique using both sides of the event. A maximum likelihood method is used to set a lower limit of Δms. The 95% confidence level lower …

Research Collection School Of Computing and Information Systems
An Expert Support System (ESS) provides expert advice to complement the knowledge of the decision maker, and is intended to support , rather than replace, the decision maker. The ESS technology provides two fundamental functions: (1) the ability to perform analyses and draw conclusions by providing users with expert opinions, judgments, evaluations and advice; (2) the ability to explain its reasoning and conclusions. The usefulness of expert support technology has been evaluated in a number of empirical studies. However these studies either examined the organizational impact of the technology [e.g., 1] or the use of the technology by single individuals …
