Functional Relations Among Constructs In The Same Content Domain At Different Levels Of Analysis: A Typology Of Composition Models, David Chan Apr 1998

Functional Relations Among Constructs In The Same Content Domain At Different Levels Of Analysis: A Typology Of Composition Models, David Chan

Research Collection School of Social Sciences

Composition models specify the functional relationships among phenomena or constructs at different levels of analysis (e.g., individual level, team level, organizational level) that reference essentially the same content but that are qualitatively different at different levels (M. T. Hannan, 1971, K. H. Roberts, C. L. Hulin, & D. M. Rousseau, 1978, D. M. Rousseau, 1985). Specifying adequate composition models is a critical component of good multilevel research. A typology of composition models is proposed to provide a framework for organizing, evaluating, and developing constructs and theories in multilevel research. Five basic forms of composition are described and illustrated. Implications of …

Managing Creativity In Organizations: A Total System Approach, Gilbert Tan Mar 1998

Managing Creativity In Organizations: A Total System Approach, Gilbert Tan

Research Collection Lee Kong Chian School Of Business

Organizations need creativity to adapt to the fast-changing environment and revitalize itself. In response to this need, managers have invested in various single approaches, such as, creativity training programmes, team-building, and leadership development to improve creativity. This paper argues that managing creativity in organization is a complex problem and thus requires a more integrated approach. In this paper, I have provided a theoretical framework to explain how managers can foster and sustain creativity in their organizations using a total systems approach. In the framework, I depict the organization as having four subsystems, namely, culture, techno-structural subsystems, management and people. Each …

Refocusing On Qualitative Methods: Problems And Prospects For Research In A Specific Asian Context, Lily Kong Mar 1998

Refocusing On Qualitative Methods: Problems And Prospects For Research In A Specific Asian Context, Lily Kong

Research Collection School of Social Sciences

A recent issue of Area (1996, Volume 28.2) devoted space to six papers on focus groups, attesting to their increasing importance as a means of obtaining qualitative data. The papers provided interesting insights into the use of focus groups in specific research and cultural contexts, and raised three main issues in my mind. The first is a continuing misunderstanding as to the nature of knowledge, which surfaces in discussions of, and approaches to, the use of qualitative methods such as focus groups. The second is the range of related techniques that are actually involved in the qualitative method, known as …

Telling Tales: Management Gurus' Narratives And The Construction Of Managerial Identity, Timothy Adrian Robert Clark, Graeme Salaman Mar 1998

Telling Tales: Management Gurus' Narratives And The Construction Of Managerial Identity, Timothy Adrian Robert Clark, Graeme Salaman

Research Collection Lee Kong Chian School Of Business

This paper examines the reasons for the apparently powerful impact of management gurus' ideas (i.e. guru theory) on senior managers. An examination of the limited literature on management gurus and other related literatures suggests three explanations for the appeal of guru theory for senior managers. The first set of explanations relates to various features of management work which may heighten managers' receptivity to guru ideas. The second set focuses on the gurus themselves and emphasizes the form in which they are presented (i.e. public performances). The final set of explanations highlights the importance of the socioeconomic and cultural context within …

Measurement Of Triple Gauge-Boson Couplings At 172 Gev, Barate, R.; Et Al, M. Thulasidas Mar 1998

Measurement Of Triple Gauge-Boson Couplings At 172 Gev, Barate, R.; Et Al, M. Thulasidas

Research Collection School Of Computing and Information Systems

The triple gauge-boson couplings, αWΦ, αW and αBΦ, have been measured using 34 semileptonically and 54 hadronically decaying W+W− candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb−1. The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W+W− events. The results are in agreement with the Standard Model expectation.

Four-Jet Final State Production In E+E- Collisions At Centre-Of-Mass Energies Ranging From 130 To 184 Gev, R. Barate, Manoj Thulasidas Feb 1998

Four-Jet Final State Production In E+E- Collisions At Centre-Of-Mass Energies Ranging From 130 To 184 Gev, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

The four jet topology is analysed in the ALEPH data taken between November 1995 and October 1997, at centre-of-mass energies ranging from 130 to 184 GeV. While an unexpected accumulation of events with a dijet mass sum around 105 GeV/c 2 had been observed during the first run in 1995 at 130/136 GeV, corresponding to an integrated luminosity of 5.7 pb1 , no significant dierences between data and standard model prediction is seen, either in the high energy runs (81.1 pb1 taken at centre-of-mass energies from 161 to 184 GeV) or in the 7.1 pb1 recorded during a new short …

A Visual Object-Relationship Query Language For User-Database Interaction, Keng Siau Feb 1998

A Visual Object-Relationship Query Language For User-Database Interaction, Keng Siau

Research Collection School Of Computing and Information Systems

User–database interaction has a direct and immediate effect on the effectiveness and efficiency of database end users. Traditional query languages like SQL and QBE require end users to understand the underlying data structure in the database. This is a burden on end users, especially novice end users who have little technical knowledge or understanding of database. To alleviate the need for end users to know the logical database organization, this paper proposes the use of an object–relationship (OR) model and a formal high-level visual query language as the interface. Using this interface, end users communicate only domain knowledge with the …

Creating The 'Right' Impression: Towards A Dramaturgy Of Management Consultancy, Timothy Adrian Robert Clark, Graeme Salaman Jan 1998

Creating The 'Right' Impression: Towards A Dramaturgy Of Management Consultancy, Timothy Adrian Robert Clark, Graeme Salaman

Research Collection Lee Kong Chian School Of Business

This article adopts a novel approach by examining the activities of management consultants in terms of the dramaturgical metaphor. This is a useful framework within which to illuminate their activities since a number of service characteristics combine to create a context within which the key task of management consultants is to convince clients of their quality and value. Impression management is therefore a core feature of consultancy work. In this sense management consultants are viewed as systems of persuasion creating compelling images which persuade clients of their quality and worth. This argument is illustrated with reference to the activities of …

A New Look At Within-Source Interrater Reliability Of 360-Degree Feedback Ratings, Gary J. Greguras, Chet Robie Jan 1998

A New Look At Within-Source Interrater Reliability Of 360-Degree Feedback Ratings, Gary J. Greguras, Chet Robie

Research Collection Lee Kong Chian School Of Business

This study investigated within-source interrater reliability of supervisor, peer, and subordinate feedback ratings made for managerial development. Raters provided 360-degree feedback ratings on a sample of 153 managers. Using generalizability theory, results indicated that little within-source agreement exists; a large portion of the error variance is attributable to the combined rater main effect and Rater X Ratee effect; more raters are needed than currently used to reach acceptable levels of reliability; supervisors are the most reliable with trivial differences between peers and subordinates when the numbers of raters and items are held constant; and peers are the most reliable, followed …

Lee Kuan Yew And His Use Of Spatial-Orientational Metaphors, Siow Heng Ong Jan 1998

Lee Kuan Yew And His Use Of Spatial-Orientational Metaphors, Siow Heng Ong

Research Collection Lee Kong Chian School Of Business

The Prime Minister's message to the nation after Singapore separated from Malaysia was one of consolidation and moving ahead. This was not an easy task for the speaker as the year before Singapore separated from Malaysia, the race riots had claimed 34 lives.1 These riots were even more prolonged than the Hertogh riots of 1950. Maintaining racial harmony and social integration was an uphill task. The hope for consolidation and a united sense of nationhood seemed distant.

From Entrepot To Nic: Economic And Structural Policy Aspects Of Singapore's Development, Jochen Wirtz, Thomas Menkhoff Jan 1998

From Entrepot To Nic: Economic And Structural Policy Aspects Of Singapore's Development, Jochen Wirtz, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

This paper describes the development of Singapore from an entrepot to an industrialized economy and analyzes the role of its structural and industrial policies as one important factor in this success story. The advance of Singapore to an industrialized economy can be structured into four phases. Phase I, the early phase from 1959 to the mid-1960s is characterized by an import substitution policy followed together with Malaysia. Phase II describes the enhanced export-orientation and industrialization from 1967 to 1973. Phase III includes the industrial restructuring from 1973 to 1984. Phase IV describes the development towards diversification of the industrial base …

Search For Supersymmetry With A Dominant R-Parity Violating Llē Coupling In E+E- Collisions At Centre-Of-Mass Energies Of 130 Gev To 172 Gev, R. Barate, M. Thulasidas Jan 1998

Search For Supersymmetry With A Dominant R-Parity Violating Llē Coupling In E+E- Collisions At Centre-Of-Mass Energies Of 130 Gev To 172 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LLE¯LLE¯ coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130–172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This is translated into lower limits on the mass of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, charginos with masses less than 73 GeV/c2c2 and neutralinos with masses less than 23 GeV/c2c2 are excluded at 95% confidence level for any generation structure of the LLE¯LLE¯ coupling, and for neutralino, slepton …

Measurement Of The Axial-Vector Τ Spectral Functions And Determination Of Αs (M2Τ) From Hadronic Τ Decays, R. Barate, M. Thulasidas Jan 1998

Measurement Of The Axial-Vector Τ Spectral Functions And Determination Of Αs (M2Τ) From Hadronic Τ Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

An analysis based on 124 000 selected ττ pairs recorded by the ALEPH detector at LEP provides the vector (V)(V) and axial-vector (A)(A) spectral functions of hadronic ττ decays together with their total widths. This allows the evaluation of finite energy chiral sum rules that are weighted integrals over the (V−A)(V−A) spectral functions. In addition, a precise measurement of αsαs along with a determination of nonperturbative contributions at the ττ mass scale is performed. The experimentally and theoretically most robust determination of αs(M2τ)αs(Mτ2) is obtained from the (V+A)(V+A) fit that yields αs(M2τ)=0.334±0.022αs(Mτ2)=0.334±0.022 giving αs(M2Z)=0.1202±0.0027αs(MZ2)=0.1202±0.0027 after the extrapolation to the mass …

Search For Evidence Of Compositeness At Lep I, R. Barate, M. Thulasidas Jan 1998

Search For Evidence Of Compositeness At Lep I, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

Extensive searches for evidence of compositeness of quarks and leptons have been made in the complete set of ALEPH data from LEP running at the Z peak. These include searches for radiative and weak decays of excited fermions, produced either in pairs or singly, and a scalar partner of the Z. Coupling and branching ratio limits deduced from these searches are presented.

Measurement Of The Fraction Of Hadronic Z Decays Into Charm Quark Pairs, R. Barate, M. Thulasidas Jan 1998

Measurement Of The Fraction Of Hadronic Z Decays Into Charm Quark Pairs, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The full statistics of hadronic Z decays collected with the ALEPH detector are analysed to measure, by three methods, the ratio, RcRc, of the partial decay width of the Z into cc¯cc¯ quarks to the total hadronic width. One method uses the inclusive pp and p⊥p⊥ spectra of electrons. The other two use a double-tagging technique to measure RcRc independently of the charm-tagging efficiency. In one, the tagging procedure uses the reconstruction of high momentum charmed mesons (D∗+D∗+, D+D+ and \({\rm D^0}$) to detect the charm quarks. In the other, a charm quark is tagged from the D∗D∗'s reconstructed in …

Searches For Charginos And Neutralinos In E+E- Collisions At √S = 161 And 172 Gev, R. Barate, M. Thulasidas Jan 1998

Searches For Charginos And Neutralinos In E+E- Collisions At √S = 161 And 172 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The data recorded by the ALEPH detector at centre-of-mass energies of 161, 170, and 172 GeV are analysed for signals of chargino and neutralino production. No evidence of a signal is found, although candidate events consistent with the expectations from Standard Model processes are observed. Limits at 95% C.L. on the production cross sections are derived and bounds on the parameters of the Minimal Supersymmetric Standard Model are set. The lower limit on the mass of the lightest ch is 85.5 GeV/c2GeV/c2 for gaugino-like charginos (μ=−500GeV/c2μ=−500GeV/c2), and 85.0 GeV/c2GeV/c2 for Higgsino-like charginos (M2=500GeV/c2M2=500GeV/c2), for heavy sneutrinos (Mν~≥200GeV/c2Mν~≥200GeV/c2) and tanβ=2–√tan⁡β=2.

Study Of B0s Oscillations And Lifetime Using Fully Reconstructed D̄S Decays, R. Barate, M. Thulasidas Jan 1998

Study Of B0s Oscillations And Lifetime Using Fully Reconstructed D̄S Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A search for B0sBs0 oscillations is performed using approximately 4 million Z→qq¯Z→qq¯ events collected by the ALEPH experiment during 1991–1995. B0sBs0 candidates are partially reconstructed by combining tracks with fully reconstructed D−sDs− candidates. The B0sBs0 production flavour is estimated from the sign of the opposite hemisphere charge, a fragmentation kaon in the same hemisphere, or a lepton in the opposite hemisphere. From a total sample of 1620 candidates, with a B0sBs0 purity estimated to be 22%, all values of ΔmsΔms below 3.9 ps−1−1 and between 6.5 and 8.8 ps−1−1 are excluded at 95% CL. From the same sample, the B0sBs0 …

Evaluating Information Modeling Methods – A Review, Keng Siau, M. Rossi Jan 1998

Evaluating Information Modeling Methods – A Review, Keng Siau, M. Rossi

Research Collection School Of Computing and Information Systems

Hundreds of modeling methods are in existence today, yet practitioners and researchers are zealously “producing” new modeling methods. The “blooming” of modeling methods is not the problem; the lack of standardized techniques for evaluating them is. To further complicate the matter, most of the modeling methods are introduced based on common sense and intuition. Theoretical foundations and empirical evidence are severely lacking. With the current state of affairs, evaluation of modeling methods has become necessary. Comparing modeling methods provides us with the necessary knowledge and understanding on the strengths and weaknesses of each method. This knowledge can also guide us …

The End Of Secrecy, Ann Florini Jan 1998

The End Of Secrecy, Ann Florini

Research Collection School of Social Sciences

Two standards of behavior are slugging it out around the world. Advocates of well-established norms such as corporate privacy and national sovereignty want to hide information from prying eyes, while promoters of transparency tout it as the solution to everything from international financial crises to arms races and street crime. Just what is transparency? Put simply, transparency is the opposite of secrecy. Secrecy means deliberately hiding your actions; transparency means deliberately revealing them. This element of volition makes the growing acceptance of transparency much more than a resigned surrender to the technologically facilitated intrusiveness of the Information Age. Transparency is …

Comparing The Discourse Of Popular Politics In Korea And China: From Civil Society To Social Movements, William A. Callahan Jan 1998

Comparing The Discourse Of Popular Politics In Korea And China: From Civil Society To Social Movements, William A. Callahan

Research Collection School of Social Sciences

The Korea Journal’s series of articles addressing the question of civil society are a timely addition to the struggle over the discourse of democracy which is common to many countries in Pacific Asia. Since Professor Han Sang-Jin’s article does an excellent job of critically summarizing Chung Chulhee, Cho Hein and David Steinberg’s arti cles on Korean civil society, it seems that there is not much more to be said on the topic. To add to this discussion I will try to expand the discourse geographically and conceptually. Geographically, I will compare the discourse of popular politics in Korea with that …

Liberalism And Multiculturalism: The Politics Of Indifference, Chandran Kukathas Jan 1998

Liberalism And Multiculturalism: The Politics Of Indifference, Chandran Kukathas

Research Collection School of Social Sciences

In modern societies, particularly the societies of the liberal democratic West, cultural diversity poses a challenge not only to the makers of government policy, but also to the philosopher looking to understand how it might be possible-in principle-for people of different ways to live together. The challenge is posed because society's institutions have been challenged, as the members of different groups have demanded "recognition." They have demanded not simply recognition of their claims to a (just) share of the social pie but, more important, recognition of their distinct identities as members of particular cultural communities within society. The persistence and, …

O Arquipélago Liberal: Contornos De Um Conceito De Liberalismo (In Portuguese), Chandran Kukathas, Ana Barradas

Research Collection School of Social Sciences

O objectivo desta comunicação consiste em delinear e defender um con- ceito de liberalismo. Na medida em que o liberalismo proporciona uma teoria sobre a natureza de uma sociedade livre, apresenta os contornos de uma teoria da liberdade particular. Mas a sua preocupação mais imediata é defen- der um modelo peculiar de sociedade livre. A natureza deste modelo talvez possa ser melhor entendida, pelo menos inicialmente, se considerarmos a teoria aqui apresentada como fazendo a defesa de um aspecto de determinada pergunta. Tal pergunta consiste em saber se o liberalismo identifica um conjunto de valores e padrões morais aos quais …

The Ideology Of Miss Thailand In National, Consumerist And Transnational Space, William A. Callahan Jan 1998

The Ideology Of Miss Thailand In National, Consumerist And Transnational Space, William A. Callahan

Research Collection School of Social Sciences

Every morning at 8:00 a.m. (with flag-raising) and every evening at 6:00 P.M. (with flag lowering) the official symbolic identity of Thai- land is displayed - by state order - on television. These displays are a graphic daily reminder of how nationalism, the military, and the media are tightly bound together in Thailand. Though it seems like a timeless tradition of respect for essential national symbols, this tele- vized ritual is the result of a "revolutionary order" issued by the right-wing dictators who took power with the brutal October 6, 1976, massacre and military coup.1 These media productions are part …

An Optimal Procedure For The Resource-Constrained Project Scheduling Problem With Discounted Cash Flows And Generalized Precedence Relations, Bert De Reyck, Willy Herroelen Jan 1998

An Optimal Procedure For The Resource-Constrained Project Scheduling Problem With Discounted Cash Flows And Generalized Precedence Relations, Bert De Reyck, Willy Herroelen

Research Collection Lee Kong Chian School Of Business

In this paper, we consider the resource-constrained project scheduling problem (RCPSP) with discounted cash flows and generalized precedence relations (RCPSPDC-GPR). The RCPSPDC-GPR extends the RCPSP to (a) arbitrary minimal and maximal time lags between the starting and completion times of activities and (b) the non-regular objective function of maximizing the net present value of the project with positive and/or negative cash flows associated with the activities. To the best of our knowledge, the literature on the RCPSPDC-GPR is completely void. We present a depth-first branch-and-bound algorithm in which the nodes in the search tree represent the original project network extended …

The Conditional Heteroscedasticity Of The Yen-Dollar Exchange Rates, Yiu Kuen Tse Jan 1998

The Conditional Heteroscedasticity Of The Yen-Dollar Exchange Rates, Yiu Kuen Tse

Research Collection School Of Economics

This paper examines the conditional heteroscedasticity of the yen-dollar exchange rate. A model is constructed by extending the asymmetric power autoregressive conditional heteroscedasticity model to a process that is fractionally integrated. It is found that, unlike the equity markets, the appreciation and depreciation shocks of the yen against the dollar have similar effects on future volatilities. Although the results reject both the stable and the integrated models, our analysis of the response coefficients of the past shocks and the application of the models to the estimation of the capital requirements for trading the currencies show that there are no substantial …
