Spatial Exploration Patterns Determine Navigation Efficiency: Trade-Off Between Memory Demands And Distance Travelled, Tamas Makany, Edward S. Redhead, Itiel E. Dror Dec 2007

Spatial Exploration Patterns Determine Navigation Efficiency: Trade-Off Between Memory Demands And Distance Travelled, Tamas Makany, Edward S. Redhead, Itiel E. Dror

Research Collection Lee Kong Chian School Of Business

A total of 41 participants explored a novel square-shaped environment containing five identical boxes each hiding a visually distinct object. After an initial free exploration the participants were required to locate the objects first in a predetermined and subsequently in an optional order task. Two distinct exploration strategies emerged: Participants explored either along the main axes of the room (axial), or in a more spatially spread, circular pattern around the edges of the room (circular). These initial exploration strategies influenced the optimality of spatial navigation performance in the subsequent optional order task. The results reflect a trade-off between memory demands …

The Validity Of Assessment Centres For The Prediction Of Supervisory Performance Ratings: A Meta-Analysis, Eran Hermelin, Filip Lievens, Ivan T. Robertson Dec 2007

The Validity Of Assessment Centres For The Prediction Of Supervisory Performance Ratings: A Meta-Analysis, Eran Hermelin, Filip Lievens, Ivan T. Robertson

Research Collection Lee Kong Chian School Of Business

The current meta-analysis of the selection validity of assessment centres aims to update an earlier meta-analysis of assessment centre validity. To this end, we retrieved 26 studies and 27 validity coefficients (N=5850) relating the Overall Assessment Rating (OAR) to supervisory performance ratings. The current study obtained a corrected correlation of .28 between the OAR and supervisory job performance ratings (95% confidence interval .24 < =rho < =.32). It is further suggested that this validity estimate is likely to be conservative given that assessment centre validities tend to be affected by indirect range restriction.

Knowledge Narratives And Heterogeneity In Management Consultancy And Business Services, Robin Fincham, Timothy Adrian Robert Clark, Karen Handley, Andrew Sturdy Dec 2007

Knowledge Narratives And Heterogeneity In Management Consultancy And Business Services, Robin Fincham, Timothy Adrian Robert Clark, Karen Handley, Andrew Sturdy

Research Collection Lee Kong Chian School Of Business

In the professional services, diversification into various types of business advice has implications for knowledge boundaries. This is a sector of changing jurisdictional patterns and periodic reconstruction. Firms like large law practices that feed services into corporate clients have been merging to provide global coverage (Suddaby and Greenwood, 2001; Suddaby et al., 2004). But new specialisms in areas like consulting and IT are even more dynamic. Patterns such as the growth in outsourcing and movement into management consulting accounted for stupendous growth of the global accounting firms. These changes have themselves been overtaken, as the IT and systems giants muscled …

An Empirical Analysis Of Mobile Voice Service And Sms: A Structural Model, Youngsoo Kim, William B. Vogt, Ramayya Krishnan, Rahul Telang Dec 2007

An Empirical Analysis Of Mobile Voice Service And Sms: A Structural Model, Youngsoo Kim, William B. Vogt, Ramayya Krishnan, Rahul Telang

Research Collection School Of Computing and Information Systems

In addition to the wireless telephony boom, a similar exponential increasing trend in wireless data service - short message service (SMS) - is visible as technology advances. We develop a structural model to understand how mobile users behave, especially how they consume voice, and services. Specifically, we measure the own- and the cross-price elasticities of these services. The cross-price elasticity is of significant importance because marketing activities are critically influenced by whether the goods are substitutes or complements. The research context poses significant econometric challenges due to three-part tariff, sequential discrete plan choice and continuous quantity choices. Using detailed individual …

The Value-Congruence Model Of Memory For Emotional Experiences: An Explanation For Cultural Differences In Emotional Self-Reports, Shigehiro Oishi, Ulrich Schimmack, Ed Diener, Chu Kim-Prieto, Christie N. Scollon, Dong-Won Choi Nov 2007

The Value-Congruence Model Of Memory For Emotional Experiences: An Explanation For Cultural Differences In Emotional Self-Reports, Shigehiro Oishi, Ulrich Schimmack, Ed Diener, Chu Kim-Prieto, Christie N. Scollon, Dong-Won Choi

Research Collection School of Social Sciences

In 3 studies, the authors found support for the value-congruence model that accounts for cultural variations in memory for emotional experiences. In Study 1, the authors found that in the made-in-the-U.S. scenario condition, European Americans were more accurate than were Asian Americans in their retrospective frequency judgments of emotions. However, in the made-in-Japan scenario condition, European Americans were less accurate than were Asian Americans. In Study 2, the authors demonstrated that value orientation mediates the Culture X Type of Event congruence effect. In Study 3 (a daily event sampling study), the authors showed that the congruence effect was explained by …

Technological Knowledge, Product Relatedness, And Parent Control: The Effect On Ijv Survival, Dean Xu, Jane W. Lu Nov 2007

Technological Knowledge, Product Relatedness, And Parent Control: The Effect On Ijv Survival, Dean Xu, Jane W. Lu

Research Collection Lee Kong Chian School Of Business

This article examines the relationships among parent firm technological knowledge, parent-IJV product relatedness, parent control over the IJV, and IJV survival. Combining the knowledge-based perspective and institutional theory, we argue that parent control itself does not necessarily lead to higher IN survival; it contributes to IN survival when the parent firm has a high level of technological knowledge, and when the IJV is product-related to this parent. Results obtained from 1038 Japanese IJVs based in China indicate that both equity control and managerial control of a Japanese parent had a positive interaction effect, with the parent's technological knowledge, on IN …

State-Led Transborder Industrialization In Asia: A Note On Singapore's Manufacturing Enclaves In Vietnam And China, Caroline Yeoh, Wilfred Pow Ngee How Nov 2007

State-Led Transborder Industrialization In Asia: A Note On Singapore's Manufacturing Enclaves In Vietnam And China, Caroline Yeoh, Wilfred Pow Ngee How

Research Collection Lee Kong Chian School Of Business

State-led, market-driven interventions have been the hallmark of the Singapore `success storyÆ. This paper revisits SingaporeÆs state-enterprise strategy and takes a closer look at the portability of this strategy, in the framework of Regionalization21, a series of transborder industrialization experiments in Indonesia, Vietnam and China. These state-engineered projects, orchestrated to encapsulate economic space for Singapore-based firms to expand into the region, remain controversial. This strategic initiative is promulgated on the exportability of SingaporeÆs state credibility, systemic and operational efficiencies as well as technological competencies, to locations where these attributes are less distinct. We present evidence culled from surveys and interviews …

The Change In Corporate Transparency Of Korean Firms After The Asian Financial Crisis: An Analysis Using Analysts' Forecast Data, Jinho Chang, Young Jun Cho, Hyun-Han Shin Nov 2007

The Change In Corporate Transparency Of Korean Firms After The Asian Financial Crisis: An Analysis Using Analysts' Forecast Data, Jinho Chang, Young Jun Cho, Hyun-Han Shin

Research Collection School Of Accountancy

Using analysts' forecast error and forecast dispersion of firms covered by the I/B/E/S database, this study examines the change in information asymmetry of Korean firms around the financial crisis of 1997. Results show that the information asymmetry of Korean firms is lower after the financial crisis than before, implying that corporate transparency did, in effect, improve with the change in business environment. In addition, this study finds that chaebol firms have higher information asymmetry than non-chaebol firm, and also that the corporate transparency improvement of chaebol firms is not higher than that of non-chaebol firms in the post-crisis period despite …

Giving Voice To The Religious, Seow Hon Tan Oct 2007

Giving Voice To The Religious, Seow Hon Tan

Research Collection Yong Pung How School Of Law

The relevance of moral values endorsed by religious persons in public decision-making has often been debated. The issue comes to the fore again in relation to the debate on Section 377A of the Penal Code dealing with acts of gross indecency between males. With the flourishing of diverse viewpoints that is a natural consequence of a liberal democratic society, and with greater participation by an increasingly sophisticated citizenry online and in the media, particularly in a nation in which those without religious affiliations make up only 15 per cent of the population, the ground rules of public discourse must be …

The Eu's "Sanctions Paradox", Portela, Clara

Research Collection School of Social Sciences

The forthcoming Summit meeting between the European Union (EU) and Africa next December will be the first event of this kind in the past seven years. However, the row over the participation of Zimbabwe’s President, Robert Mugabe, is casting a shadow over the upcoming event: A number of African states have threatened to boycott the meeting if Zimbabwe's leader is not invited, while the British government has indicated that it will not attend the meeting if he does. At the root of this row is an “EU sanction”: a visa ban prohibiting the entry into EU territory to Zimbabwean high-rank …

Wage Inequality, Intergenerational Mobility, And Education In Singapore, Kong Weng Ho Oct 2007

Wage Inequality, Intergenerational Mobility, And Education In Singapore, Kong Weng Ho

Research Collection School Of Economics

Accompanying Singapore’s phenomenal economic growth over the past four decades has been a rapid increase in educational attainment over the years. In 1960, the mean years of schooling for residents aged 25 and over was 3.14 years; in 2006, it was 9.3 years. This dramatic increase in the supply of skilled labour in all sectors of the economy helped to power Singapore’s high growth rates over the past few decades of economic development, which also saw declining wage inequality and high upward intergenerational mobility in education. However, we need to ask if these trends will continue in the future and …

Connected Lives And Embeddedness: Reading Zelizer With Granovetter – A Review And Critique, Deirdre Caputo-Levine, Alwyn Lim, Celine. Wills Oct 2007

Connected Lives And Embeddedness: Reading Zelizer With Granovetter – A Review And Critique, Deirdre Caputo-Levine, Alwyn Lim, Celine. Wills

Research Collection School of Social Sciences

Our concern is to read Viviana Zelizer’s Purchase of Intimacy inrelation to Mark Granovetter’s embeddedness framework. We compare Zelizer’s connected-lives approach to the embeddedness literature in orderto tease out the similarities, differences, and improvements in the wayseconomic sociologists examine the intertwining of economic and socialbehavior. We argue that although Zelizer and Granovetter both focus onthis intermeshing of socioeconomic action, their perspectives reflect theirdiffering starting points: economic transactions or intimate relationships.We believe Zelizer’s connected-lives approach gives fresh insight to thenew economic sociology but we have some reservations regarding hertreatment of reciprocity and power in intimate relationships.

Tournaments With Ex Post Heterogeneous Agents, Theofanis Tsoulouhas, Kosmas Marinakis Oct 2007

Tournaments With Ex Post Heterogeneous Agents, Theofanis Tsoulouhas, Kosmas Marinakis

Research Collection School Of Economics

This paper compares relative performance evaluation via tournaments to absolute performance evaluation via piece rates when agents are heterogeneous ex post, to make the point that agent heterogeneity compromises the insurance function of tournaments. In particular, we show that the more heterogeneous agents are the less insurance can be offered through tournaments and the less dominant tournaments are over piece rates. Thus, absolute performance piece rates should be preferred when agents are highly heterogeneous. However, even with heterogeneous agents, tournaments become more desirable when the number of agents or the uncertainty about the common shock increases sufficiently.

Direction-Of-Change Forecasts Based On Conditional Variance, Skewness And Kurtosis Dynamics: International Evidence, Peter F. Christoffersen, Francis X. Diebold, Roberto S. Mariano, Anthony S. Tay, Yiu Kuen Tse Oct 2007

Direction-Of-Change Forecasts Based On Conditional Variance, Skewness And Kurtosis Dynamics: International Evidence, Peter F. Christoffersen, Francis X. Diebold, Roberto S. Mariano, Anthony S. Tay, Yiu Kuen Tse

Research Collection School Of Economics

Recent theoretical work has revealed a direct connection between asset return volatility forecastability and asset return sign forecastability. This suggests that the pervasive volatility forecastability in equity returns could, via induced sign forecastability, be used to produce direction-of change forecasts useful for market timing. We attempt to do so in an international sample of developed equity markets, with some success, as assessed by formal probability forecast scoring rules such as the Brier score. An important ingredient is our conditioning not only on conditional mean and variance information, but also conditional skewness and kurtosis information, when forming direction-of-change forecasts.

Cross-Cultural Differences In Learning And Education: Stereotypes, Myths And Realities, Gerhard Apfelthaler, Katrin Hansen, Stephan Keuchel, Christa Mueller, Martin Neubauer, Siow-Heng Ong, Nirundon Tapachai

Research Collection Lee Kong Chian School Of Business

Despite the fact that both learning styles and cross-cultural differences have been important research topics for decades, surprisingly little work has been done on comparisons of learning behaviour across cultures and its impact for teachers working in culturally mixed settings. This chapter is based on a research project funded by the European Union seeking to provide fresh knowledge on cross-national differences in attitudes towards learning of students from selected countries. It reports on the results from Austria, Germany, Singapore and Thailand and outlines some of the implications for teaching in higher education.

Norming "Moderation'' In An "Iconic Target'': Public Policy And The Regulation Of Religious Anxieties In Singapore, Eugene K. B. Tan Oct 2007

Norming "Moderation'' In An "Iconic Target'': Public Policy And The Regulation Of Religious Anxieties In Singapore, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

The proposed research will examine Singapore’s response to terrorism post September 11, in particular the maintenance of a “moderate mainstream” Muslim community as a bulwark against the fraying of harmonious ethnic relations. In light of the global concern—and often paranoia—with diasporic Islam, Islamic religious institutions and civil society have been portrayed in the popular media as hotbeds of radicalism, promoters of hatred, and recruiters for a ‘conflict of civilization’ between the Muslim world and the modern world. Islamist attacks in Madrid and London have since brought increased urgency to the question of how to contain or moderate Islamic radicalism among …

Un-Balanced Economic Growth, Hing-Man Leung Sep 2007

Un-Balanced Economic Growth, Hing-Man Leung

Research Collection School Of Economics

Since the elasticity of substitution between capital and labor is not always one, and since technical progress is not always Harrod-neutral, it is desirable to have an endogenous growth model that admits all sizes of the elasticity and all known technology modes. We derive an equation to do just that, fully describing the per capita income growth rate at all times. It shows a typical economy needing hundreds if not thousands of years to reach its long term growth rate, leading to the conclusion that even the short run may be very long indeed.

A Hybrid Approach To Case Teaching, Swee Liang Tan, Roy Jin Hou Ng Sep 2007

A Hybrid Approach To Case Teaching, Swee Liang Tan, Roy Jin Hou Ng

Research Collection School Of Economics

We structure case based teaching using a combination of computer-support technology and in-class activities. We create and design an on-line learning tool, Case Study On-line (CSOL) that enables instructor to structure the delivery of teaching resources and set up assignment tasks in the system. The tool enables tasks to be set in a way that they can be completed sequentially, and learning resources can be accessed only when required by students. Upon submission of their assignments, students can promptly receive instructor’s explanations to the tasks. Follow up activities take place in class, with the objective to promote active learning.

Modeling Country Risks: An Asian Perspective, Swee Liang Tan, G. K. Randolph Tan Sep 2007

Modeling Country Risks: An Asian Perspective, Swee Liang Tan, G. K. Randolph Tan

Research Collection School Of Economics

This paper investigates the use of the Markov Regime Switching Model (MRSM) as a means to track changes in the levels of investor confidence. It also assesses the probabilities of a country switching between different regimes using the transition probability matrix. A maximum of three possible levels or regimes of risk – low, intermediate and high volatility regimes, is considered. From the smoothed probabilities calculated for different regimes, this paper makes inferences about timings of debt crisis. Comparing Brazil, Mexico, the Philippines and Indonesia in particular, we date the onset and subsequent dissolution of crisis-induced panic. We give interpretations of …

Grist For The Sceptic's Mill: Rwanda And The African Peer Review Mechanism, Eduard Jordaan Sep 2007

Grist For The Sceptic's Mill: Rwanda And The African Peer Review Mechanism, Eduard Jordaan

Research Collection School of Social Sciences

The article delves into the impact of the African Peer Review Mechanism (APRM) to Rwanda's achievement of greater democracy and respect for political freedom. It aims to show the improbability that the APRM can influence the country due to its insufficient ability and volition to pressure further democratization and respect for political rights on Rwandan government, the APRM's optimistic view of political governance, and the APR Heads of State Forum's ratification of a program of action discounting the issues of democracy and political freedom. The author stresses that the weaknesses of APRM may be attributed to the existing reduced authorization …

The Wto Trade Effect, Pao Li Chang, Myoung-Jae Lee Sep 2007

The Wto Trade Effect, Pao Li Chang, Myoung-Jae Lee

Research Collection School Of Economics

Rose (2004) showed that the WTO or its predecessor, the GATT, did not promote trade, based on conventional econometric analysis of gravity-type equations of trade. We argue that conclusions regarding the GATT/WTO trade effect based on gravity-type equations are arbitrary and subject to parametric misspecifications. We propose using nonparametric matching methods to estimate the 'treatment effect' of GATT/WTO membership, and permutation-based inferential procedures for assessing statistical significance of the estimated effects. A sensitivity analysis following Rosenbaum (2002) is then used to evaluate the sensitivity of our estimation results to potential selection biases. Contrary to Rose (2004), we find the effect …

Forecasting The Car Penetration Rate (Cpr) In China: A Nonparametric Approach, Sainan Jin, Liangjun Su Sep 2007

Forecasting The Car Penetration Rate (Cpr) In China: A Nonparametric Approach, Sainan Jin, Liangjun Su

Research Collection School Of Economics

With strong economic growth, the auto industry has made great breakthroughs in recent years and has become a backbone industry in China, while cars play an increasingly important role, and are now the principal part of the auto industry. Both China's government and academic circles take strong interest in the prediction of CPR (i.e. car penetration rate or cars per thousand people), which will be the main guidance for the future industry policy. We summarize the existing problems in recent research and propose to use nonparametric methods to estimate the CPR and its elasticity with respect to GDP per capita …
