Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet Nov 2015

Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet

Research Collection School of Social Sciences

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that …

Mediation Goes Global In Singapore, George S. C. Lim, Eunice Chua Nov 2015

Mediation Goes Global In Singapore, George S. C. Lim, Eunice Chua

Research Collection Yong Pung How School Of Law

Singapore has positioned itself as an international dispute resolution hub in Asia by providing a complete suite of services for international arbitration, international litigation and mediation through the Singapore International Arbitration Centre (“SIAC”), the Singapore International Commercial Court (“SICC”) and the Singapore International Mediation Centre (“SIMC”). SICC and SIMC build on Singapore’s reputation for quality legal services, including its status as the most preferred seat of arbitration in Asia and the third most preferred seat of arbitration in the world.[1] They bring more options to parties facing cross-border disputes who need tailored solutions that meet their needs.

Enriching The Perceived Norms Perspective Of Intergenerational Cultural Transmission: The Roles Of Norm Reference Groups And Norm Adherence/Deviance Motive, Angela K. Y. Leung Nov 2015

Enriching The Perceived Norms Perspective Of Intergenerational Cultural Transmission: The Roles Of Norm Reference Groups And Norm Adherence/Deviance Motive, Angela K. Y. Leung

Research Collection School of Social Sciences

In this article, I seek to apply Morris and Liu (2015)’s functionalist account of subjective norms to enrich Tam’s (2015) perceived norms perspective of intergenerational cultural transmission. This enriched approach recognizes parents’ choice to construct their transmission preferences that include norms of a nonmainstream reference group and that support a norm deviance motive. In this light, I review empirical evidence examining some factors that affect whether parents reference on peer or elite groups or they tend toward norm adherence or deviance in the transmission process. Acknowledging these variants allows the bridge of value transmission and value change studies that are …

Luxury And Gender In European Towns, 1700–1914. Deborah Simonton, Marjo Kaartinen, And Anne Montenach (Eds), Fiona Williamson Nov 2015

Luxury And Gender In European Towns, 1700–1914. Deborah Simonton, Marjo Kaartinen, And Anne Montenach (Eds), Fiona Williamson

Research Collection College of Integrative Studies

The concept and consumption of ‘luxury’ was at the heart of many preconceptions about gender, status and identity during the eighteenth and nineteenth centuries. Acting as a determinant of—yet also blurring the boundaries of—social class, luxury was a fundamental component of identity for both men and women. Towns operated as hubs in the luxury goods trade and urban inhabitants were the main producers and consumers of the newest fashions. This collection of essays, stemming from the pan-European Gender in European Towns Network launched in 2006, seeks to explore how luxury connected to, and shaped, urban senses of self and status …

The Brief Aggression Questionnaire: Reliability, Validity, And Structure, Gregory D. Webster, C. Nathan Dewall, Richard S. Pond, Timothy Deckman, Peter K. Jonason, Bonnie M. Le, Austin Lee Nichols, Tatiana Orozco Schember, Laura C. Crysel, Benjamin S. Crosier, C. Veronica Smith, Elizabeth Layne Paddock

Research Collection Lee Kong Chian School Of Business

In contexts that increasingly demand brief self-report measures (e.g., experience sampling, longitudinal and field studies), researchers seek succinct surveys that maintain reliability and validity. One such measure is the 12-item Brief Aggression Questionnaire (BAQ; Webster et al., 2014), which uses 4 3-item subscales: Physical Aggression, Verbal Aggression, Anger, and Hostility. Although prior work suggests the BAQ's scores are reliable and valid, we addressed some lingering concerns. Across 3 studies (N = 1,279), we found that the BAQ had a 4-factor structure, possessed long-term test–retest reliability across 12 weeks, predicted differences in behavioral aggression over time in a laboratory experiment, …

Magna Carta Then And Now: A Symbol Of Freedom And Equal Rights For All, Eugene K. B. Tan, Jack Tsen-Ta Lee Nov 2015

Magna Carta Then And Now: A Symbol Of Freedom And Equal Rights For All, Eugene K. B. Tan, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

Magna Carta became applicable to Singapore in 1826 when a court system administering English law was established in the Straits Settlements. This remained the case through Singapore’s evolution from Crown colony to independent republic. The Great Charter only ceased to apply in 1993, when Parliament enacted the Application of English Law Act to clarify which colonial laws were still part of Singapore law. Nonetheless, Magna Carta’s legacy in Singapore continues in a number of ways. Principles such as due process of law and the supremacy of law are cornerstones of the rule of law, vital to the success, stability and …

Improved Inferences For Spatial Regression Models, Shew Fan Liu, Zhenlin Yang Nov 2015

Improved Inferences For Spatial Regression Models, Shew Fan Liu, Zhenlin Yang

Research Collection School Of Economics

The quasi-maximum likelihood (QML) method is popular in the estimation and inference for spatial regression models. However, the QML estimators (QMLEs) of the spatial parameters can be quite biased and hence the standard inferences for the regression coefficients (based on t-ratios) can be seriously affected. This issue, however, has not been addressed. The QMLEs of the spatial parameters can be bias-corrected based on the general method of Yang (2015b, J. of Econometrics 186, 178-200). In this paper, we demonstrate that by simply replacing the QMLEs of the spatial parameters by their bias-corrected versions, the usual t-ratios for the regression coefficients …

Testing For Multiple Bubbles: Limit Theory Of Real-Time Detectors, Peter C. B. Phillips, Shuping Shi, Jun Yu Nov 2015

Testing For Multiple Bubbles: Limit Theory Of Real-Time Detectors, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

This article provides the limit theory of real-time dating algorithms for bubble detection that were suggested in Phillips, Wu, and Yu (PWY; International Economic Review 52 [2011], 201-26) and in a companion paper by the present authors (Phillips, Shi, and Yu, 2015; PSY; International Economic Review 56 [2015a], 1099-1134. Bubbles are modeled using mildly explosive bubble episodes that are embedded within longer periods where the data evolve as a stochastic trend, thereby capturing normal market behavior as well as exuberance and collapse. Both the PWY and PSY estimates rely on recursive right-tailed unit root tests (each with a different recursive …

Testing For Multiple Bubbles: Historical Episodes Of Exuberance And Collapse In The S&P 500, Peter C. B. Phillips, Shuping Shi, Jun Yu Nov 2015

Testing For Multiple Bubbles: Historical Episodes Of Exuberance And Collapse In The S&P 500, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

Recent work on econometric detection mechanisms has shown the effectiveness of recursive procedures in identifying and dating financial bubbles in real time. These procedures are useful as warning alerts in surveillance strategies conducted by central banks and fiscal regulators with real-time data. Use of these methods over long historical periods presents a more serious econometric challenge due to the complexity of the nonlinear structure and break mechanisms that are inherent in multiple-bubble phenomena within the same sample period. To meet this challenge, this article develops a new recursive flexible window method that is better suited for practical implementation with long …

Optimal Taxation And Debt With Uninsurable Risks To Human Capital Accumulation, Piero Gottardi, Atsushi Kajii, Tomoyuki Nakajima Nov 2015

Optimal Taxation And Debt With Uninsurable Risks To Human Capital Accumulation, Piero Gottardi, Atsushi Kajii, Tomoyuki Nakajima

Research Collection School Of Economics

We consider an economy where individuals face uninsurable risks to their human capital accumulation and analyze the optimal level of linear taxes on capital and labor income together with the optimal path of government debt. We show that in the presence of such risks, it is beneficial to tax both labor and capital and to issue public debt. We also assess the quantitative importance of these findings, and show that the benefits of government debt and capital taxes both increase with the magnitude of idiosyncratic risks and the degree of relative risk aversion.

A Bayesian Chi-Squared Test For Hypothesis Testing, Yong Li, Xiaobin Liu, Jun Yu Nov 2015

A Bayesian Chi-Squared Test For Hypothesis Testing, Yong Li, Xiaobin Liu, Jun Yu

Research Collection School Of Economics

A new Bayesian test statistic is proposed to test a point null hypothesis based on a quadratic loss. The proposed test statistic may be regarded as the Bayesian version of the Lagrange multiplier test. Its asymptotic distribution is obtained based on a set of regular conditions and follows a chi-squared distribution when the null hypothesis is correct. The new statistic has several important advantages that make it appealing in practical applications. First, it is well-defined under improper prior distributions. Second, it avoids Jeffrey-Lindley's paradox. Third, it always takes a non-negative value and is relatively easy to compute, even for models …

Research Collection Lee Kong Chian School Of Business

The financial system is on the verge of massive disruption. Innovative competitors operating on sleek business models and offering new alternative services are entering at the bottom of the market, where gross margins are low and latent demand is high. As these new entrants scale and progress through higher market segments, they will erode incumbent pricing power.

Inquiring Into Activist Publics In Chronic Environmental Issues: Use Of The Mutual Gains Approach For Breaking A Deadlock, Soojin Kim, Jeong-Nam Kim, Laishan Tam, Gwang Tae Kim Nov 2015

Inquiring Into Activist Publics In Chronic Environmental Issues: Use Of The Mutual Gains Approach For Breaking A Deadlock, Soojin Kim, Jeong-Nam Kim, Laishan Tam, Gwang Tae Kim

Research Collection Lee Kong Chian School Of Business

This study aims to understand different publics’ communicative behaviors for problem solving surrounding an oil spill issue in Korea. Specifically, it explores the differences between chronic activists and other types of publics who were affected by this chronic environmental issue. A total of 24 interviews were conducted, from which five different types of publics were identified. The findings suggest that the majority of activists who are currently working on the issue are closed-chronic activists, which are slightly different from Ni and Kim’s findings on chronic activists’ communicative behaviors. Interviews were also conducted with five communication experts to propose viable conflict …

Competition Of The Informed: Does The Presence Of Short Sellers Affect Insider Selling?, Massimo Massa, Wenlan Qian, Weibiao Xu, Hong Zhang Nov 2015

Competition Of The Informed: Does The Presence Of Short Sellers Affect Insider Selling?, Massimo Massa, Wenlan Qian, Weibiao Xu, Hong Zhang

Research Collection Lee Kong Chian School Of Business

We study how the presence of short sellers affects the incentives of the insiders to trade on negative information. We show it induces insiders to sell more (shares from their existing stakes) and trade faster to preempt the potential competition from short sellers. An experiment and instrumental variable analysis confirm this causal relationship. The effects are stronger for "opportunistic" (i.e., more informed) insider trades and when short sellers' attention is high. Return predictability of insider sales only occurs in stocks with high short-selling potential, suggesting that short sellers indirectly enhance the speed of information dissemination by accelerating trading by insiders. …

Remittances Without Borders, Tan Swee Liang, S. N. Venkataramanan, Anil Kishora Nov 2015

Remittances Without Borders, Tan Swee Liang, S. N. Venkataramanan, Anil Kishora

Research Collection School Of Economics

A Pan-Asian Mobile Remittance Platform might just be the next big disruption in global remittances. One out of every 28 people lives in a country that they were not born in. As migrants, they are estimated by The World Bank to send home US$636 billion in 2017, with three-quarters remitted to developing countries. These remittances form a significant percentage of the Gross Domestic Product (GDP) of many of these developing countries. Given their magnitude and contribution to national economies, even a small reduction in remittance cost adds billions to these local economies. Mobile-to-mobile cross border remittances have recently shown that …

Panel Data Models With Interactive Fixed Effects And Multiple Structural Breaks, Degui Li, Junhui Qian, Liangjun Su Nov 2015

Panel Data Models With Interactive Fixed Effects And Multiple Structural Breaks, Degui Li, Junhui Qian, Liangjun Su

Research Collection School Of Economics

In this paper we consider estimation of common structural breaks in panel data models with unobservable interactive fixed effects. We introduce a penalized principal component (PPC) estimation procedure with an adaptive group fused LASSO to detect the multiple structural breaks in the models. Under some mild conditions, we show that with probability approaching one the proposed method can correctly determine the unknown number of breaks and consistently estimate the common break dates. Furthermore, we estimate the regression coefficients through the post-LASSO method and establish the asymptotic distribution theory for the resulting estimators. The developed methodology and theory are applicable to …

Cointegration Of Matched Home Purchases And Rental Price Indexes: Evidence From Singapore, Badi H. Baltagi, Jing Li Nov 2015

Cointegration Of Matched Home Purchases And Rental Price Indexes: Evidence From Singapore, Badi H. Baltagi, Jing Li

Research Collection School Of Economics

This paper exploits the homogeneity feature of the Singapore private residential condominium market and constructs matched home purchase price and rental price series using the repeated sales method. These matched series allow us to conduct time series analysis to examine the long-term present value relationship in the housing market. Three key findings are obtained. First, we fail to establish a cointegrating relationship between the home purchase price and rental price based on nationally estimated indexes. Second, area-specific indexes demonstrate strong cross-correlations, invalidating the use of first generation panel unit root tests that ignore these cross-correlations. Third, Pesaran's CIPS test indicates …

What's Hot In Software Engineering Twitter Space?, Abhishek Sharma, Tian Yuan, David Lo

Research Collection School Of Computing and Information Systems

Twitter is a popular means to disseminate information and currently more than 300 million people are using it actively. Software engineers are no exception; Singer et al. have shown that many developers use Twitter to stay current with recent technological trends. At various time points, many users are posting microblogs (i.e., tweets) about the same topic in Twitter. We refer to this reasonably large set of topically-coherent microblogs in the Twitter space made at a particular point in time as an event. In this work, we perform an exploratory study on software engineering related events in Twitter. We collect a …
