Counting Members In My League: Mate Value Moderates Economic Effects Of Local Operational Sex Ratio, Zilin Yan Nov 2018

Counting Members In My League: Mate Value Moderates Economic Effects Of Local Operational Sex Ratio, Zilin Yan

Dissertations and Theses Collection (Open Access)

When local operational sex ratio skews toward a larger proportion of same-sex to opposite-sex individuals, should members of the surplus sex increase or decrease (economic) efforts on reproduction? Past research yielded mixed results. In light of the fact that modern humans are highly mobile and can relocate to communities that may offer better reproductive prospects, it may not always be a given that individuals facing same-sex skewed local community will become current-oriented with regard to reproduction; instead, they may contemplate whether their efforts will pay off and decide whether they prefer to wait for better situations later. The present research …

Linky: Visualizing User Identity Linkage Results For Multiple Online Social Networks (Demo), Roy Ka-Wei Lee, Ming Shan Hee, Philips Kokoh Prasetyo, Ee-Peng Lim Nov 2018

Linky: Visualizing User Identity Linkage Results For Multiple Online Social Networks (Demo), Roy Ka-Wei Lee, Ming Shan Hee, Philips Kokoh Prasetyo, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

User identity linkage across online social networks is an emerging research topic that has attracted attention in recent years. Many user identity linkage methods have been proposed so far and most of them utilize user profile, content and network information to determine if two social media accounts belong to the same person. In most cases, user identity linkage methods are evaluated by performing some prediction tasks with the results presented using some overall accuracy measures. However, the methods are rarely compared at the individual user level where a predicted matched (or linked) pair of user identities from different online social …

Improving Multi-Label Emotion Classification Via Sentiment Classification With Dual Attention Transfer Network, Jianfei Yu, Luis Marujo, Jing Jiang, Pradeep Karuturi, William Brendel Nov 2018

Improving Multi-Label Emotion Classification Via Sentiment Classification With Dual Attention Transfer Network, Jianfei Yu, Luis Marujo, Jing Jiang, Pradeep Karuturi, William Brendel

Research Collection School Of Computing and Information Systems

In this paper, we target at improving the performance of multi-label emotion classification with the help of sentiment classification. Specifically, we propose a new transfer learning architecture to divide the sentence representation into two different feature spaces, which are expected to respectively capture the general sentiment words and the other important emotion-specific words via a dual attention mechanism. Extensive experimental results demonstrate that our transfer learning approach can outperform several strong baselines and achieve the state-of-the-art performance on two benchmark datasets.

With the advent of social media, developers are increasingly using it in their software development activities. Twitter is one of the popular social mediums used by developers. A recent study by Singer et al. found that software developers use Twitter to “keep up with the fast-paced development landscape.” Unfortunately, due to the general-purpose nature of Twitter, it’s challenging for developers to use Twitter for their development activities. Our survey with 36 developers who use Twitter in their development activities highlights that developers are interested in following specialized software gurus who share relevant technical tweets.To help developers perform this task, in …

Centroid-Amenities: An Interactive Visual Analytical Tool For Exploring And Analyzing Amenities In Singapore, Xue Qian Jazreel Siew, Sean Jia Ming Koh Nov 2018

Centroid-Amenities: An Interactive Visual Analytical Tool For Exploring And Analyzing Amenities In Singapore, Xue Qian Jazreel Siew, Sean Jia Ming Koh

Research Collection School Of Computing and Information Systems

Planning for civic amenities in a fast-changing urban setting such as Singapore is never an easy task. And as urban planners look toward more data-driven approaches toward urban planning, so grows the demand for more flexible geospatial analytics tools to facilitate a more iterative and granular approach toward urban planning. Such specific tools however, are not always readily available as plugins for traditional desktop GIS software, as numerous customizations must be made to model specific temporal planning scenarios for quick analysis, which could prove both costly and time-consuming. Hence, to address this need, open-source tools such as R Shiny could …

Has Patronage Lost Its Punch In Malaysia?, Sebastian Carl Dettman, Meredith L. Weiss Nov 2018

Has Patronage Lost Its Punch In Malaysia?, Sebastian Carl Dettman, Meredith L. Weiss

Research Collection School of Social Sciences

The personalistic linkages that generally define Malaysian politics come into sharp relief when candidates confront the imperative of winning office. Malaysia’s 14th general election (GE14), as other previous iterations, saw politicians emphasize their ‘personal touch’ and offer a barrage of targeted promises. Yet these relationships are not confined to elections and reflect deep connections between voters and politicians – not only for politicians in the long-dominant Barisan Nasional coalition, but also for the newly victorious Pakatan Harapan parties. The authors of this article draw on original survey data to show the embeddedness of these relationships beyond elections. In GE14, the …

Partisan Conflict And Stock Price, Dashan Huang, Wang Liyao Nov 2018

Partisan Conflict And Stock Price, Dashan Huang, Wang Liyao

Research Collection Lee Kong Chian School Of Business

Partisan conflict has been one dominant theme in U.S. politics in recent years. By using the textual index of Azzimonti (2018), this paper shows that partisan conflict positively predicts market returns, controlling for economic predictors and proxies for uncertainty, disagreement, geopolitical risk, and political sentiment. A one standard-deviation increase in partisan conflict is associated with a 0.58% increase in next month market return. The forecasting power concentrates in periods when the president is from the Republican Party or the majority of House is Republicans. Partisan conflict is positively related to downside risk, and makes investors more conservative when its value …

Bilingualism Confers Advantages In Task Switching: Evidence From The Dimensional Change Card Sort Task, Hwajin Yang, Andree Hartanto, Sujin Yang Nov 2018

Bilingualism Confers Advantages In Task Switching: Evidence From The Dimensional Change Card Sort Task, Hwajin Yang, Andree Hartanto, Sujin Yang

Research Collection School of Social Sciences

We examined the influence of bilingualism on task switching by inspecting various markers for task-switching costs. English monolinguals and Korean–English bilinguals completed a modified Dimensional Change Card Sort task based on a nonverbal task-switching paradigm. We found advantages for Korean–English bilinguals in terms of smaller single-task (pure-block) switch costs and greater reactivation benefits than those of English monolinguals. However, bilingual advantages in mixing costs were relatively weak, and the two groups did not differ on local switch costs. Notably, when we approximated the cue-based priming effect in single-task (pure) blocks, we found no evidence that the locus of bilingual advantages …

Effects Of Cultural Tightness-Looseness And Social Network Density On Expression Of Positive And Negative Emotions: A Large-Scale Study Of Impression Management By Facebook Users, Pan Liu, David Chan, Lin Qiu, William Tov, Victor Joo Chuan Tong Nov 2018

Effects Of Cultural Tightness-Looseness And Social Network Density On Expression Of Positive And Negative Emotions: A Large-Scale Study Of Impression Management By Facebook Users, Pan Liu, David Chan, Lin Qiu, William Tov, Victor Joo Chuan Tong

Research Collection School of Social Sciences

Using data from 13,789 Facebook users across U.S. states, this study examined the main effects of societal-level cultural tightness–looseness and its interaction effects with individuals’ social network density on impression management (IM) in terms of online emotional expression. Results showed that individuals from culturally tight (vs. loose) states were more likely to express positive emotions and less likely to express negative emotions. Meanwhile, for positive emotional expression, there was a tightness–looseness by social network density interaction effect. In culturally tight states, individuals with dense (vs. sparse) networks were more likely to express positive emotions, while in culturally loose states this …

In a commentary, SMU Associate Professor of Law Eugene Tan said the choice of Finance Minister Heng Swee Keat as the People’s Action Party’s first assistant secretary-general should not come as a surprise as he was the only fourth-generation (4G) leader to be made a full Minister upon winning his maiden election in 2011, helming the Education Ministry between 2011 and 2015. He opined that Mr Heng’s 4G team will have to stamp their distinctive collective identity and leadership ethos as governance becomes increasingly complex.

Whole-Of-Society Approach Needed Against Truth Decay, Tan K. B. Eugene Nov 2018

Whole-Of-Society Approach Needed Against Truth Decay, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan opined that technology has compounded the problem of fake news and that governments and legislation are not the only means to curb them. This is especially so when blunt legislation may end up eroding the fundamental liberty of freedom of speech and expression. He sought the use of a multi-pronged, multi-stakeholder approach against disinformation campaigns and with trusted sources of information being boosted to produce real information for the public.

Premature Service Of Payment Claims Under The Building And Construction Industry Security Of Payment Act: Audi Construction Pte Ltd V Kian Hiap Construction Pte Ltd, Benjamin Joshua Ong Nov 2018

Premature Service Of Payment Claims Under The Building And Construction Industry Security Of Payment Act: Audi Construction Pte Ltd V Kian Hiap Construction Pte Ltd, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

In Audi Construction Pte Ltd v Kian Hiap Construction Pte Ltd, the Singapore Court of Appeal considereda payment claim to have been validly served although it was served earlier thanthe contractually stipulated date. This was because the service of the paymentclaim was “effective” only from the contractually stipulated date, and theclaimant had had a “good reason” to serve the payment claim early. This notecritically examines the reasoning in Audi vis-à-vis the existing law, the principleof freedom of contract, and the intentions of the parties in that case. In theabsence of future judicial elaboration on the “effective service” and “goodreason” doctrines, …

Revisiting The Foundations Of Dominant-Strategy Mechanisms, Yi-Chun Chen, Jiangtao Li Nov 2018

Revisiting The Foundations Of Dominant-Strategy Mechanisms, Yi-Chun Chen, Jiangtao Li

Research Collection School Of Economics

An important question in mechanism design is whether there is any theoretical foundation for the use of dominant-strategy mechanisms. This paper studies the maxmin and Bayesian foundations of dominant-strategy mechanisms in general social choice environments with quasi-linear preferences and private values. We propose a condition called the uniform shortest-path tree that, under regularity, ensures the foundations of dominant-strategy mechanisms. This exposes the underlying logic of the existence of such foundations in the single-unit auction setting, and extends the argument to cases where it was hitherto unknown. To prove this result, we adopt the linear programming approach to mechanism design. In …

The Grid Bootstrap For Continuous Time Models, Yiu Lim Lui, Weilin Xiao, Jun Yu Nov 2018

The Grid Bootstrap For Continuous Time Models, Yiu Lim Lui, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper considers the grid bootstrap for constructing confidence intervals for the persistence parameter in a class of continuous time models driven by a Levy process. Its asymptotic validity is established by assuming the sampling interval (h) shrinks to zero. Its improvement over the in-fill asymptotic theory is achieved by expanding the coefficient-based statistic around its in fill asymptotic distribution which is non-pivotal and depends on the initial condition. Monte Carlo studies show that the gird bootstrap method performs better than the in-fill asymptotic theory and much better than the long-span theory. Empirical applications to U.S. interest rate data highlight …

Potential Crime Risk And Housing Market Responses, Seonghoon Kim, Kwan Ok Lee Nov 2018

Potential Crime Risk And Housing Market Responses, Seonghoon Kim, Kwan Ok Lee

Research Collection School Of Economics

We study how information on local (dis)amenities is transmitted and manifested in housing markets. Using nationwide data on multifamily homes in South Korea, we analyze heterogeneity in the effect of a sex offender's presence on sale prices and rents of nearby homes. Our results demonstrate that the price effect of the offender's move-in varies significantly by spatial context. People react more strongly and persistently to the move-in of the offender in places wherein indicators of social connectedness are stronger, such as places with relatively low population density. We also find that, unlike housing prices, rents do not change in response …

Identifying Latent Grouped Patterns In Cointegrated Panels, Wenxin Huang, Sainan Jin, Liangjun Su Nov 2018

Identifying Latent Grouped Patterns In Cointegrated Panels, Wenxin Huang, Sainan Jin, Liangjun Su

Research Collection School Of Economics

We consider a panel cointegration model with latent group structures that allows for heterogeneous long-run relationships across groups. We extend Su, Shi, and Phillips’ (2016) classifier-Lasso (C-Lasso) method to the nonstationary panels and allow for the presence of endogeneity in both the stationary and nonstationary regressors in the model. In addition, we allow the dimension of the stationary regressors to diverge with the sample size. We show that we can identify the individuals’ group membership and estimate the group-specific long-run cointegrated relationships simultaneously. We demonstrate the desirable property of uniform classification consistency and the oracle properties of both the C-Lasso …

Change Detection And The Causal Impact Of The Yield Curve, Shuping Shi, Peter C. B. Phillips, Stan Hurn Nov 2018

Change Detection And The Causal Impact Of The Yield Curve, Shuping Shi, Peter C. B. Phillips, Stan Hurn

Research Collection School Of Economics

Causal relationships in econometrics are typically based on the concept of predictability and are established by testing Granger causality. Such relationships are susceptible to change, especially during times of financial turbulence, making the real-time detection of instability an important practical issue. This article develops a test for detecting changes in causal relationships based on a recursive evolving window, which is analogous to a procedure used in recent work on financial bubble detection. The limiting distribution of the test takes a simple form under the null hypothesis and is easy to implement in conditions of homoskedasticity and conditional heteroskedasticity of an …

Threshold Regression Asymptotics: From The Compound Poisson Process To Two-Sided Brownian Motion, Ping Yu, Peter C. B. Phillips Nov 2018

Threshold Regression Asymptotics: From The Compound Poisson Process To Two-Sided Brownian Motion, Ping Yu, Peter C. B. Phillips

Research Collection School Of Economics

The asymptotic distribution of the least squares estimator in threshold regression is expressed in terms of a compound Poisson process when the threshold effect is fixed and as a functional of two-sided Brownian motion when the threshold effect shrinks to zero. This paper explains the relationship between this dual limit theory by showing how the asymptotic forms are linked in terms of joint and sequential limits. In one case, joint asymptotics apply when both the sample size diverges and the threshold effect shrinks to zero, whereas sequential asymptotics operate in the other case in which the sample size diverges first …

Labour Research Conference 2018: Upskilling Of Mature Workers, Stephen Hoskins, Luca Facchinello

Research Collection School Of Economics

Many developed countries are approaching an era of ageing population due to an increase in longevity and decrease in fertility rates. Singapore is no exception, having one of the fastest ageing populations in Asia, which is driven by low fertility rates and the third longest life expectancy in the world. The number of elderly citizens, defined as those aged 65 and above, is expected to triple to 900,000 by 2030, making up about 28% of the total population in Singapore (Population SG, 2016). This changing population age profile, combined with a competitive labour market, means it makes business sense to …

The Impact Of In-House Unnatural Death On Property Values: Evidence From Hong Kong, Zheng Chang, Jing Li Nov 2018

The Impact Of In-House Unnatural Death On Property Values: Evidence From Hong Kong, Zheng Chang, Jing Li

Research Collection School Of Economics

The occurrence of in-house unnatural death could negatively affect the value of housing property. This study evaluates the geographic and temporal scope of the impact of unnatural death on property values in Hong Kong. By exploiting the spatial and intertemporal variation of the shock in a difference-in-differences approach, we find significant negative externalities of unnatural death incidence on neighborhood housing values. On average, units in which an unnatural death occurred experience a 25% drop in value following the death. Nearby units on the same floor also show a significant price drop of 4.5%. Prices of units on other floors of …

Low Power Individuals In Social Power Research: A Quantitative Review, Theoretical Framework, And Empirical Test, Michael Schaerer, Christilene Du Plessis, Andy J. Yap, Stefan Thau Nov 2018

Low Power Individuals In Social Power Research: A Quantitative Review, Theoretical Framework, And Empirical Test, Michael Schaerer, Christilene Du Plessis, Andy J. Yap, Stefan Thau

Research Collection Lee Kong Chian School Of Business

We examine the role of low-power individuals in social power research. A multi-method literature review reveals that low-power individuals may be insufficiently understood because many studies lack necessary control conditions that allow drawing inferences about low power, effects are predominantly attributed to high power, and qualitative reviews primarily focus on how high-power individuals feel, think, and behave. Challenging the assumption that low power tends to produce opposite consequences of high power, we highlight several similarities between the two states. Based on social exchange theories, we propose that unequal-power (vs. equal-power) relationships make instrumental goals, competitive attitudes, and exchange rules salient, …
