Power Motivates Interpersonal Connection Following Social Exclusion, Jayanth Narayanan, Kenneth Tai, Zoe Kinias Nov 2013

Power Motivates Interpersonal Connection Following Social Exclusion, Jayanth Narayanan, Kenneth Tai, Zoe Kinias

Research Collection Lee Kong Chian School Of Business

Research has systematically documented the negative effects of social exclusion, yet little is known about how these negative effects can be mitigated. Building on the approach-inhibition theory of power (Keltner, Gruenfeld, & Anderson, 2003), we examined the role of power in facilitating social connection following exclusion. Four experiments found that following exclusion, high power (relative to low power) individuals intend to socially connect more with others. Specifically, following exclusion, individuals primed with high power sought new social connections more than those primed with low power (Studies 1–4) or those receiving no power prime (Study 1). The intention to seek social …

What You Want Is Not What You Get: Predicting Sharing Policies For Text-Based Content On Facebook, Arunesh Sinha, Li Yan, Lujo Bauer Nov 2013

What You Want Is Not What You Get: Predicting Sharing Policies For Text-Based Content On Facebook, Arunesh Sinha, Li Yan, Lujo Bauer

Research Collection Lee Kong Chian School Of Business

As the amount of content users publish on social networking sites rises, so do the danger and costs of inadvertently sharing content with an unintended audience. Studies repeatedly show that users frequently misconfigure their policies or misunderstand the privacy features offered by social networks. A way to mitigate these problems is to develop automated tools to assist users in correctly setting their policy. This paper explores the viability of one such approach: we examine the extent to which machine learning can be used to deduce users' sharing preferences for content posted on Facebook. To generate data on which to evaluate …

Autochthonous Constitutional Design In Post-Colonial Singapore: Intimations Of Confucianism And The Leviathan In Entrenching Dominant Government, Eugene K. B. Tan Nov 2013

Autochthonous Constitutional Design In Post-Colonial Singapore: Intimations Of Confucianism And The Leviathan In Entrenching Dominant Government, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

Does Singapore's approach to institutional design vis-avis political representation prioritize strong and effective government, or is the goal one that is geared towards a representative government as a means of enhancing political governance? his paper examines the series of amendments to Singapore's Constitution and related legislation, between 1984 and 1990, and in 2010, which relate to political representation in Singapore's electoral system and unicameral legislature. At one level, the changes are part of the endeavor to retain Parliament's standing as the focal point of Singapore's Westminstermodeled system of government. The constitutional changes reflect the political elites' abiding belief that institutional …

Estimation Of Time-Varying Adjusted Probability Of Informed Trading And Probability Of Symmetric Order-Flow Shock, Daniel Preve, Yiu Kuen Tse Nov 2013

Estimation Of Time-Varying Adjusted Probability Of Informed Trading And Probability Of Symmetric Order-Flow Shock, Daniel Preve, Yiu Kuen Tse

Research Collection School Of Economics

Recently Duarte and Young (2009) study the probability of informed trading (PIN) proposed by Easley et al. (2002) and decompose it into two parts: the adjusted PIN (APIN) as a measure of asymmetric information and the probability of symmetric order-flow shock (PSOS) as a measure of illiquidity. They provide some cross-section estimates of these measures using daily data over annual periods. In this paper we propose a method to estimate daily APIN and PSOS by extending the method in Tay et al. (2009) using high-frequency transaction data. Our empirical results show that while PIN is positively contemporaneously correlated with variance, …

Relook Link Between Low Wages And Foreign Workers, Hian Teck Hoon Nov 2013

Relook Link Between Low Wages And Foreign Workers, Hian Teck Hoon

Research Collection School Of Economics

He felt that the commonplace idea that the huge inflow of foreign workers in the past decade caused a stagnation and even decline in real wage earnings of Singaporean workers in the bottom half of the income distribution was flawed. He argued that real wage earnings of the median worker actually increased when the number of inflows of foreign workers was reaching its peak. Prof Hoon thus felt that Singapore must now find a means to gear its political and economic institutions to continue to embrace economic openness in the next half-century, in order to be able to deliver good …

Egalitarian Division Under Leontief Preferences, Jin Li, Jingyi Xue Nov 2013

Egalitarian Division Under Leontief Preferences, Jin Li, Jingyi Xue

Research Collection School Of Economics

We consider the problem of fairly dividing l divisible goods among n agents with the generalized Leontief preferences. We propose and characterize the class of generalized egalitarian rules which satisfy efficiency, group strategy-proofness, anonymity, resource monotonicity, population monotonicity, envy-freeness and consistency. On the Leontief domain, our rules generalize the egalitarian-equivalent rules with reference bundles. We also extend our rules to agent-specific and endowment-specific egalitarian rules. The former is a larger class of rules satisfying all the previous properties except anonymity and envy-freeness. The latter is a class of efficient, group strategy-proof, anonymous and individually rational rules when the resources are …

An Epidemiological Approach To Opinion And Price-Volume Dynamics, Dong Hong, Harrison G. Hong, Andrei Ungureanu Nov 2013

An Epidemiological Approach To Opinion And Price-Volume Dynamics, Dong Hong, Harrison G. Hong, Andrei Ungureanu

Research Collection Lee Kong Chian School Of Business

We develop a simple and tractable model of opinions and price-volume dynamics based on a word-of-mouth communication process widely used in epidemiology. Risk-averse investors have different opinions depending on whether they heard the news from a friend. Opinions initially diverge and then converge over time as news spreads, which leads to price adjustment and trading volume. News released to many leads to an expected difusion rate (the change in the fraction of investors with the news) that declines with time. But news initially released to few leads to an expected diffusion rate that initially increases in time and only then …

From Coercion To Politics To Law: The Evolution Of Property Rights Protection, Fali Huang Nov 2013

From Coercion To Politics To Law: The Evolution Of Property Rights Protection, Fali Huang

Research Collection School Of Economics

This paper shows how property rights security improves over time as a result of increasing legal quality and political democratization in a political economy context, where political and legal institutions adapt to evolving factor composition of land and capital in the dynamic economic development process. There seems to exist a clear sequence of di⁄erent forms of protection in that it is unlikely to have a strong rule of law with an exploitative political regime, or to have a democratic political system when the distribution of potential coercive power is too skewed. The routine form of protection thus shifts from coercion …

Limit Theory For An Explosive Autoregressive Process, Xiaohu Wang, Jun Yu Nov 2013

Limit Theory For An Explosive Autoregressive Process, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

Large sample properties are studied for a first-order autoregression (AR(1)) with a root greater than unity. It is shown that, contrary to the AR coefficient, the least-squares (LS) estimator of the intercept and its t-statistic are asymptotically normal without requiring the Gaussian error distribution, and hence an invariance principle applies. The coefficient based test and the t test have better power for testing the hypothesis of zero intercept in the explosive process than in the stationary process.

Social Sensing For Urban Crisis Management: The Case Of Singapore Haze, Philips Kokoh Prasetyo, Ming Gao, Ee Peng Lim, Christie N. Scollon Nov 2013

Social Sensing For Urban Crisis Management: The Case Of Singapore Haze, Philips Kokoh Prasetyo, Ming Gao, Ee Peng Lim, Christie N. Scollon

Research Collection School Of Computing and Information Systems

Sensing social media for trends and events has become possible as increasing number of users rely on social media to share information. In the event of a major disaster or social event, one can therefore study the event quickly by gathering and analyzing social media data. One can also design appropriate responses such as allocating resources to the affected areas, sharing event related information, and managing public anxiety. Past research on social event studies using social media often focused on one type of data analysis (e.g., hashtag clusters, diffusion of events, influential users, etc.) on a single social media data …

Information Vs Interaction: An Alternative User Ranking Model For Social Networks, Wei Xie, Ai Phuong Hoang, Feida Zhu, Ee Peng Lim Nov 2013

Information Vs Interaction: An Alternative User Ranking Model For Social Networks, Wei Xie, Ai Phuong Hoang, Feida Zhu, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The recent years have seen an unprecedented boom of social network services, such as Twitter, which boasts over 200 million users. In such big social platforms, the influential users are ideal targets for viral marketing to potentially reach an audience of maximal size. Most proposed algorithms rely on the linkage structure of the respective underlying network to determine the information flow and hence indicate a users influence. From social interaction perspective, we built a model based on the dynamic user interactions constantly taking place on top of these linkage structures. In particular, in the Twitter setting we supposed a principle …

Predicting Best Answerers For New Questions: An Approach Leveraging Topic Modeling And Collaborative Voting, Yuan Tian, Pavneet Singh Kochhar, Ee Peng Lim, Feida Zhu, David Lo Nov 2013

Predicting Best Answerers For New Questions: An Approach Leveraging Topic Modeling And Collaborative Voting, Yuan Tian, Pavneet Singh Kochhar, Ee Peng Lim, Feida Zhu, David Lo

Research Collection School Of Computing and Information Systems

Community Question Answering (CQA) sites are becoming increasingly important source of information where users can share knowledge on various topics. Although these platforms bring new opportunities for users to seek help or provide solutions, they also pose many challenges with the ever growing size of the community. The sheer number of questions posted everyday motivates the problem of routing questions to the appropriate users who can answer them. In this paper, we propose an approach to predict the best answerer for a new question on CQA site. Our approach considers both user interest and user expertise relevant to the topics …

Predicting User's Political Party Using Ideological Stances, Swapna Gottopati, Minghui Qiu, Liu Yang, Feida Zhu, Jing Jiang

Research Collection School Of Computing and Information Systems

Predicting users political party in social media has important impacts on many real world applications such as targeted advertising, recommendation and personalization. Several political research studies on it indicate that political parties’ ideological beliefs on sociopolitical issues may influence the users political leaning. In our work, we exploit users’ ideological stances on controversial issues to predict political party of online users. We propose a collaborative filtering approach to solve the data sparsity problem of users stances on ideological topics and apply clustering method to group the users with the same party. We evaluated several state-of-the-art methods for party prediction task …

Challenges And Opportunities In Taxi Fleet Anomaly Detection, Rijurekha Sen, Rajesh Krishna Balan Nov 2013

Challenges And Opportunities In Taxi Fleet Anomaly Detection, Rijurekha Sen, Rajesh Krishna Balan

Research Collection School Of Computing and Information Systems

To enhance fleet operation and management, logistics companies instrument their vehicles with GPS receivers and network connectivity to servers. Mobility traces from such large fleets provide significant information on commuter travel patterns, traffic congestion and road anomalies, and hence several researchers have mined such datasets to gain useful urban insights. These logistics companies, however, incur significant cost in deploying and maintaining their vast network of instrumented vehicles. Thus research problems, that are not only of interest to urban planners, but to the logistics companies themselves are important to attract and engage these companies for collaborative data analysis. In this paper, …

Libquest: A Problem Based Learning Approach To Information Literacy, Priyanka Sharma, Yuyun W. Ishak Oct 2013

Libquest: A Problem Based Learning Approach To Information Literacy, Priyanka Sharma, Yuyun W. Ishak

Research Collection Library

Problem Based Learning (PBL) appears to be the way forward. Gen Z students seem to prefer discovery and a self-paced learning environment (often using a variety of gadgets) rather than a more structured instruction module in a classroom setting. Kenney (2008) found that PBL provides the theoretical framework for a learner centered, active instructional experience that relies on collaboration, critical thinking and hands-on interaction with resources. Pelikan (2004) developed and delivered course-related library instruction using PBL over a period of two years in Penn State School of Information Sciences and Technology and concluded that PBL is a worth pursuing approach …

Stock Liquidity And The Pricing Of Earnings: A Comparison Of China’S Floating And Non-Floating Shares, Lou Fang, Jiwei Wang, Hongqi Yuan Oct 2013

Stock Liquidity And The Pricing Of Earnings: A Comparison Of China’S Floating And Non-Floating Shares, Lou Fang, Jiwei Wang, Hongqi Yuan

Research Collection School Of Accountancy

The reform to convert non-floating shares to floating in China provides a setting in which shares are subject to different liquidity constraint. We show that the severity of this constraint is inversely related to the extent to which earnings information is reflected in the share prices. Specifically, before the reform, the transfer prices of non-floating shares reflect much less earnings information than the market prices of floating shares. After the reform, however, both types of transfer reflect more earnings information, although the weights are still less than that found in the market prices. Thus, China's unique setting shows that share …

Evolving Chineseness, Ethnicity And Business: The Making Of The Ethnic Chinese As A ‘Market-Dominant Minority’ In Indonesia, Chang Yau Hoon Oct 2013

Evolving Chineseness, Ethnicity And Business: The Making Of The Ethnic Chinese As A ‘Market-Dominant Minority’ In Indonesia, Chang Yau Hoon

Research Collection School of Social Sciences

The ethnic Chinese in Indonesia play a very significant role in the nation’s economy. Their dominance in the Indonesian economy is often seen as disproportionate to their numbers, as reflected in the popular assertion that “the Chinese constitute only 3.5 percent of the population but control 70 percent of Indonesia’s economy”. In the New York Times bestseller, World on Fire: How Exporting Free Market Democracy Breeds Ethnic Hatred and Global Instability, Amy Chua (2004) identified Chinese Indonesians as one of the “ market-dominant minorities” in the world. Her book highlights the double bind of free market democracy: it privileges certain …

Multicultural Citizenship Education In Indonesia: The Case Of A Chinese Christian School, Chang Yau Hoon Oct 2013

Multicultural Citizenship Education In Indonesia: The Case Of A Chinese Christian School, Chang Yau Hoon

Research Collection School of Social Sciences

This study investigates how multicultural citizenship education is taught in a Chinese Christian school in Jakarta, where multiculturalism is not a natural experience. Schoolyard ethnographic research was deployed to explore the reality of a ‘double minority’ — Chinese Christians — and how the citizenship of this marginal group is constructed and contested in national, school, and familial discourses. The article argues that it is necessary for schools to actively implement multicultural citizenship education in order to create a new generation of young adults who are empowered, tolerant, active, participatory citizens of Indonesia. As schools are a microcosm of the nation-state, …

Balancing Spirituality And Secularism, Globalism And Nationalism: The Geographies Of Identity, Integration And Citizenship In Schools, Lily Kong

Research Collection School of Social Sciences

Geographies of education have drawn more research attention in the last decade. The varied motivations for geographical attention to education have led to divergent approaches. First, a macro, political economy or "outward looking" approach has examined educational provision and what it tells us about wider social, economic and political processes. Second, a micro, social-cultural or "inward looking" approach has emphasised social difference within school spaces, and the links between home and educational spaces. This latter approach has also acknowledged the importance of the voices of children and young people in understanding educational experiences. In this paper, l take stock of …
