A One Health Message About Bats Increases Intentions To Follow Public Health Guidance On Bat Rabies, Hang Lu, Katherine A. Mccomas, Danielle E. Buttke, Sungjong Roh, Margaret A. Wild May 2016

A One Health Message About Bats Increases Intentions To Follow Public Health Guidance On Bat Rabies, Hang Lu, Katherine A. Mccomas, Danielle E. Buttke, Sungjong Roh, Margaret A. Wild

Research Collection Lee Kong Chian School Of Business

Since 1960, bat rabies variants have become the greatest source of human rabies deaths in the United States. Improving rabies awareness and preventing human exposure to rabid bats remains a national public health priority today. Concurrently, conservation of bats and the ecosystem benefits they provide is of increasing importance due to declining populations of many bat species. This study used a visitor-intercept experiment (N = 521) in two U.S. national parks where human and bat interactions occur on an occasional basis to examine the relative persuasiveness of four messages differing in the provision of benefit and uncertainty information on intentions …

Competition And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu May 2016

Competition And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade for China over the period of 1995-2004, which was when China's openness drastically improved. We decompose gains from trade in two ways. First, we disentangle pro-competitive effects from a traditional Ricardian effect. Second, we separate the effect due to tariff reductions from that due to reductions in non-tariff trade costs. Our quantitative analysis shows that the pro-competitive effects account for 25.4% of the total welfare gains from trade, whereas the allocative effciency alone accounts for 22.3%. We also find that tariff reductions account for about 31.6% of reductions of overall …

A Characterization Of Single‐Peaked Preferences Via Random Social Choice Functions, Shurojit Chatterji, Arunava Sen, Huaxia Zeng May 2016

A Characterization Of Single‐Peaked Preferences Via Random Social Choice Functions, Shurojit Chatterji, Arunava Sen, Huaxia Zeng

Research Collection School Of Economics

This paper proves the following result: every path-connected domain of preferences that admits a strategy-proof, unanimous, tops-only random social choice function satisfying a compromise property is single-peaked. Conversely, every single-peaked domain admits a random social choice function satisfying these properties. Single-peakedness is defined with respect to arbitrary trees. The paper provides a justification of the salience of single-peaked preferences and evidence in favor of the Gul conjecture (Barber\303\240 2010).

Energy Price Shocks And External Balances, Bao Tan Huynh May 2016

Energy Price Shocks And External Balances, Bao Tan Huynh

Research Collection School Of Economics

This paper studies the impact of a wide set of energy price shocks on exter- nal balances using a two-country framework comprising multiple sectors and en- dogenous energy production with convex costs. The paper disentangles different demand and supply shocks in the energy market through their distinct impact on external balances. It provides a theoretical confirmation of Kilian et al. (2009) and a theoretical foundation to the determining role of the non-energy trade balance in the transmission of energy price shocks. The presence of durables also highlights the immediate channel through which energy prices impact the non-energy trade balance.

The Regret Elements Scale: Distinguishing The Emotional And Cognitive Components Of Regret, Joshua Buchanan, Amy Summerville, Jennifer Lehmann, Jochen Reb May 2016

The Regret Elements Scale: Distinguishing The Emotional And Cognitive Components Of Regret, Joshua Buchanan, Amy Summerville, Jennifer Lehmann, Jochen Reb

Research Collection Lee Kong Chian School Of Business

Regret is one of the most common emotions, but researchers generally measure it in an ad-hoc, unvalidated fashion. Three studies outline the construction and validation of the Regret Elements Scale (RES), which distinguishes between an affective component of regret, associated with maladaptive affective outcomes, and a cognitive component of regret, associated with functional preparatory outcomes. The present research demonstrates the RES’s relationship with distress (Study 1), appraisals of emotions (Study 2), and existing measures of regret (Study 3). We further demonstrate the RES’s ability to differentiate regret from other negative emotions (Study 2) and related traits (Study 3). The scale …

Sidestepping The Rock And The Hard Place: The Private Avoidance Of Prosocial Requests, Stephanie C. Lin, Rebecca L. Schaumberg, Taly Reich May 2016

Sidestepping The Rock And The Hard Place: The Private Avoidance Of Prosocial Requests, Stephanie C. Lin, Rebecca L. Schaumberg, Taly Reich

Research Collection Lee Kong Chian School Of Business

For some, facing a prosocial request feels like being trapped between a rock and a hard place, requiring either a resource (e.g., money) or psychological (e.g., self-reproach) cost. Because both outcomes are dissatisfying, we propose that these people are motivated to avoid prosocial requests, even when they face these requests in private, anonymous contexts. In two experiments, in which participants' anonymity and privacy was assured, participants avoided facing prosocial requests and were willing to do so at a personal cost. This was true both for people who would have otherwise complied with the request and those who would have otherwise …

Context-Aware Advertisement Recommendation For High-Speed Social News Feeding, Yuchen Li, Dongxiang Zhang, Ziquan Lan, Kian-Lee Tan May 2016

Context-Aware Advertisement Recommendation For High-Speed Social News Feeding, Yuchen Li, Dongxiang Zhang, Ziquan Lan, Kian-Lee Tan

Research Collection School Of Computing and Information Systems

Social media advertising is a multi-billion dollar market and has become the major revenue source for Facebook and Twitter. To deliver ads to potentially interested users, these social network platforms learn a prediction model for each user based on their personal interests. However, as user interests often evolve slowly, the user may end up receiving repetitive ads. In this paper, we propose a context-aware advertising framework that takes into account the relatively static personal interests as well as the dynamic news feed from friends to drive growth in the ad click-through rate. To meet the real-time requirement, we first propose …

Are You Charlie Or Ahmed? Cultural Pluralism In Charlie Hebdo Response On Twitter, Jisun An, Haewoon Kwak, Yelena Mejova, Sonia Alonso Saenz De Oger, Braulio Gomez Fortes May 2016

Are You Charlie Or Ahmed? Cultural Pluralism In Charlie Hebdo Response On Twitter, Jisun An, Haewoon Kwak, Yelena Mejova, Sonia Alonso Saenz De Oger, Braulio Gomez Fortes

Research Collection School Of Computing and Information Systems

We study the response to the Charlie Hebdo shootings of January 7, 2015 on Twitter across the globe. We ask whether the stances on the issue of freedom of speech can be modeled using established sociological theories, including Huntington’s culturalist Clash of Civilizations, and those taking into consideration social context, including Density and Interdependence theories. We find support for Huntington’s culturalist explanation, in that the established traditions and norms of one’s “civilization” predetermine some of one’s opinion. However, at an individual level, we also find social context to play a significant role, with non-Arabs living in Arab countries using #JeSuisAhmed …

#Greysanatomy Vs. #Yankees: Demographics And Hashtag Use On Twitter, Jisun An, Ingmar Weber May 2016

#Greysanatomy Vs. #Yankees: Demographics And Hashtag Use On Twitter, Jisun An, Ingmar Weber

Research Collection School Of Computing and Information Systems

Demographics, in particular, gender, age, and race, are a key predictor of human behavior. Despite the significant effect that demographics plays, most scientific studies using online social media do not consider this factor, mainly due to the lack of such information. In this work, we use state-of-the-art face analysis software to infer gender, age, and race from profile images of 350K Twitter users from New York. For the period from November 1, 2014 to October 31, 2015, we study which hashtags are used by different demographic groups. Though we find considerable overlap for the most popular hashtags, there are also …

Financial Health And Corporate Performance: A Comparison Of Manufacturing Companies In China And India, See Liang Foo, Shaakalya Pathak May 2016

Financial Health And Corporate Performance: A Comparison Of Manufacturing Companies In China And India, See Liang Foo, Shaakalya Pathak

Research Collection School Of Accountancy

The People’s Republic of China (China) and India are two leading economies in Asia Pacific. This study examines the relationship between the financial health, as measured by the Altman Z-Score, and corporate performance, as measured by the Return on Equity (ROE), of listed manufacturing companies in these two markets. A linear regression was conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a fourteen-year period are also analysed. The analysis covers the period from 2000 to 2013 (inclusive) and yielded a statistically positive correlation between ROE and the Z-Score for both …

Crowd-Sourced Text Analysis: Reproducible And Agile Production Of Political Data, Kenneth Benoit, Drew Conway, Benjamin E. Lauderdale, Michael Laver, Slava Mikhaylov May 2016

Crowd-Sourced Text Analysis: Reproducible And Agile Production Of Political Data, Kenneth Benoit, Drew Conway, Benjamin E. Lauderdale, Michael Laver, Slava Mikhaylov

Research Collection School of Social Sciences

Empirical social science often relies on data that are not observed in the field, but are transformed into quantitative variables by expert researchers who analyze and interpret qualitative raw sources. While generally considered the most valid way to produce data, this expert-driven process is inherently difficult to replicate or to assess on grounds of reliability. Using crowd-sourcing to distribute text for reading and interpretation by massive numbers of nonexperts, we generate results comparable to those using experts to read and interpret the same texts, but do so far more quickly and flexibly. Crucially, the data we collect can be reproduced …

Disparate Bilingual Experiences Modulate Task-Switching Advantages: A Diffusion-Model Analysis Of The Effects Of Interactional Context On Switch Costs, Andree Hartanto, Hwajin Yang May 2016

Disparate Bilingual Experiences Modulate Task-Switching Advantages: A Diffusion-Model Analysis Of The Effects Of Interactional Context On Switch Costs, Andree Hartanto, Hwajin Yang

Research Collection School of Social Sciences

Drawing on the adaptive control hypothesis (Green & Abutalebi, 2013), we investigated whether bilinguals' disparate interactional contexts modulate task-switching performance. Seventy-five bilinguals within the single-language context (SLC) and 58 bilinguals within the dual-language context (DLC) were compared in a typical task-switching paradigm. Given that DLC bilinguals switch between languages within the same context, while SLC bilinguals speak only one language in one environment and therefore rarely switch languages, we hypothesized that the two groups' stark difference in their interactional contexts of conversational exchanges would lead to differences in switch costs. As predicted, DLC bilinguals showed smaller switch costs than SLC …

China’S “Asia Dream”: The Belt Road Initiative And The New Regional Order, William A. Callahan May 2016

China’S “Asia Dream”: The Belt Road Initiative And The New Regional Order, William A. Callahan

Research Collection School of Social Sciences

Since Xi Jinping became leader in 2012, he has redirected Chinese foreign policy. This article examines the role of peripheral diplomacy in Xi’s emerging grand strategy. While it is popular to look to theories of the international system – offensive realism and liberal institutionalism – to explore this issue, this article follows constructivism to take seriously the role of ideas and domestic politics in foreign policy-making. Through an analysis of official and unofficial sources, it traces linkages between ideas, institutions, and behavior in Chinese foreign policy. In particular, it argues that Beijing is combining new ideas (China Dream, Asia Dream), …

Knowledge Cluster Development Through Connectivity: Examples From Southeast Asia, Hans-Dieter Evers, Thomas Menkhoff Apr 2016

Knowledge Cluster Development Through Connectivity: Examples From Southeast Asia, Hans-Dieter Evers, Thomas Menkhoff

Research Collection School Of Computing and Information Systems

Whereas since the 1990s national and regional planners saw the creation of knowledge clusters as a panacea for gaining a competitive advantage to propel a region or country into a higher stage of industrial development, recent research suggests that connectivity (e.g. through broadband penetration or joint research connections with collaborators elsewhere) is one of the enablers for socio-economic development. This paper will draw on the results of studies on knowledge clusters in Southeast Asian countries (Malaysia, Brunei, Singapore) as well as the relevant current literature to ask the question, whether knowledge clusters really contribute to regional development and if yes, …

Ontology-Aided Feature Correlation For Multi-Modal Urban Sensing, Archan Misra, Zaman Lantra, Kasthuri Jayarajah Apr 2016

Ontology-Aided Feature Correlation For Multi-Modal Urban Sensing, Archan Misra, Zaman Lantra, Kasthuri Jayarajah

Research Collection School Of Computing and Information Systems

The paper explores the use of correlation across features extracted from different sensing channels to help in urban situational understanding. We use real-world datasets to show how such correlation can improve the accuracy of detection of city-wide events by combining metadata analysis with image analysis of Instagram content. We demonstrate this through a case study on the Singapore Haze. We show that simple ontological relationships and reasoning can significantly help in automating such correlation-based understanding of transient urban events.

Patrol Scheduling In An Urban Rail Network, Hoong Chuin Lau, Zhi Yuan, Aldy Gunawan Apr 2016

Patrol Scheduling In An Urban Rail Network, Hoong Chuin Lau, Zhi Yuan, Aldy Gunawan

Research Collection School Of Computing and Information Systems

This paper presents the problem of scheduling security teams to patrol a mass rapid transit rail network of a large urban city. The main objective of patrol scheduling is to deploy security teams to stations of the network at varying time periods subject to rostering as well as security-related constraints. We present several mathematical programming models for different variants of this problem. To generate randomized schedules on a regular basis, we propose injecting randomness by varying the start time and break time for each team as well as varying the visit frequency and visit time for each station according to …

Pathways To Meet Critical Success Factors For Local Ppps: The Cases Of Urban Transport Infrastructure In Korean Cities, Yooil Bae, Yu-Min Joo Apr 2016

Pathways To Meet Critical Success Factors For Local Ppps: The Cases Of Urban Transport Infrastructure In Korean Cities, Yooil Bae, Yu-Min Joo

Research Collection School of Social Sciences

Public-Private Partnerships (PPPs) have been utilized extensively in both developed and developing countries to provide various public services and infrastructure. The literature points to many common critical success factors, including a mature financial market, transparent regulatory framework, advanced technology, and people's acceptance of new forms, but those can vary from country to country. South Korea's mature market capitalist system and strong regulatory framework have led to somewhat successful infrastructure provision through PPPs at the national level, but as our two cases of urban transportation in the Seoul Metropolitan Area indicate, local-level PPPs have demonstrated mixed results. By elaborating on the …

Bringing The Economy Back In: Hannah Arendt, Karl Marx, And The Politics Of Capitalism, Onur Ulas Ince Apr 2016

Bringing The Economy Back In: Hannah Arendt, Karl Marx, And The Politics Of Capitalism, Onur Ulas Ince

Research Collection School of Social Sciences

This article engages with the question of how to construct modern economic relations as an object of political theorizing by placing Hannah Arendt's and Karl Marx's writings in critical conversation. I contend that the political aspect of capitalism comes into sharpest relief less in relations of economic exploitation than in moments of expropriation that produce and reproduce the conditions of capitalist accumulation. To develop a theoretical handle on expropriation and thereby on the politics of capitalism, I syncretically draw on Marxian and Arendtian concepts by first examining expropriation through the Marxian analytic of "primitive accumulation of capital" and second delineating …

Laughter is a nonverbal vocal expression that often communicates positive affect and cooperative intent in humans. Temporally coincident laughter occurring within groups is a potentially rich cue of affiliation to overhearers. We examined listeners' judgments of affiliation based on brief, decontextualized instances of colaughter between either established friends or recently acquainted strangers. In a sample of 966 participants from 24 societies, people reliably distinguished friends from strangers with an accuracy of 53-67%. Acoustic analyses of the individual laughter segments revealed that, across cultures, listeners' judgments were consistently predicted by voicing dynamics, suggesting perceptual sensitivity to emotionally triggered spontaneous production. Colaughter …

Understanding The Failure Of China’S Specialized Cooperatives In China, Zhanping Hu, Qian Forrest Zhang, John A. Donaldson Apr 2016

Understanding The Failure Of China’S Specialized Cooperatives In China, Zhanping Hu, Qian Forrest Zhang, John A. Donaldson

Research Collection School of Social Sciences

At first blush, contemporary China seems ripe for the rapid development of agricultural cooperatives. After all, cooperatives have not only enjoyed a long history in China, but the country’s recent experience with agricultural communes should make it more amenable to the reestablishment of joint production and spontaneous bottom-up cooperation. Agricultural cooperatives in China date to the 1930s, as Rural Reconstruction Movement advocates promoted cooperatives as a “third road” between capitalism and socialism. Although Mao’s regime disbanded most bottom-up cooperatives, rural cooperatives began to reemerge in rural China by the end of the 20th century, particularly after 1998, when farmer cooperatives …

Refining The Prize: Chinese Oil Refineries And Its Energy Security, Inwook Kim Apr 2016

Refining The Prize: Chinese Oil Refineries And Its Energy Security, Inwook Kim

Research Collection School of Social Sciences

Since China became a net oil importer in 1993, oil refineries have played integral roles in China's quest for oil security. And yet, the capacity, security, and configurations of refineries were rarely featured in the discussions about China's oil policy. To fill this gap, this paper explains the basics of refinery economics and technology, and details the development in China's refining industry since the early 1990s. By taking refineries into consideration, it then revisits and reassesses the existing literature regarding the motives and drivers behind China's foreign oil policy, its effectiveness, and the political interactions between China and crude oil …
