Learning Latent Characteristics Of Locations Using Location-Based Social Networking Data, Thanh Nam Doan

Dissertations and Theses Collection (Open Access)

This dissertation addresses the modeling of latent characteristics of locations to describe the mobility of users of location-based social networking platforms. With many users signing up location-based social networking platforms to share their daily activities, these platforms become a gold mine for researchers to study human visitation behavior and location characteristics. Modeling such visitation behavior and location characteristics can benefit many use- ful applications such as urban planning and location-aware recommender sys- tems. In this dissertation, we focus on modeling two latent characteristics of locations, namely area attraction and neighborhood competition effects using location-based social network data. Our literature survey …

Response Distortion On Personality Tests In Applicants: Comparing High-Stakes To Low-Stakes Medical Settings, Jeromy Anglim, Stefan Bozic, Jonathon Little, Filip Lievens

Research Collection Lee Kong Chian School Of Business

The current study examined the degree to which applicants applying for medical internships distort their responses to personality tests and assessed whether this response distortion led to reduced predictive validity. The applicant sample (n = 530) completed the NEO Personality Inventory whilst applying for one of 60 positions as first-year post-graduate medical interns. Predictive validity was assessed using university grades, averaged over the entire medical degree. Applicant responses for the Big Five (i.e., neuroticism, extraversion, openness, conscientiousness, and agreeableness) and 30 facets of personality were compared to a range of normative samples where personality was measured in standard research settings …

Distinguishing Agent-Relativity From Agent Neutrality, Matthew Hammerton

Research Collection School of Social Sciences

The agent-relative/agent-neutral distinction is one of the most important incontemporary moral theory. Yet providing an adequate formal account of it hasproven to be difficult. In this article I defend a new formal account of the distinction,one that avoids various problems faced by other accounts. My account is based on aninfluential account of the distinction developed by McNaughton and Rawling. I arguethat their approach is on the right track but that it succumbs to two seriousobjections. I then show how to formulate a new account that follows the key insightsof McNaughton and Rawling’s approach yet avoids the two objections.

Singapore Income Taxation, Vincent Ooi, Irving Aw, Joanna Yap

Research Collection Yong Pung How School Of Law

28.1.1 Section 10(1) of the Income Tax Act (Cap. 134, 2014 Rev. Ed.) (“ITA”) is the charging provision which provides for income tax to be payable for each year of assessment (“YA”) upon the income of any person. Income is taxable if it falls within one of the enumerated heads of charge under sections 10(1)(a) to (g).Income is taxable only if it is sourced in Singapore, i.e. accruing in or derived from Singapore, or received in Singapore from outside Singapore, subject to variations.Only revenue (and not capital) receipts are taxable, and only revenue (and not capital) expenses are deductible for …

Advice Giving: A Subtle Pathway To Power, Michael Schaerer, Leigh Tost, Li Huang, Francesca Gino, Rick Larrick

Research Collection Lee Kong Chian School Of Business

We propose that interpersonal behaviors can activate feelings of power, and we examine this idea in the context of advice giving. Specifically, we show a) that advice giving is an interpersonal behavior that enhances individuals’ sense of power and b) that those who seek power are motivated to engage in advice giving. Four studies, including two experiments (n=290, n=188), an organization-based field study (n=94), and a negotiation simulation (n=124) demonstrate that giving advice enhances the advisor’s sense of power because it gives the advisor perceived influence over others’ actions. Two of our studies further demonstrate that people with a high …

Unpacking Public Sentiment Toward The Government: How Citizens’ Perceptions Of Government Communication Strategies Impact Public Engagement, Cynicism, And Communication Behaviors In South Korea, Soojin Kim, Arunima Krishna

Research Collection Lee Kong Chian School Of Business

In this study, we explore the relationship between two types of public sentiment toward the government (i.e., public engagement and cynicism) on publics’ information transmission behaviors, i.e., megaphoning, about the government. In doing so, we unpack how citizens’ perceptions of the communication strategy adopted by the government, as well perceived authenticity of the government’s communication impact their sentiments toward the government. An online survey was conducted in South Korea (N = 1112) to understand these relationships. The results revealed that perceived use of bridging strategy by the government is associated with public engagement, and perceived use of the buffering strategy …

When Does Limited Commitment Matter In A Production Economy?, Kyoung Jin Choi, Jungho Lee

Research Collection School Of Economics

We investigate the conditions under which the first-best allocation without commitment is sustainable in a production economy. While it is widely known in the literature that allowing capital accumulation creates a distortion, we find that it can help to sustain the first-best allocation. We also find that for a certain set of endowment economiesin which the efficient allocation is not sustainable, the efficient allocation becomes sustainable once we introduce a production technology with very small returns to scale orany returns to scale higher than that of the minimum value. In some cases, gains fromefficient resource allocation between agents can be …

A Dynamic Network Perspective On The Latent Group Structure Of Cryptocurrencies, Li Guo, Yubo Tao, Wolfgang Karl Hardle

Research Collection School Of Economics

In this paper, we study the latent group structure in cryptocurrencies market by forming a dynamic return inferred network with coin attributions. We develop a dynamic covariate-assisted spectral clustering method to detect the communities in dynamic network framework and prove its uniform consistency along the horizons. Applying our new method, we show the return inferred network structure and coin attributions, including algorithms and proof types, jointly determine the market segmentation. Based on the network model, we propose a novel "hard-to-value" measure using the centrality scores. Further analysis reveals that the group with a lower centrality score exhibits stronger short-term return …

Maskin Meets Abreu And Matsushima, Yi-Chun Chen, Takashi Kunimoto, Yifei Sun, Siyang Xiong

Research Collection School Of Economics

We study the classical Nash implementation problem due to Maskin (1999), but allow for the use of lottery and monetary transfer as in Abreu and Matsushima (1992, 1994). We therefore unify two well-established but somewhat orthogonal approaches of implementation theory. We first show that Maskin monotonicity is a necessary and sufficient condition for pure-strategy Nash implementation by a direct mechanism. Second, taking mixed strategies into consideration, we show that Maskin monotonicity is a necessary and sufficient condition for mixed-strategy Nash implementation by a finite (albeit indirect) mechanism. Third, we extend our analysis to implementation in rationalizable strategies. In contrast to …

The Effect Of Non-Contributory Pensions On Labour Supply And Private Income Transfers: Evidence From Singapore, Yanying Chen, Yi Jin Tan

Research Collection School Of Economics

Non-contributory pensions are becoming increasingly prevalent worldwide. As their effects are likely to be context-dependent, evaluating their effects in a wide range of settings is important for establishing the external validity of the non-contributory pension literature. We use a new monthly panel dataset and a difference-in-differences strategy to study the effect of a new non-contributory pension in Singapore (the Silver Support Scheme or SSS) on labour supply, work expectations, private cash transfers, and expenditure, 1 year after its implementation. We find no evidence that receiving SSS payouts led to a fall in labour supply, work expectations, or the receipt of …

Income And Subjective Well-Being: Evidence From Singapore's First National Non-Contributory Pension, Yanying Chen, Yi Jin Tan

Research Collection School Of Economics

We use a new monthly panel and a difference-in-differences strategy to study the effects of an exogenous permanent income shock on subjective well-being along previously unexplored dimensions. This permanent income shock is the introduction of Singapore’s first national non-contributory pension, the Silver Support Scheme. The pension improved the life satisfaction of recipients, and appeared to be driven by social, household income, and economic satisfaction. Consistent with the predictions of standard consumption-savings models, well-being improved when the shock was unanticipated (at announcement), but did not improve significantly further when the shock was anticipated (at disbursement). In addition, we find evidence that …

Scaling The Nexus: Towards Integrated Frameworks For Analysing Water, Energy And Food, Scott J. Mcgrane, Michele Acuto, Francesca Artioli, Po-Yu Chen, Robert Comber, Julian Cottee, Geremy Farr-Wharton, Nicola Green, Ariella Helfgott, Shaun Larcom, Julie A. Mccann, Patrick O'Reilly, Gloria Salmoral, Marian Scott, Lindsay C. Todman, Terry Van Gevelt, Xiaoyu Yan

Research Collection College of Integrative Studies

The emergence of the water–energy–food (WEF) nexus has resulted in changes to the way we perceive our natural resources. Stressors such as climate change and population growth have highlighted the fragility of our WEF systems, necessitating integrated solutions across multiple scales. While a number of frameworks and analytical tools have been developed since 2011, a comprehensive WEF nexus tool remains elusive, hindered in part by our limited data and understanding of the interdependencies and connections across the WEF systems. To achieve this, the community of academics, practitioners and policy-makers invested in WEF nexus research are addressing several critical areas that …

Building A Smart Nation: Singapore’S Digital Journey, Siu Loon Hoe

Research Collection School Of Computing and Information Systems

The journey towards smart city status is a strong global trend as governments around the world strive to harness technology to improve the quality of life for their citizens (United Nations, 2016). The widespread phenomenon of becoming “smart” is a key topic of discussion and research that continues to change as new digital technologies develop (Ishkineeva et al., 2015). The smart cities theme is important because it explores how governments, as providers of public goods, harness digital technologies to improve the lives of citizens around the world in the present and the future.

What Does Embarrassment Have To Do With Our Choice Of Brands?, Singapore Management University

Perspectives@SMU

Everyone experiences moments of embarrassment – when their credit cards are rejected at the checkout, they are wearing their T-shirt inside out, or have to buy tampons or condoms in a store.

When people are embarrassed it is only natural they behave differently to try to make themselves feel better. But how do they cope with feeling embarrassed? What types of strategies do they adopt and how does all this relate to their self-esteem?

Plugged In: Identifying Open (& Subscribed) Access, Aaron Tay

Research Collection Library

Scholars have unprecedented access to subscription and open access (OA) content, yet figuring out how to discover and access legitimate versions of articles remains an aggravating experience for many researchers. They face authentication hoops, myriad vendor platforms with uncertain holdings, and mystifying an obscure OA source. Researchers that start with Google Scholar may bypass library authentication and face paywalls. Conversely, library discovery tools fail to expose and deliver much of the available OA content, and especially under-represent Green OA from repositories. Our panel discusses several approaches to improving access discovery by giving scholars tools to identify accessible content and using …

The Privileged Link: Open Access, Version Of Record, Or Let The User Decide?, Lisa Janicke Hinchliffe, Aaron Tay, Maria Aghazarian, Johan Tilstra

Research Collection Library

As the availability of open access (OA) copies continues to grow, platforms and libraries are increasingly facing the possibility of linking users to version of record copies as well as to OA but non-version of record copies of the same article. Some advocate prioritizing linking to OA copies while others argue that the version of record should be prioritized. In many cases, this is a question of whether to link to a copy that the library has licensed over the copies that are freely available; however, the same conundrum can occur with respect to publisher-hosted OA content vs. copies available …

Winning Combination For Collaboration On Plagiarism: Smu Libraries And Student Council Of Discipline (Scd), Mei Tan

Research Collection Library

Plagiarism in higher education is a reality that will not go away any time soon. In Singapore Management University (SMU) Libraries, we observed that there had been an increase in requests for plagiarism workshops in recent years. We also realised from the onset that conducting library workshops on plagiarism would not be sustainable in the long-run.

Purposeful Building Of Social Capital And The Adoption Of Essential Tools And Technologies In Impoverished Communities In The Philippines, Chon Phung Lim

Dissertations and Theses Collection

Despite its popularity and a wide range of applications, social capital is a contested concept. There is also no agreement on whether social capital responds well to external interventions. Many scholars found no or, at most, mixed impacts that social capital can be purposefully developed. However, Burt and Ranchi (2007) and Janicik and Larrick (2005) provided compelling evidence that simple network training can significantly improve participants’ ability to see gaps in their network and develop social capital.

The manifestations of social capital are context-dependent and complex, and rarely map into a single discipline or methodology (Jones and Woolcock, 2007). Hence, …

When You Don’T Have An Alternative In A Negotiation, Try Imagining One, Michael Schaerer, Martin Schweinsberg, Roderick I. Swaab

Research Collection Lee Kong Chian School Of Business

Conventional wisdom suggests that negotiators need alternatives to succeed. Alternatives give negotiators the confidence to negotiate offers more ambitiously, to push for more optimal outcomes, and to walk away from the table when needed. But negotiators often have no alternative at all. For example, a recent survey by GMAC suggests that the average MBA graduate only has a single job offer to choose from, suggesting that many MBAs have to negotiate their job offer without an alternative to fall back on.

What Is Gab: A Bastion Of Free Speech Or An Alt-Right Echo Chamber, Savvas Zannettou, Barry Bradlyn, Emiliano De Cristofaro, Haewoon Kwak, Michael Sirivianos, Gianluca Stringhini, Jeremy Blackburn

Research Collection School Of Computing and Information Systems

Over the past few years, a number of new "fringe" communities, like 4chan or certain subreddits, have gained traction on the Web at a rapid pace. However, more often than not, little is known about how they evolve or what kind of activities they attract, despite recent research has shown that they influence how false information reaches mainstream communities. This motivates the need to monitor these communities and analyze their impact on the Web's information ecosystem. In August 2016, a new social network called Gab was created as an alternative to Twitter. It positions itself as putting "people and free …

Introducing Basic Programming To Pre-University Students: A Successful Initiative In Singapore, Heng Ngee Mok, Vandana Ramachandra Rao

Research Collection School Of Computing and Information Systems

“Let’s Code!” is an intensive 3-week basic programming course that aims to formally expose pre-university students in Singapore to programming. This course was conducted in blended-learning format, and included lecture videos, self-check quizzes, video conferences, meet-up tutorials and take-home programming assignments. The authors hope to capture the experience gained from running this course for educators who intend to implement similar courses in the future. Besides a detailed description of this course, significant changes that were made based on feedback from participants and members of the teaching team are documented here.

Exploiting User And Venue Characteristics For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Which venue is a tweet posted from? We call this a fine-grained geolocation problem. Given an observed tweet, the task is to infer its discrete posting venue, e.g., a specific restaurant. This recovers the venue context and differs from prior work, which geolocats tweets to location coordinates or cities/neighborhoods. First, we conduct empirical analysis to uncover venue and user characteristics for improving geolocation. For venues, we observe spatial homophily, in which venues near each other have more similar tweet content (i.e., text representations) compared to venues further apart. For users, we observe that they are spatially focused and more likely …

Real World, Large Scale Iot Systems For Community Eldercare: Experiences And Lessons Learned, Alvin Cerdena Valera, Wei Qi Lee, Hwee-Pink Tan, Hwee Xian Tan, Huiguang Liang

Research Collection School Of Computing and Information Systems

The paradigm of aging-in-place - where the elderly live and age in their own homes, independently and safely, with care provided by the community - is compelling, especially in societies that face both shortages in institutionalized eldercare resources, and rapidly-aging populations. When the number of elderly who live alone rises rapidly, support and care from their communities become increasingly critical. Internet-of-Things(IoT) technologies, particularly in-home monitoring solutions, are becoming mature. They can become the fundamental enabler for smart community eldercare. In this chapter, we share our real-world experiencesgleaned from an ongoing large-scale project on IoT-enabled community eldercare. We identify technology-centric challenges …

Detect Rumor And Stance Jointly By Neural Multi-Task Learning, Jing Ma, Wei Gao, Kam-Fai Wong

Research Collection School Of Computing and Information Systems

In recent years, an unhealthy phenomenon characterized as the massive spread of fake news or unverified information (i.e., rumors) has become increasingly a daunting issue in human society. The rumors commonly originate from social media outlets, primarily microblogging platforms, being viral afterwards by the wild, willful propagation via a large number of participants. It is observed that rumorous posts often trigger versatile, mostly controversial stances among participating users. Thus, determining the stances on the posts in question can be pertinent to the successful detection of rumors, and vice versa. Existing studies, however, mainly regard rumor detection and stance classification as …

(Re)Producing Buddhist Hegemony In Sri Lanka: Advancing The Discursive Formations Of Self-Orientalism, Religious (Im)Mobility And 'Unethical' Conversion, Orlando Woods

Research Collection School of Social Sciences

This paper explores how Buddhist groups in Sri Lanka attempt to suppress conversion to Christianity. Conversion to Christianity can dilute the power and legitimacy of Buddhist groups, which has caused them to promote a discourse of ‘unethical’ conversion. My argument is that such a discourse is self-Orientalising in nature, and is designed to enable the (re)production of Buddhist hegemony in Sri Lanka. By constructing Buddhists as vulnerable and in need of protection, the hegemonic actions of Buddhist groups are validated. These constructions serve to restrict the religious (and socio-cultural) mobility of Buddhists, and to legitimise the persecution of Christians through …
