Integrated Deviance Information Criterion For Latent Variable Models, Yong Li, Jun Yu, Tao Zeng

Research Collection School Of Economics

Deviance information criterion (DIC) has been widely used for Bayesian model comparison, especially after Markov chain Monte Carlo (MCMC) is used to estimate candidate models. This paper studies the problem of using DIC to compare latent variable models after the models are estimated by MCMC together with the data augmentation technique. Our contributions are twofold. First, we show that when MCMC is used with data augmentation, it undermines theoretical underpinnings of DIC. As a result, by treating latent variables as parameters, the widely used way of constructing DIC based on the conditional likelihood, although facilitating computation, should not be used. …

On Random Social Choice Functions With The Tops-Only Property, Shurojit Chatterji, Huaxia Zeng

Research Collection School Of Economics

We study the standard voting model with randomization. A Random Social Choice Function (or RSCF) satisfies the tops-only property if the social lottery under each preference profile depends only on the peaks of voters' preferences. We identify a general condition on domains of preferences (the Interior Property and the Exterior Property) which ensures that every strategy-proof RSCF satisfying unanimity has the tops-only property. We show that our condition applies to important classes of voting domains which include restricted connected domains (Sato, 2013) and the multi-dimensional single-peaked domain (Barberà et al., 1993). As an application of our result, we show that …

Limit Theory For Mildly Integrated Process With Intercept, Yijie Fei

Research Collection School Of Economics

Some asymptotic results are given for first-order autoregressive (AR(1)) time series with two features: (i). a nonzero constant intercept (ii). a root moderately deviating from unity. Both stationary and explosive sides are studied. It is shown that the inclusion of intercept will change drastically the large sample properties of the least-squares (LS) estimator obtained in Phillips and Magdalinos (2007, PM hereafter). For near-stationary case, only an unusual convergence of a linear combination of intercept and AR coefficient can be derived. For near-explosive case, on the other hand, the limiting distributions of two estimators will be independent and Gaussian, with conventional …

Barriers To Labor Migration For The Rural Poor: Experimental Evidence From A Vocational Training Program In Bangladesh, Abu S. Shonchoy, Tomoki Fujii, Selim Raihan

Research Collection School Of Economics

Vocational training programs aimed at rapidly growing sectors have the potential to reduce skill gaps as well as improve income and employment possibilities. Such programs have often been unsuccessful because they are not driven by industry demand and market linkages. Also, they do not tackle other barriers faced by trainees, such as savings and credit constraints and the uncertainty of migration. We introduced a training "plus'' program for the apparel sector jobs offered to the poor, rural households in northern Bangladesh, where we relaxed some of these constraints in a rigorous Randomized Control Trial (RCT) setting. Analyzing the program uptake …

A Large Class Of Strategy-Proof Exchange Rules With Single-Peaked Preferences, Peng Liu

Research Collection School Of Economics

We study the classical house exchange problem (Shapley and Scarf (1974)) and identified a large class of rules, each of which is strategy-proof, efficient, and individually rational with single-peaked preferences. These rules are generalisations of Gale’s top trading cycles rule: In each step a subset of houses are allowed to be traded along top trading cycles and in particular, the next step subset of trading houses may depend on the exchanges happened already. We believe that the flexibility introduced by this class of rules is desirable when the designer faces some context-specific requirements.

Industrial Output Fluctuations In Developing Countries: General Equilibrium Consequences Of Agricultural Productivity Shocks, Iona Hyojung Lee

Research Collection School Of Economics

This paper shows that a negative shock to agricultural productivity may increase food prices, and labor and capital can move away from manufacturing into agriculture to meet the subsistence requirement for food. This effect depends on income levels and openness to trade. Using annual manufacturing data and rainfall shocks as the instrument for crop yields (proxy for agricultural productivity), I find that an exogenous decline in yield decreases manufacturing output as well as employment and capital investment in manufacturing. Overall, crop yield variation can explain up to 44% of industrial output fluctuations in developing countries (rainfall shocks cause 31% of …

Upping The Game Of Taxi Driving In The Age Of Uber, Shashi Shekhar Jha, Shih-Fen Cheng, Meghna Lowalekar, Wai Hin Wong, Rajendram Rishikeshan Rajendram, Trong Khiem Tran, Pradeep Varakantham, Nghia Truong Trong, Firmansyah Abd Rahman

Research Collection School Of Computing and Information Systems

In most cities, taxis play an important role in providing point-to-point transportation service. If the taxi service is reliable, responsive, and cost-effective, past studies show that taxi-like services can be a viable choice in replacing a significant amount of private cars. However, making taxi services efficient is extremely challenging, mainly due to the fact that taxi drivers are self-interested and they operate with only local information. Although past research has demonstrated how recommendation systems could potentially help taxi drivers in improving their performance, most of these efforts are not feasible in practice. This is mostly due to the lack of …

Resource-Constrained Scheduling For Maritime Traffic Management, Lucas Agussurja, Akshat Kumar, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

We address the problem of mitigating congestion and preventing hotspots in busy water areas such as Singapore Straits and port waters. Increasing maritime traffic coupled with narrow waterways makes vessel schedule coordination for just-in-time arrival critical for navigational safety. Our contributions are: 1) We formulate the maritime traffic management problem based on the real case study of Singapore waters; 2) We model the problem as a variant of the resource-constrained project scheduling problem (RCPSP), and formulate mixed-integer and constraint programming (MIP/CP) formulations; 3) To improve the scalability, we develop a combinatorial Benders (CB) approach that is significantly more effective than …

The Evolutionary Mismatch Hypothesis: Implications For Psychological Science, Norman P. Li, Mark Van Vugt, Stephen M. Colarelli

Research Collection School of Social Sciences

Human psychological mechanisms are adaptations that evolved to process environmental inputs, turning them into behavioral outputs that, on average, increase survival or reproductive prospects. Modern contexts, however, differ vastly from the environments that existed as human psychological mechanisms evolved. Many inputs now differ in quantity and intensity or no longer have the same fitness associations, thereby leading many mechanisms to produce maladaptive output. We present the precepts of this evolutionary mismatch process, highlight areas of mismatch, and consider implications for psychological science and policy.

Strategies Of Salvation: Evangelical Christian Praxis And Sites Of Degradation In Sri Lanka, Orlando Woods

Research Collection School of Social Sciences

This paper demonstrates how disasters create sites of degradation – potent spaces of upheaval and engagement – that are readily filled and exploited by evangelical Christian groups. In doing so, it explores how disasters provide opportunities for evangelical groups to gain a foothold in localities where Christian presence, and evangelical praxis, may otherwise be restricted. Drawing on qualitative data collected in Sri Lanka throughout 2010–2011, two comparative case studies are presented that reveal the strategies of evangelical Christian praxis in and through sites of environmental and political degradation. Specifically, the case studies reveal how evangelical groups pursue ‘outside‐in’ and ‘inside‐out’ …

Judgments Of Interpersonal Warmth Predict Class-Based Differences In Political Candidate Support, Jacinth J. X. Tan, Michael W. Kraus

Research Collection School of Social Sciences

The present research examines how warmth communications shape classbased patterns of political candidate support. Drawing on theory and evidence that lower-class individuals are more attuned to others, we predicted that, relative to upper-class individuals, they will modulate their trust and support in response to communications of warmth generated by and about political figures. In Experiment 1, lower-class compared to upper-class participants reported less trust and support for a political candidate who communicated his warmth in a campaign video, while no class differences emerged when he communicated competence or hostility to an opponent instead. In Experiment 2, lower-class compared to upper-class …

Buddhism Co. Ltd? Epistemology Of Religiosity, And The Re-Invention Of A Buddhist Monastery In Hong Kong, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This article re-theorises the relationships between secularity and religiosity in modernity. While geographers have recognised that the secular and the religious are mutually constituted, this article pushes this theorisation further, arguing that the religious and the secular are in fact hybrid constructs that embrace simultaneously the sacred and profane, the transcendent and the immanent. Albeit the significant advancement in disrupting enclosed epistemologies of secular modernity, relatively less work has sought to theorise the possibility of religion as a hybrid operating at the secular–religious interface. Focusing on the ways in which a non-Western religion, Buddhism, performs entangled relationships between religiosity and …

Bridging Academic And Practice: Benefits, Challenges And Lessons Learnt From Establishing A University Wide Experiential Learning Initiative, Gary Pan, Poh Sun Seow, Grace Koh

Research Collection School Of Accountancy

The scale and complexity of challenges facing the world today are unprecedented. It is paramount that universities identify and equip students with relevant skills to meet the needs of the changing economy. Recognizing this need, Singapore Management University launched a new initiative, SMUX. In this paper we will describe SMU-X which is a paradigm shift focusing on experiential learning as opposed to teaching, characterized by 4 principles: (i) inter-disciplinary content and activities, (ii) project-based learning via an actual problem/issue faced by an organization, (iii) active student mentoring by faculty and industry, and (iv) creating a tripartite learning loop between faculty, …

The Value Of Green Certification In The Singapore Housing Market, Eric Fesselmeyer

Research Collection College of Integrative Studies

In Singapore, a real estate developer sells new apartments in the same high-rise development before and after obtaining green certification. This allows the use of within-development variation in prices over time to measure the effect of green certification on housing prices, controlling for differences across developments. I find that green certification increases prices by around 3%, suggesting that buyers value certification, possibly because it signals the presence of less-salient green features. Moreover, the effect of certification is biggest for developments that receive the lowest green rating, which likely have fewer green features and are thus less obviously green.

Sgca Grants Senior Indian Advocate Ad Hoc Admission To Argue Arbitration-Related Applications, Aaron Yoong, Kartik Singh, Aaron Yoong

Research Collection Yong Pung How School Of Law

In a reversal of the High Court’s 2017 decision, Singapore’s Court of Appeal (“CA”) recently granted unprecedented ad hoc admission for Harish Salve (“Mr Salve”) – a Senior Advocate of the Indian Bar – to be admitted to argue foreign law issues in applications to set aside an ICC arbitral award. This is the first time the Singapore courts have granted foreign counsel other than Queen’s Counsel admission to argue a case before the local courts.

An Evaluation Of The 2016 Election Polls In The United States, Courtney Kennedy, Mark Blumenthal, Scott Clement, Joshua D. Clinton, Claire Durand, Charles Franklin, Kyley Mcgeeney, Lee Miringoff, Kristen M. Olson, Douglas Rivers, Lydia Saad, G. Evans Witt, Christopher Wlezien

Department of Sociology: Faculty Publications

The 2016 presidential election was a jarring event for polling in the United States. Preelection polls fueled high-profile predictions that Hillary Clinton’s likelihood of winning the presidency was about 90 percent, with estimates ranging from 71 to over 99 percent. When Donald Trump was declared the winner of the presidency, there was a widespread perception that the polls failed. But did the polls fail? And if so, why? Those are among the central questions addressed by an American Association for Public Opinion Research (AAPOR) ad hoc committee. This paper presents the committee’s analysis of the performance of preelection polls in …

Discovery Orientation, Cognitive Schemas, And Disparities In Science Identity In Early Adolescence, Patricia Wonch Hill, Julia Mcquillan, Amy Spiegel, Judy Diamond

Department of Sociology: Faculty Publications

Why are some youth more likely to think of themselves as a science kind of person than others? In this paper, we use a cognitive social-theoretical framework to assess disparities in science identity among middle school–age youth in the United States. We investigate how discovery orientation is associated with science interest, perceived ability, importance, and reflected appraisal, and how they are related to whether youth see themselves, and perceive that others see them, as a science kind of person. We surveyed 441 students in an ethnically diverse, low-income middle school. Gender and race/ethnicity are associated with science identity but not …

Poor Parenting, Attachment Style, And Dating Violence Perpetration Among College Students, Brian Ermon Tussey, Kimberly A. Tyler, Leslie Gordon Simons

Department of Sociology: Faculty Publications

Although dating violence is prevalent among college students, little is known about how both attachment style and participation in risky behaviors contribute to this pattern of violence. To address this literature gap, we examine the role of poor parenting, child abuse, attachment style, and risky sexual and drug use behaviors on dating violence perpetration among 1,432 college students (51% female). Path analysis results revealed that females were more likely to report greater attachment anxiety but lower attachment avoidance compared with males. Correlates of attachment anxiety included child physical abuse, witnessing parental violence, and poorer maternal relationship quality whereas attachment avoidant …

Recent Advances In The Understanding Of Relationship Communication During Military Deployment, Steven L. Sayers, Galena K. Rhoades

Psychology: Faculty Scholarship

In recent decades, there has been a dramatic increase in the ability of service members and their intimate partners to communicate while the service member is deployed to a combat zone. Communication among partners is a crucial aspect of intimate relationships that has been demonstrated to be highly associated with couples’ satisfaction. In addition, it is often cited by unhappy partners as a primary relationship problem. This special section of the Journal of Family Psychology presents five articles investigating deployment communication among service members and their intimate partners. The studies address the content and goals of deployment communication, the relations …

Theoretical Explanations Of Jyoshi Kousei Business ("Jk Business") In Japan, Mutsumi Ogaki

Dignity: A Journal of Analysis of Exploitation and Violence

Jyoshi kousei (JK) means high school girls in Japanese and “JK business” is an umbrella term for commercial activities done by high school girls to provide male customers with sexual arousal. The “JK business” is considered to promote sexual exploitation or sexual assault of minors. Currently, only two prefectures out of 47 in Japan enforce ordinances that specifically regulate the “JK business.” This paper intends to explore possible theoretical explanations of the “JK business” to raise awareness on the issue. Gendered pathways theory and sexual script theory are selected as the primary source of the discussions. Policy implications and future …

Life Together And Conflict Resolution, Denis Fortin

Faculty Publications

While we celebrate and are proud of the heritage we personally own and cherish, no cultural group or ethnic group is perfect. Human history teaches us that every culture is sinful, in need of God’s grace, for the harm done to the different person, the immigrant, the poor and powerless, the neighboring cultural or ethnic group. Each culture has its history of violence done in the name of some value or historical reason, if not in the name of God. No culture is sinless and perfect, and all are in need of the grace of God.

God invites us to …

Avoiding The Trap: Us Strategy And Policy For Competing In The Asia-Pacific Beyond The Rebalance

Books, Monographs & Collaborative Studies

The pivot to Asia is over, suggested Susan Thornton, Acting Assistant Secretary of State, Bureau of East Asian and Pacific Affairs, on the eve of Secretary of State Rex Tillerson’s first visit to Asia on March 14, 2017.1 This statement, though expected, begs many questions: Is this just a repeal of the bumper sticker “Strategic Rebalance,” typical of administration change? If so, what is its replacement? Moreover, if this change is just in name but not in substance, will President Donald Trump stay the course? If not, what will be Trump’s policy toward the Asia-Pacific? What should be the new …

To Fall In Love With Math, Do This, Susan D'Agostino

Journal of Humanistic Mathematics

In the viral New York Times essay, “To Fall in Love with Anyone, Do This,” Mandy Len Catron details an experience she and an acquaintance had as they shared responses to psychologist Arthur Aron’s thirty-six questions intended to make participants fall in love. She notes that, “we all have a narrative of ourselves that we offer up to strangers and acquaintances, but Dr. Aron’s questions make it impossible to rely on that narrative.” In this paper, we claim that we also have narratives of our relationship to mathematics that we offer up to ourselves and others. Following, we offer a …

Predicting The Next Us President By Simulating The Electoral College, Boyan Kostadinov

Journal of Humanistic Mathematics

We develop a simulation model for predicting the outcome of the US Presidential election based on simulating the distribution of the Electoral College. The simulation model has two parts: (a) estimating the probabilities for a given candidate to win each state and DC, based on state polls, and (b) estimating the probability that a given candidate will win at least 270 electoral votes, and thus win the White House. All simulations are coded using the high-level, open-source programming language R. One of the goals of this paper is to promote computational thinking in any STEM field by illustrating how probabilistic …

Reading The History Of Place-Making Through Maps, Claire Campbell

Sponsored Events -- List

Environmental History explores the relationships between people(s) and nature in the past. So “place- making” – ways in which people have transformed nature to construct habitats of their choosing – is a major theme in the field. Using historical maps and landscape art, Professor Campbell explores some of the historical processes (many of which are still at work) by which settler society has made places in North America. These include practices of colonization, property, public memory, and, potentially, reclamation. We can see the implications for sustainability, and what may need to change.

The Construction Of The African Slave Identity: Defying Hegemony Through Syncretic Religious Practices, Caleigh Dwyer

Denison Journal of Religion

“The Construction of the African Slave Identity: Defying Hegemony through Syncretic Religious Practices” by Caleigh Dwyer, ’19. Dwyer examines the extent to which traditional African culture and the Protestantism with which new slaves were confronted helped them resist the hegemonic structure of American slavery. She argues that the Protestant church acted as a tool, or framework, for collective organization and a restructuring of African identity. African slaves, then, found agency and an opportunity for self-definition through “Africanizing” the Protestant church after white slavers fragmented and suppressed African culture. However, African slave culture made its mark on the Protestant church just …

When We Get Up Yonder, We Shall Have Them Rights Restored To Us: Sojourner Truth’S “The Injustice Of Slavery” And The Rhetoric Of Black Liberation Theology Of Hope, Nordia Bennett

Denison Journal of Religion

“’When We Get Up Yonder, We Shall Have Them Rights Restored To Us:’ Sojourner Truth’s ‘The Injustice of Slavery’ and the Rhetoric of Black Liberation Theology of Hope” by Nordia Bennett, ’17. Bennett situates her reading of Sojourner Truth’s famous speech in the black liberation theology of James Cone, connecting Truth’s views of Jesus’ actions with Cone’s historical, Jewish Jesus. Her analysis continues with a mention of the socioeconomic circumstances of black people as expressed in Truth’s speech, connecting these observations to modern scholarship regarding the injustices of modern economics. Finally, she reads Truth in the light of Jurgen Moltmann, …

“Gospel Of Grace”: Understanding “Amazing Grace” With Musical And Theological Analysis, Ellie Hasan

Denison Journal of Religion

“Gospel of Grace: Understanding ‘Amazing Grace’ with Musical and Theological Analysis” by Ellie Hasan, ’18. Hasan dispels the myth that the classic American hymnal ‘Amazing Grace’ was originally a slave spiritual, utilizing historical scholarship to attribute its authorship to an eighteenth century white slave trader. That the piece found its home in the black gospel canon is a testament to the transformational, liberating nature of gospel music. Hasan touches upon the theological aspects of gospel music that made ‘Amazing Grace’ a natural addition to the gospel canon, taking care to center her scholarship in the musical qualities of gospel practices …
