Maximizing Multifaceted Network Influence, Yuchen Li, Ju Fan, George V. Ovchinnikov, Panagiotis Karras

Research Collection School Of Computing and Information Systems

An information dissemination campaign is often multifaceted, involving several facets or pieces of information disseminating from different sources. The question then arises, how should we assign such pieces to eligible sources so as to achieve the best viral dissemination results? Past research has studied the problem of Influence Maximization (IM), which is to select a set of k promoters that maximizes the expected reach of a message over a network. However, in this classical IM problem, each promoter spreads out the same unitary piece of information. In this paper, we propose the Optimal Influential Pieces Assignment (OIPA) problem, which is …

The Myanmar Business Environment Index 2020: Measuring Economic Governance For Private Sector Development, Malesky Edmund, Dean C. Dulay, Jon Kesssecker

Research Collection School of Social Sciences

The Economic Governance Index (EGI) is a tool that has become widely accepted by governments to understand economic growth, attract investors, and engage in public-private sector dialogue. EGIs have been used in Indonesia, Sri Lanka, Bangladesh, Kosovo, El Salvador, Cambodia, Mongolia, and Vietnam to offer crucial insight into governance and help guide reform efforts. The Myanmar Business Environment Index (MBEI) follows in this tradition by adapting the EGI model to the Myanmar context. The MBEI is designed to provide Union and state/region government leaders, as well as stakeholders such as business managers, with a tool to understand and address the …

Measuring And Explaining Political Sophistication Through Textual Complexity, Kenneth Benoit, Kevin Munger, Arthur Spirling

Research Collection School of Social Sciences

Political scientists lack domain-specific measures for the purpose of measuring the sophistication of political communication. We systematically review the shortcomings of existing approaches, before developing a new and better method along with software tools to apply it. We use crowdsourcing to perform thousands of pairwise comparisons of text snippets and incorporate these results into a statistical model of sophistication. This includes previously excluded features such as parts of speech and a measure of word rarity derived from dynamic term frequencies in the Google Books data set. Our technique not only shows which features are appropriate to the political domain and …

Restructured Frame-Of-Reference Training Improves Rating Accuracy, Ming-Hong Tsai, Serena Wee, Brandon Koh

Research Collection School of Social Sciences

The use of heuristic judgments is prevalent in organizations and negatively impacts accurate employee assessments. To minimize the negative impact of heuristic judgments (i.e., anchoring and adjustment), we aim to improve rating accuracy by restructuring frame‐of‐reference (FOR) training. We conducted five studies (N = 1,143) using different samples (three including participants with hiring experience), training environments (onsite and online), and rating contexts (evaluations of sales representatives, teachers, contract negotiation specialists, and retail store managers). Across the five studies, the average improvement in rating accuracy was at least twice as large for restructured FOR (vs. control) training as it was for …

Disjunctures Of Belonging And Belief: Christian Migrants And The Bordering Of Identity In Singapore, Lily Kong, Orlando Woods

Research Collection School of Social Sciences

Migration results in people that are different from one another living in closer physicalproximity. Proximity increases the chances of encountering difference, and can lead to boththe formation of new communities, and the strengthening of old. As a religion that claims tointegrate people into a trans-ethnic, trans-territorial faith community, Christianity encouragessuch encounters, whilst Christian groups play an important role in mediating them.Disjunctures of belonging and belief are the outcomes that arise from encounters withdifference within spaces of Christianity. Drawing on 100 interviews conducted betweenAugust 2017 and February 2018, this paper unravels these disjunctures through a focus on theinterplay between migrant and …

Why Smart Leaders Fail, David Chan

Research Collection School of Social Sciences

In an invited commentary, SMU Behavioural Sciences Institute Director Professor David Chan discussed leadership issues in the Singapore context.

Video Gaming Can Benefit Students: Study, Andree Hartanto, Wei Xing Toh

Research Collection School of Social Sciences

Video gaming is not inherently bad if treated as a form of leisure activity that can help young people to de-stress during the weekends.

An Analysis Of Z-Scores And Performance: Manufacturing Companies In Hong Kong, S.L. Foo, Shaakalya Pathak

Research Collection School Of Accountancy

Hong Kong is a key leading economy in the Asia Pacific region. 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 this market. A linear regression has been conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a five-year period have also been analysed. The analysis covers the period from 2013 to 2017 (inclusive) and yields a statistically positive correlation between ROE and the Z-Score for the market. Hong …

Treating Participation As An Assignment, Brandon Bosch

Department of Sociology: Faculty Publications

Participation is a funny thing. Some of us grade it obliquely, bumping up the final grades for students that were truly exceptional at it. Some of us explicitly state on the syllabus how important it is for students to come to class “ready and willing to participate,” but only allocate 10% of the overall grade to this supposedly valued activity. But perhaps the most common thing that we do as instructors with participation is this: despite the fact that participation is one of the most commonly “submitted” activities in a class, very few instructors treat participation like an actual assignment. …

Mixed Methods In Body And Embodiment Research, Samantha Kwan, Trenton M. Haltom

Department of Sociology: Faculty Publications

This chapter outlines the foundations of mixed methods research and discusses several examples of mixed methods research in the sociology of the body and embodiment. It begins with a brief history of mixed methods and conceptualizations of this term. To illustrate mixed methods in practice, including its benefits, drawbacks, and relevance to intersectionality research, the authors discuss the first author’s research on body weight (Kwan 2007, 2009a, 2009b, 2010; Kwan and Graves 2013), as well as a study about young women’s contraceptive use (England et al. 2016) and a study about nude embodiment (Weinberg and Williams 2010). The chapter concludes …

Global Borders And Borderlands History Symposium Program 2019, Global Borders And Borderlands History Symposium

Global Borders and Borderlands (Archived)

Borders and borderlands have the unique power to simultaneously unite and divide the people living in and around them. Scholars studying all parts of the world recognize the importance of borders and borderlands not only in the geopolitical sense, but also as they impact economics, diplomacy, culture, society, and human identity. The presenters at this symposium study the role of borders—and the complex "borderlands" they create—in shaping global historical narratives, with an aim toward the multidisciplinary integration of themes like gender, race, ethnicity, indigeneity, violence, environment, and material culture.

Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran

Psychology Theses & Dissertations

The purpose of this study was to test Wickens’ Multiple Resource Theory (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of transferring rings from one peg to another and a low workload task that consisted of grasping and placing large pencil erasers in a bowl. It was predicted that the visual-spatial secondary task would be more sensitive when paired with the laparoscopic primary task than the auditory analog. Findings …

Political Culture And Policy: The Impact Of Culture And Values On School Choice Legislation, Heather Leigh Neal

Educational Leadership & Workforce Development Theses & Dissertations

Policy actors unite political culture, power, and values to make substantial decisions which are often subjective in nature. Politics and policy are about collective decisions, which rely on the arrangement of a group of people. As values can influence policy actors in their attempt to solve problems, it is important for policymakers to establish a balance among the most essential values. A qualitative case study approach was used to investigate how, and what ways, political culture influenced how state stakeholders interpreted or implemented policy. Power and values were explored as both can connect for the implementation of policy. If values, …

The Effects Of Supervisory Style And Supervisory Working Alliance On Supervisee Disclosure In Supervision: A Moderated Mediation Analysis, Chi Li

Counseling & Human Services Theses & Dissertations

Supervisee disclosure in supervision is considered as a critical factor influencing the effectiveness of supervision (Spence et al., 2014). Despite previous researchers’ efforts to understand the concept (e.g., Knox, 2015; Yourman & Farber, 1996), a consensus over the definition for what is considered as supervisee disclosure is missing, posing threats to the construct validity of existing supervisee disclosure measures (e.g., Gunn & Pistole, 2012; Mehr, Ladany, & Caskie; 2015). Therefore, based on a summative definition (e.g., Ladany et al., 1996; Hess et al., 2008; Walsh, Gillespie, Greer & Eanes, 2003), Li and Kemer (under review) developed and provided initial validation …

Examining Self-Contained And Integrated Physical Education Experiences Among Individuals With Visual Impairments, Rebecca Coffey

Human Movement Studies & Special Education Theses & Dissertations

Introduction. While research to date has examined the views of individuals with visual impairments toward integrated public-school physical education, little attention has been given to examining perspectives toward experiences at residential schools for those with visual impairments. By understanding the perspectives of those who attended physical education in both contexts, researchers can gain valuable information about particularities that can make experiences meaningful or challenging. The purpose of this study was to examine how individuals who experienced physical education in both integrated and residential school settings viewed their physical education class experiences. Methods. This study utilized a retrospective interpretative phenomenological approach …

Lgbtqia+ Campus Climate At A Small Liberal Arts University: An Exploratory Study With The Aim Of Improving The Environment For Queer Students, Mary Amanda Breeden

Honors Projects

Research suggests that a significant portion of LGBTQIA+ individuals report that their sexual orientation and/or gender identity play a substantial role in choosing which postsecondary institution to attend; thus, it is incumbent upon institutions for higher education to assess their respective campus climates. This project evaluates LGBTQIA+ campus climate at a small, private, Midwestern liberal arts university. Utilizing a grounded theory approach, I interviewed my queer-identified classmates – selected via a combination of strategic and snowball sampling – about their experiences on campus. Through these discussions, I gained a better understanding of queer students’ experiences within the classroom, extracurricular activities, …

An Exploration Of How Early Years Managers And Staff Are Responding To The Needs Of Children Experiencing Homelessness, Jacinta Corcoran

Dissertations

Homelessness in Ireland has increased rapidly over recent years with children and families making up increasing proportions of the numbers recorded whilst single parent families are representing a disproportionate number of families experiencing homelessness. Consequently many early years services are supporting unprecedented numbers of children who are experiencing homelessness to engage and fully participate in early education programmes. The experience of homelessness can permeate many levels and various aspects of a child’s life particularly when historical risks and adversities are to be factored. Within this context this study guided by an ecological framework explores the range of influences on the …

Robustly Optimal Reserve Price, Wei He, Jiangtao Li

Research Collection School Of Economics

We study a robust version of the single-unit auction problem. The auctioneer has confidence in her estimate of the marginal distribution of a generic bidder's valuation, but does not have reliable information about the joint distribution. In this setting, we analyze the performance of second-price auctions with reserve prices in terms of revenue guarantee, that is, the greatest lower bound of revenue across all joint distributions that are consistent with the marginals. For any finite number of bidders, we solve for the robustly optimal reserve price that generates the highest revenue guarantee. Our analysis has interesting implications in large markets. …

Random Coefficient Continuous Systems: Testing For Extreme Sample Path Behavior, Yubo Tao, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper studies a continuous time dynamic system with a random persistence parameter. The exact discrete time representation is obtained and related to several discrete time random coefficient models currently in the literature. The model distinguishes various forms of unstable and explosive behavior according to specific regions of the parameter space that open up the potential for testing these forms of extreme behavior. A two-stage approach that employs realized volatility is proposed for the continuous system estimation, asymptotic theory is developed, and test statistics to identify the different forms of extreme sample path behavior are proposed. Simulations show that the …

Rank Tests At Jump Events, Jia Li, Viktor Todorov, George Tauchen, Huidi. Lin

Research Collection School Of Economics

We propose a test for the rank of a cross-section of processes at a set of jump events. The jump events are either specific known times or are random and associated with jumps of some process. The test is formed from discretely sampled data on a fixed time interval with asymptotically shrinking mesh. In the first step, we form nonparametric estimates of the jump events via thresholding techniques. We then compute the eigenvalues of the outer product of the cross-section of increments at the identified jump events. The test for rank r is based on the asymptotic behavior of the …

M-Estimators Of U-Processes With A Change-Point Due To A Covariate Threshold, Lili Tan, Yichong Zhang

Research Collection School Of Economics

Economic theory often predicts a “tipping point” effect due to multiple equilibria. Linear threshold regressions estimate the “tipping point” by assuming at the same time that the response variable is linear in an index of covariates. However, economic theory rarely imposes a specific functional form, but rather predicts a monotonic relationship between the response variable and the index. We propose new, rank-based, estimators for both the “tipping point” and other regression coefficients, exploiting only the monotonicity condition. We derive the asymptotic properties of these estimators by establishing a more general result for M-estimators of U-processes with a change-point due to …

Asymptotic Theory For Rough Fractional Vasicek Models, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper extends the asymptotic theory for the fractional Vasicek model developed in Xiao and Yu (2018) from the case where H ∈ (1/2, 1) to the case where H ∈ (0, 1/2). It is found that the asymptotic theory of the persistence parameter (k) critically depends on the sign of k. Moreover, if k > 0, the asymptotic distribution for the estimator of k is different when H ∈ (0, 1/2) from that when H ∈ (1/2, 1).

Sieve Estimation Of Time-Varying Panel Data Models With Latent Structures, Liangjun Su, Xia Wang, Sainan Jin

Research Collection School Of Economics

We propose a heterogeneous time-varying panel data model with a latent group structure that allows the coefficients to vary over both individuals and time. We assume that the coefficients change smoothly over time and form different unobserved groups. When treated as smooth functions of time, the individual functional coefficients are heterogeneous across groups but homogeneous within a group. We propose a penalized-sieve-estimation-based classifier-Lasso (C-Lasso) procedure to identify the individuals’ membership and to estimate the group-specific functional coefficients in a single step. The classification exhibits the desirable property of uniform consistency. The C-Lasso estimators and their post-Lasso versions achieve the oracle …

Illusion Of Gender Parity In Education: Intrahousehold Resource Allocation In Bangladesh, Sijia Xu, Abu S. Shonchoy, Tomoki Fujii

Research Collection School Of Economics

A target in the Millennium Development Goals—gender parity in all levels of education—is widely considered to have been attained. However, measuring gender parity only through school enrollment is misleading, as girls may lag behind boys in other educational measures. We investigate this with four rounds of surveys from Bangladesh by decomposing households’ education decisions into enrollment, education expenditure, and share of the education expenditure allocated for the quality of education like private tutoring. We find a strong profemale bias in school enrollment but promale bias in the other two decisions. This contradirectional gender bias is unique to Bangladesh and partly …

Building An Equitable And Inclusive City Through Housing Policies: Singapore’S Experience, Sock Yong Phang

Research Collection School Of Economics

Inequality is an age-old concern. In recent years, the rise of income inequality has received worldwide media and policy attention, beginning with the Occupy movement of 2011-2012 and a wave of notable scholastic books such as Stiglitz (2012), Piketty (2014), and Atkinson (2015). Piketty’s Capital in the 21st Century, an unlikely bestseller, contained a vast amount of data showing that the rich are taking rising shares of income and wealth in the advanced economies. Piketty’s approach towards capital and wealth is an aggregative one, and he does not treat real estate or land as a different or distinct form of …

Evaluating Stakeholder Bias In Stakeholder Analysis In Social Media, Ahmad A. Bajarwan

Engineering Management & Systems Engineering Theses & Dissertations

Stakeholder analysis is the first step in the planning of most infrastructure projects. Selecting and then applying the best method for a project’s stakeholder analysis is extremely important for correctly assessing stakeholder opinions. Social media platforms allow stakeholders to participate directly in analysis. However, as with most other analysis methods, social media introduces inherent biases.

Social media is a powerful tool for communication and networking, and it also provides a valuable source of information for analyzing user opinions about infrastructure projects. By using data collected from Twitter, analysts can create networks to represent connections among users, quantify their similarities, and …

Comparing Higher Order Value Differences By Religious And Spiritual Association And Implications For Counseling: An Exploratory Study, Gregory C. Lemich

Counseling & Human Services Theses & Dissertations

The spiritual but not religious (SBNR) population in the U.S. has grown into a significant minority demographic (27%; Lipka & Gecewicz, 2017). Despite this emergence, scant literature has addressed this population and how it differs in values from others, specifically, how SBNR groups differ from those who identify as spiritual and religious (SAR), religious but not spiritual (RBNS), and not spiritual or religious (NSOR). To help this deficiency, this dissertation study explored the intersection of spirituality, religiosity, spiritual and religious categories (SRC; i.e. SAR, SBNR, RBNS, NSOR), and the theory of basic human values (Schwartz, 1992, 1994; Schwartz et al., …

The Relationship Between Identity Dimensions, Gender Conformity, And Satisfaction With Life, Alexandria Colburn

Master's Theses (2009 -)

There is a large body of evidence indicating physical and mental health disparities among marginalized populations. The purpose of this study was to examine the relationship between identity dimensions, gender conformity, and well-being. I anticipated that identification with a marginalized identity group would predict poorer satisfaction with life, compared to identification with a privileged group. In addition, I investigated the role of gender conformity as a possible interaction variable in the relationship between identity factors (assigned sex, age, race, ethnicity, and sexual orientation) and outcomes of satisfaction with life. A hierarchical multiple regression was used to investigate these hypotheses. Results …

Reshaping Counselor Education: The Identification Of Influential Factors On Multisystemic Therapy, T'Airra C. Belcher

Counseling & Human Services Theses & Dissertations

Multisystemic therapy (MST) is a form of behavioral health treatment for adolescents which has been identified as one of the leading effective forms of treatment for children and adolescents with severe behavioral and mental health disorders. Since its creation, there have been countless studies exploring if this form of treatment works with a different population in a variety of locations. Additionally, there have been studies which determined that MST is just as effective as or even less effective than other treatment modalities. This dissertation explored the specific aspects of MST and what leads to its effectiveness. A meta-analysis and case …

Estimating Cognitive Workload In An Interactive Virtual Reality Environment Using Electrophysiological And Kinematic Activity, Christoph Tremmel

Biomedical Engineering Theses & Dissertations

As virtual reality (VR) technology continues to gain prominence in commercial, educational, recreational and research applications, there is increasing interest in incorporating physiological sensors in VR devices for passive user-state monitoring to eventually increase the sense of immersion. By recording physiological signals such as the electroencephalogram (EEG), electromyography (EMG) or kinematic parameters during the use of a VR device, the user’s interactions in the virtual environment could be adapted in real time based on the user’s cognitive state. This dissertation evaluates the feasibility of passively monitoring cognitive workload via electrophysiological and kinematic activity while performing a classical n-back task in …
