An Improved Learnable Evolution Model For Solving Multi-Objective Vehicle Routing Problem With Stochastic Demand, Yunyun Niu, Detian Kong, Rong Wen, Zhiguang Cao, Jianhua Xiao

Research Collection School Of Computing and Information Systems

The multi-objective vehicle routing problem with stochastic demand (MO-VRPSD) is much harder to tackle than other traditional vehicle routing problems (VRPs), due to the uncertainty in customer demands and potentially conflicted objectives. In this paper, we present an improved multi-objective learnable evolution model (IMOLEM) to solve MO-VRPSD with three objectives of travel distance, driver remuneration and number of vehicles. In our method, a machine learning algorithm, i.e., decision tree, is exploited to help find and guide the desirable direction of evolution process. To cope with the key issue of "route failure" caused due to stochastic customer demands, we propose a …

Gp3: Gaussian Process Path Planning For Reliable Shortest Path In Transportation Networks, Hongliang Guo, Xuejie Hou, Zhiguang Cao, Jie Zhang

Research Collection School Of Computing and Information Systems

This paper investigates the reliable shortest path (RSP) problem in Gaussian process (GP) regulated transportation networks. Specifically, the RSP problem that we are targeting at is to minimize the (weighted) linear combination of mean and standard deviation of the path's travel time. With the reasonable assumption that the travel times of the underlying transportation network follow a multi-variate Gaussian distribution, we propose a Gaussian process path planning (GP3) algorithm to calculate the a priori optimal path as the RSP solution. With a series of equivalent RSP problem transformations, we are able to reach a polynomial time complexity algorithm with guaranteed …

On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle

Research Collection College of Integrative Studies

This paper explores popular expectations for and meanings of the U.S. West's environmental future, as articulated through recent artistic representations of the Los Angeles's expansive water provision network. Weaving together material from participant observation and readings of creative works, I show how infrastructural imagery is used to index anxieties about a future of water scarcity. Presenting familiar, currently functional water infrastructures as ruins-in-the-making, these artists use the physical stuff of water provision networks to advance critiques of longstanding modes of development and the material basis of urban-rural relations in the U.S. West. Doing so, these imagined ruins draw the global-scale …

Dynamic Lane Traffic Signal Control With Group Attention And Multi-Timescale Reinforcement Learning, Qize Jiang, Jingze Li, Weiwei Sun, Baihua Zheng

Research Collection School Of Computing and Information Systems

Traffic signal control has achieved significant success with the development of reinforcement learning. However, existing works mainly focus on intersections with normal lanes with fixed outgoing directions. It is noticed that some intersections actually implement dynamic lanes, in addition to normal lanes, to adjust the outgoing directions dynamically. Existing methods fail to coordinate the control of traffic signal and that of dynamic lanes effectively. In addition, they lack proper structures and learning algorithms to make full use of traffic flow prediction, which is essential to set the proper directions for dynamic lanes. Motivated by the ineffectiveness of existing approaches when …

Wild Bootstrap For Instrumental Variable Regressions With Weak And Few Clusters, Wenjie Wang, Yichong Zhang

Research Collection School Of Economics

We study the wild bootstrap inference for instrumental variable (quantile) regressions in the framework of a small number of large clusters, in which the number of clusters is viewed as fixed and the number of observations for each cluster diverges to infinity. For subvector inference, we show that the wild bootstrap Wald test with or without using the cluster-robust covariance matrix controls size asymptotically up to a small error as long as the parameters of endogenous variables are strongly identified in at least one of the clusters. We further develop a wild bootstrap Anderson-Rubin (AR) test for full-vector inference and …

Jobs For Justice(S): Corruption In The Supreme Court Of India, Madhav S. Aney, Shubhankar Dam, Giovanni Ko

Research Collection School Of Economics

We investigate whether judicial decisions are affected by career concerns of judges by analyzing two questions: Do judges respond to incentives to pander by ruling in favor of the government in the hope of receiving jobs after retiring from the Supreme Court? Does the government reward judges who rule in its favor with prestigious jobs? We construct a data set of Supreme Court of India cases involving the government for 1999–2014. We find that incentives to pander have a causal effect on judicial decision-making, and they are jointly determined by the importance of the case and whether the judge retires …

Volatility Coupling, Jean Jacod, Jia Li, Zhipeng Liao

Research Collection School Of Economics

This paper provides a strong approximation, or coupling, theory for spot volatility estimators formed using high-frequency data. We show that the t-statistic process associated with the nonparametric spot volatility estimator can be strongly approximated by a growing-dimensional vector of independent variables defined as functions of Brownian increments. We use this coupling theory to study the uniform inference for the volatility process in an infill asymptotic setting. Specifically, we propose uniform confidence bands for spot volatility, beta, idiosyncratic variance processes, and their nonlinear transforms. The theory is also applied to address an open question concerning the inference of monotone nonsmooth integrated …

Financing Singapore’S Smes And The Crowdfunding Industry In Singapore, Swee Liang Tan, Yoke Wang Tok, Chansriniyom Thitipat

Research Collection School Of Economics

As new digital technologies emerge that make the provision of financial services more efficient, they hold the potential to address barriers that SMEs face in accessing credit. This paper finds empirical evidence that crowdfunding for SMEs improved SMEs’ timeliness to pay debt in Singapore. Anecdotal evidence from growing SMEs suggests that getting crowdfunding loans also induced financing from banks, leading to more efficient allocation of credit. In just four years, Singapore’s crowdfunding volume has grown rapidly making it one of the top crowdfunding hubs in Southeast Asia in 2018. The rapid development of Singapore’s crowdfunding industry can be attributed to …

Psychology And The Threat Of Contagion: Feeling Vulnerable To A Disease Moderates The Link Between Xenophobic Thoughts And Support For Ingroup-Protective Actions, Heejung S. Kim, Kimin Eom, Roxie Chuang, David K. Sherman

Research Collection School of Social Sciences

The widespread threat of contagious disease disrupts not only everyday life but also psychological experience. Building on findings regarding xenophobic responses to contagious diseases, this research investigates how perceived vulnerability to a disease moderates the psychological link between people’s xenophobic thoughts and support for ingroup-protective actions. Three datasets collected during the time of Ebola (N = 867) and COVID-19 (Ns = 992 and 926) measured perceived disease risk, group-serving biases (i.e., xenophobic thoughts), and support for restrictive travel policies (i.e., ingroup-protective actions). Using correlational and quasi-experimental analyses, results indicated that for people who perceive greater disease risk, the association between …

A Critical Review On The Moderating Role Of Contextual Factors In The Associations Between Video Gaming And Well-Being, Andree Hartanto, Verity Yu Qing Lua, Frosch Yi Xuan Quek, Jose C. Yong, Matthew H. S. Ng

Research Collection School of Social Sciences

The appeal of video gaming has undoubtedly withstood the test of time. In view of its increasing popularity, lay people and researchers alike have taken an interest in the psychological consequences of video gaming. However, there seems to be a paradox associated with the effect of video gaming on gamers' well-being—namely, while most video game players cite “fun” as their motivation to play video games, video games continue to hold a notorious reputation among some researchers for being detrimental to mental health and emotional well-being as measured by indicators such as happiness, perceived stress, anxiety, and depressive symptoms. We suggest …

Subjective Age And Inflammation Risk In Midlife Adults: Findings From The Midlife In The United States (Midus) Studies, Andree Hartanto, Nadyanna M. Majeed, Wee Qin Ng, Colin Kai Ning Chai, Verity Yu Qing Lua

Research Collection School of Social Sciences

Recent studies have suggested that subjective age—a subjective evaluation of one's own age—is a promising construct in gerontology that may contribute our understanding of risk for immune dysfunction. Nevertheless, studies documenting the association between subjective age and inflammatory biomarkers remain limited and provide mixed findings. In the present study, we revisited the relation between subjective age and systemic inflammation by utilizing a range of well-established inflammatory biomarkers (C-reactive protein, interleukin-6, fibrinogen, E-selectin, and intercellular adhesion molecule 1) through the collection of fasting blood samples before breakfast. In a large-scale dataset of midlife adults (N = 1800), we found some evidence …

Beyond The "Formidable Circle": Race And The Limits Of Democratic Inclusion In Tocqueville's Democracy In America, Christine Dunn Henderson

Research Collection School of Social Sciences

Despite his assertion that the first volume of Democracy in America (1835) would concentrate upon institutions, Tocqueville found himself finishing the draft manuscript in 1834 and unable to conclude his study without discussing race relations in the United States. In the end, he quickly penned a final chapter. That chapter—by far the book’s longest—offers “Some Considerations on the Present State and Probable Future of the Three Races That Inhabit the Territory of the United States.” Tocqueville begins the chapter by acknowledging that its subject “is American without being democratic” (DA, p. 516), and to the extent that it analyzes slavery …

A Multi-Country Test Of Brief Reappraisal Interventions On Emotions During The Covid-19 Pandemic, Ka Wang, Amit Goldenberg, Charles Dorison, Et Al., Nadyanna Mohamed Majeed, Andree Hartanto

Research Collection School of Social Sciences

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across …

We’Re In A Climate Casino: Here’S How To Fight Against The Odds, Winston T. L. Chow

Extreme weather events point to an increasingly dangerous roulette game we play. Individuals and businesses can do their part but governments must do more at the upcoming Glasgow climate conference.

When A Pandemic Disrupts The Export Of People, Yasmin Y. Ortiga, Karen Anne S. Liao

Research Collection School of Social Sciences

Yasmin Ortiga and Karen Anne S. Liao conducted research supported by the SSRC on the dramatic disruptions that Filipino labor migrants experienced as a result of the Covid-19 pandemic, and the support (or lack thereof) of their plight by the Filipino state. Arguing that labor as well as commodity supply chains have been thrown in upheaval, the authors describe the limits of the Philippines’ labor export strategy. In particular, they focus on two sets of labor migrants—nurses unable to take jobs abroad, and repatriated cruise ship workers—for whom dignified work at home was unavailable. Ortiga and Liao conclude that treating …

Glivenko-Cantelli Theorems For Integrated Functionals Of Stochastic Processes, Jia Li, Congshan Zhang, Yunxiao Liu

Research Collection School Of Economics

We prove a Glivenko-Cantelli theorem for integrated functionals of latent continuous-time stochastic processes. Based on a bracketing condition via random brackets, the theorem establishes the uniform convergence of a sequence of empirical occupation measures towards the occupation measure induced by underlying processes over large classes of test functions, including indicator functions, bounded monotone functions, Lipschitz-in-parameter functions, and Hölder classes as special cases. The general Glivenko-Cantelli theorem is then applied in more concrete high-frequency statistical settings to establish uniform convergence results for general integrated functionals of the volatility of efficient price and local moments of microstructure noise.

The Impact Of Climate Change On The Cost Of Bank Loans, Siamak Javadi, Abdullah Al Masum

Economics and Finance Faculty Publications and Presentations

We find that firms in location with higher exposure to climate risk pay significantly higher spreads on their bank loans. This result is robust to different measures of climate risk. Exploiting the economic link between a firm and its customers, we find that the exposure of a firm’s customers to climate risk adversely affects that firm’s cost of borrowing. In the cross-section, we find that the effect is mainly driven by long-term loans of poorly rated firms that are highly exposed to climate risk. Overall, our evidence suggests a slow increase in lenders’ attention to climate risk and that lenders …

The Relationship Between Self-Reported Measures Of Anxiety And Sensory Processing, Elizabeth R. Troutwine

MSU Graduate Theses

Auditory sensory gating, a type of sensory processing, is a physiological mechanism that allows the brain to filter out and respond less to redundant sensory information. Poor sensory gating has been found in clinical groups such as Alzheimer’s dementia (Jessen et al., 2001), bipolar I disorder (Lijffijt et al., 2009), schizophrenia (Patterson et al., 2008), and other anxiety-related psychopathologies such as panic disorder (Ghisolfi et al., 2006), post-traumatic stress disorder (PTSD) (Orr et al., 2002), and obsessive-compulsive-disorder (OCD) (Hashimoto, 2007). Research is limited regarding effects of chronic worry and anxiety on sensory gating ability. This study will explore the relationship …

Using Free And Open Source Software To Teach University Gis Courses Online: Lessons Learned During A Pandemic, Sterling Quinn

Geography Faculty Scholarship

During the remote learning necessitated by the COVID-19 pandemic, university GIS students did not always have home access to the kinds of software and hardware that they would ordinarily get in their on-campus lab facilities. In this situation, the free and cross-platform nature of FOSS opened the door for some students to continue their GIS education uninterrupted. In this article, I describe how one university allowed students to choose FOSS such as QGIS, PostGIS, and GeoDa as alternatives to proprietary software in upper-division GIS coursework. These were used to teach techniques such as point pattern analysis, visibility analysis, hydrological modeling, …

Using Generalizability Theory And The Erp Reliability Analysis (Era) Toolbox For Assessing Test-Retest Reliability Of Erp Scores Part 1: Algorithms, Framework, And Implementation, Scott A. Baldwin, Peter E. Clayson, Kalie A. Carbine, Joseph A. Olsen, Michael J. Larson

Faculty Publications

The reliability of event-related brain potential (ERP) scores depends on study context and how those scores will be used, and reliability must be routinely evaluated. Many factors can influence ERP score reliability; generalizability (G) theory provides a multifaceted approach to estimating the internal consistency and temporal stability of scores that is well suited for ERPs. G theory's approach possesses a number of advantages over classical test theory that make it ideal for pinpointing sources of error in observed scores. The current primer outlines the G-theory approach to estimating internal consistency (coefficients of equivalence) and test-retest reliability (coefficients of stability). This …

Exploration Of Patient Variables And Characteristics Best Suited For Medical Marijuana Treatment For Anxiety And Depressive Disorders, Corey Gazoo

Dissertations

Individuals with posttraumatic stress, anxiety and depressive disorders are currently being prescribed medical marijuana as a treatment in many states across the United States. However, marijuana is still considered a schedule one narcotic by the Drug Enforcement Administration and federal government, which provides several barriers and challenges to conduct research such as approval from the U.S. Food and Drug Administration and following guidelines from the National Institute on Drug Abuse issued by the DEA. Additionally, individuals prescribed medical marijuana for mental health disorders are not always thoroughly instructed on the type of medical marijuana, the dosage, and how frequently to …

The Professional Struggles Of Contemporary Korean Women: Origins And Consequences Of The Glass Ceiling, Liat Miller

Master's Projects and Capstones

The status of women globally, though improved in recent decades, remains an unresolved issue. The labor market, in which women must contend with the glass ceiling phenomenon, is an indicative microcosmos of a larger issue—the persistence of discriminatory attitudes toward women. The case is even more profound in East Asian contexts, such as South Korea. The existing literature is limited and focuses on either specific aspects of the glass ceiling or particular industries in Korea. This paper explores the origins and interconnected causes of the glass ceiling in Korea, which include Confucian philosophy and values. Moreover, by analyzing testimonials of …

The Power Of Friendships: Associations Between Friendship Quality, Satisfaction, And Well-Being For Children With Autism Spectrum Disorder, Melanie S. Feldman

Graduate Doctoral Dissertations

Children with autism spectrum disorder (ASD) exhibit characteristic deficits in the social domain, which can interfere with their ability to form and maintain high quality relationships with their peers. Indeed, children with ASD are generally regarded as having lower quality friendships than typically developing (TD) children. However, based on a small emerging literature, children with ASD, despite reporting having lower quality friendships, indicate that they are satisfied with their friendships at similar levels to their TD peers. This apparent discrepancy between friendship quality and satisfaction for children with ASD as compared to TD children suggests that another factor may account …

How Competition Undermines Deterrence, Kayse Jansen

MSU Graduate Theses

The re-emergence of great power competition has brought with it a U.S. government-wide initiative to reclaim and strengthen advantage and influence across all elements of national power. Competition is considered necessary to secure American interests and protect the existing liberal international order, as well as uphold deterrence by enhancing the nation’s ability to impose costs and deny benefits. This view, however, neglects a critical factor in deterrence: the cost of restraint, which reflects the acceptability of the status quo. Paradoxically, the more successful the nation is at “competition,” the less likely it may be in important deterrence situations. Successful diplomatic …

Debt Delivered: The Predatory Inclusion Of A Rent-To-Own Chain In The Treasure Valley, Jeff Cates

Masters Theses

This thesis is a study of customers at a rent-to-own (RTO) firm in Boise, Idaho, where I worked and collected data for nearly three years. RTOs are companies that offer higher-end electronics, appliances, and furniture to customers on a contract where the consumer receives the product immediately and pays a (usually highly marked-up) price over time by making small weekly or monthly payments. While predatory lending practices have long been studied by scholars from various fields, very little work has focused on the rent-to-own industry, which may have unique differences from payday lending and other similar businesses. This thesis centers …

A Creative Path To Building A Labyrinth: A Reflexive Journey To A Wise And Compassionate Inner Life, Nicole S. Jones

Creativity and Change Leadership Graduate Student Master's Projects

The labyrinth, a unicursal walking path, can be found throughout the world. There is evidence of its existence as far back as c.1200 B.C. Since the late 90’s the labyrinth has re-emerged and grown in popularity in the western world as a spiritual and creative thinking tool. While more often establishing them on sites of spiritual, organizational and creative communities, some people have placed them on private property. The purpose of this research project is to understand the creative process of designing and constructing a labyrinth on private property. How might the creative person be impacted by an intrinsically motivated …

Exploring The Influence Of Gendered Racism On Salivary Alpha Amylase Activity Among Black Women, Erica J. Peppers

Doctoral Dissertations

This study tests Lewis and colleagues’ (2017) biopsychosocial model of gendered racism, which extends the biopsychosocial model of perceived racism (Clark et al., 1999) to gendered racism by investigating the role of gendered racial microaggressions (e.g., subtle gendered racism) in autonomic nervous system (ANS) dysregulation among Black women. Specifically, the association between the stress and frequency of gendered racial microaggressions and sAA activity, including total sAA output, diurnal slope, and waking sAA as indicators of ANS dysregulation were examined among Black women (N = 90, M_age = 19 years, SD = 5.02). Four types of gendered racial microaggressions unique …

Implicit Theories As A Moderator Between Religious Commitment And Forgiveness Among Muslims Experiencing A Religious Identity Offense., John Michael Hart Ii

Electronic Theses and Dissertations

A recurrent finding in the literature on the relationship between religion and forgiveness is that religious people tend to describe themselves as forgiving while reporting less forgiveness in response to actual offenses (Davis, Worthington, Hook, & Hill, 2013; McCullough & Worthington, 1999). Scholars have suggested moderating factors may explain this discrepancy (Worthington et al., 2010), though the existing literature has been criticized as limited because much of the research is based on Christian samples (Carlisle & Tsang, 2013; Davis et al., 2013). Implicit theories, which have previously been found to be associated with forgiveness and theorized to be related to …
