Rank-Guaranteed Auctions, Wei He, Jiangtao Li, Weijie Zhong

Research Collection School Of Economics

We propose a combinatorial ascending auction that is “approximately” optimal, requiring minimal rationality to achieve this level of optimality, and is robust to strategic and distributional uncertainties. Specifically, the auction is rankguaranteed, meaning that for any menu M and any valuation profile, the ex-post revenue is guaranteed to be at least as high as the highest revenue achievable from feasible allocations, taking the (|M| + 1)th-highest valuation for each bundle as the price. Our analysis highlights a crucial aspect of combinatorial auction design, namely, the design of menus. We provide simple and sufficient menus in various settings.

Reading The Candlesticks: An Ok Estimator For Volatility, Jia Li, Dishen Wang, Qiushi Zhang

Research Collection School Of Economics

We propose an Optimal candlesticK (OK) estimator for the spot volatility using high-frequency candlestick observations. Under a standard infill asymptotic setting, we show that the OK estimator is asymptotically unbiased and has minimal asymptotic variance within a class of linear estimators. Its estimation error can be coupled by a Brownian functional, which permits valid inference. Our theoretical and numerical results suggest that the proposed candlestick-based estimator is much more accurate than the conventional spot volatility estimator based on high-frequency returns. An empirical illustration documents the intraday volatility dynamics of various assets during the Fed chairman's recent congressional testimony.

Migrants As Sustainability Actors: Contrasting Nation, City And Migrant Discourses And Actions, Claudia Fry, Emily Boyd, Mark Connaughton, Neil W. Adger, Maria Franco Gavonel, Caroline Zickgraf, Sofia Fransen, Dominique Jolivet, Anita Fábos, Ed Carr

Sustainability and Social Justice

Although it is widely recognized that migration is socially transformative, the potential contributions of migrants to transformations towards sustainability in their destination areas are often overlooked in mainstream discourse on environmentalism and sustainability. Here we seek to identify current narratives of migrants and sustainability across individual, urban, and national scales. Migrants are commonly framed in public policy as having no or even negative impacts on sustainability. The study hypotheses that the lived experience of sustainability by migrants within urban destinations differ from dominant discourses and perceptions of migrant populations within societies. We test and document such divergence using data from …

Exploring Performance-Based Contracts: A Good Option To Address Long-Term Road Maintenance In California?, Maria Calahorra-Jimenez, Richard Poythress

Mineta Transportation Institute

Performance-based contracts (PBCs) used in road maintenance provide flexibility for considering new materials, design, and technology to achieve predetermined performance targets. Several states in the U.S. have already used these types of contracts in road maintenance, and their experience can inform the use of PBCs in California. The objectives of this research are twofold. First, identify the benefits and challenges of PBCs compared to traditional contracts. Second, explore the main aspects of PBCs implementation for road maintenance and relate them to California's context. To this end, deductive-inductive content analysis was conducted on 84 peer-reviewed articles published between 1998 and 2023. …

The project revealed several …

Experimental Investigation Of The Self-Healing Potential Of Bacteria For Sustainable Concrete Structures Phase 2, Andrea Calabrese, Pitiporn Asvapathanagul, Nisarg N. Patel, Nanubala Dhruvan, Austin Adams, Michael Hernandez, Douglas S. Lopez-Cruz

Mineta Transportation Institute

Concrete is a critical component of so much of the modern construction industry. This material, well known for its versatility, robustness, longevity, and strength, is well-suited for a wide range of structural applications. Nonetheless, the widespread occurrence of cracks in concrete structures, primarily attributed to its limited tensile strength, shrinkage, and overstain, imposes a considerable economic and environmental challenge when it comes to retrofitting these fissures. This study tackles this problem by harnessing bacteria tolerant to high alkaline conditions to enable Microbially Induced Calcium Carbonate Precipitation (MICP) for the self-repair of concrete. This is achieved through an external application method, …

Battery Management System Development For Electric Vehicles And Fast Charging Infrastructure Improvement, Yu Yang, Hen-Geul Yeh, Cesar Ortiz

Mineta Transportation Institute

The electric vehicle (EV) has become increasingly popular due to its being zero-emission. However, a significant challenge faced by EV drivers is the range anxiety associated with battery usage. Addressing this concern, this project develops a more efficient battery management system (BMS) for electric vehicles based on a real-time, state-of-charge (SOC) estimation. The proposed study delivers three modules: (1) a new equivalent circuit model (ECM) for lithium-ion batteries, (2) a new SOC estimator based on the moving horizon method, and (3) an on-board FPGA implementation of the classical Coulomb counting method for SOC estimation. The research team extends the traditional …

Spatio-Temporal Analysis Of The Roadside Transportation-Related Air Quality (Startraq 2022): Data-Driven Exposure Analysis By Transportation Modes, Jaymin Kwon, Yushin Ahn, Steve Chung

Mineta Transportation Institute

Particulate matter (PM) pollution poses significant health risks, influenced by various meteorological factors and seasonal variations. This study investigates the impact of temperature and other meteorological variables on PM10 and PM2.5 levels in Fresno County, known for high air pollution. Multiple linear regression (MLR) and generalized additive models (GAMs) assess the significance of these relationships. Analyzing data from Fresno County, we examine PM10 and PM2.5 levels across "hot" (June to August) and "cool" (September to May) seasons. Findings indicate PM10, both MLR and GAM models identify statistically significant variables, excluding temperature and wind direction in each season. However, during the …

Childhood Maltreatment And Amygdala-Mediated Anxiety And Posttraumatic Stress Following Adult Trauma, Farah Harb, Michael T. Liuzzi, Ashley A. Huggins, E. Kate Webb, Jacklynn M. Fitzgerald, Jessica L. Krukowski, Terri A. Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background

Childhood abuse (physical, emotional, and sexual) is associated with aberrant connectivity of the amygdala, a key threat-processing region. Heightened amygdala activity also predicts adult anxiety and posttraumatic stress disorder (PTSD) symptoms, as do experiences of childhood abuse. The current study explored whether amygdala resting-state functional connectivity may explain the relationship between childhood abuse and anxiety and PTSD symptoms following trauma exposure in adults.

Methods

Two weeks posttrauma, adult trauma survivors (n = 152, mean age [SD] = 32.61 [10.35] years; women = 57.2%) completed the Childhood Trauma Questionnaire and underwent resting-state functional magnetic resonance imaging. PTSD and anxiety …

Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young

Research Collection School of Social Sciences

The expanding footprint of urban Asian settlements and increasing living standards have put pressure on cemetery sites. Public health narratives and the sanctity associated with death matters in Asian urban landscapes have fed into the rhetoric of cemeteries as undesirable heritage spaces. Often lacking protection, many cemeteries have been exhumed, cleared, and relocated to allow room for new developments and infrastructure, risking the survival of this quiet element of the urban cultural patrimony. Within an Asian context, synergies between nature and cultural heritage preservation are not prevalent in major cities like Singapore, Hong Kong, Tokyo, Manila, Kuala Lumpur, and Bangkok. …

Gamified Bodies And The Illusory Meaning Of Muscle, Orlando Woods

Research Collection College of Integrative Studies

This paper foregrounds the agency of the body to explore how it is “gamified” in the pursuit of a desired self-image. Gamified bodies are those that are tricked into metabolising in ways that suit the representational aspirations of the self. The aspirations that I consider in this paper are those of muscle, and how individuals trying to build muscle pursue various metabolic tricks to try and overcome, or otherwise suppress, the in-built agency of the body. Exploring and understanding these tricks contributes to feminist understandings of the body generally, and of muscle specifically, and its unruly nonconformity to the gendered …

Insourcing The Smart City: Assembling An Ideo-Technical Ecosystem Of Talent, Skills, And Civic-Mindedness In Singapore, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article examines an alternative model of smart city formation, one based on the principle of insourcing technical competencies and capabilities to those responsible for city governance. This model counters the logic of technological outsourcing upon which many assumptions and critiques of the smart city rest, and thus reveals ways in which a more generative discourse can be forged. Drawing on a series of in-depth interviews with senior stakeholders from public and private sector organizations, we develop a case study of Singapore’s Smart Nation initiative. Through coordinated efforts to reorganize the public sector’s technological functions, develop nation-wide skills upgrading programs, …

Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford

Research Collection College of Integrative Studies

Urban areas in hot and humid tropical regions are frequently exposed to uncomfortable thermal levels. A well-developed urban heat mitigation strategy is increasing vegetation infrastructure, even though the impact differs based on regional climate. In this study we have evaluated the impact of rainfall on air temperature, humidity and thermal comfort inside a large urban park in Singapore, based on measurement campaigns. A comparison between the park and an urban site is presented. Results show that rainfall significantly reduces air temperature and improves thermal comfort levels, not only right after the rain event but also in the after-event dry period. …

Of Light And Shadows: Buddhism, Cinema, And The Question Of Diffused Religion In Modern China, Teng-Kuan Ng

Research Collection College of Integrative Studies

While the scholarship on premodern Chinese Buddhism has explored the tradition’s rich diffusion throughout various realms of sociocultural life, the study of modern Chinese Buddhism leans heavily towards its monastic, institutional, and overtly “religious” forms. This split mirrors the logic of modern secularization, whereby religion should be rationally differentiated from the broader social fabric, institutionalized, and delimited within its own discrete functional sphere. This article rethinks the putative rupture between Chinese Buddhism’s past and present incarnations. Through the prism of cinema, a technology that arrived on Chinese shores at the same moment as the Western concept of religion, I illuminate …

Cash, Crowds, And Cooperation: The Effects Of Population Density And Resource Scarcity On Cooperation In The Dictator Game, Tan Kai Lin, Lynn, Norman P. Li, Kenneth Tan

Research Collection School of Social Sciences

The adaptive benefits of cooperation among humans have been widely studied. However, is being cooperative always adaptive across various combinations of ecological conditions? Existing work has focused on cultural, inter-, and intra-individual predictors of cooperation yet there is a lack of research on how an individual's ecology may come into play. In this work, we focus on the interaction of two ecological factors—population density and resource scarcity—on cooperation. Population density is often accompanied by social competition for limited resources. We hypothesise that in response to cues of high (versus low) population density, people facing resource-scarcity would adaptively lower their cooperativeness, …

Relationship Commitment Regulation: Influencing A Partner's Commitment To Achieve One's Commitment Goals, Laura V. Machia, Kenneth Tan, Christopher R. Agnew

Research Collection School of Social Sciences

We introduce a model of relationship commitment regulation, which describes how romantic partners might use empirically-validated antecedents of commitment level strategically to influence a partner's commitment toward their relationship based on certain commitment goals they have for the relationship. People are generally aware of and relatively accurate with respect to knowing their partner's level of commitment and also have preferences regarding their desired level. We summarize key antecedents of commitment level (i.e., satisfaction level, alternative quality, investment size, future plans, and subjective norms) and then describe how each can be manipulated via relationship maintenance activities to move a partner's commitment …

Hot At The Top: The Influence Of Self-Rated Attractiveness On Self-Perceived Status, Lynn K. L. Tan, Michal Folwarczny, Tobias Otterbring, Norman P. Li

Research Collection School of Social Sciences

Beautism reflects the phenomenon of a widespread positivity bias that physically attractive people enjoy. This bias results in more attractive people receiving more positive social judgments, interactions, and economic outcomes. However, the literature has largely focused on third-party judgments of physical attractiveness, neglecting examinations of how self-rated attractiveness may predict self-evaluations. We sought to address this gap by examining how self-rated attractiveness predicts self-inferred social status, which is related to a myriad of psychosocial outcomes. Across one pilot test, one cross-sectional study, and a between-subjects experiment, we find converging evidence for the notion that self-rated physical attractiveness positively predicts higher …

Broken Kinship: Family Property Disputes And The Common Intention Constructive Trust In Singapore, Hang Wu Tang

Research Collection Yong Pung How School Of Law

There has been a proliferation of common intention constructive trust claims in Singapore. The main reason is that families have acquired real estate using their collective earning power without explicitly considering the individual entitlement of each family member. When a dispute arises, the claim is often pleaded as a common intention constructive trust. The complication with applying the law on the common intention constructive trust is that this is an English doctrine developed to deal with a different social context i.e. the breakdown of the relationship between cohabiting couples. In Singapore, the common intention constructive trust applies primarily in a …

Evaluating Urban Fire Vulnerability And Accessibility To Fire Stations And Hospitals In Austin, Texas, Akhil Mandalapu, Kijin Seong, Junfeng Jiao

Research Collection College of Integrative Studies

Anthropogenic climate change has increased the frequency and intensity of fires. Despite their widespread consequences, current research has largely overlooked urban fires and their associated vulnerability. This study seeks to identify patterns of fire vulnerability, map out areas with high fire vulnerability and limited access to fire stations and hospitals, and ultimately determine the factors contributing to increased fire incidents. Principal Component Analysis was used to develop a fire vulnerability index comprising variables capturing health status and socio-environmental factors. Enhanced 2-step floating catchment area (E2SFCA) analysis was conducted to determine relative accessibility to resources such as hospitals and fire stations. …

A New Look For Library Resources & Technical Services, Rachel E. Scott, Michael Fernandez

Faculty and Staff Publications – Milner Library

[In the absence of an abstract, the opening of the editorial is presented.]

Those of you who enjoyed the double issue on open access likely noticed that Library Resources and Technical Services (LRTS) articles have a new look. After years of maintaining its signature double-column layout, LRTS is now published in a single-column format. What prompted the change, you ask? A few months ago, a reader reached out to request that LRTS switch to a single-column format. The reader rightly noted that the change would improve the accessibility of the content. Specifically, the formatting issue relates to screen …

The Impact Of Emotional Impulsivity On Emotion Regulation And Internalizing Disorders: Competing Latent Path Models, Alicia L. Milam

Psychology Theses & Dissertations

Emotion regulation has been identified as a transdiagnostic risk factor in internalizing disorders. Previous literature has attempted to classify regulatory strategies by their temporal and functional characteristics to determine how to best implement emotion regulation interventions. However, these frameworks occasionally conflict, particularly in the presence of factors impacting regulatory strategy selection such as emotional impulsivity. This project examined competing theoretical models of emotion regulation strategy classification as related to internalizing psychopathology as well as explore the association between emotional impulsivity, regulatory classification and internalizing psychopathology. A community sample of 783 adults recruited through Amazon MTurk completed online questionnaires related to …

Testing A Model Of Ethnic/Racial Discrimination, Ethnic Identity, And Adult Attachment In College Students, Kenneth L. Ayers

Psychology Theses & Dissertations

Ethnic/racial minoritized Americans encounter a disproportionate amount of discrimination throughout their lifetime that often has negative effects on their well-being and mental health. Although the impact of discrimination on symptoms of depression and substance use has been widely studied, understanding of the mechanisms through which these associations exist are still largely unknown. From the perspective of the Cultural Development and Psychopathology Framework, the effects of discrimination on psychopathology (i.e., depression symptoms and alcohol use) are likely mitigated by normative developmental processes. One such developmental outcome that has been determined to partially mediate the impact of cultural stressors (i.e., ethnic/racial discrimination) …

States And Multi-Hazard Early Warning Systems, Faith N. Masibili

Graduate Program in International Studies Theses & Dissertations

The lack of early warning systems for half of the countries worldwide and poor investments in regulatory frameworks to link early warnings to emergency plans exacerbates the exposure of populations at risk of natural hazards in livable urban environments. This study hypothesizes that the level of democracy, trade openness, economic prosperity, per capita public aid, hazard exposure, lack of coping and adaptive capacities, classification as least developed countries (LDC), landlocked developing countries (LLDC), and small island developing States (SIDS), population in urban areas, cellular mobile, state fragility index, and regional vulnerability impact the efficiency of a country’s early warning system. …

Sexual Assault Disclosure: Understanding How The Reception Of Disclosure Effects Survivors’ Mental Health, Jade Buchanan

Undergraduate Theses and Capstone Projects

Sexual Assault is a rampant issue in the United States that affects Americans across race, gender, and lifespan. The United States’ continually fails to provide comprehensive physical and mental healthcare to Survivors post-assault. Survivors experience a lack of access to formal support systems and post-assault care that for Survivors of Sexual Assault could dramatically impact post-traumatic cognitions. Furthermore, there are several factors of a Survivors identity that interact with and shape their experience with these unique supports systems. The purpose of this research is to engage in a meta-analysis of how adult Survivors’ gender, race, support received, and experiences with …

Young Driver Training And Socioeconomic Status: A Human-In-The-Loop Driving Simulator Evaluation, Jeffrey Edward Glassman

Psychology Theses & Dissertations

Previous research consistently shows that young drivers are poor at anticipating latent hazards on the roadway compared to more experienced drivers. The Road Awareness and Perception Training (RAPT) program is a driver training program that aims to accelerate young drivers’ learning of hazard anticipation (HA) skills. More recent research has started showing evidence that RAPT may be even more effective at reducing accidents for young drivers with a lower socioeconomic status (SES), though the direct impact of RAPT on HA skills in the driver population is yet unclear. The current experiment thus directly evaluated the effectiveness of RAPT on the …

The Impact Of Peer Observational Learning On Honesty Following A Transgression, Hannah M. Sliman

Psychology Theses & Dissertations

Parents and teachers concerns about the development and socialization of lying aligns with research suggesting that persistent lying is related with delinquency, aggression, and conduct problems. We were interested in examining the difference between two groups: Honest and Praise (HP), and Control Group (CG) for the extent to which exposure to the experimental condition influenced a child’s decision to be honest and confess after a transgression. The study was designed to examine the extent to which observing peers of similar age receiving praise for being honest can promote honesty amongst children. Further, the study determined if gender influences honest reporting. …

Associations Between Combat Exposure, Moral Injury, And Suicidality Among U.S. Military Members: The Moderating Impact Of Positive Rumination, Jeffrey M. Gabelmann

Psychology Theses & Dissertations

Numerous studies have documented the risk for suicide among recent-era veterans with combat experience. Recently, moral injury has emerged as a possible contributor to suicidality in veterans. To that end, no study has approached the combat exposure-moral injury-suicidality link with a focus grounded in positive psychology. Specifically, the present study explored whether positive rumination, or the reflection on positive emotions and moods, may buffer the deleterious effects of potentially traumatic experiences in warzones on moral injury and suicidality. This study was a secondary analysis of 250 current or former U.S. military members (M_age = 33.3 years) who had …
