From Catching Up To Surpassing—A Multi-Case Study Of Chinese Latecomer Technology Firms, Baohua Chen

Dissertations and Theses Collection (Open Access)

In recent years, a number of Chinese latecomer technology firms have grown rapidly and, in some cases, have even moved into leading positions in global competition. As global competition is being reshaped, technologies are evolving more rapidly, and traditional catch-up paths are becoming less viable, how these Chinese latecomer technology firms catch up with leading incumbents has become an important issue in strategic management research. Drawing on the theoretical lens of asymmetrical competition, resource orchestration, and dynamic capabilities, this study adopts an Eisenhardt-style multiple-case design to conduct a longitudinal comparative analysis of six firms—Insta360, Dreame, DJI, Unitree, Transsion, and Royole—and …

Essays On Money Search Models, Fangfang Gong

Dissertations and Theses Collection (Open Access)

This dissertation comprises three papers that use money search models to revisit the distributional welfare costs of inflation, study the optimal design of a central bank digital currency (CBDC), and investigate the role of liquidity and monetary policy in initial investment and capital reallocation in secondary markets.

The second chapter develops a micro-founded general equilibrium model of payments to revisit the distributional welfare costs of inflation. We consider different cost structures incurred by merchants when accepting cash and deposits. In equilibrium, there exists a cutoff for buyers’ money holdings, above which card payments are accepted by merchants. We calibrate the …

Securing Cloud-Native Systems: From Vulnerability Analysis To External And Insider Threat Detection, Jiongchi Yu

Dissertations and Theses Collection (Open Access)

Cloud-native systems have become the backbone of modern software infrastructure. However, their dynamic resource orchestration and complex configurability introduce a large attack surface and intricate security challenges. Adversaries can externally exploit vulnerabilities in cloud components or perform insider movement within cloud environments to launch attacks. As these systems increasingly support critical services, security breaches can lead to severe operational and economic consequences.

Despite extensive efforts in vulnerability detection and attack monitoring, existing approaches struggle to remain effective in cloud-native environments characterized by rapid evolution and inherent heterogeneity. In particular, they exhibit three fundamental limitations: (1) Insufficient understanding of defect patterns …

Uncertainty, Information, And Major Choice: Evidence From Chinese Gaokao, Sikun Dou

Dissertations and Theses Collection (Open Access)

An unresolved background risk makes people more averse to other, independent  risks—most of all when a high-stakes, irreversible choice must be made under that risk. College major choice is such a setting. In China, students are admitted directly into a major they cannot easily change, and in the early 2000s they had to commit before learning their exam scores, bearing a field’s academic risk on top of an unresolved admission risk. Because STEM fields carry more academic risk and women are on average more risk-averse, this burden falls hardest on women’s entry into STEM. Exploiting a reform that moved application …

High-entropy carbides (HECs) are often treated as a single material class defined by configurational entropy; however, their properties are governed by composition-specific defects and grain-boundary chemistry. This study demonstrates that substituting a single element can qualitatively change grain-boundary structure and fracture behavior in HEC ceramics. Two HECs, (Cr,Hf,Ta,Ti,Zr)C (HEC-Cr) and (Hf,Ta,Ti,W,Zr)C (HEC-W), were examined via electron microscopy, atom probe tomography, and molecular dynamics simulations. Simulations predict preferential segregation of Cr, W, and Zr to grain boundaries. Experiments confirmed Cr enrichment at grain boundaries and the formation of W-rich nanograins along boundary networks. Mechanical testing revealed that these compositional differences translated …

In-Operando Imaging For Mechanistic Insights And Process Optimization In The Biofuel-Driven Combustion Synthesis Of Cement And Precursor Phases, Shubham Agrawal, Jeffrey J. Long, Aditya Kumar, Narayanan Neithalath

Materials Science and Engineering Faculty Research & Creative Works

Biofuel-based combustion synthesis (BCS) is a promising low-carbon pathway for decarbonizing cement production, providing an alternative to the fossil-fuel-driven clinkering process typically conducted at ∼1450 °C. Understanding microscale combustion mechanisms is essential to efficiently transfer biofuel-generated heat to cement precursors for targeted phase formation. Unlike previous studies focusing on macro-scale parameters such as fuel content/type, porosity, and holding temperature, this work provides mechanistic insights into microscale combustion behavior, linking microstructural phenomena with macro-scale processing conditions to guide parameter optimization. In-operando microscale imaging was employed to examine combustion wave propagation, spatio-temporal temperature evolution, and microstructural transformations within reactive pellets. Two combustion …

Strong And Ductile Additively Manufactured Ti-6al-4v Through Yttrium Inoculation, Saeid Alipour, Ji Young Kim, Min Seok Kim, Arezoo Emdadi, Ju Li

Materials Science and Engineering Faculty Research & Creative Works

The unique microstructural features and thermal cycles in alloys produced by additive manufacturing (AM) techniques have led to the emergence of a new paradigm in the design and development of alloys for performance-critical applications. Despite the inherent microstructural features of AMed parts, optimizing the porosity-microstructure while acquiring desired mechanical performance has been crucial yet challenging. Hence, in many legacy alloys, achieving a strength-ductility synergy in the as-built condition without applying post-heat treatment or hybrid processes is considered an arduous task. In this research, we aimed to tailor the microstructure of the legacy Ti-6Al-4V alloy in the as-built condition by implementing …

Post-Exercise Vitals Recovery Response In Barrel Horses: A Field Study On Cooling Methods Used By Competitors, Lauran E. Hetrick

Electronic Theses and Dissertations

Barrel racing demands peak physical performance from equine athletes, yet limited research evaluates the field-based strategies used to optimize equine recovery at competition. This study assessed recovery management approaches used by competitors to elucidate their influence of physiological recovery by measuring heart rate, respiratory rate, and body temperature during a high-profile barrel race competition. Physiological data were collected at baseline, immediately post-exercise, and during a 15–30-minute cooldown period to characterize recovery under real-world conditions. Significant increases in HR, RR, and BT occurred from baseline to post-run (p < 0.001), followed by reductions during cooldown (p < 0.01), though values remained elevated (p < 0.05). Rinsing reduced HR and RR (p < 0.01), while shade and fans decreased RR and variably influenced HR. Noise, as a confounding variable, decreased HR but increased BT (p < 0.001). Ultimately, these results emphasize multimodal recovery approaches in competitive equine management in the field.

This thesis examines marches through the lens of Schenkerian analysis, which uncovers deep levels of structural cohesion and brings a fresh perspective to the American march genre. Specifically, this study uses Schenkerian methods to study the music of Karl L. King (1891-1971) across the span of his half-century career. King’s extensive output established an enduring blueprint for the genre. By applying an analytical framework derived from the work of Harald Krebs, this research demonstrates how the march can …

Bass And Drum Grooves In R&B: Analysis And Composition, Hugh Taylor

Electronic Theses and Dissertations

The term “R&B” has existed within the musical lexicon for nearly eighty years. It was first introduced in 1949 to replace the label “race music,” and was a combination of blues, jazz, gospel, and rock. Since then, the genre has transitioned from swing-based, live instrumentation toward straight-eighth backbeats and electronically produced sounds. Despite these shifts, contemporary R&B continues to borrow from its ancestral roots while maintaining a modern aesthetic. A primary feature that has persisted through this landscape is the “groove,” specifically defined here as the rhythmic layer created by the drums and bass. In R&B, the bass provides both …

Thinking Beyond Bias: The Confirmation Bias Index And The Cognitive–Motivational Predictors Of Accurate Headline Evaluation, Anthony Cantu

Electronic Theses and Dissertations

Confirmation bias — the tendency to favor belief-consistent information over contradictory evidence — represents a central challenge in contemporary misinformation research, yet its behavioral measurement has remained inconsistent across studies. This study introduced the Confirmation Bias Index (CBI), a preregistered behavioral measure defined as the difference in accuracy between ideologically congruent and incongruent headline evaluations. Using a 3 (headline slant: Conservative, Neutral, Liberal) × 2 (veracity: True, False) within-participants design, 198 participants evaluated 36 validated news headlines for accuracy. Results supported a veracity main effect and a reliable group-level confirmation bias effect indexed by the CBI. Headline slant alone did …

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …

Insolvency Law In The Global South: Lessons For The Global North, Aurelio Gurrea-Martinez

Research Collection Yong Pung How School Of Law

Despite the influence of the Global North in many insolvency laws and practices in the Global South, this article shows that the Global South has innovated in many aspects of insolvency law. In some cases, these innovations consist of solutions that, with certain adjustments, have been imported from the Global North. In others, they are really ‘autochthonous innovations’ from the Global South. This article identifies both types of innovations, providing examples from jurisdictions such as Brazil, Chile, China, Colombia, Dominican Republic, India, Malaysia, Mexico, Myanmar, Peru, Philippines, Thailand and Uruguay. More importantly, it will be shown how those innovations from …
