Mapping Horizon Limits Using Topographical Reference Points For Determining Pre-Columbian Circum-Caribbean Indigenous Interisland Contact Routes, Al M. Rocca

SSGS Faculty Publications and Presentations

Existing archaeological studies have suggested an extensive network of ongoing human travel operated between the Bahamas, the Greater Antilles, and the Lesser Antilles before and at the time of European contact in 1492. Additional evidence prompts some scholars to propose expanded contact of these areas with Mesoamerica, the rest of Central America, the northern coast of South America, and the Florida peninsula, resulting in an interconnected circum-Caribbean region. A variety of economic, political, and social influences stimulated this desire for sea and ocean movement, including migration, trading, tribute, raiding, and social connectedness. Geographic and oceanographic factors such as distance between …

Recusal Reform: Treating A Justice's Disqualification As A Legal Issue, Michael J. Broyde, Hayden H. Hall

Faculty Articles

This article addresses the pressing issue of recusal in the U.S. Supreme Court. It critiques the current practice of Supreme Court Justices deciding individually whether to recuse themselves from cases, highlighting the flaws and potential biases inherent in this practice. The authors advocate for a reform where initial recusal decisions are made by individual Justices but then are subject to review by the Supreme Court as a whole.

The article offers several arguments to support this proposal. First, the authors explore the evolution of recusal laws, focusing on the significant amendments to 28 U.S.C. § 455 in 1948 and 1974. …

The Interplay Of Morality, Emotional Labor, And Customer Injustice: How Salesperson Experiences Shape Job Satisfaction, Omar S. Itani, Colin B. Gabler, Ashish Kalra, Khashayar Afshar Bakeshloo (Kash), Raj Agnihotri

Marketing Faculty Publications

Despite the significant role emotions play in business-to-business (B2B) sales transactions, the impact of salesperson emotional labor on well-being, specifically job satisfaction, has garnered limited attention. To address this gap, the present study examines the relationships among salesperson moral identity, emotional labor strategies, customer injustice, and job satisfaction. An analysis of responses from B2B salespeople reveals that moral identity internalization is positively related to deep acting and negatively to surface acting, whereas moral identity symbolization is positively related to both deep and surface acting. Furthermore, surface acting has a stronger unfavorable effect on customer injustice compared to deep acting, which …

Legislatures And Localized Resentencing, Ronald F. Wright, Kay L. Levine

Faculty Articles

Recent legislation, exemplified in statutes from California and Washington, creates new methods for resentencing defendants in old cases. These laws place controlling authority for resentencing in the hands of local officials, especially local prosecutors, and invite variation at the county level.

While some new procedural channels for reducing the sentences of people convicted of past crimes are mandatory, in that they entitle certain defendants to resentencing if they were convicted of certain crimes or were subject to certain penalty enhancements that are no longer valid, other statutes create discretionary resentencing channels. In the discretionary channels, the chief local prosecutor has …

Federalism, State Action, And Workers’ Medical Privacy, Ani B. Satz

Faculty Articles

Injured workers entering state workers’ compensation systems effectively forego their medical privacy. This is due to widespread judicial misinterpretation of the HIPAA Privacy Rule (HPR) as excluding injured workers from federal medical privacy protections. As a result, medical privacy for workers’ compensation claims is effectively governed by state law. This Article argues that states have failed to protect the medical privacy of injured workers adequately and that there is a pressing need for legislative reform. The Article presents the first comprehensive survey in the legal literature of state action protecting the medical privacy of injured workers. Part I describes the …

Super-Groups: Legal Empowerment And “Public Law”, Matthew B. Lawrence

Faculty Articles

Not all interest groups are created equal. Some groups are created by or with the help of law. Law can confer political power on groups through wealth, rents, concentrated interest, and durability, creating synthetic factions that use their state-given influence to dominate lawmaking. Deregulatory and progressive traditions in public law have long thought differently about laws that empower. A deregulatory tradition sees legal empowerment as a democratic pathology that counsels against lawmaking, citing empowerment concerns as a perennial rhetorical point against consumer protection, environmental protection, and social welfare programs, among others, for fear they will lead to “capture.” At the …

Federal Officer Criminal Case Removal, Jonathan R. Nash

Faculty Articles

Recent events have brought the federal officer removal statute to the fore. The statute allows a defendant to remove a criminal prosecution to federal court, provided that the allegedly criminal behavior was performed by the defendant as a federal officer under color of office and provided that the defendant has a federal defense. Current litigation has exposed several open, important questions under the statute, which this Article confronts. On the question of who qualifies as an “officer” who can remove under the statute, it argues that removal is available both to former officers and to presidents. On the question of …

Katz'S Imperfect Circle: An Empirical Study Of Reasonable Expectations Of Privacy, Tonja Jacobi, Christopher Brett Jaeger

Faculty Articles

Under Katz v. United States, the Fourth Amendment restricts government actions that infringe upon expectations of privacy that society recognizes as reasonable. This foundational test has long been criticized as circular, both because courts can shape the very expectations they seek to identify through their decisions and because governments can manipulate those expectations to expand the reach of their own power. But how do members of society decide what expectations are reasonable, and how do judges ascertain those expectations? And are expectations of privacy malleable even without deliberate manipulation?

This Article shows that the circularity critique is both understated …

Vice Capital, Andrew K. Jennings, Kimberly D. Krawiec

Faculty Articles

Academic and market interest in environmental, social, and governance (ESG) investing has grown markedly in recent years. Although less prominent, a substantial literature also explores whether “sin pays” in the public capital markets. This literature’s underlying theory is that social norms discourage the funding of businesses that promote vice. According to this theory, some investors—particularly institutions sensitive to social norms, such as pension funds and foundations—will shun vice investments. A consequence of this aversion is a “vice premium” for those investors who will invest in such companies. Largely unexplored, however, is what industries or business models qualify as “vice,” how …

Tort Liability For Failure To Age Gate: A Promising Regulatory Response To Digital Public Health Hazards, Matthew B. Lawrence, Brett Frischmann, Avi Sholkoff

Faculty Articles

Tort liability for failure to “age gate” is a promising legal response to the public health hazards of AI, social media, sports gambling, and other digital spaces. Tort liability for failure to “age gate” hinges liability for harms to minors on an app’s failure to take reasonable steps to prevent minors from gaining access or otherwise to apply appropriate governance rules, such as privacy-protective default settings or ensuring genuine parental consent. While no one legal response is a panacea, tort liability for failure to age gate carries several distinctive advantages that make it a particularly promising option at this stage …

Searching For A Big Score: Analyzing Drug Yield From Search Warrant Executions, Elizabeth Griffiths, Walter Campbell, Kay L. Levine, Joshua C. Hinkle

Faculty Articles

In this study, we investigated the extent to which law enforcement efforts predicted drug and other kinds of illicit yield in search warrant executions. The data are drawn from one major metropolitan police department during 2005, 2009, and 2012. Using multilevel random intercept logistic regression models and multilevel random intercept multinomial logistic regression models, we regress high yields of various kinds of drugs and other illicit items seized during searches on the investigative activities that led to search warrant applications and the enlistment of teams of officers or other agencies in executing the search. Investments in high-effort search warrant work …

Defederalizing Opioid Addiction Care, Matthew B. Lawrence

Faculty Articles

Lack of access to evidence-based care for drug addiction is an urgent problem amid a decades-long overdose crisis that kills tens of thousands of Americans a year. Opioid addiction is the primary driver of overdoses today, and medicines exist to treat such addiction that can dramatically improve quality of life while reducing the risk of deadly overdose by more than half. Yet fewer than one in four of the nine million Americans who need such evidence-based medical care for their addiction receive it. Chief among barriers to access are restrictive and burdensome federal requirements limiting the use of narcotic medications …

Epilepsy: Etiology And Treatment Methods, Avital Nightingale

Epilepsy is a common neurological disorder that is caused by abnormal electrical activity in the brain. Due to the evolution of our understanding of epilepsy and its causes, a variety of therapeutic options have been developed to modulate seizures and limit their occurrence rate. Medication, diet and surgery have been the traditional treatments offered to individuals suffering from epilepsy but the latest advancements in neurotechnology have given patients with drug resistant epilepsy hope by providing options other than surgery. While the disorder is a complex one and its pathogenesis not yet fully understood, recent research has provided insight into the …

Limb Regeneration In Amphibians & Mammals, Jacob Mamrout

The Science Journal of the Lander College of Arts and Sciences

This thesis will give an in-depth analysis into the mechanisms of regeneration that amphibians use and how the blastema forms. It will also discuss genes and proteins that play a role including the P53 gene, Transforming Growth Factor Beta, CD59, and others. Regenerative potential of mammals will be discussed using the information found. Findings include that mammals may have regeneration potential because of the ability we have to deactivate certain genes to allow cells to dedifferentiate.

Gut Microbiome Dysbiosis And Its Contribution To Carcinogenesis, Daphne Grabie

The Science Journal of the Lander College of Arts and Sciences

The gut microbiome, a diverse community of microorganisms within the gastrointestinal (GI) tract, plays a pivotal role in maintaining health through digestion, immune regulation, and homeostasis. Emerging evidence links gut microbiome dysbiosis—a disruption in its composition and function—to the development and progression of various cancers, particularly within the GI tract. This review explores the multifaceted relationship between the gut microbiome and carcinogenesis, highlighting key microbial mechanisms, including chronic inflammation, production of carcinogenic metabolites, and immune modulation. Specific pathogens such as Fusobacterium nucleatum, Escherichia coli, and Helicobacter pylori are implicated in colorectal, gastric, and esophageal cancers, respectively, through pathways that promote …

Novel Pharmacotherapies For Treatment-Resistant Depression: Lysergic Acid Diethylamide (Lsd), Eliana Cohen

The Science Journal of the Lander College of Arts and Sciences

Treatment Resistant Depression has become extremely prevalent with 30% of depression cases being unresolvable. Psychedelics specifically Lysergic Acid Diethylamide has been a newfound unconventional approach that has demonstrated significant benefits for depression. LSD is a hallucinogenic drug mainly acting on the serotonin receptors that leads to altered sensory and perception affecting mood. This research paper comprehensively examines animal and human studies on LSD’s healing properties and enduring effects. The studies find that LSD induces neuroplasticity, and alters gene expressions associated with synaptogenesis and neurogenesis. Additionally LSD affects the activity of different neurotransmitters in the central nervous system enhancing mood. Lastly …

Factors Mediating The Reproductive Risk For Balanced Chromosomal Translocation Carriers, Talia Alter

The Science Journal of the Lander College of Arts and Sciences

Reciprocal balanced translocations occur when one part of a chromosome is exchanged with another, resulting in zero net loss of genetic material. While individuals with a balanced translocation are phenotypically normal, a translocation can cause increased risk of infertility, recurrent pregnancy loss, and the birth of a child with unbalanced chromosomes. In order to adequately guide an individual in their reproductive decisions, geneticists must be able to assess the risk of the patient’s unique translocation. An analysis of three recent studies reveals several factors which play a role in mediating the effects of balanced translocations and directly affect reproductive risk …

Environmental Racism In America: Minority Communities As Dumping Grounds For Environmental Waste, Shelly Taylor Page, Patricia A. Broussard

Southern Illinois University Law Journal

This Article explores the systemic and disproportionate burden of environmental hazards placed on minority communities in the United States. It examines the historical and contemporary practices of environmental racism, where Communities of Color, particularly Black, Indigenous, and Latino populations, are more likely to live in areas with high levels of pollution, hazardous waste sites, and industrial facilities. The Article highlights the intersection of race, class, and environmental policy, showing how socio-political and economic factors contribute to the marginalization of these communities. It underscores the urgent need for comprehensive policy changes that address the immediate health risks and the long-term environmental …

Evaluation Of Blending Ability Of Single-Shade Composite Relating To Different Cavity Depths And Abrasive Wear From Toothbrushing, Nattaporn Verayangkura

Chulalongkorn University Theses and Dissertations (Chula ETD)

Materials and Method: Eighty extracted human premolars were used for the shade‑matching evaluation. The materials tested in this study were Omnichroma (OC), Vittra APS Unique (VU), Charisma Diamond One (CD), and Filtek Z350 XT (FZ, control). The initial tooth shade was determined using a dental spectrophotometer and the reference color parameters (L, C, and H) were recorded with a laboratory spectrophotometer. A 4‑mm‑diameter cylindrical cavity was prepared in each tooth at restoration depths of either 1 mm or 2 mm. The prepared teeth in each restoration depth group were further divided into four subgroups based on the resin composite material …

Cumulative Environmental Impacts In Thailand : A Legal Appraisal Of The Eia Regime Under Neqa, Leila Kenza Cherkaoui

Chulalongkorn University Theses and Dissertations (Chula ETD)

This Research examines the limitations of Thailand’s Environmental Impact Assessment (EIA) framework under the Enhancement and conservation of National Environmental Quality Act B.e. 2535 (1992) (NEQA), with a focus on its failure to address cumulative environmental impacts in tourism-intensive regions such as Phuket, Koh Samui, and Chiang Mai. While EIA was originally introduced to ensure that environmental risks are considered before project approval, in practice Thailand’s system remains narrowly projectbased, overlooking the combined effects of multiple small and medium scale development that together exceed ecological carrying capacity. This has contributed to serious environmental degradation, including coral reef decline, freshwater depletion, …

Governance Rating Disagreement And Earnings Management In Asean Listed Firms, Pawat Dumrongkiate

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study investigates the relationship between corporate governance ratings and earnings management among publicly listed firms across six ASEAN countries—Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam—during the period 2015–2023. It examines whether the coverage, level, and disagreement of governance ratings influence the degree of discretionary accruals, which are used as a proxy for earnings management. The Modified Jones Model and Kothari’s performance-matched approach were employed to estimate discretionary accruals, with firm, country, industry, and year fixed effects applied to control for unobserved heterogeneity. The results reveal that governance rating coverage and overall rating levels do not significantly affect earnings …

The Moderating Role Of Investor Sentiment Regimes On The Impact Of Flow Types On Capital Structure Decisions (Evidence From Thailand), Shiva Sachaphimukh

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study analyzes how foreign and domestic capital flows influence the leverage of SET100 Thai non-financial firms, considering investor sentiment regimes and firm cyclicality (2013–2023). It contrasts fundamental foreign portfolio flows with speculative domestic trading turnover. Sentiment regimes powerfully amplify flow effects. Bullish domestic sentiment and high domestic turnover significantly increase leverage (sentiment-exploitation). Conversely, deteriorating sentiment and foreign outflows intensify debt reliance (stress-compensation). Domestic flows have stronger, more immediate leverage effects than foreign flows, revealing a behavioral asymmetry. Cyclical firms respond aggressively to domestic factors and sentiment, while non-cyclical firms prioritize foreign capital stability.The findings highlight the critical role of …

High-Yield Or Nothing? Investor Preferences For Riskier Bonds In Thailand, Thamon Chongkwanyuen

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study investigates the determinants of investor demand for high-yield corporate bonds in Thailand's primary market between 2014 and 2024, focusing on whether investors exhibit reach-for-yield behavior and how they respond to past issuance patterns. Utilizing panel regression, with the Take-Up Ratio serving as the key measure of investor participation, the findings reveal that investor behavior is highly conditional. In normal or tightening monetary periods, high nominal yields and credit spreads are generally associated with lower subscription rates, suggesting investors interpret elevated returns as a signal of greater credit risk. However, this risk aversion is reversed during accommodative monetary conditions …

Salience, Trading Volume And 52-Week High Effects On Stock Returns: Evidence From Thai Stock Market, Tonnsaai Anantrechai

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study examines the interaction between salience effects and the 52-week high phenomenon in the Thai stock market, with particular attention to the mediating role of trading volume. Using data from SET100 constituents spanning May 2005 to December 2024, we employ the salience measure developed by Bordalo et al. (2012) and Cosemans and Frehen (2021) to investigate whether stocks with salient payoffs exhibit different return patterns when approaching their 52-week highs. Following Lin (2024), we test whether abnormal trading volume amplifies these behavioral effects. Our findings reveal a notable discrepancy: while historical portfolio sorts show extreme return differentials between salience …

Passengers’ Perceptions, Attitudes, And Willingness To Fly With Southeast Asian Low-Cost Carriers During Routine Disruption Communication, Aqilah Filzah Binti Ahmad Ridwan

Chulalongkorn University Theses and Dissertations (Chula ETD)

The objective of this research was to examine how passengers perceive crisis communication during routine operational disruptions (RODs) within Southeast Asian low-cost carriers (LCCs), and to determine whether perceived communication quality predicts passenger attitudes and willingness to fly. This study also aimed to assess the relationship between passengers’ attitudes toward airlines’ disruption management and their subsequent willingness to fly after experiencing RODs. A total of 201 respondents who had previously flown with LCCs completed an online self-administered questionnaire. Simple linear regression analyses revealed that perceived crisis communication had a significant positive effect on passengers’ attitudes toward disruption management. Attitude, in …

Framed by influencer marketing strategy, framing theory, and the source credibility model, the research explores how influencers navigate authenticity, credibility, and identity while promoting domestic brands amid the “empty void” left by the scarcity of foreign products. Using purposive sampling, semi-structured in-depth interviews were conducted with five Myanmar-based food influencers active on Facebook and Tik Tok. Thematic analysis revealed that influencers strategically construct authenticity through personal brand alignment, …

The Influence Of Butterbear Mascot Attractiveness On Brand Attitude, Huyen Phuong Do

Chulalongkorn University Theses and Dissertations (Chula ETD)

This research examines the influence of mascot’s perceived attractiveness on the brand attitude towards Butterbear. Data were collected via online survey from 220 male and female respondents (aged 18-26) residing in Bangkok, who had been exposed to content from Butterbear brand within the past three months. Overall, participants perceived Butterbear mascot as highly attractive (M = 4.39) and reported positive attitudes towards the Butterbear brand (M = 4.30). Furthermore, the findings revealed that all six dimensions underlying mascot attractiveness (Brand Impact, Brand Expertise, Mascot Uniqueness, Mascot Anthropomorphism, Mascot Intimacy, and Mascot Consistency) showed statistically significant correlations with the brand attitude. …

Neural-Network Based K-Value Prediction In Clustering Problems Without Distance Computation, Rohhan Rabari

Chulalongkorn University Theses and Dissertations (Chula ETD)

Clustering remains a pivotal component of unsupervised learning, central to tasks such as data exploration and pattern discovery. However, most conventional clustering algorithms are parametric in nature, requiring one or more parameters to be specified in advance—most notably the number of clusters (k). These predefined parameters can drastically alter the outcome of clustering, leading to unstable or misleading results, particularly when the true structure of the data is unknown. This thesis introduces a novel framework that transforms raw input into a latent vector representation, enabling a neural network to automatically predict the optimal number of clusters without any prior parameter …
