Upper Plate And Subduction Interface Deformation Models In The 2022 Revision Of The Aotearoa New Zealand National Seismic Hazard Model, Russ J. Van Dissen, Kaj M. Johnson, Hannu Seebeck, Laura M. Wallace, Chris Rollins, Jeremy Maurer, Matthew C. Gerstenberger, Charles A. Williams, Ian J. Hamling, Andrew Howell, Christopher J. Dicaprio

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

As part of the 2022 revision of the Aotearoa New Zealand National Seismic Hazard Model (NZ NSHM 2022), deformation models were constructed for the upper plate faults and subduction interfaces that impact ground-shaking hazard in New Zealand. These models provide the locations, geometries, and slip rates of the earthquake-producing faults in the NZ NSHM 2022. For upper plate faults, two deformation models were developed: a geologic model derived directly from the fault geometries and geologic slip rates in the NZ Community Fault Model version 1.0 (NZ CFM v.1.0); and a geodetic model that uses the same faults and fault geometries …

Retardation Effects In Atom-Wall Interactions, T. Das, C. A. Ullrich, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

The onset of retardation effects in atom-wall interactions is studied. It is shown that the transition range from the 1/z3 short-range (van der Waals) interaction to the 1/z4 long-range (Casimir) retarded interaction critically depends on the atomic properties and on the dielectric function of the material. For simple non-alkali-metal atoms (e.g., ground-state hydrogen and ground-state helium) interacting with typical dielectric materials such as intrinsic silicon, the transition to the retarded regime is shown to proceed at a distance of about 10 nm (200 Bohr radii). This is much shorter than typical characteristic absorption wavelengths of solids. Larger transition regimes are …

Integrating Interference Theory, Daiquiri J. Steele

Articles

Robust retaliation protections are an essential component of any effective enforcement regime. Recognizing this, Congress has included a provision prohibiting retaliation in nearly every workplace statute passed in the past century. In statutes more than a century old, like the Civil Rights Act of 1866, where Congress neglected to include an explicit anti-retaliation provision in the statutory language, the Supreme Court has found an implied proscription against retributory behavior. Anti-retaliation protections are undoubtedly integral to effective enforcement. However, they have an equally important counterpart that is often overlooked in compliance discussions-interference protections.

Several workplace statutes contain interference provisions-statutory language that …

The Administrative State, Financial Regulation, And The Case For Commissions, Kathryn Judge, Dan Awrey

Faculty Scholarship

Administrative law is under attack, with the Supreme Court reviving, expanding, and creating doctrines that limit the authority and autonomy wielded by regulatory agencies. This anti-administrative turn is particularly alarming for financial regulation, which already faces enormous challenges stemming from the dynamism of modern finance, its growing complexity, and fundamental contestability. Yet that does not mean that defending the current regime is the optimal response. The complexity and dynamism of modern finance also undercut the efficacy of established administrative procedures. And the panoply of financial regulators with unclear and overlapping jurisdictional bounds only adds to the challenge. Both these procedural …

Reports, Projects, and Research

This review attempts to prepare the Homeland Security Enterprise for the impending use of AI in generation of novel and malign threats.

AI broadly refers to technology that can infer patterns from external data sources with numerous subfields including machine learning, logical agents, generative AI, and robotics.

The benefits of AI may be overshadowed by potential harms such as AI-based autonomous weaponry and malign AI interferences such as disruption of political information integrity.

The intersection of artificial intelligence and malevolent creativity involves using technology to generate and implement novel ideas to cause harm.

Cross-Border Technology Investments In Recession, Juliana Yu Sun, Huanhuan Zheng

Research Collection School Of Economics

Utilizing industry-level foreign direct investment (FDI) from 72 source markets to 122 destination markets between 2003 to 2018, we evaluate how cross-border technology investments respond to economic recessions. We find that FDI embedded with intensive research and development (R&D) drops when the destination market is in a recession and the source market is in a normal state and recovers to the pre-recession levels when both destination and source markets are in recession. However, there is little evidence that recessions affect cross-border investments in other aspects of technology measured by the penetration of robots, intellectual property products and information and communications …

Dl-Drl: A Double-Level Deep Reinforcement Learning Approach For Large-Scale Task Scheduling Of Multi-Uav, Xiao Mao, Guohua Wu, Mingfeng Fan, Zhiguang Cao, Witold Pedrycz

Research Collection School Of Computing and Information Systems

Exploiting unmanned aerial vehicles (UAVs) to execute tasks is gaining growing popularity recently. To address the underlying task scheduling problem, conventional exact and heuristic algorithms encounter challenges such as rapidly increasing computation time and heavy reliance on domain knowledge, particularly when dealing with large-scale problems. The deep reinforcement learning (DRL) based methods that learn useful patterns from massive data demonstrate notable advantages. However, their decision space will become prohibitively huge as the problem scales up, thus deteriorating the computation efficiency. To alleviate this issue, we propose a double-level deep reinforcement learning (DL-DRL) approach based on a divide and conquer framework …

Meaningful Work And Job Burnout Among Frontline Employees Of Classified Hotels In Nairobi City County, Kenya: Does Gender Identity Matter?, John Kahuthu Gitau, Rosemarie Ayuma Khayiya, Vincent Nyamari Maranga

Journal of Global Hospitality and Tourism

This study investigates the impact of meaningful work on job burnout (JBO) among frontline employees in Nairobi City County. Data was collected from 309 employees in various hotel categories ranging from two- to five-star-rated hotels. The present study applied the conservation of resources (COR) theory to develop a framework. It found that positive meaning in work had inverse relationships with all aspects of JBO. The negative influence of meaning-making through work significantly affected emotional exhaustion (EE) but not depersonalization (DP) and reduced personal accomplishment (RPA). The study recommends that operators and managers of classified hotels recognize the importance of boosting …

Polyaniline Nano Films Synthesis In One Step Via Chemical Oxidative Polymerization, Amal Shakir Abbood, Ibraheem Jaleel Ibraheem

Baghdad Science Journal

Polyaniline films were successfully synthesized in this study using an oxidative polymerization method at temperatures ranging from 0 to 4 ° C. Polyaniline films were deposited using a single step of chemical oxidative polymerization rather than electrochemical polymerization. The polyaniline was examined using FTIR, XRD, SEM, AFM, and Four Point Probe. This result demonstrates that polyaniline synthesized using this method has a uniform morphology, small size (17 to 40) nm, high crystallinity, and high conductivity (9.42 s/cm).

The Role Of Chlorella Vulgaris In Reducing Some Pharmaceutical Wastes Toxicity In Clam Pseudodontopsis Euphraticus, Zahraa H. Obaid, Nuha F. Kadhim, Jasim Mohammed Salman

Baghdad Science Journal

Applications of microalgae in environmental studies have recently increased. Current uses of immobilized microalga Chlorella vulgaris include reducing pharmaceutical substances such as amoxicillin AMX and potassium dichromate K2Cr2O7 on freshwater clam Pseudodontopsis euphraticus as a biotic model. Recent research pointed out a change in biomarkers of oxidative stress in an evaluation of induced toxicity. Where clams were exposed to different concentrations100, 200, and 400 mg/L for 7 days and 20, 30, and 50 mg/L for 5 days of amoxicillin and potassium dichromate, respectively. The results showed that exposure to AMX and K2Cr2O7 led to a significant change in the activity …

The Affective Embeddings Of Gacha Games: Aesthetic Assemblages And The Mediated Expression Of The Self, Orlando Woods

Research Collection School of Social Sciences

This paper argues that the motivations for investing money in gacha games can be a function of the affective embedding of players within the game, and the game within broader circuits of cultural affinity and appeal. Whilst research on gacha games – and the specific role of loot boxes therein – has emphasised their associations with gambling, I contend that affect is another trigger that can motivate seemingly irrational playing behaviours. The affective embeddings of gacha games motivate players to curate aesthetic assemblages of virtual content that enable the mediated expression of the self. Drawing on qualitative data generated amongst …

Public Service Motivation And Job Satisfaction Amid Covid-19: Exploring The Effects Of Work Environment Changes, Seulki Lee, Chongmin Na

Research Collection School of Social Sciences

The COVID-19 pandemic has brought critical changes to job demands and resources, which in turn affect employee motivation and outcomes. This study explores how COVID-19–induced work intensity and COVID-19–related organizational support influence public service motivation (PSM) and job satisfaction. Using survey data from a nationally representative sample of 1,430 South Korean central government employees collected during the pandemic (May–June 2020), we find that COVID-19–induced work intensity is positively associated with PSM, which in turn has a positive association with job satisfaction. We also find that COVID-19–related organizational support has both direct and indirect associations with job satisfaction through PSM. These …

Merit And Inequality: Confucian And Communitarian Perspectives On Singapore's Meritocracy, Sor-Hoon Tan

Research Collection School of Social Sciences

This paper compares criticisms of Singapore’s meritocracy, especially against its impact on income disparities and class divisions, with Michael Sandel’s critique of the meritocratic ethic in the United States. Despite significant differences in their history and politics, meritocracy has similar dysfunctions in both societies, allowing us to draw theoretical conclusions about meritocracy as an ideal of governance. It then contrasts Sandel’s communitarian critique of meritocracy with recent Confucian promotion of political meritocracy and meritocratic justice and argues that the Confucian principle of “promoting the virtuous and talented” is different from the contemporary conception of meritocracy. Textual evidence indicates that a …

Artificial Intelligence Model Predicts Sudden Cardiac Arrest Manifesting With Pulseless Electric Activity Versus Ventricular Fibrillation, Hoang Nhat Pham, Angelo Salvucci, Jonathan Jui, Kyndaron Reinier, Piotr J Slomka, Sumeet S Chugh

Faculty, Staff and Student Publications

BACKGROUND: There is no specific treatment for sudden cardiac arrest (SCA) manifesting as pulseless electric activity (PEA) and survival rates are low; unlike ventricular fibrillation (VF), which is treatable by defibrillation. Development of novel treatments requires fundamental clinical studies, but access to the true initial rhythm has been a limiting factor.

METHODS: Using demographics and detailed clinical variables, we trained and tested an AI model (extreme gradient boosting) to differentiate PEA-SCA versus VF-SCA in a novel setting that provided the true initial rhythm. A subgroup of SCAs are witnessed by emergency medical services personnel, and because the response time is …

Major Questions About Presidentialism: Untangling The “Chain Of Dependence” Across Administrative Law, Jodi L. Short, Jed Handelsman Shugerman

Faculty Scholarship

A contradiction about the role of the president has emerged between the Roberts Court’s Article II jurisprudence and its Major Questions Doctrine jurisprudence. In its appointment and removal decisions, the Roberts Court claims that the president is the “most democratic and politically accountable official in Government” because the president is “directly accountable to the people through regular elections,” an audacious new interpretation of Article II; and it argues that tight presidential control of agency officials lends democratic legitimacy to the administrative state. We identify these twin arguments about the “directly accountable president” and the “chain of dependence” as the foundation …

Sports Participation By Athletes With Cardiovascular Disease, Matthew W. Martinez, Michael J. Ackerman, George J. Annas, Aaron L. Baggish, Sharlene M. Day, Kimberly G. Harmon, Jonathan H. Kim, Benjamin D. Levine, Margot Putukian, Rachel Lampert

Faculty Scholarship

Millions of young people participate in competitive sports, with well-documented physical and psychological benefits.1 Athletes may be diagnosed with cardiovascular disease (CVD) during evaluation of symptoms, routine preparticipation screening, or clinically indicated family screening. When this occurs, decisions about return-to-play (RTP) are difficult, especially in circumstances when risk may exist or be unknown. Historically, expert consensus documents such as the Bethesda Conference Proceedings,2 provided a “yes/no” approach to RTP after a diagnosis of a CVD such as hypertrophic cardiomyopathy (HCM) or long QT syndrome (LQTS). These recommendations were made with a paucity of data, and were predicated on a zero-risk …
