Dissolved organic carbon (DOC) in coastal waters is integral to biogeochemical cycling, but global and regional drivers of DOC are still uncertain. In this study we explored spatial and temporal differences in DOC concentrations and stocks across the global coastal ocean, and how these relate to temperature and salinity. We estimated a global median coastal DOC stock of 3.15 Pg C (interquartile range (IQR) = 0.85 Pg C), with median DOC concentrations being 2.2 times higher than in open ocean surface waters. Globally and seasonally, salinity was the main driver of DOC with concentrations correlated negatively with salinity, without a …

A Review Of Contact Dependent Interactions Among Encrusting Bryozoans, Sheena Emily Stephens-Norton

Cal Poly Humboldt theses and projects

This review of published literature is focused on bryozoan interactions and discusses overgrowths, “stalemates,” erect bi-laminate growths and fusions. Overgrowths, where one colony grows zooids atop another, have received the most attention in the scientific literature. Stalemates, where two colonies cease growth at the region of contact, have received relatively little research investigating the possible reasons for its occurrence. Erect, bi-laminate growth, following inter- and/or intraspecific contact between colonies, has also received little research, but could reflect mutualistic behavior of encrusting species to increase feeding and reproduction. Fusion of self-self-contacts appears common, yet non-self-fusions to form natural chimeras may also …

Diversity Statements, Academic Freedom, And The First Amendment, Keith E. Whittington

Nebraska Law Review

Diversity statements have become a common component of applications for faculty positions and student admission at universities across the country. They have also become politically controversial, with several states banning the use of such requirements at public universities. The use of diversity statements also raises difficult constitutional questions under the First Amendment at public universities and academic freedom questions at both public and private universities. Although there are versions of such statements that might pass constitutional muster, as commonly designed and implemented, the use of diversity statements likely violates both First Amendment and academic freedom principles. Indeed, diversity statement requirements …

Safe Data-Enabled Control Of Human-In-The-Loop Robotic Manipulator Systems, Ritirupa Dey, Avimanyu Sahoo, Vignesh Narayanan

Publications

Safe control of human-in-the-loop (HIL) robotic manipulators is critical for applications such as assistive robotics, teleoperation in hazardous environments, and collaborative manufacturing. However, this remains challenging due to the lack of a unified framework that simultaneously addresses safety constraints, external disturbances, unmodeled dynamics, and dynamic role switching in the HIL setting. In this paper, we propose a novel NN-driven HIL control framework in which human–robot dyadic interaction occurs through the haptic channel. Using Lyapunov stability analysis, we theoretically show that the proposed NN-based controller ensures accurate joint trajectory tracking, compensates for system uncertainties, and adapts to human inputs modeled as …

The Theoretical And Practical Limits Of Kolmogorov-Zurbenko Periodograms With Dynamic Smoothing In The Spectral Analysis Of Time Series Data, Barry M. Loneck

Electronic Theses & Dissertations (2024 - present)

The purpose of this Dissertation was to establish the theoretical and practical limits of Kolmogorov-Zurbenko periodograms with dynamic smoothing in contrast to standard periodograms with static smoothing, along with a practical application of Kolmogorov-Zurbenko time series analysis methods. It was determined that Kolmogorov-Zurbenko periodograms with dynamic smoothing were superior to standard periodograms with static smoothing in estimating signal frequencies with respect to sensitivity, accuracy, and resolution, and that they are robust in the face of missing data. However, their precision in estimating signal strength exceeds that of standard periodograms with static smoothing in only the most extreme circumstances and, thus, …

Socio-Economic And Infrastructural Determinants Of Response Time Disparities Across Emergency Service Agencies, Alice N. Ottah

Electronic Theses & Dissertations (2024 - present)

This study comprehensively analyzes the determinants of disparities in emergency response times for EMS, Fire, and Police agencies in San Francisco from 2021 to 2023, utilizing a multilevel modeling framework and publicly accessible data. Contrary to a primary reliance on structural neighborhood factors, this research reveals that while neighborhood disadvantage statistically significantly interacts with agency type to influence response times, its direct effect is weak and not uniformly consistent across services. Specifically, the analysis demonstrates that variance in call response times across neighborhoods is minimal (Intraclass Correlation Coefficients < 0.02), the effects of disadvantage are agency-specific (null effects for Police and Fire), and even when significant (for EMS calls only), response times are faster in more disadvantaged neighborhoods. These findings challenge the existing literature on emergency response times and highlight the need for tailored policy interventions that consider both neighborhood context and agency-specific operations to promote equitable emergency response.

Complex Missing Data Problems In Education Surveys, Thomas Wesley Robertson

Electronic Theses & Dissertations (2024 - present)

Missing data are a nearly universal problem in human subjects research, including in education. However, reporting and addressing missing data is an issue, despite guidelines from the APA style guide and the What Works Clearinghouse, as well as guidance from prominent statisticians on the best methods to use. Prior research conducted in 2004 and 2014 found that in the field of education, most studies do not report or address missing data. In addition, no study has looked specifically at how missing data are reported and addressed in complex surveys. The current study has two main objectives: first, to determine if …

Investigating Rna Dysfunction Of Inherited Neuromuscular And Neurodevelopmental Disease, Jacob H. Schroader

Electronic Theses & Dissertations (2024 - present)

ITPase deficiency is a rare but fatal, autosomal recessive enzyme deficiency involving encephalopathy, microcephaly, congenital cataracts, hypotonia, developmental delay, and dilated cardiomyopathy. Within a decade since the original description of the severe form in humans, there are huge gaps in the field regarding the underlying molecular mechanisms driving pathogenesis resulting from ITPase deficiency. Past studies have focused on characterization of the organism level ITPase-deficient phenotype, but the molecular and cellular characterization remains to be fully described. Due to the biochemical function and established biological role of the ITPase enzyme, investigation into the consequences of inosine accumulation and misincorporation into RNA …

Nola 2150, Kristopher Ferber

Electronic Theses & Dissertations (2024 - present)

Abstract

Speculative fiction often takes a dystopic approach where authors envision what will be lost from books being banned in Fahrenheit 451 to us losing our civil liberties in 1984 to most of humanity being wiped out by an engineered virus in Oryx and Crake. This creative thesis takes a more optimistic approach by the act of preservation. In this case the city of New Orleans thriving as an underwater city protected by a glass dome in the year 2150. The city’s vibrant culture remains the same despite being almost too close to comfort to marine life. This work …

Buoy-Based Eddy Covariance Drag Coefficient At A Near-Shore And Offshore Site, David P. Marcial

Electronic Theses & Dissertations (2024 - present)

An eddy covariance (EC) flux system was integrated onto a Navy Oceanographic Meteorological Automatic Device (NOMAD) floating lidar buoy fitted for measuring the offshore wind resource. The EC flux system consisted of two sonic anemometers and an inertial measurement unit that together provided high-frequency (10 Hz) motion-corrected wind measurements. To assess possible impacts of flow distortion, EC momentum fluxes (10 min) were calculated in gravity-aligned, natural, and planar fit (PF) coordinate frames. The buoy was anchored near the Martha’s Vineyard Coastal Observatory Air-Sea Interaction Tower (ASIT; near-shore) for validation of the buoy-based EC fluxes against the fixed tower measurements before …

A Computational Fluid Dynamics (Cfd) Based Assessment Of Animal Borne Data Logger Impact, Christopher Pass

School of Engineering, Computing and Mathematics Theses

Animal borne data loggers are powerful tools that provide researchers with valuable insight into the behaviour and ecology of free-ranging marine animals. Despite their usefulness, the addition of a tag inevitably alters the forces acting on a swimming body and can increase the energetic cost of swimming. Computational Fluid Dynamics (CFD) tools offer a powerful means of assessing tag impact and a number of previous works have employed CFD to this end but have typically been based on a range of simplifying assumptions. Chief amongst these simplifications is that animals can be modelled as rigid bodies with a simple tag …

Revisiting The Shortage Of Seafaring Officers: Insights From Chinese And Philippine Statistics, Lijun Tang

Plymouth Business School

This paper analyses statistical data on Chinese and Filipino seafarers released by their respective maritime authorities. The analysis suggests a mismatch in the market - an oversupply of cadets and junior officers coupled with a shortage of senior officers. This mismatch is underpinned by two structural issues in the labour market. Firstly, the occupational structure means that ships are likely to be manned by equal numbers of junior and senior officers. However, due to attrition, there are not enough junior officers in the industry to allow them to progress to senior ranks. Secondly, nationality segmentation creates a glass ceiling for …

Racializing Three Strikes, G. Ben Cohen, Justin D. Levinson, Koichi Hioki

Akron Law Faculty Publications

"Three Strikes” laws sit at the fulcrum of racial disparities and mass incarceration. Despite clarity across decades that such laws have served to disproportionately punish Black Americans, legislatures have blessed them, courts permit them, prosecutors charge them, and juries convict based on them. Although it has long been clear that these laws have played a key role in the racialization of America's criminal justice system, less clear are the mechanisms that drive and permit the embrace of this racialization. In this Article, we test empirically in a national study the hypothesis that Three Strikes laws exist because of race, are …

The Faster Horse Fallacy: How The Law Idealizes Technology, Yunsieg P. Kim

Hofstra Law Faculty Scholarship

How does the legal profession understand new technology? Lawyers are involuntary experts in technology: we are not professionally trained in technology like engineers are but must know technology better than the typical citizen does, because the law must regulate how the typical citizen that is, society uses technology. The increasing complexity and variety of technologies that affect everyday life, such as artificial intelligence (AI), make our jobs as involuntary experts in technology all the more important. To prepare lawyers to regulate technology effectively, we must first examine how lawyers understand (or misunderstand) technology in the present. This Article examines a …
