Vascular Expression Of Hemoglobin Alpha In Antarctic Icefish Supports Iron Limitation As Novel Evolutionary Driver, Bruce A. Corliss, Leon J. Delalio, T. C. Stevenson Keller Iv, Alexander S. Keller, Douglas A. Keller, Bruce H. Corliss, Jody M. Beers, Shayn M. Peice, Brant E. Isakson

Graduate School of Oceanography Faculty Publications

Frigid temperatures of the Southern Ocean are known to be an evolutionary driver in Antarctic fish. For example, many fish have reduced red blood cell (RBC) concentration to minimize vascular resistance. Via the oxygen-carrying protein hemoglobin, RBCs contain the vast majority of the body’s iron, which is known to be a limiting nutrient in marine ecosystems. Since lower RBC levels also lead to reduced iron requirements, we hypothesize that low iron availability was an additional evolutionary driver of Antarctic fish speciation. Antarctic Icefish of the family Channichthyidae are known to have an extreme alteration of iron metabolism due to loss …

Discovery Of An Unrecognized Pathway Carrying Overflow Waters Toward The Faroe Bank Channel, Léon Chafik, Hjálmar Hátún, Joakim Kjellsson, Karin Margretha H. Larsen, Thomas Rossby, Barbara Berx

Graduate School of Oceanography Faculty Publications

The dense overflow waters of the Nordic Seas are an integral link and important diagnostic for the stability of the Atlantic Meridional Overturning Circulation (AMOC). The pathways feeding the overflow remain, however, poorly resolved. Here we use multiple observational platforms and an eddy-resolving ocean model to identify an unrecognized deep flow toward the Faroe Bank Channel. We demonstrate that anticyclonic wind forcing in the Nordic Seas via its regulation of the basin circulation plays a key role in activating an unrecognized overflow path from the Norwegian slope – at which times the overflow is anomalously strong. We further establish that, …

Ambiguity About Ambiguity, Philip A. Hamburger

Faculty Scholarship

Petitions for certiorari from the Supreme Court typically raise legal questions that are all too familiar, as cert ordinarily is available only to resolve circuit splits. Now and then, however, a case is “cert-worthy” precisely because it turns on something novel—even astonishing. Such is Monex v. Commodity Futures Trading Commission, in which the CFTC has been relying on ambiguity about the type of ambiguity that justifies its enforcement actions.

A Data-Driven Intermittent Online Coverage Path Planning Method For Auv-Based Bathymetric Mapping, Jianguang Shi, Mingxi Zhou

Graduate School of Oceanography Faculty Publications

Bathymetric mapping with Autonomous Underwater Vehicles (AUVs) receives increased attentions in recent years. AUVs offer a lower operational cost and smaller carbon footprint with reduced ship usage, and they can provide higher resolution data when surveying the seabed at a closer distance if compared to ships. However, advancements are still needed to improve the data quality of AUV-based surveys. Unlike mobile robots with deterministic mapping performance, multibeam sonars used in AUV-based bathymetric mapping often yields inconsistent swath width due to the varied seabed elevation and surficial properties. As a result, mapping voids may exist between planned lawnmower transects. Although this …

Selection Of Indicators For Assessing And Managing The Impacts Of Bottom Trawling On Seabed Habitats, Jan Geert Hiddink, Michel J. Kaiser, Marija Sciberras, Robert A. Mcconnaughey, Tessa Mazor, Ray Hilborn, Jeremy Collie, C. Roland Pitcher, Ana M. Parma, Petri Suuronen, Adriaan D. Rijnsdorp, Simon Jennings

Graduate School of Oceanography Faculty Publications

1. Bottom trawl fisheries are the most widespread source of anthropogenic physical disturbance to seabed habitats. Development of fisheries‐, conservation‐ and ecosystem‐based management strategies requires the selection of indicators of the impact of bottom trawling on the state of benthic biota. Many indicators have been proposed, but no rigorous test of a range of candidate indicators against nine commonly agreed criteria (concreteness, theoretical basis, public awareness, cost, measurement, historical data, sensitivity, responsiveness, specificity) has been performed.
2. Here, we collated data from 41 studies that compared the benthic biota in trawled areas with those in control locations (that were either not trawled …

Potential Effect Of Bio-Surfactants On Sea Spray Generation In Tropical Cyclone Conditions, Breanna Vanderplow, Alexander V. Soloviev, Cayla W. Dean, Brian K. Haus, Roger Lukas, Muhammad Sami, Isaac Ginis

Graduate School of Oceanography Faculty Publications

Despite significant improvement in computational and observational capabilities, predicting intensity and intensification of major tropical cyclones remains a challenge. In 2017 Hurricane Maria intensified to a Category 5 storm within 24 h, devastating Puerto Rico. In 2019 Hurricane Dorian, predicted to remain tropical storm, unexpectedly intensified into a Category 5 storm and destroyed the Bahamas. The official forecast and computer models were unable to predict rapid intensification of these storms. One possible reason for this is that key physics, including microscale processes at the air-sea interface, are poorly understood and parameterized in existing forecast models. Here we show that surfactants …

Exploring The Abundance, Metabolic Potential, And Gene Expression Of Subseafloor Chloroflexi In Million-Year-Old Oxic And Anoxic Abyssal Clay, Aurèle Vuillemin, Zak Kerrigan, Steven D'Hondt, William D. Orsi

Graduate School of Oceanography Faculty Publications

Chloroflexi are widespread in subsurface environments, and recent studies indicate that they represent a major fraction of the communities in subseafloor sediment. Here, we compare the abundance, diversity, metabolic potential, and gene expression of Chloroflexi from three abyssal sediment cores from the western North Atlantic Gyre (water depth >5400 m) covering up to 15 million years of sediment deposition, where Chloroflexi were found to represent major components of the community at all sites. Chloroflexi communities die off in oxic red clay over 10 to 15 million years, and gene expression was below detection. In contrast, Chloroflexi abundance and gene expression …

Taking Off In Africa: Critical Elements Of Aircraft Engine Manufacturer Engagement That Can Affect Airline Safety Performance, Nathan Michael Woods

Antioch University Dissertations & Theses

Original Equipment Manufacturer (OEM) is a term used in many industries to describe a company that produces parts and equipment that may be marketed by another manufacturer. In the aviation industry, the aircraft engine OEM refers to the company the manufactures engines powering the aircraft. The OEM manufactures the engine, defines the required maintenance to operate the engines, and recommends product modifications. Product modifications are recommended to improve product safety, durability, reliability, and cost of ownership and are formally communicated through issuance of service bulletins. Properly performing the required maintenance and adopting service bulletins is an important element of maintaining …

Police Officer Trauma In Rural Minnesota: A Narrative Study, John J. Littlewolf

Antioch University Dissertations & Theses

We call on police officers to respond to all of society’s tragedies. Whether in our metropolitan areas or our rural communities, law enforcement will respond when called upon. The culture of law enforcement is laden with traits of masculinity. These cultural traits can inhibit the processing of traumatic experiences in the individual. While the nature of law enforcement has remained the same, our scientific knowledge regarding trauma has grown. Trauma has a biological impact which can manifest as stress symptomology or PTSD. Our systematic response to trauma in law enforcement has not kept pace with the body of knowledge on …

Generative Leadership And The Life Of Aurelia Erskine Brazeal, A Trailblazing African American Female Foreign Service Officer, Atim Eneida George

Antioch University Dissertations & Theses

There is a gap in the literature on generativity and the leadership philosophy and praxis of African American Female Foreign Service Officers (AAFFSOs). I addressed this deficit, in part, by engaging an individual of exceptional merit and distinction—Aurelia Erskine Brazeal—as an exemplar of AAFFSOs. Using qualitative research methods of portraiture and oral history, supplemented by collage, mind mapping and word clouds, this study examined Brazeal’s formative years in the segregated South and the extraordinary steps her parents took to protect her from the toxic effects of racism and legal segregation. In addition, I explored the development of Brazeal’s interest in …

An Exploration Of Factors Influencing First-Generation College Students' Ability To Graduate College: A Delphi Study, Ashley C. Gray Benson

Antioch University Dissertations & Theses

This dissertation serves as a counter-narrative to the standard deficiency model in published research that characterizes most first-generation college students as feeble and unequipped when it comes to thriving in, persisting in, and graduating from college. This is one of the few studies that examines the success of first-generation college students from the students’ perspective. First-generation college students who graduated from college participated in a Delphi study that addressed this question: What factors influence first-generation college students' ability to graduate college? Three rounds of data collection resulted in ten themes, roughly in order of importance based on feedback from study …

Confusing Conversations: Assessing Traumatic Stress In Young Children, Jennifer Lela Moniz

Antioch University Dissertations & Theses

Early detection and interventions are important for the prevention of negative long-term effects of Posttraumatic Stress Disorder (PTSD). Current evaluations of PTSD in young children rely heavily on caregiver reports, and there are few self-report measures for children under 8 years old (Mash & Barkley, 2007). This study examined the construct validity of the Post Traumatic Symptom Inventory for Children (PT-SIC), a self-report measure of PTSD symptomatology for young children, through a comparison of results with the Trauma Symptom Checklist for Young Children (TSCYC), an empirically supported caregiver measure of child PTSD symptomatology. Results of the Spearman correlation indicated that …

Cultural Constructions Of Sexual Relationships Between Female Teachers And Male Students, Tessa M. Palmer

Antioch University Dissertations & Theses

While examples of sexual relationships between male high school teachers and female students have been historically prominent, relationships wherein the respective genders are reversed have received increased attention. Research on perceptions of sexual relationships between female high school teachers and their male students has focused primarily on the perceived differences between these relationships and those between male high school teachers and their female students. To explain the effect that gender appears to have on the perceptions of sexual relationships between female high school teachers and their male students, much of the literature has pointed to cultural constructions of gender, which …

Turning Around Small, Private, Tuition Dependent Colleges: How Boards Of Trustees Impact Decline And Turnaround, Michael Bills

Antioch University Dissertations & Theses

Even before the COVID-19 Pandemic, higher education has been facing unprecedented threats to existing business models. Small, private colleges heavily dependent on tuition revenue are particularly at risk. These at-risk small, private colleges need to make significant changes if they are to stave off decline and turn themselves around. Most of the literature on turnarounds of colleges and universities is focused primarily on the president, and is largely the reminiscences of former presidents. The board of trustees, however, is the ultimate governing authority of a college/university. If an at-risk institution needs to change in order to survive, the board must …

Integrated Care For Older Adults And Memory: A Quality Improvement Approach, Haley E. Curt

Antioch University Dissertations & Theses

Integrated care, a combination of medical and behavioral health, is necessary to address the complex needs of the rapidly growing population of adults over the age of 65 (Karel, Gratz, & Smyer, 2012). Cognitive impairment, a common issue associated with aging, is a major concern for aging adults, their caregivers and family members. Comprehensively addressing cognition, whether there is an identified impairment or not, in a primary care setting allows the individual to take advantage of their independence, be an active member of planning care and making decisions, and begin treating their disease earlier when it is more manageable (Callahan …

Client Perceptions Of The Therapy Room: Effects Of Homely Therapeutic Landscapes, Amanda Knapp

Antioch University Dissertations & Theses

There is very limited research exploring the effects of a homely therapeutic landscape design on the psychological wellbeing of clients attending outpatient psychotherapy. In particular, very little is known about the impact of office design on client perceptions of their therapist and the quality of care they anticipate receiving. Ample data support the idea of healing environments; this has important implications for the field of clinical psychology. The theoretical framework underlying this study is the Tripartite Model, which states that people view spaces as most meaningful when they promote positive feelings of comfort, belonging, and security. Focusing on college students …

Ayurvedic And Bionian Theories Of Thinking: Mental Digestion And The Truth Instinct, Jenna Labbe-Watson

Antioch University Dissertations & Theses

This theoretical paper integrates Ayurvedic and Bionian psychoanalytic theories of thinking into a new, integrative understanding of how individuals learn from experience. The relationship between knowledge, emotional experience, and the truth instinct is explored. Ayurvedic and Bionian theories describe the complexity involved in transforming raw sensory and emotional experiences into thoughts that nourish our intelligence and permit us to continually dream ourselves into being. Ayurvedic theories of intrapsychic processes and the anatomy and physiology of the mind will be explicated alongside Bionian concepts of intersubjective projective identification. For the promotion and maintenance of psychological growth, Bionian psychoanalytic thinkers describe the …

The Role Of Geospatial Information And Effective Partnerships In The Implementation Of The International Agenda For Sustainable Development, Etta Delores Jackson

Antioch University Dissertations & Theses

The former United Nations Secretary-General Ban Ki-Moon (2014), repeated the core promise in the 1986 UN Declaration on the Right to Development, in which the General Assembly called for an approach guaranteeing meaningful participation of everyone in development and the fair distribution of the benefits of that development. To this end, partnerships are central and can lead to the dignity of the citizens involved as they participate in the development of their own communities. This dissertation research conducted in Manyatta A and B in the Port City of Kisumu, Kenya sought to do just that. The purpose of this study …

A Phenomenological Inquiry Into The Client Experience Of The Psychotherapy Relationship, Mark D. Knutzen

Antioch University Dissertations & Theses

Meta-analyses have indicated that there are likely common factors across varied treatment modalities that account for the effectiveness of psychotherapy. Research has attempted to identify therapist and treatment relationship components that correlate with effective mental health treatment. Yet, there is a paucity of research directly addressing the qualitative experience of the relationship between psychotherapists and their clients.

Eight adult psychotherapy clients were interviewed regarding their experience of the psychotherapy relationship with their mental health therapist. The interviews were analyzed through the use of Interpretative Phenomenological Analysis (IPA). Seven themes emerged. Three themes related to the formation, and overall foundation of …

India’S First Period: Constitutional Doctrine And Constitutional Stability, Madhav Khosla

Faculty Scholarship

Studies on constitutional stability and endurance rarely gesture toward the role of legal doctrine. While the workings of courts are often considered in understanding how a constitutional order might be sustained, this is almost variably achieved by examining the relationship between courts and other institutions. This chapter takes a different approach and studies the way in which constitutional consolidation might also be shaped by the doctrinal orientations and forms of reasoning that courts adopt. It does so by considering the first period of Indian constitutionalism. The focus is on two specific areas: the place of the Directive Principles in India’s …

The Problem Of Humanization: Affect And Investigative Mindset In U.S. Capital Mitigation, Jesse Cheng

Social and Cultural Sciences Faculty Research and Publications

This article has two goals. First, I demonstrate the challenges that “humanization” poses for the defense as an ideal of sentencing mitigation in U.S. capital trials. Capital case procedure largely neutralizes the sympathetic effects of humanization with jurors. In addition, potential mitigation witnesses inhabit affective environs that undermine any inclination to help the defense through sympathetic testimony. Second, I explain how defense advocacy responds to humanization’s challenges. Practitioners adopt an investigative mindset that focuses on forging the conditions to cultivate relationships with mitigation witnesses. This intensive affective labor translates back into the realm of procedure through strategic maneuvers intended to …

Evaluating Flow Features For Network Application Classification, Carlos Alcantara

Open Access Theses & Dissertations

Communication networks provide the foundational services on which our modern economy depends. These services include data storage and transfer, video and voice telephony, gaming, multimedia streaming, remote invocation, and the world wide web. Communication networks are large-scale distributed systems composed of heterogeneous equipment. As a result of scale and heterogeneity, communication networks are cumbersome to manage (e.g., configure, assess performance, detect faults) by human operators. With the emergence of easily accessible network data and machine learning algorithms, there is a great opportunity to move network management towards increasing automation. Network management automation will allow for a reduced likelihood of human …

The Effect Of Waterpipe/Hookah On Platelet Function And The Impact Of Inhibition Of Gβγ Subunits On Hemostasis And Thrombogenesis, Ahmed Alarabi

Open Access Theses & Dissertations

Abstract (Hookah)

Cardiovascular diseases (CVD’s) is a major public health problem. Among CVD’s risk factors, tobacco smoking is considered the single most preventable cause of death, with thrombosis being the main mechanism of CVD’s mortality in smokers. While tobacco smoking has been on the decline, the use of waterpipe/hookah has been rising, mainly due to the perception that they are “less harmful” than regular cigarettes. Strikingly, there are few studies on the negative effects of waterpipes on the cardiovascular system, and none regarding their direct contribution to thrombus formation. We employed a waterpipe whole-body exposure protocol that mimics real‐life human …

Does The Type Of Housing A Child Lives In Predict Blood Lead Level?, Elizabeth Alvarado Navarro

Open Access Theses & Dissertations

Background and Significance: Childhood lead exposure continues to be a global health problem that can compromise children's long-term health. Identifying factors that predict which children may be at the highest risk of exposure is a strategy that could help focus child lead surveillance. Lead is a natural element found in small amounts in the earth's crust and has been widely used in industry and consumer products since the time of the Romans. Lead, however, is highly toxic for humans and serves no biological purpose in the human body. There is substantial evidence that, even at the lowest levels of exposure, …

Lévy Processes: Characterizing Volcanic And Financial Time Series, Peter Kwadwo Asante

Open Access Theses & Dissertations

In this work, we use the Diffusion Entropy Analysis (DEA) to analyze and detect the scaling properties of time series from both emerging and well established markets as well as volcanic eruptions recorded by a seismic station, both financial and volcanic time series data are known to have high frequencies (i.e they are collected at an extremely fine scale). The objective is to determine the characterization i.e whether they follow a Gaussian or Lévy distribution. If they do follow a Lévy distribution we are then interested in finding if they are characterized by a Lévy walk which has a finite …

A Survey Of The Current State Of The Practice In Bridging The Gap Between Engineering Ontologies And Modeling Profiles For Engineering Applications, John Artus

Open Access Theses & Dissertations

Model-Based Systems Engineering holds the promise of enhancing systems engineering tasks and product quality through better, more efficient exchange of data across tools, personnel, and departments, a higher quality of analysis resulting from greater access to cross-discipline data, better coordination between engineering activities and those of program management, and many other benefits. Yet, there is still no standardized method for achieving commonality of architecture vocabulary across projects, across, companies, across industries such that entities operating in the same domain produce products that speak the same technical language. Some specialized domains, such as the Department of Defense (DoD), have developed Architecture …

Fabrication, Development, And Characterization Of Hipco Swcnt - Alginate Hydrogel Composites For Cellular Product Applications, Fabian Armando Alvarez-Primo

Open Access Theses & Dissertations

In this study, we designed, synthesized, and characterized ultrahigh purity single-walled carbon nanotube (SWCNT)-alginate hydrogel composites. Among the parameters of importance in the formation of an alginate-based hydrogel composite with single-walled carbon nanotubes, are their varying degrees of purity, their particulate agglomeration and their dose-dependent correlation to cell viability, all of which have an impact on the resultant compositeâ??s efficiency and effectiveness towards biomedical applications. To promote their homogenous dispersion by preventing agglomeration of the SWCNT, at first, we used three different surfactants-sodium dodecyl sulfate (SDS-anionic), cetyltrimethylammonium bromide (CTAB-cationic), and Pluronic F108 (nonionic). After experimentation and corroboration through evidence obtained …
