The Impact Of Affiliative Motivation And Trust On Confrontations Of Racism, Jamie Patrianakos

Dissertations

Anti-Black racism persists in the United States with harmful consequences for Black people. White people are able to disrupt the racial status quo and propel the conversation about racial justice forward by confronting racism. Confronting perpetrators of racism can reduce prejudice, yet people hesitate to confront because they fear social backlash, even from those with whom they share a social bond. Two online studies asked participants to complete a task eliciting stereotypical responding while being observed by a supposed interaction partner with whom they shared either a high or low desire to get along. Participants were confronted by their interaction …

A Time And Place: Structures Of Knowledge At An Archeological Field-Site, Joseph Renow

Dissertations

In regards to the places where it happens, our shared beliefs about science encompass two seemingly contradictory positions. On the one hand, scientific-knowledge is understood as universal, and as being tied to nowhere in particular. On the other hand, we believe science cannot happen just anywhere, and more often than not, we imagine it at home in the highly controlled and cleansed environments of laboratories. In this dissertation I utilize ethnographic data collected at Angel Mounds (an active archeological field-site and museum) to describe somewhere very different than where we typically imagine science occurring. At Angel Mounds science is deeply …

Wastewater Treatment Alters Microbial Colonization Of Microplastics, John J. Kelly, Maxwell G. London, Amanda R. Mccormick, Miguel Rojas, John W. Scott, Timothy J. Hoellein

Biology: Faculty Publications and Other Works

Microplastics are ubiquitous contaminants in aquatic habitats globally, and wastewater treatment plants (WWTPs) are point sources of microplastics. Within aquatic habitats microplastics are colonized by microbial biofilms, which can include pathogenic taxa and taxa associated with plastic breakdown. Microplastics enter WWTPs in sewage and exit in sludge or effluent, but the role that WWTPs play in establishing or modifying microplastic bacterial assemblages is unknown. We analyzed microplastics and associated biofilms in raw sewage, effluent water, and sludge from two WWTPs. Both plants retained >99% of influent microplastics in sludge, and sludge microplastics showed higher bacterial species richness and higher abundance …

Promoting Early-Adolescent Dual Language Learners' Language Use & Reading Skills, Holly Griskell

Dissertations

Most studies of Dual Language Learners’ (DLLs’) literacy development focus on the early childhood years. As such, this three-study dissertation sought to advance our knowledge of DLLs’ English language and reading comprehension skills during early adolescence, a developmental stage when many students struggle with reading. Study 1, “Classroom Discussion and Early-Adolescent Dual Language Learners’ Motivation and Reading Comprehension”, considered how features of the classroom language environment promote DLLs’ reading comprehension skills. We examined relations between students’ (N = 413; M age = 11.66-years-old) engagement in high-quality classroom discussions and reading comprehension as a function of their motivation to participate in …

Secularism, The Oxford Movement, And Religious Aesthetics In John Keble, Christina Rossetti, Adelaide Anne Procter, And Gerard Manley Hopkins, Mary Harmon

Dissertations

This dissertation examines the relationship between secularism and the development of Oxford Movement poetry. The members of the movement sought to restore pre-Reformation religious practices in the Anglican Church while maintaining its distinctiveness from the Roman Catholic and Orthodox traditions, which led to the development of unique liturgy, architecture, hymns, and poetry, among other art forms. I argue that secularism simultaneously made the movement more possible while also making it more unstable. Secularism gave the theologians and poets of the movement enough freedom to borrow from older Christian traditions, yet the movement failed to revive the Anglican Church (several members …

God And Rescuer, Clinton Neptune

Dissertations

I argue that the best concept of God, for the purposes of inquiring into God's existence and nature, is one derived from considering the human predicament and how to satisfy the existential yearning of human inquirers. Other popular methods of conceiving of God, such as some perfect being theologies and scriptural theologies, miss this vital motivational component in their God-concept construction. The concept of God on offer in this project, God as Rescuer, characterizes a being who is willing and able to rescue humanity from the predicament of the possibility of personal death, moral failure, and apparent gratuitous evil. It …

Hemingway, Sartre, And Secularization: Finding Religion Without God, Marcos Antonio Norris

Dissertations

This dissertation intervenes in the critical debate over Ernest Hemingway’s religious orientation. One camp of Hemingway scholars argues that he was a practicing Catholic, while the other camp argues that Hemingway was an existential atheist. Rather than side with either camp in this binary debate, my research offers a third option that bridges the gap between these opposing positions. Examining Hemingway’s life and works through the eyes of contemporary political philosopher Giorgio Agamben, I argue that Hemingway is, properly speaking, neither a secularist nor a theist, but a secularized theist, whose “religion” takes the form of masculine volition, or sovereign, …

A Model For Inhalation Of Infectious Aerosol Contaminants In An Aircraft Passenger Cabin, Bert A. Silich

International Journal of Aviation, Aeronautics, and Aerospace

Aerosol contamination of an aircraft cabin by infectious passengers is a concern of passengers, aircrew and the aviation industry. This may be especially important during a pandemic, such as COVID-19, where the full extent of aerosol transmission is not well understood. A statistical method to determine the number of infectious passengers on board along with a mathematical model estimating the contaminant concentration of aerosols in the cabin and the number of inhaled infectious particles by passengers is presented. An example is used to demonstrated how the results can be estimated during normal operations and emergency conditions with malfunctions of the …

Small Unmanned Aircraft Systems Acoustic Analysis For Noninvasive Marine Mammal Response: An Exploratory Field Study, David Thirtyacre, Gennifer Brookshire, Sarah Callan, Brittany Arvizu, Patrick Sherman

International Journal of Aviation, Aeronautics, and Aerospace

As in countless other fields of human endeavor, small unmanned aircraft systems (sUAS) have the potential to benefit pinniped (Pinnipedia; e.g., Phocidae [seals], Otariidae [sea lions], and Odobenidae [walruses]) response efforts. The employment of sUAS could give responders a close-up look at animals in distress in order to determine their condition as well as develop a response strategy. However, unlike other subjects that are regularly inspected by sUAS (e.g., croplands and civil infrastructure) pinnipeds may respond to the distinctive sound generated by small, multirotor sUAS. This reaction may include retreating into the water en masse, which could put …

How Duty Rosters And Stress Relate To Sleep Problems And Fatigue Of International Pilots, Marion Venus, Martin Grosse Holtforth

International Journal of Aviation, Aeronautics, and Aerospace

While previous research focused on pilots’ fatigue, rosters, potential performance-impairment and aviation-safety, this research investigates, how pilots’ work-related and psychosocial stress and rosters can affect their sleep and fatigue. A cross-sectional online survey was completed by 192 pilots flying for European operators, 180 Australian pilots and 34 pilots from UAE, Turkey and Asia Pacific. Pilots reported their actual duty- and flight-hours, flown sectors, standby, rest, vacation days, number of early starts, night-flights and sports-hours for the last two months. Schedule-related data, way to work, age, flight-hours on the present type of aircraft, subjective job-security and psychosocial stress were used as …

Numerical Analysis Of Aerospike Engine Nozzle Performance At Various Truncation Lengths, Sam Dakka Dr, Oliver Dennison

International Journal of Aviation, Aeronautics, and Aerospace

The aerospike engine was first devised in the early 1960s where it provided new means of reaching orbit in a single stage. The paper aimes to demonstrate the viability of the technology by showcasing the increased nozzle thrust efficiency over the conventional bell nozzle. Various truncations were applied to the nozzle and each was subjected to two conditions, an over-expansion and near optimum condition. The nozzle contour was developed using the simple approximation method and was chosen to replicate that of the XRS-2200. This anchored the data, thereby validating the computational fluid dynamics (CFD) simulation. Simulations were completed for at …

Predictability Improvement Of Scheduled Flights Departure Time Variation Using Supervised Machine Learning, Deepudev Sahadevan, Palanisamy Ponnusamy Dr, Manjunath K. Nelli Mr, Varun P. Gopi Dr

International Journal of Aviation, Aeronautics, and Aerospace

The departure time uncertainty exacerbates the inaccuracy of arrival time estimation and demand for arrival slots, particularly for movements to capacity constrained airports. The Estimated Take-Off Time (ETOT) or Estimated Departure Time(ETD) for each individual flight is currently derived from Air Traffic Flow Management System (ATFMS), which are solely determined based on individual flight plan Estimated Off Block Time(EOBT) or subsequent delays updated by Airline. Even if normal weather conditions prevail, aircraft departure times will differ from ETOTs determined by the ATFMS due to a number of factors such as congestion, early/delayed inbound flight (linked flights), reactionary delays and air …

Notes On Rules Of Thumb For Pilots, Yuzo Inokuchi

International Journal of Aviation, Aeronautics, and Aerospace

The rules of thumb can be found in several flight instructions or pilot's handbooks. Thus far, available rules have been presented without proof or a valid range, such as altitude or velocity ranges wherein these rules can be applied. This paper presents the background theory for a few selected rules; then, the rule is compared with a first-order approximation of the background theory. A valid range is presented by analyzing the prediction accuracy of the rule, which is defined as the relative error of the rule to the background theory. These rules of thumb provide a good approximation of the …

Identification Of Wind-Induced Hazard Zones Impacting Uas Bridge Inspection, Jack J. Green, John Mott

International Journal of Aviation, Aeronautics, and Aerospace

Unmanned Aerial Systems (UAS) continue to grow in both popularity and utility within the national airspace system. The use of commercial UAS for civil inspection, specifically that of bridge structures, is becoming commonplace among practitioners and academics alike. The development of an integrated bridge-inspection hazard model provides a way for UAS operators to prepare for and respond to changing environmental conditions that could otherwise prevent a successful UAS flight. The interaction of wind-induced airflow with bridge surfaces creates an aerodynamic wake that can result in hazardous conditions for a UAS platform operating in close proximity. An analysis of this airflow …

Aviation Culture: A ‘Glass Sky’ For Women Pilots - Literature Review, Ivana Gorlin, Donna Bridges

International Journal of Aviation, Aeronautics, and Aerospace

This paper reports on a review of literature covering gender issues in aviation. It considers the impacts of aviation culture on women pilots. The focus of the review was on empirical studies over a 25-year period (1996-2020). Two research questions underpin the review; firstly, we investigated how aviation culture impacts women pilots’ experiences, secondly, we considered its effect on women as pilots. Using a hermeneutic methodological framework, we found that cultural attitudes towards women pilots in the aviation industry are biased and discriminatory. The studies in the review overwhelming concur that the hegemonic masculine culture that dominates aviation significantly diminishes …

Plymouth Institute of Education Theses

This research project is an inquiry into, and exploration of, work carried out by students studying on formal Further Education (FE) and Higher Education (HE) Art & Design courses in a specialist Art & Design college. The project focuses on the use of sketchbooks and the effects that new technologies are having on sketchbook practices. The sketchbook has played an important role in Art & Design practices, and education, for hundreds of years and in that time its usage had 'remained virtually untouched by the march of fashions and theories throughout history (Clayton and Weisenthal, 1991:113). But, during the late …

‘Whether The Elves Are Watching Or Not’. Listening To Teachers’ Experiences Regarding Surveillance Technologies In Schools., Martin Edward Edmonds

Plymouth Institute of Education Theses

Abstract Surveillance technologies have become a normalised aspect of the workplace, and daily life, in England. This is particularly true in schools, where CCTV (Closed Circuit Television) is commonplace, and an audit culture well established. This study explores how teachers feel the atmosphere and culture of a school is influenced by technologized surveillance tools. Three interrelated questions were explored; what effect do surveillance technologies in schools have upon relationships between colleagues and students? What is lost by the application of such surveillance technologies in schools? How can Ivan Illich’s work show us a way to respond? To explore these questions, …

Deep Learning Of Sea Surface Temperature Patterns To Identify Ocean Extremes, J. Xavier Prochaska, Peter C. Cornillon, David M. Reiman

Graduate School of Oceanography Faculty Publications

We performed an out-of-distribution (OOD) analysis of ∼12,000,000 semi-independent 128 × 128 pixel² sea surface temperature (SST) regions, which we define as cutouts, from all nighttime granules in the MODIS R2019 Level-2 public dataset to discover the most complex or extreme phenomena at the ocean’s surface. Our algorithm (ULMO) is a probabilistic autoencoder (PAE), which combines two deep learning modules: (1) an autoencoder, trained on ∼150,000 random cutouts from 2010, to represent any input cutout with a 512-dimensional latent vector akin to a (non-linear) Empirical Orthogonal Function (EOF) analysis; and (2) a normalizing flow, which maps the autoencoder’s latent …

Analysis Of Vibracores From The New Hampshire Continental Shelf From 1984 And 1988, Larry G. Ward, Rachel C. Morrison, Zachary S. Mcavoy, Maxlimer Coromoto Vallee-Anziani

Center for Coastal and Ocean Mapping

During this study, the twenty-three vibracores taken in 1984 and 1988 were reexamined, original descriptions verified and significantly expanded, and the cores sampled to provide complete grain size data (i.e. the original sediment grain size analyses were limited). The vibracores were grouped by location with respect to major physiographic features (geoforms) or surficial sediment type including Offshore Marine-Modified Glacial Features (Drumlins and Lodgement Till Deposits), Northern Sand Body, Isles of Shoals, Nearshore Marine-Modified Glacial Features (Eskers and Drumlins), Nearshore Sheet Sand, and Offshore Seafloor Plain.

The Northern Sand Body (NSB), located near the Isles of Shoals ~10 km from shore, …

New Hampshire And Vicinity Continental Shelf: Sand And Gravel Resources, Larry G. Ward, Zachary S. Mcavoy, Maxlimer Coromoto Vallee-Anziani

Center for Coastal and Ocean Mapping

The continental shelf off New Hampshire (NH) has extensive marine-modified glacial deposits and associated shoals. These features are potential targets for sand and gravel resources for beach nourishment and other efforts to build coastal resiliency. The distribution of sand and gravel deposits was evaluated based on the synthesis of relatively recent high-resolution bathymetry, new surficial sediment and geoform maps, and an extensive data archive that includes over ~1280 km of seismic profiles, ~750 grain size analyses, and 23 vibracores. This work heavily utilizes the results of previous research on mineral resources on the NH shelf by Birch (1984) …

Surficial Geology Of The Continental Shelf Off New Hampshire: Morphologic Features And Surficial Sediment, Larry G. Ward, Zachary S. Mcavoy, Maxlimer Coromoto Vallee-Anziani, Rachel C. Morrison

Center for Coastal and Ocean Mapping

The continental shelf off New Hampshire (NH) in the Western Gulf of Maine (WGOM) is extremely complex and includes extensive bedrock outcrops, marine-modified glacial deposits, marine-formed shoals, seafloor plains, and associated features that are composed of a range of sediment types from mud to gravel. Furthermore, the physiography and composition of the seafloor frequently changes dramatically over relatively short distances (tens of meters). The complexity of the WGOM seafloor results from the interplay of glaciations, sea-level fluctuations, and marine processes (waves and currents). High-resolution multibeam echosounder (MBES) bathymetry and backscatter surveys, along with ground truth consisting of archived seismic reflection …

Repercussions Of A Weak Ocean Governance And A Non-Existent Maritime Security Policy : The Resurgence Of Piracy And Armed Robbery In The Gulf Of Mexico, Adriana Avila-Zúñiga Nordfjeld, Dimitrios Dalaklis

Articles

Piracy and armed robbery attacks against vessels at anchoring areas of ports in the Southern Gulf of Mexico and oil platforms located in the region have increased significantly during the last three years. Only during the first seven months of 2020, research efforts have documented 14 piratical attacks, but only 3 of them were officially reported to the International Maritime Organization (IMO) by the attacked vessel’s flag jurisdiction and not by Mexico, the State where these incidents occurred.

Maritime Robotics And Autonomous Systems Operations : Exploring Pathways For Overcoming International Techno-Regulatory Data Barriers, Tafsir Martin Johansson, Dimitrios Dalaklis, Aspasia Pastra

Articles

The current regulatory landscape that applies to maritime service robotics, aptly termed as robotics and autonomous systems (RAS), is quite complex. When it comes to patents, there are multifarious considerations in relation to vessel survey, inspection, and maintenance processes under national and international law. Adherence is challenging, given that the traditional delivery methods are viewed as unsafe, strenuous, and laborious. Service robotics, namely micro aerial vehicles (MAVs) or drones, magnetic-wheeled crawlers (crawlers), and remotely operated vehicles (ROVs), function by relying on the architecture of the Internet of Robotic Things. The aforementioned are being introduced as time-saving apparatuses, accompanied by the …
