Aesthetic-Ethical-Political Movements In Professional Learning: Encounters With Feminist New Materialisms And Reggio Emilia In Early Childhood Research, Stefania Giamminuti, Jane Merewether, Mindy Blaise

Research outputs 2014 to 2021

© 2020 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Professional learning is considered essential for early childhood teachers, and is frequently associated with childhood outcomes and dominant constructs of quality which perpetuate neoliberal ideals and position early childhood teachers within a framework of rationality, privileging discourses of masculinity and power. By engaging with feminist new materialist perspectives, with the concept of ‘movement’, and with the theory-practice of the educational project of the city of Reggio Emilia, Italy, this paper extends understandings of professional learning to include nonhuman others as worthy interlocutors, and puts forth …

Tripping Over The Other: Could Psychedelics Increase Empathy?, Emily Blatchford, Stephen Bright, Liam Engel

Research outputs 2014 to 2021

There is increasing evidence that psychedelic-assisted psychotherapy is effective for a range of psy-chological conditions. There are likely numerous mechanisms of action that contribute to these clinicaleffects. One such mechanism of action might involve psychedelics increasing levels of empathicfunctioning. This paper synthesises research concerning the relationship between psychedelics andempathy, emphasising neuroscientific and clinical contexts. We conclude that neuropsychological andclinical evidence imply psychedelics could lead to increased empathic functioning. The effects of psy-chedelics on the 5-HT system, default mode network, neural connectivity and ego dissolution areimplicated in these changes. Changes in empathic functioning also likely relate to increases in thepersonality trait …

Hiding In Plain Sight: The Globally Distributed Bacterial Candidate Phylum Pauc34f, Michael L. Chen, Eric D. Becraft, Maria Pachiadaki, Julia M. Brown, Jessica K. Jarett, Josep M. Gasol, Nikolai V. Ravin, Duane P. Moser, Takuro Nunoura, Gerhard J. Herndl, Tanja Woyke, Ramunas Stepanauskas

Research outputs 2014 to 2021

Bacterial candidate phylum PAUC34f was originally discovered in marine sponges and is widely considered to be composed of sponge symbionts. Here, we report 21 single amplified genomes (SAGs) of PAUC34f from a variety of environments, including the dark ocean, lake sediments, and a terrestrial aquifer. The diverse origins of the SAGs and the results of metagenome fragment recruitment suggest that some PAUC34f lineages represent relatively abundant, free-living cells in environments other than sponge microbiomes, including the deep ocean. Both phylogenetic and biogeographic patterns, as well as genome content analyses suggest that PAUC34f associations with hosts evolved independently multiple times, while …

Visual Flight Into Instrument Meteorological Condition: A Post Accident Analysis, Ayiei Ayiei, John Murray, Graham Wild

Research outputs 2014 to 2021

The phenomenon of encountering instrument meteorological conditions (IMCs) while operating an aircraft under visual flight rules (VFRs) remains a primary area of concern. Studies have established that pilots operating under VFRs that continue to operate under IMCs remains a significant cause of accidents in general aviation (GA), resulting in hundreds of fatalities. This research used the Australian Transport Safety Bureau (ATSB) database, which contained a total of 196 VFR to IMC occurrences, from 2003 to 2019, with 26 having formal reports. An explanatory design was adopted, commencing with a qualitative study of the 26 occurrences with reports followed by a …

Application Of A Brain-Inspired Spiking Neural Network Architecture To Odor Data Classification, Anup Vanarse, Josafath Israel Espinosa-Ramos, Adam Osseiran, Alexander Rassau, Nikola Kasabov

Research outputs 2014 to 2021

Existing methods in neuromorphic olfaction mainly focus on implementing the data transformation based on the neurobiological architecture of the olfactory pathway. While the transformation is pivotal for the sparse spike-based representation of odor data, classification techniques based on the bio-computations of the higher brain areas, which process the spiking data for identification of odor, remain largely unexplored. This paper argues that brain-inspired spiking neural networks constitute a promising approach for the next generation of machine intelligence for odor data processing. Inspired by principles of brain information processing, here we propose the first spiking neural network method and associated deep machine …

A Multipurpose Desalination, Cooling, And Air-Conditioning System Powered By Waste Heat Recovery From Submarine Diesel Exhaust Fumes And Cooling Water, Abdellah Shafieian, Mehdi Khiadani

Research outputs 2014 to 2021

The role of cooling and air-conditioning systems in submarines is assessed as indispensable, and a reliable water supply is essential for both crew and equipment. At the same time, the large amounts of high-temperature exhaust fumes discharged from submarine engines provide an excellent opportunity to recover and apply this waste energy in required applications. This paper introduces a novel multipurpose desalination, cooling, and air-conditioning system to recover waste heat from both the exhaust fumes and the cooling water of submarine engines. The whole system is mathematically modelled and analysed based on the actual thermo-physical parameters of the engine's exhaust fumes. …

Seagrass Losses Since Mid‐20th Century Fuelled Co2 Emissions From Soil Carbon Stocks, Cristian Salinas, Carlos M. Duarte, Paul Lavery, Pere Masque´, Ariane Arias-Ortiz, Javier X. Leon, David Callaghan, Gary A. Kendrick, Oscar Serrano

Research outputs 2014 to 2021

Seagrass meadows store globally significant organic carbon (C_org) stocks which, if disturbed, can lead to CO₂ emissions, contributing to climate change. Eutrophication and thermal stress continue to be a major cause of seagrass decline worldwide, but the associated CO₂ emissions remain poorly understood. This study presents comprehensive estimates of seagrass soil C_org erosion following eutrophication‐driven seagrass loss in Cockburn Sound (23 km² between 1960s and 1990s) and identifies the main drivers. We estimate that shallow seagrass meadows ( < 5 m depth) had significantly higher C_org stocks in 50 cm thick soils (4.5 ± 0.7 kg C_org/m²) …

Research outputs 2014 to 2021

Background Accurate and detailed measurement of a dancer’s training volume is a key requirement to understanding the relationship between a dancer’s pain and training volume. Currently, no system capable of quantifying a dancer’s training volume, with respect to specific movement activities, exists. The application of machine learning models to wearable sensor data for human activity recognition in sport has previously been applied to cricket, tennis and rugby. Thus, the purpose of this study was to develop a human activity recognition system using wearable sensor data to accurately identify key ballet movements (jumping and lifting the leg). Our primary objective was …

Which Dual-Band Infrared Indices Are Optimum For Identifying Aerosol Compositional Change Using Himawari-8 Data?, Miles Sowden, D Blake

Research outputs 2014 to 2021

Aerosol optical depth algorithms predominantly use the visible portion of the electromagnetic spectrum. However, quantifying sporadic dust events throughout the full 24-h period requires using continuous wavelengths such as infrared (IR). Identifying aerosols, using IR from geostationary data, has relied on subtraction indices rather than normalised differences. Limited attention has been given to determining which IR indices could be suitable for identifying aerosol compositional change. Suitable IR indices could potentially result in multi-spectral data from geostationary satellites, such as Himawari, being used to separate dust from other types of aerosols.

This study evaluated three index types: subtraction (brightness temperature difference …

Enhanced Label Free Normal And Cancer Cells Classification Using Combined Parametric Modeling And Optical Techniques, Ayshathul Fouzia Abdul Gani

Dissertations

The development of label-free methods for cell classifications has been driven by the importance of early detection and identification of cancer disease. The future point-of-care (POC) treatment methods require rapid and real-time cancer screening techniques. As the labelled methods of cell classification are time-consuming processes and require a large amount of sample preparation along with skilled persons, they do not appear to be suitable for POC treatment methods. This necessitates the importance of such development. The label-free methods incorporate the biophysical properties of cells instead of biomarkers. The optical properties of cells have been frequently utilized for cell classification. This …

The Conservation Of Variation In Gryllodes Sigillatus And Closely Related Cricket Species, Jeremy David Dalos

Biological Sciences

The ability to adjust behaviors to a particular environment has been well documented across taxa. Our understanding of behavioral plasticity is largely based on experiments in which individuals have a single exposure to an environment. Observed behavioral changes are then traditionally measured in small windows of responsiveness in a single population or species. In this project I investigated the effects of prolonged exposure to predator cues in Gryllodes sigillatus and also tested for the presence of trans-generational effects of this prolonged exposure. I found there were no differences in anti-predator behaviors when measured in subsequent assays compared to control individuals. …

Aging And Early Life Stress: Telomerase Dynamics And The Consequences For Telomeres In A Wild Bird, Jennifer Teresa Vangorder-Braid

Biological Sciences

Aging is an underlying risk factor for many major diseases including cancer, cardiovascular disease, and neurodegeneration. Yet we still do not know the full extent of how our bodies age and what determines our lifespan. One mechanism that may play an important role are telomeres, which are protective caps at the end of chromosomes. Telomeres are directly linked to longevity and can be lengthened by the enzyme telomerase. Early life telomere length is critical for lifespan, but we do not know how telomerase performs during this period. Whether variation in telomerase levels can influence telomere length and loss during development …

Red-Winged Blackbird Migration Distance And Its Relationship With Reproduction, Michelle Rachel Angelucci Eshleman

Biological Sciences

Red-winged blackbirds (Agelaius phoeniceus) are one of the most commonly researched birds in North America. My study aims to build upon what is known about migration patterns and reproduction in this species. My first objective was to determine if individuals that breed together travel to similar overwinter locations and to investigate the similarities or differences in the timing of migratory movements. My second objective was to examine the relationship between spring migration distance and reproduction. In short, I found that female blackbirds travel to more southern overwinter locations than males. Males and females may be leaving the North Dakota region …

Biological Sciences

Efforts to improve university science education continue to emphasize the importance of active learning, including frequent formative assessment and timely feedback that helps students reach desired learning outcomes. Yet, nationwide, many instructors continue to use primarily lecture-based teaching methods, with limited use of formative assessment and feedback. Factors that affect instructor adoption and implementation of new teaching techniques include departmental norms, peer interaction, and classroom environment. In this work, a model of the impacts of departmental teaching and social norms and peer interactions on instructor innovation decision is presented. This model is then used to explore 1) instructor teaching-related interactions …

Identity Federalism In Europe And The United States, Vlad Perju

Vanderbilt Journal of Transnational Law

The turn to identity is reshaping federalism. Opposition to the policies of the Trump administration, from the travel ban to sanctuary cities and the rollback of environmental protections, has led progressives to explore more fluid and contingent forms of state identity. Conservatives, too, have sought to shift federalism away from the jurisdictional focus on limited and enumerated powers and have argued for a revival of the political safeguards of federalism, including state-based identities. This Article draws on comparative law to study identity as a political safeguard of federalism and its transformation from constitutional discourse to interpretative processes and, eventually, constitutional …

Artificial States And The Remapping Of The Middle East, Ash U. Bali

Vanderbilt Journal of Transnational Law

This Article critically examines arguments tracing contemporary crises in the Arab world to the making of the Arab state system a century ago. A series of popular and scholarly articles occasioned by the recent spate of World War I-related centenaries suggest that new boundaries be drawn in the Middle East to produce more stable nation-states. More specifically, a set of authors has advocated for different borders that would avoid ethno-sectarian conflict by designing relatively homogenous smaller states to replace multiethnic, multisectarian states like Iraq and Syria. Such proposals are significant for the underlying presumptions they reflect concerning the relationship between …

A Genome-Wide Association Study Of Cocaine Use Disorder Accounting For Phenotypic Heterogeneity And Gene–Environment Interaction, Jiangwen Sun, Henry R. Kranzler, Joel Gelernter, Jinbo Bi

Computer Science Faculty Publications

Background: Phenotypic heterogeneity and complicated gene-environment interplay in etiology are among the primary factors that hinder the identification of genetic variants associated with cocaine use disorder. Methods: To detect novel genetic variants associated with cocaine use disorder, we derived disease traits with reduced phenotypic heterogeneity using cluster analysis of a study sample (n = 9965). We then used these traits in genome-wide association tests, performed separately for 2070 African Americans and 1570 European Americans, using a new mixed model that accounted for the moderating effects of 5 childhood environmental factors. We used an independent sample (918 African Americans, 1382 European …

Hold The High-Water Line: A Transnationally Informed Coastline Protection Scheme In The United States, Charlie Spencer-Davis

Vanderbilt Journal of Transnational Law

Climate change and sea level rise degrade the environment, infrastructure, and private property along US coastlines. The magnitude of these harms will only accelerate unless the United States improves its coastal protection scheme. Informed by approaches in Israel, the United Kingdom, and China, this Note offers a dynamic solution to coastline protection by way of a federal Rolling Coastal Conservation Easements Act. The act would authorize states to develop and implement rolling easements on private coastal properties. This flexible scheme would include compensation for those landowners who grant easements to their localities, while giving private property owners the option to …

Granulosa Cell Proliferation Is Inhibited By Pge2 In The Primate Ovulatory Follicle, Patric S. Lundberg, Gil J. Moskowitz, Carmel Bellacose, Esra Demirel, Heidi A. Trau, Diane M. Duffy

Computer Science Faculty Publications

Prostaglandin E2 (PGE2) is a key paracrine mediator of ovulation. Few specific PGE2-regulated gene products have been identified, so we hypothesized that PGE2 may regulate the expression and/or activity of a network of proteins to promote ovulation. To test this concept, Ingenuity Pathway Analysis (IPA) was used to predict PGE2-regulated functionalities in the primate ovulatory follicle. Cynomolgus macaques underwent ovarian stimulation. Follicular granulosa cells were obtained before (0 h) or 36 h after an ovulatory dose of human chorionic gonadotropin (hCG), with ovulation anticipated 37-40 h after hCG. Granulosa cells were obtained from additional monkeys 36 h after treatment with …

A Heuristic Baseline Method For Metadata Extraction From Scanned Electronic Theses And Dissertations, Muntabir H. Choudhury, Jian Wu, William A. Ingam, Edward A. Fox

Computer Science Faculty Publications

Extracting metadata from scholarly papers is an important text mining problem. Widely used open-source tools such as GROBID are designed for born-digital scholarly papers but often fail for scanned documents, such as Electronic Theses and Dissertations (ETDs). Here we present a preliminary baseline work with a heuristic model to extract metadata from the cover pages of scanned ETDs. The process started with converting scanned pages into images and then text files by applying OCR tools. Then a series of carefully designed regular expressions for each field is applied, capturing patterns for seven metadata fields: titles, authors, years, degrees, academic programs, …

Addressing The Auditor Independence Puzzle: Regulatory Models And Proposal For Reform, Martin Gelter, Aurelio Gurrea-Martinez

Vanderbilt Journal of Transnational Law

Auditors play a major role in corporate governance and capital markets. Ex ante, auditors facilitate firms' access to finance by fostering trust among public investors. Ex post, auditors can prevent misbehavior and prevent financial fraud by corporate insiders. In order to fulfill these goals, however, in addition to having the adequate knowledge and expertise, auditors must perform their functions in an independent manner. Unfortunately, auditors are often subject to conflicts of interest, for example, resulting from the provision of nonaudit services but also because of the mere fact of being hired and paid by the audited company. Therefore, even if …
